Prediction market platform Polymarket is embroiled in another insider trading controversy. The U.S. Department of Justice (DOJ) charged Google security engineer Michele Spagnuolo on Wednesday for allegedly using confidential company information to engage in insider trading on Polymarket. He has been arrested and faces multiple criminal and civil charges. According to the indictment released by the U.S. Attorney's Office for the Southern District of New York, since Polymarket launched the "2025 Google Search Trends" prediction market last autumn, Michele Spagnuolo leveraged his position to access "material non-public information" to accurately bet on which celebrities would top the search rankings. Following the criminal complaint filed by the DOJ, the U.S. Commodity Futures Trading Commission (CFTC) also filed a civil lawsuit, seeking the disgorgement of ill-gotten gains, damages, and the imposition of relevant penalties. **Using Internal Data for Precise Bets** The complaint, signed by FBI Special Agent Brandon Racz, states that Michele Spagnuolo allegedly used internal Google tools to secretly track search trends and transferred $3.8 million in the stablecoin USDC to his Polymarket account as betting capital. Investigation details reveal that he used the pseudonym "AlphaRaccoon" to place bets across multiple contracts. For instance, he bet on rapper D4vd, who caused a public outcry over the alleged murder of a 14-year-old girl, predicting he would become a top search trend in late November. Prosecutors compared the timelines and discovered that just hours before "AlphaRaccoon" placed the bet, Michele Spagnuolo had logged into internal Google systems to view D4vd’s surging search popularity. **Arbitraging Millions and Laundering Funds** To avoid detection, AlphaRaccoon subsequently withdrew 5 million USDC.e (the Ethereum-bridged version of USDC) from Polymarket to a personal wallet. The indictment details that he then used token swap services and privacy-mixing tools to break the chain of custody, attempting to conceal the flow of funds. However, a slip-up occurred: some of the funds eventually flowed into an account at an Italian payment processing institution, which was registered using Michele Spagnuolo’s own identification documents. The indictment states: "Unlike other counterparties in the market, Michele Spagnuolo knew the outcome of the bets before the general public because he possessed highly commercially valuable confidential internal data from Google." Using this non-public information, he personally profited over $1.2 million illegally. After obtaining the funds, he deliberately employed multiple methods to attempt to hide the source and ownership of these illicit gains. According to the indictment, Michele Spagnuolo currently faces multiple felony charges, including commodities fraud, wire fraud, and money laundering. **Polymarket Insider Trading Scandals** It is worth noting that this is the second major insider trading arrest involving the Polymarket platform. Earlier this year, a U.S. Army soldier was arrested for using classified military information regarding a raid against Venezuelan President Nicolas Maduro to place bets on Polymarket in advance. Regarding the involvement of its engineer, a Google spokesperson stated in a release: "We are cooperating fully with law enforcement. While the employee used tools accessible to all Google employees to view marketing data, using this confidential information for betting is a severe violation of company policy. We have placed the employee on administrative leave and will take appropriate disciplinary action."
