Is Polymarket Just Sports Betting? 84.5% of Its Money on an NFL Sunday
84.5%Sports and esports share of Polymarket's dollars, Sunday 27 September 2026
95% interval 83.1% to 85.8% of about $92 million; 83.8% of 176.1 million contracts across 7,683 events, 24 hours to 20:39 UTC
On Sunday 27 September 2026 sports and esports took 84.5% of the dollars traded on Polymarket and 83.8% of the contracts. Over sixteen months the dollar share ran from 31% to a low of 22% and up to 46%, and NFL Sundays sat about twenty points above weekdays. Read again the day after an NFL Sunday, in the 24 hours to 22:59 UTC on Monday 19 October 2026, the share was 58.0% of contracts. This is one Sunday, one Monday and a monthly series. The Sunday shows how far sport can go; the series shows how much of the money it usually is. The page measures what is traded, not how a contract is classified in law. That question is in the courts, set out in Is Polymarket legal in the US? and case by case in the prediction-market lawsuit tracker.
Observed 2026-09-26T20:39Z to 2026-09-27T20:39Z, population: 7,683 Polymarket events with 24-hour volume.
