Goldman Sachs has restricted employees from trading prediction market contracts linked to politics, companies and financial markets, adding to concerns about conflicts of interest and the potential use of non-public information across the expanding sector.
The Wall Street bank will continue to permit staff participation in sports and entertainment markets, but repeated breaches of the wider restrictions could result in disciplinary action.
Other financial institutions are also reviewing or clarifying their policies as platforms including Kalshi and Polymarket attract greater volumes across contracts tied to elections, economic indicators, company performance and geopolitical events.
The controls reflect a growing compliance challenge for banks whose employees may have access to confidential corporate, economic or government information capable of influencing the outcome or pricing of an event contract.
The development has also renewed debate over whether prediction markets should be treated primarily as financial instruments, forecasting tools or gambling products.
Anna Pavlova, Professor of Finance at London Business School, said Goldman’s decision highlighted an increasingly blurred boundary between investing, speculation and gambling.
Writing in the Financial Times, Pavlova argued that prediction markets formed part of a wider trend already visible in retail trading, where products such as options and leveraged exchange traded funds have become increasingly accessible to less experienced participants.
She said the appeal of prediction markets could be driven as much by competition, instant feedback and game like engagement as by conventional investment fundamentals.
Goldman’s distinction between contract categories is particularly relevant to the gambling sector. Sports and entertainment markets remain permitted, while contracts tied to politics, companies and financial developments face tighter internal controls. This approach suggests prediction markets may ultimately require different compliance and regulatory treatment according to the subject of each contract and the information available to potential participants.
Sports markets raise familiar questions around betting integrity, age restrictions and state gaming authority. Political and financial contracts create additional concerns around insider information, market manipulation and conflicts involving employees of banks, governments and major companies.
Prediction platforms argue that event contracts aggregate information and provide useful forecasts. Their expansion into sport, politics and breaking news has nevertheless produced a consumer experience increasingly similar to gambling, with binary outcomes, rapid settlement and the possibility of short-term financial losses.
As the sector grows, internal restrictions imposed by major financial institutions are developing faster than a settled legal distinction between investment and betting. Goldman’s policy indicates that, whatever classification regulators eventually adopt, prediction markets are already being treated as a material compliance risk by some of the organisations closest to financial markets.
