Intelligence analysis by GPT-5.4 Mini
Federal prosecutors say the Google employee traded on internal information about Google search data to profit on prediction markets. The case adds to growing scrutiny of Polymarket and insider trading in crypto-based betting markets.
A Google worker is accused of using private company info to guess something before everyone else could. He then used that secret edge to make bets and, prosecutors say, won a lot of money.
It is like looking at the answer key before a classroom quiz and then betting on the results. That is not fair to everyone else who is guessing without help.
The story matters because it shows that online betting markets can be watched and investigated, especially when someone may have used private data to cheat.
Analysis
What happened
Federal prosecutors allege that Michele Spagnuolo, a Google security engineer based in Zurich, used confidential internal Google data to trade on Polymarket from about October 2025 through December 2025. He was arrested in New York and charged with commodities fraud, wire fraud, and money laundering.
According to the complaint, one of the trades brought him about $1.2 million. The wager concerned who Google’s most-searched person of the year would be in 2025, and the complaint says he correctly predicted D4vd would win. The FBI says he knew the outcome before the public because he had accessed Google’s confidential, commercially valuable internal data.
Why it matters
The article frames this as a rare US arrest tied to alleged insider activity on a prediction market. WIRED says it is the second known US arrest involving illicit activity on prediction markets, after an April case involving a US Army special forces officer.
The story also places Polymarket under sharper regulatory and political scrutiny. House Oversight chair James Comer recently opened an inquiry into insider trading on prediction market platforms and asked Polymarket how it vets customers. Polymarket says it cooperated with prosecutors and the CFTC, and the company says its blockchain-based system leaves a traceable record. Google said the employee was placed on leave and that using confidential information to place bets was a serious policy breach.
