• A Google software engineer has been charged with insider trading, profiting over $1.2 million on Polymarket.
• Michele Spagnuolo allegedly used confidential information regarding Google's annual trends to place bets.
• The case highlights ongoing concerns over insider trading on prediction markets.

Michele Spagnuolo, a 36-year-old software engineer at Google, has been charged with various offenses including commodities fraud and wire fraud after allegedly using insider company information to earn more than $1.2 million on the prediction market platform Polymarket. Authorities claim that Spagnuolo, who resides in Switzerland, accessed confidential internal data to place bets on the most-searched individuals for Google's 2025 Year in Search report, particularly on the indie musician D4vd, whom he predicted would be at the top of the list even as others deemed the likelihood "near-zero."

According to the indictment, Spagnuolo operated under the username AlphaRaccoon and engaged in approximately $2.75 million worth of trades. Spagnuolo's large bets coincided with his access to internal marketing materials, leading to significant concerns over the legality of his actions. "Using such confidential information to place bets is a serious breach of our policies," commented a Google spokesperson. Spagnuolo has since been placed on leave pending the outcome of the investigation.

Federal prosecutors underscore that insider trading undermines market integrity and public trust, stating, "corporate insiders cannot use confidential business information to turn a profit in our markets." This case follows a prior incident where a U.S. soldier allegedly profited from classified information regarding the capture of former Venezuelan leader Nicolás Maduro, raising broader questions about the potential for misconduct on prediction markets, which have gained popularity in recent years.

In response to these issues, Polymarket has reiterated its commitment to maintaining fair and transparent markets. The platform has cooperated with federal authorities in these investigations, emphasizing that insider trading is strictly prohibited and monitored for compliance.
