Google engineer accused of insider trading, using internal search data to arbitrage $1.2 million on Polymarket

On May 28, U.S. federal officials announced the arrest of Michele Spagnuolo, a 36-year-old Google security engineer and an Italian citizen. He was charged by the U.S. Attorney’s Office for the Southern District of New York with three counts: commodities fraud, wire fraud, and money laundering. He is alleged to have placed bets in Polymarket’s prediction markets through an account called “AlphaRaccoon,” earning more than $1.2 million in personal profits.

Allegations Confirmed in the Indictment: AlphaRaccoon Account and D4vd Bets

The indictment alleges that between October and December 2025, Spagnuolo used the AlphaRaccoon account to make 16 large bets. The wagers mainly targeted the top-search-person rankings in Google’s “2025 year-in-search” report (released on December 4, 2025). The indictment says that hours before each bet was placed, Spagnuolo accessed Google internal tools to view search-volume data for the relevant individuals.
