Sports prediction markets generated 405 million dollars in trading over the last 24 hours, a decline of 24 percent from the preceding 24 hours, according to DeFi Rate.

The figures were current as of 5:30 a.m. ET on November 4. The report was published on Nov 4, 2026, at 7:30 AM ET.

Kalshi tops the reported platforms

Kalshi recorded 212 million dollars in sports trading volume, placing it ahead of Polymarket US at 74 million dollars and Polymarket at 53 million dollars, according to DeFi Rate.

The aggregate covered seven platforms: Kalshi, Polymarket US, Polymarket, Novig, Rothera, DraftKings Predictions and Underdog Exchange. The supplied summary did not provide individual volumes for the latter four platforms or explain the daily decline.

What it means for prediction markets

  • The 24 percent decline measures trading activity across the covered platforms, not a change in the implied probability of any sports outcome.
  • Kalshi accounted for more than half of the reported total, making it the largest contributor in this snapshot.
  • Polymarket US and Polymarket were reported separately. The summary provides no platform-level changes against the previous 24 hours, limiting conclusions about which venues drove the overall contraction.
