DeFi Rate counted 484 million dollars traded across sports markets on seven venues in the last 24 hours, led by Kalshi at 259 million dollars and Polymarket US at 99 million dollars. The most traded single market was 76ers against Pistons on Polymarket at 1.8 million dollars, and open interest across Kalshi and Polymarket US stood at 575 million dollars.

Sports prediction markets generated 484 million dollars in trading across seven venues over the last 24 hours, up 14 percent, according to DeFi Rate. The figures were published Nov 5, 2026, at 3:15 AM ET.

Kalshi accounts for the largest share

Kalshi led the venues with 259 million dollars in sports trading volume, according to DeFi Rate. Polymarket US followed with 99 million dollars.

The summary did not provide individual volumes for the other venues included in the seven-venue total.

Basketball matchup tops individual markets

The most actively traded single market was 76ers against Pistons on Polymarket, with 1.8 million dollars in volume, according to DeFi Rate. The summary identified that market’s venue as Polymarket, while separately naming Polymarket US in the venue-level figures.

Combined open interest at Kalshi and Polymarket US stood at 575 million dollars. That figure covers two venues, unlike the daily trading total, which spans seven.

What it means for prediction markets

  • The 14 percent increase indicates higher aggregate sports trading activity, but the supplied figures do not show how that growth was distributed across venues.
  • Kalshi’s 259 million dollars represents more than half of the reported 484 million dollars in daily volume.
  • The 575 million dollars in open interest has a narrower venue scope than the volume total; the figures should not be treated as interchangeable measures.
  • The leading individual market highlights activity around 76ers against Pistons, but no prices or implied probabilities were supplied.
