Google Employee Charged With Insider Trading on Polymarket A Google software engineer’s alleged $1.2 million score on the crypto prediction market Polymarket has become a test case for how traditional insider-trading rules collide with new, lightly regulated betting platforms.

Prosecutors and regulators: Polymarket as a Wall Street-style crime scene

Federal prosecutors in the Southern District of New York say staff information security engineer Michele Spagnuolo abused his access to internal Google tools that showed confidential “Year in Search 2025” data, then used that information to place “millions in bets” on Polymarket under the alias “AlphaRaccoon.” Those wagers allegedly included correctly predicting that singer d4vd would be the most searched person of 2025, at a time when market odds were “fairly slim.”

He is charged with commodities fraud, wire fraud and money laundering, with prosecutors alleging he ultimately “profited approximately $1.2 million on his Google Year in Search 2025-related bets.” The Commodity Futures Trading Commission has also filed a parallel civil case, underscoring regulators’ view that Polymarket contracts function like derivative commodities rather than harmless wagers.

Google: Policy breach, not platform problem

Google is framing the incident as a clear-cut violation of corporate rules, not a systemic failure. The company says Spagnuolo “accessed our marketing material using a tool available to all employees, but using such confidential information to place bets is a serious breach of our policies,” adding that he has been placed on leave and that Google is cooperating with law enforcement.

Polymarket: Compliance showcase amid growing scrutiny

Polymarket, by contrast, is emphasizing its cooperation and presenting itself as a willing partner in enforcement, noting it “worked closely with the U.S. Attorney’s Office for the Southern District of New York and the CFTC, and is the only prediction platform to date whose cooperation has led to insider trading charges in the United States.”

The contrasting messages reveal the emerging regulatory fault line: prosecutors and regulators are treating prediction markets as financial infrastructure subject to insider-trading norms, while Google and Polymarket both argue the real threat lies not in the platform’s existence, but in how insiders exploit access to information that was never meant to leave the corporate firewall.
