Google Security Engineer Charged with Insider Trading on Polymarket Platform
A high-ranking Google security engineer has been charged with insider trading after allegedly using confidential company data to win nearly $1.2 million on a popular decentralized prediction market called Polymarket.
Michele Spagnuolo, a 36-year-old Italian citizen living in Switzerland, was arrested on May 25, 2026, by federal authorities in New York.
Allegations and Investigation
According to the complaint filed by the US Department of Justice, Spagnuolo had been working at Google since 2014 and had access to sensitive information through the company’s internal software tool.
He allegedly used this information to place bets on Polymarket, predicting with near-perfect accuracy whether certain individuals would appear on Google’s annual list of top trending searches.
Financial Transactions and Consequences
Spagnuolo created an anonymous account on Polymarket, known as “AlphaRaccoon,” and began making bets on the platform in October 2025.
He reportedly risked around $2.75 million, but managed to collect nearly $1.2 million in winnings after Google publicly announced its Year in Search results on December 4, 2025.
The investigation revealed that Spagnuolo moved the illicit gains through various cryptocurrency-swapping services, including one that removed wallet addresses from the blockchain.
Legal Action and Implications
Spagnuolo is facing up to 10 years in prison on a commodities fraud count and 20 years each on wire fraud and money laundering counts.
“This case highlights the serious consequences of insider trading and the importance of maintaining the trust and integrity of our markets,” said US Attorney Jay Clayton.
“Corporate insiders must adhere to their duties and refrain from using confidential information for personal gain.”
