Sam Bankman-Fried

Definition: Sam Bankman-Fried (SBF) is the founder of cryptocurrency exchange FTX and trading firm Alameda Research, convicted on seven counts of fraud and conspiracy after the $32 billion collapse of his empire in November 2022. He was sentenced to 25 years in federal prison in March 2024.

Key Contributions

  • Founded Alameda Research in 2017, initially profiting from the “kimchi premium” — the price gap between Japanese and Korean crypto markets
  • Founded FTX in 2019, which rapidly grew to become the third-largest crypto exchange globally
  • Pioneered features like tokenized stocks, prediction markets, and cross-collateralized margin on a centralized exchange
  • Became one of the largest political donors in the U.S. during the 2022 election cycle (~$40 million to Democratic candidates)
  • Publicly championed effective altruism (EA) as a philosophical framework for crypto wealth

  • 2017 — Founded Alameda Research, a quantitative crypto trading firm.
  • 2019 — Founded FTX exchange, headquartered in the Bahamas.
  • 2021 — FTX raised $900 million at an $18 billion valuation (July). SBF appeared on magazine covers and testified before Congress.
  • 2022 (January) — FTX valued at $32 billion after a $400 million raise.
  • 2022 (June) — Offered bailouts to struggling firms (Voyager, BlockFi), positioning himself as crypto’s “white knight.”
  • 2022 (November 2) — CoinDesk published a report revealing Alameda’s balance sheet was heavily dependent on FTT, FTX’s own token.
  • 2022 (November 6) — CZ announced Binance would sell its FTT holdings, triggering a bank run on FTX.
  • 2022 (November 11) — FTX, Alameda Research, and 130+ affiliated entities filed for bankruptcy.

  • 2024 (March 28) — Sentenced to 25 years in federal prison.

Controversies

  • Commingling of customer funds — Prosecutors proved FTX funneled billions in customer deposits to Alameda Research to cover trading losses, personal loans, and real estate purchases.
  • Fabricated financials — Alameda’s balance sheet was propped up by illiquid FTT and SRM tokens that Alameda/FTX themselves had created.
  • Political donations — SBF donated tens of millions to both parties (publicly to Democrats, with Republican donations made through intermediaries) to influence crypto regulation.
  • Effective altruism cover — Prosecutors argued SBF used EA rhetoric as a public relations strategy to mask fraud. Multiple EA-aligned organizations returned donations post-collapse.
  • $8 billion shortfall — Customers were left with an ~$8 billion hole. The FTX bankruptcy estate has since recovered substantial assets for distribution.
  • Inner circle plea deals — Caroline Ellison (Alameda CEO), Gary Wang (FTX CTO), and Nishad Singh (FTX engineering director) all pleaded guilty and testified against SBF.

Social Media Sentiment

SBF is universally reviled in the crypto community. On r/CryptoCurrency, r/FTX_Pair, and Crypto Twitter, his name is synonymous with fraud. The phrase “not your keys, not your crypto” saw a massive resurgence after the FTX collapse. His 25-year sentence was widely debated — some viewed it as too lenient relative to the harm caused, while others considered it appropriately severe.
