FTX marketed itself as a safe, regulated cryptocurrency exchange. Behind the interface, founder Sam Bankman-Fried had granted his trading firm Alameda Research unlimited access to customer deposits through a secret backdoor in the code. When Alameda's risky bets failed and customers attempted to withdraw funds in November 2022, $8 billion was missing. This investigation documents how the fraud was structured, who knew, when they knew, and what the trial evidence revealed about the longest-running scheme in recent financial history.
FTX looked like a professional cryptocurrency exchange. The interface was clean. The customer service was responsive. The founder appeared on CNBC, testified before Congress, and committed to donating most of his wealth to effective altruism. Behind the user dashboard showing account balances and order books, the actual structure was different.
Customer deposits sent to FTX were recorded in an internal database account with the label "fiat@". This account was not segregated from Alameda Research's trading operations. Gary Wang, FTX's co-founder and chief technology officer, testified at trial that he had written code in 2019—at Sam Bankman-Fried's direction—that allowed Alameda to maintain a negative balance of up to $65 billion on the FTX platform. No other customer had this exemption. When Alameda's balance went negative, it meant the firm was borrowing customer deposits.
FTX's terms of service contained explicit language stating that customer assets were held separate from company assets and were not used for trading. The reality was documented in trial exhibits: Alameda withdrew approximately $8 billion in customer funds between 2020 and 2022. Caroline Ellison, who served as CEO of Alameda Research, testified that Sam Bankman-Fried personally approved the use of FTX customer funds to repay Alameda's lenders when the 2022 crypto downturn left the trading firm unable to meet margin calls.
The relationship between FTX and Alameda Research was not disclosed in investor materials, loan agreements, or customer communications. Alameda was described publicly as one of many market makers on the exchange. Internal documents showed a different relationship. Alameda had API access that allowed it to see customer order flow before trades executed—an advantage in trading called front-running. Alameda was exempted from FTX's auto-liquidation system, meaning positions that would have been automatically closed for other traders remained open for Alameda. And Alameda had the ability to borrow customer deposits without limit.
Caroline Ellison presented spreadsheets during her testimony showing that by June 2022, Alameda owed FTX $14 billion. She testified she had created eight different versions of Alameda's balance sheet to show lenders—each presenting a different picture of how much the firm had borrowed and from where. All eight were misleading. The accurate version, which she did not share with lenders, showed Alameda was insolvent and its solvency depended entirely on continued access to FTX customer deposits.
"I sent them the balance sheets, and I knew that they were misleading. I knew that if people saw our actual balance sheets, that would not be good for FTX or Alameda."
Caroline Ellison, testimony — United States v. Bankman-Fried, October 2023Nishad Singh, FTX's director of engineering, testified that he discovered in 2022 that the amount Alameda had borrowed from FTX was $8 billion more than he had previously understood. He confronted Bankman-Fried. The response, according to Singh's testimony, was that the situation was under control and that Alameda's positions would recover. Singh did not resign, report the discrepancy to the board, or notify customers. He continued processing transfers and remained in his role until the exchange collapsed.
Bankruptcy filings and trial evidence documented how FTX customer deposits were spent. Alameda used the funds to repay loans from Genesis Global Capital, Voyager Digital, and other lenders during the 2022 market downturn when crypto asset prices fell and lenders issued margin calls. Rather than liquidate positions or admit insolvency, Alameda drew on FTX customer deposits to meet the calls.
FTX and Alameda together made over $5 billion in venture investments, including stakes in Sequoia Capital funds, Anthropic (an AI research lab), and hundreds of smaller cryptocurrency and technology companies. These investments were recorded on balance sheets as assets, but they were illiquid and could not be sold to meet customer withdrawal requests.
Sam Bankman-Fried and other FTX executives took personal loans from Alameda Research, which had itself borrowed the funds from FTX customers. Court filings identified $1 billion loaned to Bankman-Fried, $543 million to Nishad Singh, and $55 million to Ryan Salame, co-CEO of FTX Digital Markets. The loans were documented in internal spreadsheets but not disclosed to investors, lenders, or customers.
FTX executives purchased at least $300 million in Bahamas real estate, including a $30 million penthouse where Bankman-Fried lived with nine other executives and employees. Bankruptcy estate investigators identified 38 separate real estate purchases funded by FTX entities between 2021 and 2022, many held in the names of parents or employees to obscure beneficial ownership.
Bankman-Fried became the second-largest individual donor to Democratic candidates in the 2022 election cycle, contributing over $40 million in disclosed donations. Trial testimony and DOJ filings alleged another $100 million in unreported contributions made through straw donors—employees and executives who were told which candidates to donate to and were then reimbursed by FTX. Ryan Salame, who managed FTX's Bahamas operations, separately donated $24 million to Republican candidates using the same reimbursement structure. Both Bankman-Fried and Salame were convicted on charges related to campaign finance violations.
On November 2, 2022, CoinDesk published a leaked version of Alameda Research's balance sheet. The document showed $14.6 billion in assets, of which $5.8 billion was FTT—FTX's proprietary exchange token. The revelation that Alameda's solvency depended on the value of a token issued by its sister company raised immediate questions about the relationship between the two entities and the real value of Alameda's assets.
Four days later, Changpeng Zhao, CEO of Binance—the world's largest cryptocurrency exchange—tweeted that Binance would liquidate the approximately $580 million in FTT tokens it still held from its 2021 exit as an FTX investor. CZ did not explicitly accuse FTX of fraud in the tweet, but the message was clear: Binance no longer wanted exposure to FTX.
FTX customers attempted to withdraw $6 billion over the next three days. The exchange could not process the requests. The funds were not there. On November 8, Binance signed a non-binding letter of intent to acquire FTX, which briefly stabilized customer panic. Then Binance conducted due diligence—examined the books, reviewed the code, traced the customer deposits. Within 24 hours, Binance withdrew. The official statement cited "reports regarding mishandled customer funds and alleged US agency investigations."
Sam Bankman-Fried attempted to raise emergency capital. He contacted venture investors, sovereign wealth funds, and rival exchanges. He sent messages promising that FTX had the assets to cover customer deposits if given time to liquidate positions. None of the capital materialized. On November 11, 2022, FTX Trading Ltd, FTX US, Alameda Research, and approximately 130 affiliated entities filed for Chapter 11 bankruptcy. The petition listed over one million creditors.
John J. Ray III was appointed CEO of the FTX estate for the purpose of liquidation. Ray had previously overseen the bankruptcy of Enron—at the time the largest and most complex corporate fraud in American history. Six days after his appointment, Ray filed a declaration that began: "Never in my career have I seen such a complete failure of corporate controls and such a complete absence of trustworthy financial information as occurred here."
The declaration detailed what Ray's team found. FTX had no accounting department. Multi-billion dollar transactions were recorded in QuickBooks. Expenses were approved via emoji reactions in Slack channels. Private keys to cryptocurrency wallets holding customer assets were stored in personal email accounts of employees—some of whom had already left the company. Corporate funds and customer funds were held in the same bank accounts and database entries with no segregation. There was no board of directors for FTX Trading Ltd. There were no board minutes, no audit committee, no compliance infrastructure beyond what was required to maintain the appearance of a regulated exchange.
Bankruptcy investigators identified $8.9 billion in customer assets that could not be located. Some assets were eventually recovered: $3.4 billion in cryptocurrency held in wallets FTX still controlled, $1.4 billion held by Bahamian liquidators, hundreds of millions in venture investments that could be liquidated, and real estate that could be sold. By late 2024, the bankruptcy estate had recovered over $7 billion—far more than initial projections, but still short of what customers were owed if crypto assets were valued at November 2022 prices rather than the lower prices at which they were liquidated.
Federal prosecutors charged Sam Bankman-Fried in December 2022 with seven counts of wire fraud and conspiracy. Caroline Ellison, Gary Wang, and Nishad Singh all pleaded guilty and agreed to cooperate. The trial began in October 2023 in Manhattan federal court before Judge Lewis Kaplan.
The prosecution's case relied heavily on the testimony of the three cooperating witnesses, supplemented by internal documents, Signal messages, and code repositories. Caroline Ellison testified for three days. She confirmed that Bankman-Fried had directed her to use FTX customer funds to repay Alameda's lenders, that he had reviewed and approved the misleading balance sheets, and that he had told her the situation was manageable even as the shortfall grew to $8 billion. She presented contemporaneous spreadsheets showing the calculations.
Gary Wang walked the jury through the code. He explained the "allow negative" feature, the exemption from auto-liquidation, and the database structures that recorded customer deposits and Alameda borrows in ways that obscured the relationship. Wang testified he knew the structure was wrong and that he had raised concerns, but that Bankman-Fried had assured him it was legal and that outside lawyers had reviewed the arrangement.
Nishad Singh testified about the political donations, the real estate purchases, and his discovery in 2022 of the full extent of Alameda's borrowing. He acknowledged he should have resigned or reported the fraud but said he believed Bankman-Fried's assurances that the shortfall could be covered.
"I thought I was a good actor in a good story, and actually I was a bad actor in a bad story."
Nishad Singh, testimony — United States v. Bankman-Fried, October 2023The defense strategy was to argue that Bankman-Fried had made business mistakes but had not intended to defraud anyone, that he had relied on advice from lawyers and accountants, and that the collapse was caused by a market downturn rather than fraud. Bankman-Fried testified in his own defense—a decision his lawyers reportedly opposed.
The testimony did not help. Bankman-Fried claimed he had not known the extent of Alameda's borrowing, contradicting documents showing he received daily balance reports. He claimed he thought customer funds were safe, contradicting testimony that he had personally approved their use. He claimed the lawyers had approved the structure, but could not name which lawyers or produce documentation of the approval. Judge Kaplan sustained dozens of prosecution objections on grounds that Bankman-Fried was not answering the questions asked.
On November 2, 2023—almost exactly one year after the CoinDesk article that triggered the collapse—the jury convicted Sam Bankman-Fried on all seven counts. Deliberation lasted four hours.
Prosecutors requested a sentence of 40 to 50 years. The defense requested 5 to 6.5 years, arguing Bankman-Fried was likely to repay customers through the bankruptcy estate's asset recovery. Judge Lewis Kaplan sentenced Bankman-Fried to 25 years on March 28, 2024. In his sentencing statement, Kaplan noted that Bankman-Fried had committed perjury on the witness stand, had shown no remorse, and had obstructed justice by attempting to influence witness testimony before trial.
Caroline Ellison was sentenced to two years in prison in September 2024, reduced from a guideline range of decades due to her cooperation. Gary Wang received no prison time—sentenced to time served and forfeiture based on his substantial assistance to the government. Nishad Singh received three years supervised release, also with no prison time due to cooperation. Ryan Salame, who did not cooperate, was sentenced to 7.5 years for campaign finance violations and operating an unlicensed money transmitting business.
Several regulatory and systemic questions remain unresolved. FTX was not regulated as a securities exchange because it claimed to trade commodities, not securities. It was not regulated as a commodities exchange because it operated offshore. It was not subject to banking regulation because it did not call itself a bank. The regulatory gaps that allowed FTX to operate with minimal oversight remain largely in place.
Venture investors who promoted FTX—Sequoia Capital published a hagiographic profile of Bankman-Fried on its website, later deleted—have faced criticism but no legal consequences. The profile described Bankman-Fried playing League of Legends during a pitch meeting as evidence of his ability to multitask and optimize. After the collapse, Sequoia wrote to limited partners that it was in the business of taking risk and that some investments would surprise to the downside. The firm marked its entire $210 million FTX investment to zero.
Celebrity endorsers including Tom Brady, Gisele Bündchen, and Larry David appeared in FTX advertisements promoting the exchange as safe and easy to use. Several endorsers face civil litigation from customers who claim they relied on celebrity endorsements in deciding to deposit funds. Whether celebrity endorsement constitutes an actionable misrepresentation when the endorser had no knowledge of the underlying fraud is an open legal question.
As of late 2024, the FTX bankruptcy estate projects it will recover 100% of customer claims valued at the November 2022 bankruptcy date—approximately $8.9 billion. Customers whose accounts held Bitcoin, which was worth approximately $16,000 at bankruptcy and later rose above $60,000, will not receive the appreciation. They will receive the November 2022 value in dollars. Customers whose accounts held FTT token, which became worthless, will receive nothing for those holdings.
The distinction matters. Some customers argue the correct measure of recovery is return of the actual crypto assets, not their dollar value at a historical date. The bankruptcy code provides for dollar-denominated claims, not in-kind return of commodities. Customers who held Bitcoin on FTX when it was worth $16,000 and watched it rise to $60,000 while waiting for bankruptcy proceedings effectively lost the appreciation despite full nominal recovery of their November 2022 claim amount.
FTX is the largest cryptocurrency fraud prosecuted to date, but it follows a pattern visible in earlier cases. Mt. Gox, once the largest Bitcoin exchange, collapsed in 2014 after its CEO admitted approximately 850,000 Bitcoin—worth $450 million at the time—had been stolen or lost. QuadrigaCX, a Canadian exchange, collapsed in 2019 after its founder died and investigators concluded approximately $190 million in customer funds had been misappropriated. Wirecard, a German payment processor that offered cryptocurrency services, collapsed in 2020 when auditors admitted €1.9 billion in cash probably did not exist.
The common elements across cases are commingling of customer and company funds, offshore incorporation to avoid regulatory oversight, charismatic founders who cultivated public trust, and delayed discovery of the fraud until customers attempt mass withdrawals. What differed in FTX was the scale, the sophistication of the participants, and the explicitness of the documentary evidence showing intent.
"Never in my career have I seen such a complete failure of corporate controls and such a complete absence of trustworthy financial information as occurred here. From compromised systems integrity and faulty regulatory oversight abroad, to the concentration of control in the hands of a very small group of inexperienced, unsophisticated and potentially compromised individuals, this situation is unprecedented."
John J. Ray III, Declaration in Support of Chapter 11 Petitions — November 17, 2022Sam Bankman-Fried created FTX with the backdoor already installed. The code granting Alameda special privileges was written in 2019, before FTX had significant customer deposits to steal. This was not a company that went bad—it was structured from inception to allow the founder to use customer deposits as a personal line of credit.
The fraud succeeded as long as withdrawals remained smaller than deposits. FTX grew rapidly in 2020 and 2021 as cryptocurrency prices rose and trading volumes increased. New customer deposits exceeded withdrawals, allowing Alameda to borrow ever-larger amounts without the shortfall becoming visible. When crypto prices crashed in 2022, trading volumes fell, customer deposits slowed, and Alameda's losses—magnified by leverage and concentrated bets—exceeded the pace of new customer funds coming in. The structure was always unsustainable. It simply became visible in 2022.
The participation of venture capital firms, celebrity endorsers, and institutional investors provided legitimacy that retail customers relied on in deciding to trust FTX with their funds. Sequoia Capital is among the most respected venture firms in the world. Its endorsement signaled due diligence and validation. In reality, Sequoia's due diligence apparently consisted of watching Bankman-Fried play video games during a pitch meeting and concluding he was a genius. No venture investor has been charged with fraud. The question of whether investors have a duty to verify claims made by founders before publicly promoting them remains largely unanswered in law.
Three executives cooperated with prosecutors, received reduced sentences, and provided the evidence that convicted Bankman-Fried. All three testified they knew the structure was wrong but believed Bankman-Fried's assurances that it was legal or that the shortfall could be covered. Whether this constitutes a defense to fraud charges—reliance on the representations of a co-conspirator—is generally not accepted. But the cooperating witnesses' relatively light sentences reflect prosecutorial recognition that the structure was created and controlled by Bankman-Fried, and that their cooperation was essential to securing his conviction.
The FTX case will likely serve as the reference point for cryptocurrency fraud prosecutions going forward—not because the fraud was novel, but because the documentary evidence was so explicit and the trial testimony so detailed that nearly every element of the scheme is now documented in a public record. The case confirms that cryptocurrency exchanges, despite operating with novel technology and claiming to exist outside traditional regulatory frameworks, are subject to the same wire fraud statutes that have applied to financial frauds for over a century. The technology was new. The crime was not.
