Federal prosecutors charged Google employee Michele Spagnuolo with fraud after he allegedly used confidential internal data to win $1.2 million on Polymarket prediction bets related to search trends in 2025.
Spagnuolo was arrested in New York on Wednesday and released on a $2.25 million bond. According to an unsealed complaint from prosecutors, the employee accessed Google's confidential and commercially valuable internal data to gain an unfair advantage in wagering on Polymarket, a decentralized prediction market platform.
Prosecutors allege that Spagnuolo "knew the outcome of these wagers before the trading public did" by leveraging his access to non-public information about search-related trends. The case highlights growing concerns about insider trading on cryptocurrency-based prediction markets, which operate with minimal regulatory oversight compared to traditional financial exchanges.
Polymarket has grown into a multi-billion-dollar platform where users bet on real-world events, from election outcomes to corporate earnings. The platform's popularity has raised questions about how to prevent market manipulation when traders have access to privileged information.
This case represents one of the first high-profile insider trading charges related to cryptocurrency prediction markets. It underscores potential vulnerabilities in decentralized platforms that operate outside traditional financial regulatory frameworks. The charges against Spagnuolo carry significant implications for how tech companies manage employee access to proprietary data and the legal obligations of users on emerging financial platforms.
The case is being prosecuted by federal authorities in New York. Details about specific bets and the precise nature of the internal data accessed remain under legal review.
