Sam Bankman-Fried — the exchange that spent its customers’ deposits
Summary
In New York, on November 2, 2023, a federal jury convicted the founder of the cryptocurrency exchange FTX of one of the largest financial frauds of the decade. Samuel Bankman-Fried had built FTX into the world's second- or third-largest crypto exchange while secretly directing that its customers' deposits be funneled to Alameda Research, the affiliated trading firm he owned, where the money was used for venture investments, loan repayments, political donations, real estate, and the firm's own losing bets. When customers tried to withdraw in November 2022, roughly $8 billion that should have been theirs was not there.
The verdict was complete. After a four-week trial in the U.S. District Court for the Southern District of New York, the jury deliberated for roughly five hours and found Bankman-Fried guilty on all seven counts: two of wire fraud, two of conspiracy to commit wire fraud, and one each of conspiracy to commit securities fraud, conspiracy to commit commodities fraud, and conspiracy to commit money laundering. On March 28, 2024, Judge Lewis A. Kaplan sentenced him to 25 years in federal prison and ordered forfeiture of approximately $11 billion.
The numbers were contested only at the margins. At sentencing, Judge Kaplan found losses of roughly $8 billion to FTX customers, $1.7 billion to FTX investors, and $1.3 billion to lenders to Alameda Research, and he rejected the defense's claim that customers would suffer no real loss as "misleading" and "logically flawed." FTX had filed for bankruptcy on November 11, 2022, listing more than 130 affiliated entities; the case against its founder was assembled from internal records and the testimony of his closest deputies, three of whom pleaded guilty and cooperated.
What distinguished the FTX collapse was the gap between its presentation and its plumbing. FTX marketed itself as a safe, well-regulated venue and told users their deposits were theirs, held one-to-one. Underneath, the exchange's software contained features that exempted Alameda from the risk controls applied to everyone else and allowed it to draw effectively without limit on customer funds. The fraud was not an exotic financial instrument; it was the oldest breach in finance, spending money held in trust, executed through code and concealed by the aura of a fast-growing technology company.
Timeline
A Reputation Engineered for Trust
Bankman-Fried's defense against scrutiny was an image, and the image was deliberate. He presented as a rumpled, idealistic technologist who slept on a beanbag, drove a modest car, and intended to give his fortune away under the banner of "effective altruism." He cultivated regulators and lawmakers, testified before Congress on crypto policy, donated heavily to political campaigns, and positioned FTX as the responsible, compliant face of a chaotic industry. The persona functioned exactly as institutional respectability had for older frauds: it answered the question of trustworthiness before anyone could ask it.
That trust translated into capital and customers. Blue-chip venture firms invested in FTX at valuations that reached $32 billion, and their participation served as a credential that users read as validation. Celebrity endorsements and stadium naming rights extended the reach. Each external marker of legitimacy substituted for the kind of verification that would have asked the only question that mattered: where, precisely, were the customer deposits, and could anyone other than the founder confirm they were untouched.
The structure beneath the image was opaque by design. FTX and Alameda were presented to the public as separate, arm's-length entities, an exchange and one of its trading customers, when in fact both were controlled by Bankman-Fried and bound together by software and money flows hidden from users. The separation that would have protected customers, an exchange that merely holds and matches, taking no proprietary risk with deposits, existed in the marketing and not in the code. The persona made the opacity feel safe.
The Code That Moved the Money
An exchange is supposed to be a custodian: it holds customer assets and matches their trades, but it does not lend or spend those assets for its own account. FTX violated that premise at the level of its software. The exchange's risk engine automatically liquidated any account whose collateral fell short, which is what protects all users from any one user's losses. Alameda was exempted from that engine. A specific code privilege allowed Alameda to carry an effectively unlimited negative balance, meaning it could pull customer funds out of FTX without triggering the liquidation that constrained everyone else.
That single exemption converted a custodian into a lender to its own affiliate. Customer deposits flowed to Alameda, which used them as working capital for trading, for venture investments in other companies, for repaying loans from crypto lenders, for buying real estate in the Bahamas, and for political and personal spending. None of this was disclosed to the customers whose money it was, and FTX's public assurances, that user funds were held and not invested, were false. The fraud's mechanism was not a complex derivative; it was a back-office permission that quietly removed the wall between deposits and spending.
The structure was self-reinforcing while markets rose and self-destroying when they fell. Much of the collateral propping up the arrangement was FTX's own token, FTT, an asset FTX itself created. Counting FTT at market value made Alameda and FTX look solvent, but FTT had no independent backing and would collapse the moment confidence wavered. When the 2022 crypto downturn battered Alameda's other holdings, the hole in customer funds widened, and the firms leaned harder on the deposits that were never theirs to use. The accounting that hid the gap depended on a price that the fraud itself could not sustain.
The Run That Emptied the Account
The trigger, as in every scheme that spends money held in trust, was a demand for the money. In early November 2022, a published look at Alameda's balance sheet revealed how dependent it was on FTT, and a rival exchange announced it would liquidate its own FTT holdings. Confidence evaporated within days. FTX customers, told for years that their deposits were safe and withdrawable, moved to withdraw billions at once. A genuine custodian holding assets one-to-one could have met them. FTX could not, because the assets had been transferred to Alameda and spent.
The gap was not a temporary liquidity squeeze but an absence. Roughly $8 billion that customers believed was theirs did not exist in withdrawable form. On November 11, 2022, FTX and more than 130 related entities filed for bankruptcy, and Bankman-Fried resigned in favor of John J. Ray III, the restructuring expert who had overseen the Enron wind-down. Ray's early filings described a near-total failure of corporate controls, an absence of reliable records, and a commingling of funds that he characterized as among the worst he had encountered.
The legal reckoning was rapid because the witnesses were insiders. Caroline Ellison, the chief executive of Alameda, Gary Wang, FTX's co-founder and chief technology officer, and Nishad Singh, its head of engineering, each pleaded guilty and testified that Bankman-Fried directed the use of customer funds and the special treatment of Alameda. Their accounts, corroborated by the code and the records, left the defense little room. The jury convicted on every count in November 2023, and the sentence followed in March 2024. The customers' money, once thought lost, would largely be recovered through the bankruptcy, though that recovery did not alter the fact of the theft.
The Five Factors
Aftermath
The collapse propagated through the crypto sector and beyond. FTX's failure imperiled affiliated lenders and counterparties, deepened a broader crypto downturn, and erased the paper fortunes of investors who had treated FTX's valuation as a mark of safety. Retail customers, many of them ordinary savers who had believed the exchange's assurances, faced the prospect of total loss. The venture firms that had validated FTX wrote their stakes to zero.
Yet the financial ending was, unusually, far better than the November 2022 panic implied. Under John J. Ray III, the bankruptcy estate recovered assets aggressively, aided by the recovery in crypto and technology valuations and by stakes FTX held in fast-rising private companies. A court-approved reorganization plan in 2024 provided that the large majority of customers and creditors would be repaid the full dollar value of their claims as of the bankruptcy date, with many set to receive additional interest, a recovery measured in petition-date dollars rather than the appreciated value of the crypto they once held. The theft was real and the loss to customers, as the court found, was real; the estate's success in clawing back assets did not undo the crime that created the hole.
The regulatory and cultural reckoning was equally durable. The case accelerated demands for clearer rules on the custody of crypto assets and the separation of exchanges from affiliated trading firms, and it stripped much of the credibility from the "responsible founder" branding that had insulated the industry's largest players. Bankman-Fried's cooperating deputies received far shorter sentences for their testimony. He remained imprisoned and pursued an appeal, while the phrase "where are the customer funds" hardened into the first question any crypto depositor was advised to ask.
Lessons
- Treat a cultivated persona as marketing, not character; idealism, modest habits, and political access are reputational tools that say nothing about how an institution handles money.
- Insist that an entity holding your assets cannot also trade them for itself; where custody and proprietary trading share an owner, your deposit may quietly become someone else's working capital.
- Distrust any safeguard with a privileged exemption; a risk control that exempts the insiders protects everyone but the people it should restrain.
- Reject self-issued tokens as proof of solvency; collateral an entity creates is a promise valued at a price the entity props up, and it disappears in the panic that tests it.
- Judge a custodian only by its ability to honor withdrawals on demand; valuations, endorsements, and disclosures mean nothing if the assets are not there when holders ask.
