Google Employee Charged With Insider Trading

Using the Alias “AlphaRaccoon,” Google Employee Michele Spagnuolo Obtained More Than $1.2 Million Trading on Polymarket on the Basis of Confidential Business Information A complaint has been unsealed charging MICHELE SPAGNUOLO, a/k/a “AlphaRaccoon,” a software engineer at Google, with commodities fraud, wire fraud, and money laundering arising from his scheme to misappropriate confidential information from his employer and use that information to place a series of profitable Google-related trades on a prediction market platform. SPAGNUOLO, who resides in Switzerland, was presented today before U.S. Magistrate Judge Sarah Netburn in the Southern District of New York. As alleged in the Complaint unsealed today in Manhattan federal court:(1) SPAGNUOLO is a software engineer at Google. In connection with his role, SPAGNUOLO had access to Google’s internal data systems, including an internal software tool that provided him with access to confidential, nonpublic data. That software tool bore a banner that stated, in part, “Google Confidential” in red text. Indeed, SPAGNUOLO certified his understanding of various Google confidentiality and ethics policies. SPAGNUOLO created an account on Polymarket, which is a prediction marketplace, in May 2024. That account was known as “AlphaRaccoon.” Shortly after accessing Google’s internal information, SPAGNUOLO used the AlphaRaccoon account to place trades in various markets on Polymarket. In total, from on or about October 15, 2025, through on or about December 4, 2025, SPAGNUOLO used the AlphaRaccoon account to risk approximately $2,754,092 on markets related to Google’s internal information. Soon after Google’s information was publicly announced, and the markets resolved, SPAGNUOLO’s AlphaRaccoon account profited approximately $1.2 million based on his use of inside information in connection with bets placed on Polymarket.
