Google Engineer Charged in $1M Polymarket Insider Trading Case

A Google security engineer, Michele Spagnuolo, was arrested in New York and charged with commodities fraud, wire fraud, and money laundering for using confidential Google data to place bets on Polymarket, earning more than $1 million—including a $1.2 million win predicting Google’s most‑searched person of 2025. Prosecutors say trades were made Oct–Dec 2025 with insider information. Google says the employee is on leave and violated policies, while Polymarket cooperated with investigators. The case underscores heightened scrutiny of insider trading on prediction markets.
