Wang pleaded guilty in December 2022 to four counts of wire fraud and conspiracy, served as a principal cooperating witness against former CEO Sam Bankman-Fried, and was sentenced in November 2024 to time served with three years of supervised release and $11 billion in forfeiture obligations.","sections":[{"content":"Zixiao 'Gary' Wang (born c. 1993 in China) emigrated to the United States at approximately age eight and attended Cherry Hill High School East in New Jersey. He studied mathematics and computer science at MIT, graduating in 2015, where he met Sam Bankman-Fried as a fellow member of the Epsilon Theta coed fraternity and roommate. After MIT, Wang joined Google, working on the Google Flights product to aggregate airline ticket prices. In 2017, Bankman-Fried persuaded Wang to leave Google and join Alameda Research, the proprietary trading firm Bankman-Fried had co-founded. In 2019, Wang and Bankman-Fried co-founded FTX, a cryptocurrency derivatives exchange based in Hong Kong and later the Bahamas, where Wang served as Chief Technology Officer. At FTX's peak valuation in 2022, Wang held approximately 17% equity in FTX and 10% of Alameda Research, making him one of the largest individual shareholders. He was described internally as the primary architect of FTX's trading platform software infrastructure.","heading":"Background and Role at FTX","sources":[{"url":"https://en.wikipedia.org/wiki/Gary_Wang_(American_businessman)","name":"en.wikipedia.org","type":"other","credibility":3},{"url":"https://www.theblock.co/post/186476/who-is-billionaire-ftx-co-founder-gary-wang-and-why-is-he-still-committing-code","name":"theblock.co","type":"other","credibility":3},{"url":"https://www.coindesk.com/layer2/2022/11/22/who-is-gary-wang-the-mysterious-co-founder-of-ftx-and-alameda-research","name":"coindesk.com","type":"other","credibility":3}],"severity":"medium"},{"content":"According to court filings and Wang's own sworn testimony, Bankman-Fried directed Wang to insert code into FTX's trading platform that granted Alameda Research a series of special privileges unavailable to ordinary FTX customers. These privileges included: (1) an 'allow_negative' flag enabling Alameda to hold a negative balance — effectively an unlimited, undisclosed credit line — on the FTX platform; (2) a $65 billion notional line of credit extended from FTX customer deposits to Alameda without customer consent; and (3) an exemption from the platform's standard auto-liquidation mechanisms that would have closed losing positions. Wang testified that Bankman-Fried ordered him and former engineering director Nishad Singh to implement the 'allow_negative' feature in 2019. Alameda drew on this hidden credit facility to fund speculative investments, venture capital commitments, and political donations. By the time FTX collapsed in November 2022, Alameda's use of customer funds had created an $8 billion shortfall that FTX could not cover when customers sought to withdraw their assets. The SEC separately alleged that Wang created a software backdoor in FTX's platform which allowed Alameda to divert customer funds for its own trades.","heading":"The FTX Fraud Scheme","sources":[{"url":"https://slate.com/technology/2023/10/gary-wang-sam-bankman-fried-trial-testimony-ftx-alameda-backdoor.html","name":"slate.com","type":"other","credibility":3},{"url":"https://courthousenews.com/ftx-co-founder-who-cooperated-against-bankman-fried-avoids-prison-time/","name":"courthousenews.com","type":"other","credibility":3},{"url":"https://www.sec.gov/enforcement-litigation/litigation-releases/lr-25617","name":"sec.gov","type":"other","credibility":3},{"url":"https://www.dlnews.com/articles/regulation/ftx-cto-gary-wang-avoids-prison-for-role-in-fraud/","name":"dlnews.com","type":"other","credibility":3}],"severity":"medium"},{"content":"On December 18, 2022 — within weeks of FTX's November 2022 bankruptcy filing — Wang pleaded guilty in the U.S. District Court for the Southern District of New York to four criminal counts: wire fraud, conspiracy to commit wire fraud, conspiracy to commit securities fraud, and conspiracy to commit commodities fraud. He entered a cooperation agreement with prosecutors, making him among the first FTX insiders to cooperate with the government. The charges collectively carried a maximum statutory penalty of 50 years' imprisonment. Simultaneously, the U.S. Securities and Exchange Commission (SEC) charged Wang alongside Caroline Ellison with defrauding equity investors in FTX. Wang was released on a $250,000 bond pending sentencing. The Department of Justice indicated it would recommend a reduced sentence contingent on the quality and extent of Wang's cooperation.","heading":"Criminal Charges and Guilty Plea","sources":[{"url":"https://www.cnbc.com/2022/12/22/ftxs-gary-wang-alamedas-caroline-ellison-plead-guilty-to-federal-charges-cooperating-with-prosecutors.html","name":"cnbc.com","type":"other","credibility":3},{"url":"https://www.sec.gov/newsroom/press-releases/2022-234","name":"sec.gov","type":"other","credibility":3},{"url":"https://www.coindesk.com/policy/2022/12/22/alameda-chief-caroline-ellison-ftxs-gary-wang-plead-guilty-to-fraud-charges","name":"coindesk.com","type":"other","credibility":3},{"url":"https://www.washingtonpost.com/business/2022/12/21/caroline-ellison-fraud-charges/","name":"washingtonpost.com","type":"other","credibility":3}],"severity":"medium"},{"content":"Wang was the first of Bankman-Fried's co-conspirators to begin cooperating with federal prosecutors following FTX's collapse, and the first cooperating witness to take the stand at Bankman-Fried's criminal trial, which began in October 2023. Wang testified for approximately three days, providing detailed technical explanations of how the fraud was engineered, including the specific code changes he was ordered to make to give Alameda preferential access to customer funds. He testified directly that Bankman-Fried was aware of the $8 billion shortfall between FTX's customer liabilities and available assets even as Bankman-Fried publicly posted reassurances that 'FTX is fine. Assets are fine.' An Assistant U.S. Attorney described Wang as 'the easiest cooperating witness he had ever worked with,' crediting him with essentially deciphering half of the prosecution's case for the government. Bankman-Fried was convicted in November 2023 on all seven counts and subsequently sentenced to 25 years in federal prison.","heading":"Cooperation and Trial Testimony","sources":[{"url":"https://courthousenews.com/ftx-co-founder-who-cooperated-against-bankman-fried-avoids-prison-time/","name":"courthousenews.com","type":"other","credibility":3},{"url":"https://www.scmp.com/news/world/united-states-canada/article/3287444/sam-bankman-frieds-ex-deputy-gary-wang-spared-prison-time-over-ftx-fraud","name":"scmp.com","type":"other","credibility":3},{"url":"https://slate.com/technology/2023/10/gary-wang-sam-bankman-fried-trial-testimony-ftx-alameda-backdoor.html","name":"slate.com","type":"other","credibility":3},{"url":"https://bettermarkets.org/newsroom/memo-ftx-co-conspirator-gary-wangs-cooperation-in-convicting-ftx-kingpin-sam-bankman-fried-and-subsequent-good-works-are-important-but-should-not-be-a-get-out-of-jail-free-card/","name":"bettermarkets.org","type":"other","credibility":3}],"severity":"medium"},{"content":"On November 20, 2024, Judge Lewis A.

Wang was also ordered to forfeit $11 billion jointly with Bankman-Fried, Ellison, and Singh. Judge Kaplan stated Wang deserved 'a world of credit' for his cooperation and its role in securing Bankman-Fried's conviction. Wang addressed the court, stating he was 'deeply sorry' and acknowledged making numerous poor decisions. Prosecutors noted that in addition to his trial testimony, Wang had used his programming skills post-plea to build fraud detection tools for the U.S. government to monitor stock and cryptocurrency markets for illicit activity; many specifics were redacted from the public sentencing filing to protect the tools' effectiveness. Wang was the fifth and final former FTX executive to be sentenced in the matter. Separately, the SEC obtained final consent judgments against Wang, permanently enjoining him from violating securities antifraud provisions and imposing an eight-year officer-and-director bar along with a five-year conduct-based injunction.","heading":"Sentencing and Regulatory Penalties","sources":[{"url":"https://www.coindesk.com/policy/2024/11/20/former-ftx-cto-gary-wang-wont-have-to-serve-prison-time-judge-rules","name":"coindesk.com","type":"other","credibility":3},{"url":"https://www.cnbc.com/2024/11/20/ftx-co-founder-gary-wang-avoids-prison-time-for-role-in-crypto-fraud.html","name":"cnbc.com","type":"other","credibility":3},{"url":"https://www.theblock.co/post/327421/ftx-co-founder-gary-wang-receives-no-prison-time-following-fallout-of-crypto-exchange-reports","name":"theblock.co","type":"other","credibility":3},{"url":"https://www.sec.gov/enforcement-litigation/litigation-releases/lr-26450","name":"sec.gov","type":"other","credibility":3},{"url":"https://www.blockhead.co/2024/11/14/ex-ftx-exec-gary-wang-builds-anti-fraud-tool-for-us-gov-ahead-of-sentencing/","name":"blockhead.co","type":"other","credibility":3}],"severity":"medium"},{"content":"According to court filings submitted at the time of sentencing, Wang worked with U.S. government prosecutors to design and build software tools for detecting potential financial fraud in public equity markets, and was separately developing a tool to identify illicit activity on cryptocurrency exchanges.
