In the Dutch Republic during the winter of 1636–37, the price of certain rare tulip bulbs climbed to extraordinary heights — single specimens of the prized Semper Augustus and Viceroy reportedly changing hands, on paper, for sums that could buy a canal house in Amsterdam — before the market for them collapsed in the first week of February 1637. Tulip Mania is the archetypal speculative bubble: the event every later crash is measured against, and the cautionary tale most people half-know.
The defining facts are not in dispute. A genuine speculation in tulip futures inflated and then broke. What is in dispute is almost everything else. For two centuries the episode was retold as a national hysteria in which chimney sweeps and noblemen alike were ruined, despairing investors drowned themselves in canals, and the Dutch economy was shaken to its foundations. The historian Anne Goldgar, whose 2007 study Tulipmania worked from contemporary archives rather than later moralizing, found a far smaller and stranger affair: perhaps a few hundred participants, concentrated among prosperous merchants and skilled craftsmen, and not a single documented bankruptcy traceable to the crash.
The collapse was real, but its damage was largely social, not financial. Because tulip contracts were forward agreements — promises to pay in the future for bulbs still in the ground — the burst left a tangle of unenforceable debts rather than a heap of lost cash. The courts declined to enforce the contracts; most were simply never honored; the wider economy carried on. The drama lay in broken trust and wounded honor among a tightly networked trading class, not in mass beggary.
Tulip Mania therefore has two endings, and the second is the more durable. The trade collapsed in 1637. The myth was assembled later — above all by the Scottish journalist Charles Mackay in 1841 — out of Calvinist pamphlets that had mocked the speculators as a warning against greed. That caricature, not the archive, became the parable taught to every generation since. The case is a study in two delusions at once: the genuine greater-fool dynamics of 1636, and the moralizing legend that froze them into a fable.
In London in 1720, the shares of the South Sea Company rose from about £128 in January to nearly £1,000 by August and then collapsed back toward £100 before the year was out — a roughly tenfold inflation and an almost total deflation inside a single year. The South Sea Bubble was Britain’s first great stock-market crash, and the word “bubble” itself entered the financial vocabulary from it. By the time it broke in September 1720, it had ruined thousands of investors, including Sir Isaac Newton, and exposed corruption that reached into the cabinet and the court.
The South Sea Company was not, at its core, a trading venture at all. Founded in 1711, it held a monopoly on British trade with Spanish South America — a monopoly that produced almost no profit, since Spain permitted only a trickle of ships and the company’s main commerce was a brutal contract to supply enslaved Africans to the colonies. Its real business was the national debt. In 1720 the company persuaded Parliament to let it convert a large portion of Britain’s public debt into its own shares, betting that a rising share price would let it absorb government creditors cheaply and pocket the difference. The scheme depended entirely on the stock going up.
So the directors made it go up. They lent buyers money to purchase shares, accepted small down-payments on instalment “subscriptions,” spread favourable rumours, and bribed politicians with stock they could sell back at a profit. The price soared, dragging a frenzy of imitators with it — dozens of “bubble companies” floated on absurd prospectuses to ride the mania. When the South Sea Company turned the new Bubble Act against those rivals in the summer, it punctured confidence across the whole market, and its own inflated shares began to fall. The collapse was swift and merciless.
The aftermath was a national reckoning. A parliamentary Committee of Secrecy uncovered systematic fraud and bribery; the Chancellor of the Exchequer, John Aislabie, was expelled from the Commons and imprisoned; the estates of the company’s directors were confiscated to compensate the ruined. Robert Walpole, who had kept some distance from the scheme, managed the wreckage and emerged as Britain’s dominant minister — in effect its first prime minister. The bubble passed into history as the model of how political insiders and a credulous public could together inflate a worthless promise into a catastrophe.
In Paris between 1719 and 1720, the shares of John Law’s Mississippi Company rose from around 500 livres to a peak near 10,000 — a twentyfold climb in roughly a year — before collapsing back toward their starting value and dragging France’s experiment in paper money down with them. The Mississippi Bubble was the first great fiat-currency catastrophe: a scheme that fused a trading monopoly to a national bank, printed money to buy its own shares, and ended in hyperinflation, bankruptcy, and a national distrust of banks and paper that lasted generations.
Its architect was John Law, a Scottish economist, gambler, and convicted duellist who had fled Britain and won the ear of the Duke of Orléans, regent of France during the minority of Louis XV. France was crushed by debt left from the wars of Louis XIV, and Law offered a radical cure: replace scarce gold and silver with paper money issued by a bank, and use a great trading company to soak up the public debt. In 1716 he founded the Banque Générale, which became the state-backed Banque Royale; his Compagnie d’Occident, soon enlarged into the Compagnie des Indes, monopolised French colonial trade, including the vast Mississippi territory of North America.
What followed was the “System” — a self-reinforcing machine in which the bank printed notes, the public used them to buy company shares, and rising shares justified printing more notes. Speculation in the narrow Rue Quincampoix grew so frenzied that the word “millionaire” was reportedly coined there to describe the newly rich. But the wealth of the Mississippi territory was a fantasy of swamp and disease, the share price rested on nothing but expectation, and the flood of paper money far outran the gold that supposedly backed it. When investors began converting shares and notes back into coin, the System could not honour them.
The collapse through 1720 was ruinous. Attempts to prop up the price, restrict gold withdrawals, and halve the value of banknotes by decree only destroyed confidence; crowds besieged the bank, and people were reportedly crushed to death in the press to convert paper into coin. Prices spiralled into hyperinflation, fortunes evaporated, and Law fled France in December 1720, dying in poverty in Venice in 1729. France emerged so scarred that it shunned a true central bank and the word “banque” itself for decades — a delusion whose hangover outlasted the boom by a lifetime.
In Britain in the mid-1840s, the share prices of railway companies inflated into the largest speculative bubble the country had yet seen, with a railway share index that peaked around 1984 in August 1845 before falling to roughly 673 by 1850 — a loss of nearly two-thirds. Railway Mania drew in a newly prosperous middle class, including figures as eminent as Charles Darwin, John Stuart Mill, and the Brontë sisters, and when it broke it wiped out the savings of thousands of ordinary investors. Yet, unlike a tulip bulb or a Mississippi share, what it financed was real: the boom left behind much of the railway network that still serves Britain today.
The setting was a Britain transformed by the steam railway. The early lines of the 1830s had proved both technically triumphant and genuinely profitable, paying handsome dividends to their shareholders. By the mid-1840s, with interest rates low and government bonds offering meagre returns, a swelling class of savers went looking for higher yields and found them in railway shares. Parliament was flooded with proposals for new lines; promoters issued glowing prospectuses; and the press, much of it dependent on railway advertising, amplified the enthusiasm. The mania reached its zenith in 1846, when 263 Acts of Parliament authorised new railway companies for routes totalling some 9,500 miles.
The mechanism that turned investment into a bubble was the way shares were sold. A speculator could secure a holding by paying only a small deposit — often around ten per cent — with the rest of the capital “uncalled,” to be demanded later as the line was built. This let modest savers commit to far larger sums than they possessed, in the expectation of selling at a profit before the calls came due. Many of the proposed lines were duplicative, uneconomic, or fraudulent, and a large share of them were never built at all; the shares were bought not for the railways but for the resale.
When the Bank of England raised interest rates in late 1845, the cheap credit that had fed the frenzy tightened, and railway shares began a long decline. Now the uncalled capital became a trap: investors holding shares in half-built or never-built lines were legally obliged to pay the calls, draining or ruining them. The “Railway King,” George Hudson, who controlled a vast network and had paid dividends out of capital in a manner later exposed as fraudulent, was disgraced and fell from power by 1849. Thousands of middle-class families were financially destroyed. But the capital that survived built thousands of miles of track, and Railway Mania endures as the rare bubble that left a lasting public good amid the private ruin.
In the state of Florida between roughly 1924 and 1926, a speculative frenzy over coastal real estate drew hundreds of thousands of buyers chasing the promise of sunshine, cheap waterfront, and effortless wealth — and then collapsed before the rest of the United States had even entered the Great Depression. By 1925 the market for paper lots had already begun to seize; the Great Miami hurricane of 18 September 1926 finished it, and the 1928 Okeechobee hurricane buried what remained. The Florida land boom is the American archetype of a property mania, and the closest domestic rehearsal for the crash of 1929.
The defining mechanism was the “binder.” A buyer could secure a lot for a small down payment — often around ten percent — with the balance due in thirty days, before any deed changed hands. That thin slice of cash bought a contract, not a house, and the contract itself could be sold. Speculators known as “binder boys” traded these options on land they never intended to own and frequently never saw, so that a single Miami lot might be bought and sold as many as ten times in one day, each buyer pocketing the spread and passing the obligation along. It was leverage and forward trading wrapped in a real-estate skin.
The land was real, but the prices were not anchored to anything anyone could use. Developers and promoters — Carl Fisher dredging Miami Beach from mangrove, George Merrick building the planned city of Coral Gables, Addison Mizner conjuring Boca Raton — sold a vision of paradise through national advertising, celebrity endorsement, and orators who could make swamp sound like the Riviera. As long as new buyers kept stepping off the trains, every binder looked like a profit. When the buyers thinned in 1925, the chain of thirty-day obligations had no one left to pass to, and the spread that had enriched everyone reversed into debt that ruined many.
The collapse came in stages, and then all at once. Buyers stopped arriving; railroads choked on construction freight and embargoed it; a sunken ship blocked Miami’s harbor; banks that had lent against inflated land began to wobble. The September 1926 hurricane, which the Red Cross tallied to 372 deaths and which destroyed thousands of homes, ended any pretense that the boom could resume. Florida’s economy contracted years ahead of the nation’s, and the episode passed into history as the cautionary tale that almost nobody heeded three years later on Wall Street.
In New York in the autumn of 1929, the speculative bull market of the late 1920s broke apart over a few days in late October — Black Thursday on 24 October and Black Tuesday on 29 October — and the collapse helped tip the United States into the Great Depression. The Dow Jones Industrial Average, which had peaked at 381.17 on 3 September 1929, would fall, over the next three years, to 41.22 on 8 July 1932, a loss of about 89 percent. It is the defining financial crash of the twentieth century and the event against which every later panic is measured.
The mania that preceded it ran on borrowed money. Through the 1920s, ordinary Americans were drawn into the stock market in unprecedented numbers, and many bought “on margin” — putting down a fraction of a stock’s price and borrowing the rest from a broker, who in turn borrowed from banks. By the summer of 1929 these brokers’ loans exceeded 8.5 billion dollars, more than the entire stock of currency then circulating in the country. Margin let a small rise in a share produce a large gain on the cash invested; it also meant a small fall could wipe a buyer out entirely and force the sale of his stock to repay the loan.
That structure made the market exquisitely fragile. When prices began to slide in September and then plunged in late October, falling values triggered “margin calls” — demands that borrowers post more cash — and buyers who could not pay had their holdings dumped onto a falling market, which drove prices lower still and triggered further calls. On Black Tuesday, 29 October, some 16.4 million shares changed hands in a cascade of forced and panicked selling. A pool of leading bankers had tried to halt the slide the week before by ostentatiously buying shares, and for a day it worked; within days it failed utterly.
The crash did not single-handedly cause the Depression, but it destroyed savings, shattered confidence, and accelerated a collapse that would see thousands of banks fail and unemployment reach roughly a quarter of the workforce. Out of the wreckage came a generation of reform — the Pecora investigation, the Glass-Steagall separation of commercial and investment banking, and the creation of the Securities and Exchange Commission — built on the recognition that a market financed by debt and faith in permanent prosperity had been a disaster waiting for its trigger.
In the United States between roughly 1995 and 2000, a speculative mania for internet stocks drove the technology-heavy Nasdaq Composite index to a peak of 5,048.62 on 10 March 2000, after which it collapsed, falling about 78 percent to a low near 1,114 by October 2002 and erasing on the order of 5 trillion dollars in market value. The dot-com bubble is the defining financial mania of the internet age: a frenzy in which companies with no profits, and often no plausible path to them, were valued at billions on the strength of a story about the future.
The mania ran on a new and corrosive idea about value. As a genuinely transformative technology arrived, investors and entrepreneurs persuaded themselves that the old measures — revenue, earnings, the price-to-earnings ratio — no longer applied to internet companies, and that growth in users, page views, and “eyeballs” was the metric that mattered. A start-up’s strategy became “get big fast”: raise enormous sums, spend them at a furious “burn rate” on marketing and expansion to capture a market, and trust that profits would somehow follow scale. By the peak, the great majority of newly public technology companies were losing money, yet were valued as if dominance were already theirs.
The plumbing of the boom was the initial public offering. Underwriters and a credulous market rewarded internet start-ups with spectacular first-day stock “pops,” so that founders, venture capitalists, and early employees grew rich the moment a company went public, regardless of whether it ever earned a cent. That rewarded raising and spending money over making it, and it pulled ordinary investors — newly armed with online brokerage accounts and a financial media that treated tech founders as visionaries — into buying at any price, certain a greater fool stood behind them.
The break came in the spring of 2000. The Federal Reserve had been raising interest rates, making the cheap capital that fed the burn rates costlier, and a market that had run on belief began to question it. The Nasdaq peaked on 10 March, slid, and then plunged through April; over the following two years the unprofitable companies ran out of money and failed in waves — Pets.com, Webvan, eToys, Boo.com, and hundreds more. The technology was real and would remake the world, and a handful of survivors, Amazon and eBay among them, justified the early faith. The prices, for almost everyone else, did not.
In the United States between roughly 2000 and 2006, the price of the typical American house nearly doubled, propelled by an almost universal conviction — held by borrowers, lenders, rating agencies, regulators, and the largest banks on Wall Street — that house prices could not fall nationwide. That conviction collapsed in 2007–2008. The S&P/Case-Shiller national home price index, which peaked in the first quarter of 2006 at about 198, fell to roughly 114 by early 2012, a decline of more than 40 percent from peak to trough, and the financial machinery built on the assumption of ever-rising prices failed catastrophically.
The delusion was not chiefly about flowers or tulips but about correlation. Lenders extended mortgages to borrowers who could not plausibly repay them — the subprime loans that grew from about 5 percent of originations in the mid-1990s to roughly 20 percent, around $600 billion, by 2006 — because the loans were not meant to be repaid so much as refinanced or sold. Wall Street pooled those mortgages into securities and sliced them into tranches, and the rating agencies blessed the senior pieces as nearly riskless on the statistical premise that home prices in different regions would not all fall at once. They did all fall at once.
When prices turned in 2006 and defaults rose, the chain ran in reverse. In 2007 two Bear Stearns hedge funds invested in mortgage securities imploded; through 2008 the losses spread until the investment bank Lehman Brothers filed for bankruptcy on 15 September 2008, the largest such filing in US history, and the global financial system seized. US household net worth fell by an estimated $13 trillion; foreclosure filings surpassed 3 million in 2008 alone; and the recession cost roughly 9 million jobs. The episode proved a mania need not be confined to amateurs: the most sophisticated institutions in the world, armed with risk models and credit ratings, talked themselves into the same single error — that the thing going up would keep going up — and built a global edifice of leverage on top of it.
In Japan during the late 1980s, the prices of stocks and especially land rose to heights that briefly made the country, on paper, the richest place that had ever existed. The Nikkei 225 stock average reached an all-time high of 38,957.44 on 29 December 1989, and Tokyo land grew so dear that the grounds of the Imperial Palace — about 1.15 square kilometers — were estimated to be worth more than all the real estate in the state of California. By the end of 1990 the Nikkei had lost nearly half its value, and over the following decade urban land prices fell by more than 80 percent. The collapse opened what became known as Japan’s “Lost Decades.”
The bubble was not built on a novel asset or amateur speculation but on the bedrock belief of an entire society: that Japanese land never fell in price. In a small, densely populated, fast-growing country, that “land myth” had held for the whole postwar era, and it became the unquestioned collateral on which the banking system rested. Banks lent freely against real estate whose value, everyone agreed, could only rise; companies borrowed against their soaring shares to buy more shares and more land; and a dense web of cross-shareholdings among corporations and their banks meant the whole structure rose and fell together.
The fuel was cheap money. Following the 1985 Plaza Accord, which sharply raised the yen and threatened Japanese exports, the Bank of Japan cut its discount rate to a then-record 2.5 percent and held it there, flooding the economy with credit that surged into stocks and land rather than goods. When a new central bank governor, Yasushi Mieno, set out to crush the speculation and raised rates from 2.5 percent in 1989 to 6 percent by August 1990, the edifice cracked: the Nikkei fell from about 38,915 at the end of 1989 to around 21,900 a year later. The bursting left banks crippled by bad loans, companies and households paying down debt for years, and an economy barely larger two decades on than before — the case that taught the world the phrase “Lost Decade,” and then forced the plural.
In the United States during the late 1990s, millions of ordinary people came to believe that small bean-filled plush toys, sold for about $5 each, were a serious investment that would fund college tuitions and retirements. At the craze’s height a single “retired” Beanie Baby in mint condition with its paper tag could fetch hundreds or even thousands of dollars on the resale market — rare examples were quoted as high as $13,000 — and a 1998 USA Weekend poll found that roughly 64 percent of Americans owned at least one. Around 1999 the resale market collapsed, and the vast majority of those collections became close to worthless.
The Beanie Baby bubble is the purest modern example of a mania built on manufactured scarcity rather than any real underlying value. The toys were mass-produced by the millions in overseas factories; what made particular ones “rare” was a deliberate strategy by their maker, Ty Warner of Ty Inc. He sold only to small specialty shops, never the big chains, and capped how many of each design a store could order. Beginning in 1995 he periodically “retired” designs, halting production to create the impression that the existing supply was finite and therefore precious. None of this scarcity was natural; all of it was engineered.
The new medium of eBay turned that engineered scarcity into a speculative market. The online auction site let buyers and sellers across the country trade individual toys and watch prices in real time; by 1997 Beanie Babies reportedly accounted for around $500 million in eBay sales, a substantial share of the young company’s business. People tracked “values,” bought multiples to hold as investments, and treated a child’s toy as an appreciating asset, while Ty Inc.’s sales surged past $1 billion and reportedly toward $1.4 billion by 1998. The craze ended not in financial catastrophe but in quiet, widespread loss: when Ty announced in 1999 that it would retire the entire line, the expected surge in value never came; collectors who had hoarded the toys flooded eBay, the manufactured scarcity reversed into a glut, and prices fell by some 90 percent or more. The episode is a clean demonstration of how a delusion of value can be conjured from nothing but the suggestion of rarity and the expectation that someone else will pay more.
Between 1973 and early 1980, the Texas oil heirs Nelson Bunker Hunt and William Herbert Hunt — with their younger brother Lamar and a group of Saudi partners — accumulated an extraordinary hoard of silver and silver futures, driving the metal from around $6 an ounce to a record $49.45 on 18 January 1980 before the position collapsed in the spring. The unwinding climaxed on Thursday, 27 March 1980 — “Silver Thursday” — when the price fell from $21.62 to $10.80 in a single day, leaving the brothers unable to meet a margin call estimated at $100 million and facing some $1.7 billion in losses.
The episode was not a faceless market mania like Tulip Mania or the South Sea Bubble but a deliberate attempt by two of the richest men in the world to corner a global commodity. By late 1979 the Hunts and their associates controlled an estimated 100 million ounces of silver and large futures positions — by some estimates a third of the world’s privately held supply, or roughly 70 percent of deliverable stocks. As prices soared, ordinary speculators piled in behind them and households melted heirlooms to sell, so that a private gamble became a public frenzy. The delusion was the belief that wealth and conviction could hold a corner indefinitely against the exchanges, the regulators, and the arithmetic of leverage.
The corner broke when the rules changed. In January 1980 the commodity exchanges, alarmed by the runaway market, imposed emergency limits — COMEX’s “Silver Rule 7” restricted buying on margin and the exchanges moved positions toward liquidation only. With new buying choked off, the price stalled, then reversed, and the Hunts’ heavily borrowed position turned against them with brutal speed. A consortium of banks arranged a $1.1 billion rescue loan to prevent a cascade of failures across Wall Street brokerages.
The aftermath was ruinous and slow. The Hunts spent the 1980s in litigation; in August 1988 a federal jury found them liable for conspiring to manipulate the silver market, awarding some $134 million to the Peruvian minerals firm Minpeco, and weeks later Nelson Bunker Hunt filed for bankruptcy. The case stands as the modern textbook example of a cornered commodity: a study in how leverage, concentration, and the conviction of very rich men collide with the limits of a market that can always change its rules.
In late 1969 and early 1970, shares in the small Australian exploration company Poseidon NL rose from around 80 cents to an intraday peak of roughly $280 — a gain of some 350-fold in a few months — after the firm announced a nickel discovery at Mount Windarra in Western Australia, before collapsing through 1970 in a crash that swept the whole Australian mining sector. The Poseidon bubble remains the defining speculative episode in Australian market history: a penny stock that became a national obsession and then a cautionary tale.
The trigger was real. In September 1969 Poseidon did strike nickel near Laverton, and on 1 October the company announced an early drilling result of about 40 metres averaging 3.56 percent nickel — a genuinely promising intercept at a moment when nickel was scarce and expensive. A miners’ strike against the dominant Canadian producer, Inco, and demand linked to the Vietnam War had pushed nickel to record prices, peaking around £7,000 a ton in London in November 1969. Into that backdrop a small company with a fresh strike was perfectly placed to become a sensation, and it did: the share price trebled before the assays were even confirmed, then ran on rumour and a now-notorious broker’s circular suggesting the shares might be worth $382.
What followed was a textbook mania. As Poseidon soared, dozens of other explorers floated or renamed themselves to ride the nickel theme, and ordinary Australians — many investing in shares for the first time — poured into “penny dreadful” mining stocks on the strength of names, maps, and tips. The deluge of new money chased ground that had barely been drilled, and the valuations bore no relation to any proven ore. The whole sector peaked early in 1970 and then collapsed, erasing billions and ruining countless small investors who had bought near the top.
Poseidon’s own end was prosaic. The Windarra ore proved lower-grade and costlier to extract than the frenzy had assumed; the nickel price fell back; the mine never returned a profit, and the company entered receivership in 1974 and was delisted in 1976. The bubble prompted a landmark Senate inquiry under Senator Peter Rae, which found the conduct of directors and geologists “evasive, distorted, exaggerated and simply untrue” in important respects, and helped drive the modern reform of Australian securities regulation. The case endures as the archetype of the mining-promotion bubble.
Between 1993 and 1997, the small Canadian exploration company Bre-X Minerals told the world it had found one of the largest gold deposits in history at Busang, deep in the jungle of East Kalimantan, Indonesia — a claim that drove its market value above C$6 billion before independent testing in 1997 revealed that the core samples had been deliberately salted with gold and that there was, in the end, essentially no gold at all. It was one of the largest mining frauds ever exposed, and it ruined tens of thousands of investors.
The fraud’s mechanics were crude and, for a long time, undetected. Bre-X’s drill cores were tampered with — gold dust, much of it placer gold panned from rivers, was sprinkled into crushed samples before assay — so that the laboratory results showed a steadily growing, spectacular gold grade. On the strength of those results the reported resource swelled from about 2 million ounces in 1995 to 30 million, then 60 million, then 70 million by 1997, with company figures suggesting a potential of 200 million ounces. Bre-X shares, which had traded for pennies, rose to a split-adjusted peak above C$280 on the Toronto Stock Exchange, and the company was hailed as the find of the century.
The collapse was triggered by due diligence. As the American mining giant Freeport-McMoRan conducted its own drilling in early 1997 as part of a deal to develop Busang, it found only insignificant traces of gold, and an independent review by Strathcona Mineral Services concluded in May 1997 that the Bre-X samples had been falsified — that the deposit, as described, did not exist. The shares, which had once made paper fortunes, fell to pennies and the company filed for bankruptcy protection.
The human cost was severe and, in one case, fatal. On 19 March 1997, as scrutiny of Busang intensified, Bre-X’s chief geologist, Michael de Guzman, died after falling from a helicopter over the Borneo jungle; his death was officially ruled a suicide, though it remains the subject of dispute. Some 40,000 investors, including major pension funds, lost their money. No one was ever criminally convicted of the fraud in Canada. The case reshaped mining-disclosure rules and stands as the definitive warning about salted samples, unverified assays, and a market’s hunger to believe in the find of a lifetime.
In late January 2021, shares of GameStop — a struggling American video-game retailer that began the month near $17 — spiked to an intraday high of $483 on 28 January before collapsing by roughly ninety percent within weeks. The surge was organized largely on the Reddit forum r/wallstreetbets, where retail traders had spotted that hedge funds had sold short more shares than the company even had freely trading, and set out to force those bets into ruinous reverse. For a few days the plan worked spectacularly; then the price came down almost as fast as it had gone up.
The episode was two things at once, and the confusion between them is the heart of the case. It was a genuine short squeeze with real market mechanics: with short interest reported at roughly 140 percent of the public float, every dollar the price rose forced bearish funds to buy shares to limit their losses, which pushed the price higher still. Melvin Capital, one of the largest shorts, lost so heavily that it took a $2.75 billion cash infusion — $2 billion from Citadel and $750 million from Point72 — on 25 January, and shut down entirely the following year. But the squeeze was also a social-media euphoria in which a far larger crowd, drawn by viral posts, defiance of Wall Street, and the dream of life-changing gains, bought a near-worthless business at a price no fundamental analysis could justify.
The two stories had different endings. The squeeze itself was a finite, mechanical event: once the trapped shorts had mostly covered, the engine that drove the rocket was spent. The euphoria lasted longer and cost more, because the people who arrived late — many buying on 27 and 28 January at prices above $300 — were not squeezing anyone. They were the greater fools of a classic bubble, holding an asset whose price depended entirely on the next buyer paying more. When the brokerage Robinhood and others abruptly restricted buying on 28 January, the inflow stalled, and the price fell from $483 toward $40 over the following weeks.
The aftermath reshaped both regulation and folklore. A congressional hearing in February 2021 put a Reddit trader, a Citadel founder, and Robinhood’s chief executive at the same virtual table. An SEC staff report that October concluded, contentiously, that sustained positive sentiment rather than the buying-to-cover of trapped shorts kept the price elevated for weeks — a finding that, if correct, makes the later phase less a squeeze than a self-reinforcing crowd. Either way, GameStop became the founding myth of the “meme stock,” a template for collective speculation that has recurred since.
In Britain in 1896, the share prices of cycle-manufacturing companies almost trebled in a few months — an index of the sector rising from about 88 in January to 250 by May — before sliding back and then collapsing, losing roughly 73 percent of its peak value by the end of 1898. The British Bicycle Mania was a textbook technology bubble: a genuinely transformative new product, a flood of company flotations to exploit it, a burst of speculative euphoria, and a long, grinding collapse in which most of the companies and much of the public’s money disappeared.
The underlying enthusiasm was not foolish. The 1890s “safety” bicycle, with two equal wheels, a chain drive, and John Boyd Dunlop’s pneumatic tyre, was a real revolution — affordable, practical mass mobility that swept Britain’s middle and upper classes into a cycling craze. The error lay in the leap from “bicycles are the future” to “any bicycle-company share must rise.” Between January 1896 and June 1897 some 601 new cycle corporations were floated, many promoted at valuations that bore no relation to the modest profits a competitive manufacturing business could ever earn.
The boom had its catalysts and its profiteers. In April 1896 two events lit the fuse: the Pneumatic Tyre Company was bought for £3 million and refloated as the Dunlop Pneumatic Tyre Company for £5 million by the promoter Ernest Terah Hooley, and the Beeston Pneumatic Tyre Company declared a 100 percent dividend. Trading on the Birmingham Stock Exchange, the heart of the cycle trade, was said to have “gone mad.” Promoters like Hooley grew briefly rich floating companies to a credulous public — then went spectacularly bankrupt themselves, Hooley in 1898.
The collapse, when it came, was driven by ordinary economics. The market for bicycles saturated, a wave of cheaper American machines undercut British makers, and the profits needed to justify the share prices never materialized. Modern research by the economic historians William Quinn and John Turner adds a sharper lesson: the people who lost most were not naive first-timers but confident “gentlemen” living near stock exchanges, while company directors and employees, who knew the businesses best, quietly sold out before the fall.
