Top 10 Biggest Fortunes Lost in History — Billions Gone and the Shocking Stories Behind Them

Sam Bankman-Fried went from a Forbes-estimated $26 billion net worth in October 2022 to zero — and facing federal fraud charges — in November 2022, after his FTX cryptocurrency exchange collapsed, revealing a $8 billion hole in customer funds. SBF had been on the cover of Forbes and Fortune, had given $40 million to political campaigns, and was considered the most legitimate figure in cryptocurrency. The FTX collapse evaporated $32 billion in customer and investor funds. He was convicted on all seven counts of fraud and conspiracy and sentenced to 25 years in federal prison in March 2024.

Elizabeth Holmes built Theranos to a $9 billion valuation on a fraudulent claim: that its Edison machine could perform 200+ medical tests from a single drop of blood. None of it was true. The company secretly used conventional machines for most tests while telling investors, patients, and regulators otherwise. Holmes raised $945 million from investors including Rupert Murdoch, Betsy DeVos, and the Walton family before journalist John Carreyrou's Wall Street Journal investigation exposed the fraud in 2015. Holmes was convicted of four counts of investor fraud in 2022 and sentenced to 11 years in federal prison.

Adam Neumann convinced SoftBank that WeWork, a commercial real estate company with a yoga-and-kombucha aesthetic, was a technology company worth $47 billion. The 2019 IPO prospectus, which referred to the company's "energy" and Neumann's "superpower of making people feel," was widely mocked. The IPO was pulled; within months WeWork's valuation had collapsed to $5 billion. SoftBank wrote off $9.5 billion in losses. WeWork filed for bankruptcy in November 2023. Neumann personally received $1.7 billion in exit payments from SoftBank — making him unusual among catastrophic business failures as someone who profited from the destruction.

In 2012, Eike Batista was worth $34.5 billion — Brazil's richest man and the 7th wealthiest person on Earth. He had publicly promised to become the world's richest man by 2015. His empire of mining, oil, port, and logistics companies (OGX, LLX, MMX, MPX) was almost entirely leveraged on oil field estimates that turned out to be 90% smaller than advertised. By 2014, he owed $1.1 billion more than he owned — a swing of $35 billion in 18 months. He was later arrested on corruption charges related to bribing government officials, convicted, and sentenced to 30 years in Brazilian prison.

The Mercer family invested heavily in Cambridge Analytica, the data analytics firm at the center of the Facebook data misuse scandal that began unraveling in 2018. Cambridge Analytica harvested the data of 87 million Facebook users without consent, used it to target political advertising, and was connected to both Brexit and the 2016 Trump campaign. The resulting scandal cost Facebook $5 billion in FTC fines and wiped $134 billion from its market cap in a single day — and shut down Cambridge Analytica entirely. The full financial losses to investors who had backed the firm and its parent SCL Group remain undisclosed.

In January 2023, U.S. short-seller Hindenburg Research published a 106-page report alleging that Gautam Adani's conglomerate had engaged in "brazen stock manipulation and accounting fraud" over decades. Adani's response — pulling a $2.5 billion share offering and releasing a 413-page rebuttal — failed to stop the rout. Adani Group stocks lost $120 billion in market value in three trading days, wiping out virtually all of Gautam Adani's gains from his rapid climb to the top five of the world's richest people. Adani subsequently recovered substantially, but the episode demonstrated the devastation a credible short-seller report can inflict on concentrated conglomerates.

In May 2022, Terraform Labs' algorithmic stablecoin TerraUSD (UST) lost its dollar peg, triggering a death spiral that wiped out $40 billion in value in 72 hours — one of the fastest wealth destructions in financial history. Terra's sister token LUNA fell from $80 to $0.0002. Millions of retail investors globally lost their life savings. Do Kwon, who had publicly mocked critics who warned the mechanism was flawed ("I don't debate the poor"), fled South Korea and was arrested in Montenegro in 2023. He was extradited to the United States in 2024 and faces multiple fraud charges.

News Corporation's phone-hacking scandal, which emerged fully in 2011 with revelations that News of the World journalists had hacked the voicemail of murdered teenager Milly Dowler, triggered the closure of the 168-year-old newspaper, a £1 billion corporate settlement, and destroyed Murdoch's bid to acquire full control of BSkyB. Parliamentary hearings created the most sustained reputational assault on any media baron since William Randolph Hearst. Murdoch's sons were implicated; executives were imprisoned; the political relationships that had made Murdoch's British operations so powerful were permanently severed. The total cost, including civil settlements, exceeded $1.5 billion.

Meta's 2022 market cap collapse, triggered by the combination of Apple's ATT privacy changes (which cost Meta $10 billion in ad revenue) and Zuckerberg's $35 billion metaverse bet that the market dismissed as delusional, saw the company lose $700 billion in market cap — the largest single-year market cap destruction in the history of any single company. Zuckerberg personally lost $100 billion in paper wealth, dropping from the world's 4th to 20th richest person. His 2023 "Year of Efficiency" recovery — cutting 21,000 jobs and refocusing on AI — is one of the greatest corporate reversals in history. By 2024 he had recovered all the losses and more.
