Google Engineer Accused of Polymarket Insider Trading Says He Was Just ‘Gambling’
A Google engineer is facing criminal charges for insider trading related to wagers on the Polymarket prediction platform. The case has sparked a broader legal debate over whether event-based prediction markets should be classified as regulated financial swaps or as gambling.
Why it matters
The outcome of this case could set a legal precedent for how prediction markets are regulated in the U.S., potentially impacting the future of the entire industry.
Spagnuolo, who has been placed on leave from Google, is accused of committing commodities fraud, wire fraud, and money laundering. Using the alias “AlphaRaccoon,” he allegedly made a series of wagers on Polymarket’s flagship platform that resulted in profits totaling over $1.2 million. According to the criminal complaint, “AlphaRaccoon” correctly wagered that the singer D4vd, who gained notoriety for his suspected connection to a grisly killing, would be Google’s most-searched person of the year in 2025. (D4vd was later charged with murder; he pleaded not guilty.)
