The bank updates policies after regulators charged a Google employee for allegedly profiting $1.2 million using nonpublic data.
Goldman Sachs has prohibited employees from trading prediction market contracts tied to the bank, elections, financial markets, and geopolitical events. The move follows concerns over insider trading risks linked to nonpublic information.
Morgan Stanley already enforces similar restrictions, while Bank of America is reportedly revising its guidelines. The policy shift comes after U.S. regulators charged a Google employee in May for allegedly using confidential data to gain $1.2 million on Polymarket.
No immediate market reaction was reported, but the update reflects broader scrutiny of prediction markets in financial institutions.
