U.S. prosecutors have charged Google engineer Michele Spagnuolo with insider trading after she allegedly used confidential access to Google’s Year in Search and user-search data to place roughly $1.2 million in bets on Polymarket. Authorities say Spagnuolo purchased contracts predicting search trends before results were public, converting privileged internal knowledge into cryptocurrency-linked profits. The case highlights legal and ethical risks at the intersection of big tech data, prediction markets and crypto platforms, raising questions about corporate data controls, employee access safeguards and how regulators will police off-platform trading based on proprietary information.
This case tests how insider trading laws apply to prediction markets and crypto-adjacent platforms, affecting legal risk for employees and compliance practices at tech firms. Outcomes could shape regulator approaches and corporate controls over confidential data and external trading activity.
