Google Engineer Faces Charges for Insider Trading Involving Confidential Information

A Google engineer, Michele Spagnuolo, has been charged with insider trading by the U.S. Justice Department, accused of making $1.2 million in profits on Polymarket based on confidential company information. Spagnuolo, who has been with Google for over 12 years and used the identifier "AlphaRaccoon" on Polymarket, allegedly placed wagers exceeding $2.7 million related to Google’s 2025 Year in Search marketing campaign, which reveals the year's most popular searches.

Jay Clayton, the U.S. Attorney for the Southern District of New York, stated, "As alleged, Spagnuolo violated the duties he owed to his employer... Insider trading compromises the integrity of our markets." While platforms like Polymarket prohibit insider trading, breaches have occurred previously; the Justice Department recently charged a U.S. Army soldier for making a significant profit by betting with insider knowledge.

According to the complaint, Spagnuolo utilized confidential internal data about search trends to inform his bets. A spokesperson for Polymarket indicated that the platform is committed to maintaining transparency and has cooperated with legal authorities. Meanwhile, a Google spokesperson confirmed that the employee has been placed on leave, emphasizing that accessing internal marketing material for personal profit is a serious violation of company policy and that they are cooperating with law enforcement in the matter.
