Federal prosecutors charged Google software engineer Michele Spagnuolo, 36, with fraud after he used internal Google Search trend data to earn more than $1.2 million placing bets on the prediction market Polymarket. Prosecutors say Spagnuolo accessed an employee-only Search trends tool and wagered that singer D4vd would be Google's most-searched person of 2025, a bet that paid off. He was released on a $2.25 million bond, and prosecutors say the case highlights how proprietary algorithmic data can become tradable inside information, raising legal and compliance questions for prediction markets and tech companies.
