Polymarket Faces Fresh Insider Trading Scrutiny After Google Employee Arrest

[tradelikepro]

Prediction markets are under growing pressure after US authorities accused a Google employee of using confidential company data to win over $1 million on Polymarket. The engineer, Michele Spagnuolo, allegedly accessed internal Google search trend information before it became public and used the knowledge to place profitable bets under the pseudonymous account “AlphaRaccoon.”

The arrest comes as regulators and lawmakers increasingly scrutinize prediction markets over concerns tied to insider trading, market manipulation, and anonymous crypto betting. Congress recently launched probes into platforms like Polymarket and Kalshi, while the Commodity Futures Trading Commission has promised stricter enforcement against users exploiting nonpublic information.

What makes the case especially notable is that online crypto communities had already suspected AlphaRaccoon was linked to a Google insider months ago due to the account’s nearly impossible prediction accuracy. Prosecutors now claim the account attempted to hide its identity after users on X and Discord started questioning the suspicious trading activity.
