Federal prosecutors say a Google security engineer traded on Polymarket using nonpublic Google search-trend data, then tried to hide the proceeds. The case adds to growing scrutiny of prediction markets and insider behavior.
A Google worker is accused of using secret company clues to guess what people were searching for online, then placing bets on a crypto betting site called Polymarket.
It is a bit like peeking at the answer key before a class quiz, then betting money on the result. Prosecutors say he used that unfair advantage to make a lot of money.
The case matters because betting markets can only be fair if everyone plays by the same rules. If someone uses secret info, it can spoil trust in the whole game.
Analysis
What prosecutors allege
U.S. officials say Michele Spagnuolo, a Google security engineer, was arrested and charged over trades tied to Google search data. According to the complaint unsealed by the U.S. Attorney's Office for the Southern District of New York, he allegedly used "material nonpublic information" to bet on which people would appear on Google’s list of most-searched individuals for 2025.
How the trades allegedly worked
The complaint says Polymarket began offering these markets last fall and that Spagnuolo used an internal Google tool to watch who was trending. Prosecutors allege he transferred about $3.8 million in USDC to a Polymarket address and traded through the username "AlphaRaccoon." One example cited in the filing says he allegedly saw D4vd trending a few hours before the account placed a bet on the rapper appearing among the most-searched individuals in late November.
Alleged concealment and charges
Officials say funds were moved from the Polymarket account into a wallet, then through a swapping service and a privacy tool before some of the money ended up at an Italian payment processor account opened with Spagnuolo's government ID. The complaint says he profited by more than about $1.2 million and then took steps to obscure the source and ownership of the proceeds. He is charged with commodities fraud, wire fraud, and money laundering.
Broader implications
CoinDesk says this is the second major arrest over insider trading on a prediction market, following an earlier case involving a U.S. Army soldier accused of betting on a raid he was part of. Google said it is working with law enforcement and that using confidential information to place bets is a serious policy breach. The case may deepen concerns about whether prediction markets can police insider information effectively as they grow.
