Kalshi captures dominant share of $136.5 billion prediction market turnover

DeFi Rate reports 136.5 billion dollars in contracts traded over 30 days across nine venues, with Kalshi handling 76 percent of volume and 6.9 billion dollars traded in the last 24 hours.

Prediction markets recorded $136.5 billion in contract trading across nine venues over 30 days, according to DeFi Rate. Kalshi accounted for 76 percent of that volume.

The figures, reported on Nov 8, 2026 at 7:00 AM ET, show trading concentrated heavily on one platform within the nine-venue group.

Trading scale and concentration

DeFi Rate also reported $6.9 billion traded in the last 24 hours. That provides a shorter-window measure alongside the 30-day total, but the supplied summary offers no historical comparison to establish whether activity is accelerating.

The summary does not identify the other eight venues or break down trading by contract category. Its clearest finding is therefore the scale of reported turnover and Kalshi’s share, rather than which events attracted trading.

What it means for prediction markets

  • Venue concentration matters: Kalshi’s 76 percent share means the aggregate volume figure largely reflects activity on that platform, rather than an even distribution across nine venues.
  • Turnover is not a probability signal: The reported totals measure trading activity; the summary supplies no contract prices or outcomes from which to assess changes in market expectations.
