A Google security engineer, Michele Spagnuolo, was arrested and charged over alleged insider trading by placing bets on Polymarket about what Google users were searching, U.S. officials alleged on Wednesday. According to a complaint unsealed by the U.S. Attorney's Office for the Southern District of New York, Spagnuolo used "material nonpublic information" to place bets on who would appear on Google's list of most-searched for individuals for 2025, after Polymarket began offering these markets last fall.
