Wall Street Scandals
Almost every rule on Wall Street was written after someone broke it. This exhibit collects the most infamous frauds and failures in market history — the Ponzi schemes, the accounting blow-ups, the single traders who sank centuries-old banks — each with the verified figure behind the headline.

Bernie Madoff’s clients believed they held about $65 billion — the number printed on their statements. Almost none of it was real: he ran the largest Ponzi scheme in history, and in 2009 was sentenced to 150 years in prison.
The Ponzi scheme is named for Charles Ponzi, who in 1920 promised investors a 50% profit in 45 days by trading international postal reply coupons. He was really paying earlier investors with later investors’ money — the same mechanism every Ponzi has used since.
When Enron collapsed into bankruptcy in December 2001, it took its auditor down with it: Arthur Andersen, one of the world’s five largest accounting firms, was convicted of obstruction and effectively ceased to exist — even though the Supreme Court later overturned the conviction.
WorldCom inflated its profits by roughly $11 billion by booking ordinary expenses as long-term investments — the largest accounting fraud in U.S. history at the time. Its 2002 collapse helped push Congress to pass the Sarbanes-Oxley Act; CEO Bernard Ebbers was sentenced to 25 years.
A single trader, Nick Leeson, hid £827 million in losses and destroyed Barings — Britain’s oldest merchant bank, founded in 1762. After the 1995 collapse, the 233-year-old institution was sold to ING for one pound.
For a few days in October 2008, Volkswagen was the most valuable company in the world. Porsche had quietly cornered the stock — controlling about 74% through shares and options — and when short sellers scrambled to cover with almost no float left, VW briefly spiked to around €1,005 a share.
In January 2021, retail traders organizing on Reddit turned GameStop into the ultimate short squeeze. More than 140% of the stock’s float had been sold short; as the crowd bought, the price ran from under $20 to an intraday high of $483, and hedge fund Melvin Capital needed a $2.75 billion rescue after its bet against the stock collapsed.
Michael Milken built the junk-bond market of the 1980s, then pleaded guilty in 1990 to securities and tax felonies and paid $600 million in fines. He was banned from the securities industry for life — and pardoned by President Trump in 2020.
In 2000 the SEC charged Jonathan Lebed, a 15-year-old from New Jersey, with stock manipulation — the first minor it had ever gone after. From his bedroom he bought thinly traded stocks, hyped them with repeated posts on message boards, and sold into the spike; he settled by giving back $285,000 and was allowed to keep the rest.
Arbitrageur Ivan Boesky paid a $100 million penalty in 1986 for insider trading — the largest ever at the time. Months earlier he had told a graduating class that “greed is healthy,” the line that inspired Gordon Gekko’s “greed is good.”
Long-Term Capital Management had two Nobel Prize-winning economists among its partners and still nearly brought down the financial system. When it blew up in 1998, the Federal Reserve organized a $3.6 billion rescue by 14 banks to unwind it without a panic.
In 2008 a single Société Générale trader, Jérôme Kerviel, ran up €4.9 billion in losses on unauthorized positions — the largest rogue-trader loss on record at the time. A court later slashed the damages he personally owed, faulting the bank’s own risk controls.
Tyco’s CEO Dennis Kozlowski was convicted in 2005 of looting more than $600 million from the company. The spending that made him infamous: a $6,000 shower curtain and a $2 million birthday party in Sardinia, half of it billed to Tyco.
Wirecard was a member of Germany’s blue-chip DAX index when it admitted in 2020 that €1.9 billion of cash on its books simply did not exist. The company collapsed within days, and its chief operating officer fled and remains a fugitive.
Bre-X claimed to have found one of the largest gold deposits ever, deep in the Indonesian jungle, and was briefly worth about $6 billion. The core samples had been salted with gold dust; as the fraud unraveled in 1997, the project’s chief geologist fell to his death from a helicopter.
On a single morning in 2012, a botched software update caused Knight Capital’s systems to fire millions of unintended orders into the market. The firm lost about $440 million in roughly 45 minutes — nearly wiping out one of the largest traders in U.S. stocks.
Crazy Eddie was a New York electronics chain famous for its “his prices are insane” ads, and one of the era’s boldest accounting frauds. After going public in 1984, the Antar family inflated inventory to prop up the stock and cashed out more than $90 million before the company collapsed into bankruptcy in 1989.
Through the summer of 2020, big-tech stocks kept ripping higher and few could say why — until the Financial Times unmasked the “Nasdaq whale.” SoftBank had reportedly bought about $4 billion of call options on tech stocks, a bet with reported notional exposure near $30 billion.
Allen Stanford sold billions in certificates of deposit promising safe, above-market returns — all backed by a $7 billion Ponzi scheme. In 2012 he was sentenced to 110 years in prison.
Barry Minkow took his carpet-cleaning company ZZZZ Best public at age 21, one of the youngest founders ever to do so. Most of the business was fictional — a fake insurance-restoration division — and it collapsed in 1987, costing investors and lenders around $100 million.
