US federal prosecutors have charged a Google engineer with insider trading after he allegedly used privileged access to internal search trend data to place winning bets on Polymarket, netting roughly $1.2 million in profits. The case marks one of the first criminal charges to directly implicate a prediction market platform in an insider trading scheme.
The engineer reportedly exploited non-public data about search query patterns — the kind of real-time signal that would give any trader a significant edge on event-driven markets. Polymarket, which operates as a decentralized prediction market, has grown rapidly in prominence, particularly around political and macro events, making it an increasingly attractive target for information asymmetry plays.
