Kalshi leads sports market activity as daily volume rises sharply

DeFi Rate reported sports markets traded 702 million dollars across Kalshi, Polymarket US, Polymarket, Novig, DraftKings Predictions, Rothera and Underdog Exchange in the last 24 hours, up 46 percent from the prior 24 hours, with Kalshi at 401 million dollars. Open interest stood at 629 million dollars on Kalshi and Polymarket US.

Sports prediction markets recorded 702 million dollars in trading over the last 24 hours, an increase of 46 percent from the prior 24 hours, according to DeFi Rate.

The figures were reported on Nov 1, 2026, at 7:45 AM ET, providing a snapshot of activity across seven platforms.

Kalshi accounts for the largest share

The volume total covered Kalshi, Polymarket US, Polymarket, Novig, DraftKings Predictions, Rothera and Underdog Exchange. Kalshi contributed 401 million dollars, more than half of the combined trading volume.

Separately, DeFi Rate put open interest at 629 million dollars across Kalshi and Polymarket US. That figure covers only those two platforms, rather than the seven included in the trading-volume total.

What it means for prediction markets

  • The 46 percent increase signals a substantial rise in sports trading activity over the preceding 24-hour period, but the supplied figures do not establish a longer-term trend.
  • Kalshi’s 401 million dollars in volume places it at the center of the reported activity. Individual volume figures for the other six platforms were not supplied.
  • The 629 million dollars in open interest and 702 million dollars in trading volume measure different things and cover different groups of platforms; they should not be treated as directly comparable totals.
