Sports trading reaches $468 million as Kalshi leads platform volumes

DeFi Rate counts Kalshi at 253 million dollars of the 24-hour sports total, followed by Polymarket US at 103 million dollars and Polymarket at 54 million dollars. Sports open interest across Kalshi and Polymarket US stands at 609 million dollars.

Sports prediction markets recorded $468 million in trading over 24 hours, an increase of 14%, according to DeFi Rate. The figures were reported on Nov 5, 2026, at 2:45 PM ET.

Kalshi accounts for the largest reported volume

DeFi Rate counted $253 million in sports trading on Kalshi during the period. Polymarket US followed with $103 million, while Polymarket recorded $54 million.

Those platform figures sit within the reported $468 million sports total. The supplied summary does not identify the sources of the remaining volume.

Jacksonville–Baltimore spread tops individual markets

The Jacksonville against Baltimore spread on Kalshi was the most-traded sports market, with $827,000 in volume, according to DeFi Rate.

Sports open interest across Kalshi and Polymarket US stood at $609 million. That figure covers those two platforms, rather than the full set included in the reported trading volumes.

What it means for prediction markets

  • The 14% increase marks higher aggregate sports trading activity, but the supplied figures do not show changes in individual contract prices or implied probabilities.
  • Kalshi led the named platforms by volume, while the Jacksonville–Baltimore spread provided the leading individual-market figure.
  • The $609 million open-interest total has a narrower platform scope than the headline volume figure; the two measures should not be treated as covering identical markets.
