Wall Street banks restrict staff trading on prediction markets
Goldman Sachs bars employees from prediction-market contracts tied to its business and other areas where conflicts could arise, according to people familiar with its policy. Morgan Stanley, JPMorgan Chase and Bank of America have also added or clarified guidance, while federal authorities have brought an insider-trading case involving a Google employee’s Polymarket trades.
Banks’ policy changes extend employee compliance controls to prediction-market contracts and confidential information.
