U.S. prosecutors have charged Google engineer Michele Spagnuolo (aka “AlphaRaccoon”) with insider trading after she allegedly used confidential access to Google’s internal Year in Search data to place lucrative bets on prediction market Polymarket. Authorities say the trades, tied to what queries would rank highest, netted about $1.2 million. The case highlights legal and ethical tensions as employees with privileged tech-platform data increasingly intersect with decentralized betting and crypto-based markets. Industry watchers say the prosecution could set precedents for how existing securities and insider-trading laws apply to prediction markets and digital assets tied to corporate information.
This case shows risks when employees with privileged access use proprietary product data to trade on prediction markets and crypto-linked platforms. Tech professionals must reassess data access controls, insider-trading training and compliance for off-platform markets tied to company metrics.
