was supposed to be the “safe” exchange — the one with institutional backing, regulatory compliance, and a founder who testified before Congress. When it collapsed in November 2022, it revealed that billions in customer funds had been funneled to an affiliated trading firm and lost. The bankruptcy was one of the largest in US history. The SBF story is the definitive cautionary tale about reputation risk: in crypto, a polished image and big-name backers are not proof of solvency. Only proof of reserves is.
The rise of SBF
Sam Bankman-Fried (SBF) graduated from MIT in 2014 and worked as a trader at Jane Street Capital, a quantitative trading firm. In 2017, he left to found Alameda Research, a crypto trading firm that exploited arbitrage opportunities — most famously, the price gap between Bitcoin on US and Korean exchanges (the “kimchi premium”). Alameda was profitable in its early years and became one of the largest crypto trading firms in the world.
In 2019, SBF and Gary Wang (a former Google engineer) launched FTX, a crypto derivatives exchange. FTX differentiated itself with professional-grade infrastructure, innovative products (prediction markets, tokenized stocks), and aggressive marketing. By 2021, FTX was valued at $25 billion, backed by Sequoia Capital, SoftBank, Temasek, Tiger Global, and other blue-chip investors. SBF became a billionaire and a fixture in Washington DC, donating heavily to political causes and testifying before Congress as the “responsible” voice of crypto.
The image was carefully cultivated: the rumpled hoodie, the Toyota Corolla, the effective-altruism rhetoric about giving away his fortune. It worked. Politicians, venture capitalists, journalists, and the public concluded that SBF was different — that FTX was the safe, regulated exchange. None of it was true.
The secret: FTX and Alameda were entangled
The critical fact that the public didn't know was that FTX and Alameda Research were not independent entities. SBF controlled both. And the relationship was not arms-length — FTX was lending customer funds to Alameda, which used them for trading (and lost them).
The mechanism involved FTT, a token FTX created. FTT was ostensibly an exchange utility token (fee discounts, buyback-and-burn), but it served a darker purpose: Alameda's balance sheet was largely composed of FTT — a token that FTX itself had created and that had no value independent of FTX's solvency. When CoinDesk revealed this on November 2, 2022, it exposed the circularity: Alameda's “assets” were FTX's own tokens, and FTX's “health” depended on Alameda's solvency, which depended on FTT's value, which depended on FTX's health. It was a confidence trick.
The core fraud was simple in substance: FTX took customer deposits and lent them to Alameda Research, which used them to trade (and to make venture investments, buy real estate, and make political donations). When Alameda's trades went bad — especially during the 2022 market crash — the borrowed money was gone. But FTX's customers still saw balances on the exchange interface; the money just wasn't there. When the bank run started and customers tried to withdraw, FTX couldn't pay. The hole was approximately $8 billion.
The bank run: November 2022
On November 6, 2022, CZ (Changpeng Zhao, CEO of Binance) announced that Binance would sell its ~$580 million FTT position, citing the CoinDesk article. Whether this was a competitive move or genuine risk management, it triggered a bank run. FTX customers rushed to withdraw. In approximately 72 hours, FTX processed ~$6 billion in withdrawal requests.
On November 8, FTX halted withdrawals. SBF scrambled for a bailout, reaching out to Binance, then to venture capitalists, then to the Bahamas government. Binance signed a non-binding letter of intent to acquire FTX, reviewed the books, and walked away the next day — reportedly because the hole was so large and the records so chaotic that even Binance couldn't assess the situation.
On November 11, 2022, FTX, Alameda Research, and approximately 130 affiliated entities filed for Chapter 11 bankruptcy. SBF resigned as CEO. John J. Ray III — the restructuring expert who had managed the Enron bankruptcy — was appointed to oversee the estate.
John Ray's testimony: “unprecedented” failure
John J. Ray III's written testimony to the US House Financial Services Committee on December 13, 2022, is one of the most damning corporate assessments ever filed. He testified:
- “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.”
- Customer funds were commingled with Alameda's funds.
- There was no independent board of directors, no proper accounting, and no internal controls.
- SBF and his inner circle used corporate funds to buy personal real estate in the Bahamas and make political donations.
- The exchange's software allowed Alameda to withdraw customer funds with a special exemption that other accounts didn't have.
Ray's testimony made clear that this was not a complex technical failure — it was old-fashioned embezzlement, enabled by a complete absence of corporate governance. The crypto sophistication was a smokescreen; the fraud was simple.
The timeline
Tap any event to expand its story.
Sam Bankman-Fried (SBF), a former Jane Street trader, founds Alameda Research — a crypto quantitative trading firm. It profits from arbitrage between US and Asian crypto exchanges (the "kimchi premium"). Alameda is the seed of everything that follows — and the root of the problem.
SBF and Gary Wang launch FTX, a crypto derivatives exchange based in Antigua and Barbuda with operations in the Bahamas. The pitch: a professional-grade exchange with better technology and lower fees than incumbents. It grows rapidly, backed by a who's-who of venture capital.
FTX raises at a $25 billion valuation, with backers including Sequoia, SoftBank, Temasek, and Tiger Global. SBF becomes a billionaire, moves to the Bahamas, and begins political donations and high-profile sponsorships (Miami Heat arena naming rights, Super Bowl ads). He cultivates an image of the "safe, responsible" crypto founder.
During the 2022 crypto contagion (triggered by the Terra/Luna collapse), SBF positions himself as the industry's lender of last resort — bailing out BlockFi and considering, then passing on, Celsius. This burnishes his reputation as crypto's adult in the room. Meanwhile, behind the scenes, Alameda is deeply insolvent.
CoinDesk publishes a bombshell article revealing that Alameda Research's balance sheet is heavily composed of FTT — FTX's own exchange token. This reveals that FTX and Alameda are far more entangled than disclosed, and that Alameda's "assets" are largely a token FTX itself created.
CZ (Changpeng Zhao, Binance CEO) announces on Twitter that Binance will liquidate its ~$580 million FTT position. This triggers a bank run on FTX. Customers rush to withdraw. FTX processes ~$6 billion in withdrawals in 72 hours.
FTX halts withdrawals. It emerges that FTX has a ~$8 billion hole in its balance sheet — customer funds were lent to Alameda Research, which lost them in bad trades. SBF attempts a bailout from Binance; Binance signs a non-binding LOI, then walks away after reviewing FTX's books.
FTX, Alameda Research, and ~130 affiliated entities file for Chapter 11 bankruptcy. SBF resigns as CEO. John J. Ray III — who managed the Enron bankruptcy — is appointed CEO. He later testifies that FTX had the worst corporate governance he has ever seen.
SBF is arrested in the Bahamas at the request of US prosecutors. He is extradited to the US and charged with eight counts of fraud and conspiracy. He is released on a $250 million bond (the largest in US criminal history at the time) under house arrest at his parents' home.
SBF's trial begins in October 2023. Former inner circle members (Caroline Ellison, Gary Wang, Nishad Singh) testify against him. In November 2023, the jury convicts him on all seven counts after approximately 4 hours of deliberation. In March 2024, he is sentenced to 25 years in federal prison.
The trial
SBF's trial in October 2023 was a spectacle. His inner circle — Caroline Ellison (Alameda CEO and SBF's on-off girlfriend), Gary Wang (FTX co-founder), and Nishad Singh (FTX engineering lead) — all pleaded guilty and testified against him. Their testimony described a simple fraud: SBF directed them to send customer funds to Alameda, Alameda lost them, and they lied about it.
SBF took the stand in his own defense and performed poorly — evasive, unable to recall key facts, and contradicting his own public statements. The jury convicted him on all seven counts (wire fraud, conspiracy to commit wire fraud, conspiracy to commit securities fraud, conspiracy to commit commodities fraud, and conspiracy to commit money laundering) after approximately four hours of deliberation. In March 2024, he was sentenced to 25 years in federal prison. He appealed in April 2024; in June 2026, a federal appeals court denied his appeal.
The recovery
Under John Ray's management, the FTX estate recovered significantly more than expected — reportedly $14–$16 billion in assets, against ~$11 billion in customer claims. The bankruptcy court approved a repayment plan in October 2024, and cash distributions began in February 2025. Because the recovered assets exceed the claims, most customers are recovering the full claimed dollar value — though, as with Mt. Gox, the repayments are denominated in the dollar value at the time of bankruptcy (November 2022), not the current value of any crypto they held. A customer who had 1 BTC on FTX (worth ~$16,000 in Nov 2022) receives ~$16,000, not the current Bitcoin price. The years of lost opportunity are not compensable.
FTX raised ~$2 billion from top-tier venture capital firms — Sequoia, SoftBank, Temasek, Tiger Global, Paradigm, and others. Most did no meaningful due diligence on FTX's financial controls or the FTX-Alameda relationship. Sequoia marked its $214 million FTX investment down to zero. The episode damaged the reputation of VC due diligence in crypto and raised questions about whether “smart money” was doing any real work, or simply following the hype.
Key takeaways
- FTX was the “safe” exchange with blue-chip backers and a politically connected founder — and it was a fraud. Customer funds were funneled to Alameda Research and lost in bad trades. The hole was ~$8 billion.
- The fraud was not technically sophisticated — it was old-fashioned embezzlement enabled by a complete absence of corporate governance. John J. Ray III (Enron restructuring chief) called it the worst he had ever seen.
- The collapse was triggered by a CoinDesk article revealing Alameda's FTT-heavy balance sheet, followed by a Binance-triggered bank run. FTX halted withdrawals and filed for bankruptcy within 9 days.
- SBF was convicted on all seven fraud counts in November 2023 and sentenced to 25 years in federal prison in March 2024.
- The estate recovered enough to repay most customer claims at their November 2022 dollar value — a plan approved in October 2024, with distributions beginning in February 2025 — but not the current crypto value. The pattern — centralized exchange fails, customers become unsecured creditors — is the same as Mt. Gox a decade earlier.
- Reputation, VC backing, and political connections are not proof of solvency. Only cryptographic proof of reserves — or self-custody — eliminates counterparty risk.
