Goldman Sachs Bans Employees From Trading Prediction Market Contracts

The bank said violations could bring discipline, account closures or dismissal as firms face rising concerns about insider trading on event contracts.

  • Goldman Sachs has banned employees from trading prediction market contracts involving elections, financial markets, macroeconomic data, and geopolitics, according to people familiar with the matter.
  • This directive follows the first event contract insider-trading case involving a private sector company, when federal authorities charged Google employee Michele Spagnuolo with exploiting inside information to win roughly $1.2 million.
  • Under the revised policy, Goldman reserves the right to claw back gains exceeding $200 for improper trades, while Balyasny Asset Management barred all personal-account prediction market activity outright.
  • CNBC reached out to 50 publicly traded and privately held companies, finding only three have formalized prediction market policies while 36 did not respond to inquiries about their internal rules.
  • Legal experts warn that as insider trading prosecutions increase, businesses face greater pressure to implement specific policies to mitigate liability risks, according to Karen Woody, a law professor at Washington and Lee University.
