Most Americans surveyed opposed using prediction markets to bet on U.S. elections and government actions, including 69% of Democrats and 61% of Republicans who rejected election-result wagers. The Reuters/Ipsos survey of 4,506 adults was conducted from Sept. 30 to Oct. 5. Prediction-market operators including Polymarket and Kalshi offer contracts tied to elections, government policy moves and sporting events, prompting lawsuits and disputes between state and federal authorities over regulatory jurisdiction. The poll measures public attitudes and does not establish why respondents oppose election betting or indicate that any platform or regulator changed its approach as a result.
