Summary
The U.S. Department of Justice and the Commodity Futures Trading Commission charged Michele Spagnuolo, a Google software engineer and Switzerland resident, with insider trading on May 27, 2026. According to the CFTC complaint filed in the U.S. District Court for the Southern District of New York, Spagnuolo traded on Polymarket.com using sensitive nonpublic information regarding Google's official Year in Search list for 2025. The alleged scheme generated more than $1 million in unlawful profits.
As a software engineer at Google, Spagnuolo had access to confidential business information about the Year in Search results before their official public release. The complaint alleges he misappropriated this information to trade event contracts on Polymarket, capitalizing on knowledge unavailable to other market participants. This represents the first prediction-market insider-trading charge brought against an employee of a public company, marking a significant escalation in regulatory enforcement within the emerging prediction markets sector.
The CFTC's enforcement action seeks comprehensive remedies, including disgorgement of all ill-gotten gains, restitution to injured parties, civil monetary penalties, permanent bans on trading and registration in CFTC-regulated markets, and permanent injunctive relief against further violations of the Commodity Exchange Act and CFTC regulations. CFTC Chairman Michael S. Selig stated: "The Commission will not tolerate fraud, manipulation, or insider trading, regardless of the technology or platform that is used." Director of Enforcement David I. Miller emphasized that "Employees who are entrusted with confidential business information cannot misappropriate that information for personal financial gain" and reaffirmed the Division's commitment to policing insider trading across CFTC-regulated markets.
This enforcement action reflects intensified regulatory scrutiny of prediction markets following the CFTC's February 2026 advisory on insider trading in prediction markets. The case signals that traditional insider trading prohibitions extend fully to decentralized prediction platforms and that regulators view market integrity violations on these platforms with the same severity as violations in traditional futures and derivatives markets. The action is likely to trigger broader compliance reviews among technology employees and other insiders with access to material nonpublic information at companies trading-related events on prediction platforms.
