Event Summary

Michele Spagnuolo, a software engineer at Alphabet Inc., has been charged with commodities fraud, wire fraud, and money laundering for allegedly using confidential company data to make over $1.2 million through insider trading on the prediction market platform Polymarket. Spagnuolo, operating under the username 'AlphaRaccoon', placed bets on Google's most-searched persons of 2025, including D4vd, Bianca Censori, Pope Leo XVI, and Kendrick Lamar, knowing the outcomes before public release. He was arrested in New York and released on a $2.25 million bond. Alphabet Inc. has placed Michele Spagnuolo on leave and is cooperating with law enforcement, as is Polymarket, which assisted in the investigation. This case is the second of its kind brought by the U.S. attorney's office for the Southern District of New York this year, following a similar case involving Gannon Van Dyke and Nicolás Maduro.
