Sports contract turnover falls 22 percent across seven prediction venues

DeFi Rate totals trading on Kalshi, Polymarket US, Polymarket, Novig, Rothera, DraftKings Predictions and Underdog Exchange. The board covers NBA, NFL, NHL, UFC and other sports contracts priced through the evening of November 4.

Sports prediction markets recorded 415 million dollars in trading over 24 hours, down 22 percent from the day before, according to DeFi Rate. The total spans seven venues rather than a single exchange.

Scope of the trading snapshot

DeFi Rate’s tally includes Kalshi, Polymarket US, Polymarket, Novig, Rothera, DraftKings Predictions and Underdog Exchange. Polymarket US and Polymarket are listed separately in that coverage.

The board encompasses NBA, NFL, NHL, UFC and other sports contracts, with pricing captured through the evening of November 4. The report was published on Nov 4, 2026, at 7:15 PM ET.

The supplied summary gives no venue-level or sport-level breakdown. It therefore does not establish which markets contributed most to the decline, or whether trading fell across all seven venues.

What it means for prediction markets

  • The 22 percent decline measures aggregate trading activity, not a change in the implied probability of any sporting outcome.
  • The 415 million dollars total provides a cross-venue snapshot; the supplied figures do not establish any individual platform’s share.
  • With only a comparison to the day before, the summary does not establish a sustained trend in sports-contract trading.
