Sam Bankman-Fried and the Collapse of FTX

Abstract

For two years Sam Bankman-Fried was the acceptable face of cryptocurrency, a rumpled, T-shirted MIT physics graduate who ran the world’s second-largest crypto exchange, FTX, preached “effective altruism,” gave millions to politicians of both parties, and was photographed with presidents and quarterbacks. In November 2022 the entire edifice collapsed in under a week when it emerged that FTX had been quietly funneling roughly $8 billion of customers’ deposits to his private trading firm, Alameda Research, to cover its losses and bets. The bank run that followed bankrupted FTX, vaporized customer funds, and exposed crypto’s most celebrated company as an old-fashioned fraud. In November 2023 a Manhattan jury convicted him on all seven counts; in March 2024 he was sentenced to 25 years in federal prison and ordered to forfeit $11 billion. His story is the defining financial scandal of the crypto era, proof that the industry’s promise of trustless, transparent money had, at its center, the oldest trust problem of all.

The Effective Altruist

Sam Bankman-Fried was born on March 5, 1992, on the Stanford campus to two law professors, and graduated from MIT in 2014 with a degree in physics. He went to the quantitative trading firm Jane Street Capital, then left to apply Wall Street’s arbitrage techniques to the wildly inefficient cryptocurrency markets. His stated motive was philosophical: he was a devotee of effective altruism, the movement that holds one should earn as much money as possible in order to give it away to maximize good. “Earning to give” became his public identity and his moral cover.

In November 2017 he co-founded Alameda Research, a crypto trading firm, and in April 2019 he launched FTX, a cryptocurrency exchange where customers could trade and store digital assets. FTX grew explosively. By 2021 Bankman-Fried was on the Forbes 400 as one of the richest people in America, FTX had bought naming rights to a Miami arena, and “SBF” had become the industry’s lobbyist-in-chief, courting regulators in Washington with the message that he was the responsible adult in a reckless business.

The Conflict at the Core

The fatal flaw was the relationship between the two companies. FTX was an exchange, a custodian that was supposed to hold customer deposits safely, the way a bank or a brokerage does. Alameda was a hedge fund that made risky, leveraged bets. They were supposed to be at arm’s length. They were not.

What “Commingling” Means

An exchange’s one inviolable rule is that customer money is customer money, held in trust, never spent. FTX broke that rule. Through a secret arrangement, FTX routed customer deposits to Alameda, which used them as its own trading capital and collateral, and exempted Alameda from the automatic risk controls that governed every other FTX account. When Alameda’s bets went bad, it was already deep in customers’ funds. There was no clever crypto innovation here and no “hack”, the technology worked fine. It was embezzlement, distinguished from the 20th-century kind only by being denominated in tokens.

One Week in November

The collapse was triggered by a leak. In early November 2022, the crypto news site CoinDesk published a report showing that the bulk of Alameda’s assets consisted of FTT, the token FTX had itself created, meaning Alameda’s solvency rested on a coin its sister company minted. The disclosure spooked the market.

  • November 6–7: Changpeng Zhao, CEO of the rival exchange Binance, announced he would sell Binance’s large holdings of FTT.
  • November 8: As FTT’s price cratered and customers rushed to withdraw, FTX faced a liquidity crisis it could not meet, because the money was gone. Binance briefly signed a non-binding agreement to acquire FTX.
  • November 9: Binance walked away after a look at the books. FTT lost roughly 80% of its value.
  • November 11: FTX, Alameda Research, and more than 130 affiliated entities filed for bankruptcy. Bankman-Fried resigned as CEO.

A run on a bank that had spent its depositors’ money ended the way such runs always end. Customers around the world found their balances frozen and, in many cases, gone. The restructuring team that took over (led by the lawyer who had wound down Enron) described internal controls as nonexistent.

Trial and Sentence

Bankman-Fried was arrested in Nassau, the Bahamas, on December 12, 2022, and extradited to the United States. Two of his closest lieutenants, Caroline Ellison (Alameda’s CEO and his sometime girlfriend) and FTX co-founder Gary Wang, pleaded guilty and testified against him. His trial in Manhattan ran through October 2023, and on November 2, 2023, the jury convicted him on all seven counts, including wire fraud, securities fraud, and money laundering conspiracy. On March 28, 2024, Judge Lewis Kaplan sentenced him to 25 years in prison and ordered the forfeiture of about $11 billion.

In a twist that complicated the morality play, the bankruptcy estate ultimately recovered enough assets (boosted by a recovery in crypto and tech prices) to repay creditors most or all of their claims at the dollar value as of the bankruptcy date, though not the far larger sums those assets would have been worth had they never been frozen.

Dead End: “Effective Altruism” as Alibi

Bankman-Fried’s significance to computing history is partly technological and partly cultural. FTX was, briefly, critical infrastructure for an entire asset class; its failure froze the industry, wiped out competitors, and invited the regulatory crackdown that SBF had spent years lobbying to soften. But the deeper lesson is about the ideology he wore.

Effective altruism (and the broader “build fast, the ends justify the means” ethos of the tech and crypto worlds) gave Bankman-Fried a vocabulary in which fraud could be reframed as utilitarian calculation: if you are going to give the money to save the world, the rules protecting customers become a rounding error against the greater good. The collapse discredited that reasoning by demonstrating where it leads. It also punctured crypto’s founding claim. Bitcoin and its successors were sold as trustless systems that removed the need for fallible human intermediaries; FTX showed that the moment ordinary people used crypto in practice, they did it through a centralized custodian they had to trust completely, and that the custodian could rob them as easily as any bank ever could, with less oversight.

Like the other figures on this page, Bankman-Fried is documented on the principle of impact, not endorsement: he changed crypto’s trajectory, its regulation, and its public image, and he did it by committing one of the largest financial frauds in American history. Naming it as fraud, plainly, matters more than parsing the philosophy he used to dress it up.
