Google Security Engineer Accused of Insider Trading
A Google security engineer, Michele Spagnuolo, has been arrested and charged with crimes related to bets he allegedly placed on Polymarket using confidential information from Google systems, according to the Justice Department. Spagnuolo, a 36-year-old Italian citizen living in Switzerland, is accused of placing multiple trades on the prediction marketplace last year, netting him a profit of over $1.2 million.
Spagnuolo allegedly abused internal access to Google's nonpublic Year in Search data and placed a series of bets on the most searched people on Google in 2025. The Justice Department said that Spagnuolo's actions compromised the integrity of the markets and that the American people want this greed-driven conduct investigated and prosecuted.
Charges and Penalties
Spagnuolo was charged with violating the Commodity Exchange Act, wire fraud, and money laundering, which carry a combined maximum sentence of up to 50 years in prison. He was also served with a civil complaint by the Commodity Futures Trading Commission, which accused him of insider trading and sought restitution, disgorgement, civil monetary penalties, trading and registration bans, and a permanent injunction against further regulation violations.
According to his company bio, which has since been taken down, Spagnuolo has been employed as a security engineer at Google since 2014, where he built products, specifications, and led multiple projects in the information security unit. A Google spokesperson said the company is working with law enforcement on its investigation and that Spagnuolo has been placed on leave.
Investigation and Evidence
A federal investigator said that Spagnuolo, who used the username "AlphaRaccoon" on Polymarket, took deliberate steps to conceal his use of nonpublic information, including efforts to obscure the source and ownership of his proceeds. Prosecutors noted that Google's internal software tool, which provided Spagnuolo access to search trends, bore a banner that stated "Google Confidential" in red text, and that Spagnuolo confirmed he understood the company's various confidentiality and ethics policies to access the data.
Spagnuolo allegedly created his Polymarket account in May 2024 and placed a series of trades between later that year, risking approximately $2.75 million on 25 outcomes that the market treated as unlikely. The FBI said it traced Spagnuolo's Polymarket account to a cryptocurrency wallet he allegedly used to fund the account and initiate multiple transfers.
Consequences and Implications
Spagnuolo's actions have significant implications for the integrity of the markets and the trust that investors place in companies like Google. The case highlights the importance of enforcing confidentiality and ethics policies within companies and the need for individuals to uphold these standards.
As U.S. attorney for the Southern District of New York, Jay Clayton, said in a statement, "Today's charges reinforce a decades-old message: corporate insiders cannot use confidential information to turn a profit in our markets." The case serves as a reminder that insider trading will not be tolerated and that those who engage in such activities will be held accountable.
