A Google software engineer is facing federal charges after U.S. authorities accused him of using confidential company information to profit from prediction market bets on Polymarket. Prosecutors claim the employee earned more than $1.2 million by placing trades linked to Google’s internal search trend data.
The case is drawing major attention as regulators increase scrutiny on insider trading activities connected to crypto-based prediction platforms.
Google Engineer Accused of Using Confidential Search Data
According to federal prosecutors, Michele Spagnuolo, a 36-year-old software engineer working at Google, allegedly accessed nonpublic company information and used it to place highly profitable bets on Polymarket.
Authorities say the bets were tied to Google’s “Year in Search” rankings and trending search topics before the information became publicly available. Investigators claim he operated under the online alias “AlphaRaccoon” and placed several prediction trades between October and December 2025.
The DOJ alleges that Spagnuolo wagered nearly $2.75 million and generated profits exceeding $1.2 million using insider knowledge connected to Google search data.
DOJ and Regulators Tighten Focus on Prediction Markets
Federal officials charged the engineer with commodities fraud, wire fraud, and money laundering. The case has become one of the biggest insider trading investigations involving prediction markets like Polymarket.
Authorities stated that insider trading laws also apply to event-based prediction platforms when confidential information is used for financial gain.
Google confirmed that the employee has been placed on leave while the investigation continues. The company is reportedly cooperating with law enforcement agencies.
Polymarket also worked with investigators during the inquiry, according to reports.
Growing Concerns Around Polymarket and Crypto Betting Platforms
The incident has renewed debate about the risks of insider trading on decentralized prediction markets. Platforms like Polymarket allow users to place bets on future events ranging from politics and entertainment to business trends and global news.
Regulators have recently increased monitoring of such platforms as they become more popular worldwide.
Industry experts believe this case could lead to stricter rules and compliance requirements for prediction market operators, especially when bets involve sensitive corporate or financial information.
The accused engineer could face significant prison time if convicted on all charges.
