Goldman Sachs restricts employee trading on prediction markets citing insider trading risks, following SEC charges against a Google employee.
Regulation & Gov ·
A U.S. regulatory action against a Google employee for alleged insider trading on prediction markets has sparked a wave of policy updates across major financial firms. The employee was charged in May after reportedly using confidential information to generate roughly $1.2 million in profits on Polymarket contracts, according to CNBC reporting.
The enforcement action has prompted Goldman Sachs to implement trading restrictions on its workforce, banning transactions in contracts tied to the bank's own operations, elections, financial markets, macroeconomic data releases, and geopolitical events. Morgan Stanley maintains existing safeguards, while Bank of America is in the process of tightening its employee trading guidelines in response to the same regulatory concerns.
What remains unclear is how broadly these restrictions will spread across the financial services sector, whether regulators plan additional enforcement actions beyond the Google case, and what specific mechanisms firms will use to monitor compliance with these new policies. The enforcement pattern suggests regulators view prediction markets as a material vector for insider trading risk, but the full scope of regulatory intent is not yet defined.
