Google engineer Michele Spagnuolo faces federal fraud charges for using inside data to win $1.2M on Polymarket prediction contracts.
A 36-year-old Google software engineer named Michele Spagnuolo has been arrested and hit with federal criminal charges after allegedly exploiting confidential company metrics to generate over $1.2 million in illegal profits on the decentralized prediction marketplace Polymarket. The unsealing of the criminal complaint on May 27, 2026, by the U.S. Attorney’s Office for the Southern District of New York marks a historic legal milestone, establishing one of the first federal insider trading prosecutions targeting a decentralized web3 betting application. According to the formal indictment, Spagnuolo, an Italian citizen residing in Switzerland, was taken into federal custody in New York on Wednesday morning and subsequently released on a $2.25 million bond following an aggressive joint investigation spearheaded by the Federal Bureau of Investigation and the Commodity Futures Trading Commission.
The high-stakes legal drama unfolds around a series of highly specific digital wagers placed on Polymarket between October 15, 2025, and December 4, 2025. Federal prosecutors reveal that Spagnuolo manipulated the platform using an anonymous trading alias known as “AlphaRaccoon” to systematically bet a total of $2.75 million on highly volatile prediction contracts tied directly to Google’s highly anticipated, non-public “2025 Year in Search” metrics. The targeted betting pools allowed crypto traders to speculate on cultural statistics, such as who would rank as the absolute number-one searched person on Google or place within the top five most searched individuals globally for the calendar year.
The core motivation behind the illicit scheme was basic financial greed fueled by a massive, asymmetric information advantage. As a tenured software engineer at Google since 2014, Spagnuolo possessed direct backend permissions to query an internal data tool displaying real-time global search trends before they were curated and broadcast to the public. Court filings obtained by Crypto Briefing show that after accessing this internal system, the engineer noted that the musician d4vd had overtaken Kendrick Lamar as the year’s top trending personality. Armed with this definitive corporate secret, Spagnuolo immediately utilized his “AlphaRaccoon” profile to place aggressive, highly accurate bets on d4vd at a time when the broader trading public viewed the outcome as statistically improbable.
Once Google officially released its public data report on December 4, 2025, the underlying prediction markets resolved favorably, immediately netting the engineer’s digital wallet more than $1.2 million in clear profit. According to an extensive report by TechCrunch, U.S. Attorney Jay Clayton emphasized that the federal government is heavily prioritizing prediction market manipulations, noting that corporate insiders cannot hide behind the perceived anonymity of blockchain systems to break the law. Following the arrest, a spokesperson for Polymarket confirmed that the company actively cooperated with law enforcement, making it the first prediction platform to actively aid federal prosecutors in securing insider trading charges. Google has since corporate-distanced itself from the situation, confirming that the engineer has been placed on an indefinite administrative leave pending immediate termination. Spagnuolo now faces multiple severe felony counts, including wire fraud, commodities fraud, and money laundering, which collectively carry a maximum statutory penalty of up to 20 years in federal prison.
