Kalshi leads sports contract activity as daily volume climbs 17 percent

Kalshi accounted for 276 million dollars of the sports total, followed by Polymarket US at 101 million dollars and Polymarket at 54 million dollars. Open interest on Kalshi and Polymarket US stands at 633 million dollars.

Sports prediction markets generated 495 million dollars in trading over 24 hours, a 17 percent increase from the prior day, according to DeFi Rate.

Kalshi accounts for the largest share

Kalshi contributed 276 million dollars to the sports total, putting it ahead of the other platforms identified in the summary.

Polymarket US followed with 101 million dollars, while Polymarket recorded 54 million dollars. The figures appeared in a report published Nov 7, 2026, at 12:30 PM ET.

DeFi Rate also reported 633 million dollars in combined open interest on Kalshi and Polymarket US. That figure measures outstanding positions rather than the trading activity captured by the 24-hour volume total.

What it means for prediction markets

  • The 17 percent daily increase shows higher sports trading activity, but the summary provides no longer-term comparison to establish whether that growth is sustained.
  • Kalshi accounted for more than half of the reported sports volume. The open-interest figure covers Kalshi and Polymarket US together, without a platform-by-platform breakdown.
