Sports leads Polymarket turnover as open interest reaches $263.87 million

Polymarket’s 2,100 most active events encompass 57,859 markets, according to PolymarketTrader’s November 7 snapshot. Those events recorded $47.54 million in trading volume over 24 hours.

Open interest across the same events stood at $263.87 million. The figures describe the selected group of active events, rather than an explicitly platform-wide total.

Sports and politics dominate activity

Sports generated 46 percent of the 24-hour trading volume, according to PolymarketTrader. Politics and elections accounted for 37 percent.

Together, those categories represented 83 percent of turnover in the snapshot, leaving 17 percent across other categories. The summary did not provide a further breakdown.

A snapshot, not a trend

The figures were published on Nov 7, 2026, at 12:15 PM ET. They offer a point-in-time view of activity but include no prior-period comparison from which to establish whether volume or open interest was rising or falling.

The summary also does not identify individual markets or their prices. It therefore provides a view of where trading activity was concentrated, not how traders were assessing specific outcomes.

What it means for prediction markets

• Activity was concentrated: Sports and politics and elections together accounted for 83 percent of reported 24-hour volume.
• Scope matters: The $47.54 million volume and $263.87 million open-interest figures apply to the 2,100 most active events covered by the snapshot.
• Aggregate figures have limits: Without market-level prices or historical comparisons, the data cannot establish changes in implied probabilities or trading momentum.
