Kalshi accounts for three-quarters of tracked prediction-market contract volume

DeFi Rate's volume tracker counts 129.1 billion dollars in contracts traded across nine venues in the last 30 days, with Kalshi at 97.5 billion dollars and a 75.5 percent share. Trading on November 3 totaled 5.17 billion dollars across venues, and November 4 has reached 2.22 billion dollars so far.

Prediction markets recorded 129.1 billion dollars in contract trading across nine venues over the last 30 days, according to DeFi Rate’s volume tracker.

Kalshi accounted for 97.5 billion dollars of that total, giving it a 75.5 percent share. The figures put a substantial majority of tracked activity on one venue.

Daily totals provide a shorter-term view

Across the tracked venues, trading on November 3 totaled 5.17 billion dollars, according to DeFi Rate.

November 4 volume had reached 2.22 billion dollars so far in the update published on Nov 4, 2026, at 12:00 PM ET. That partial-day figure is not directly comparable with the completed November 3 total.

What it means for prediction markets

  • Activity is concentrated: Kalshi’s 75.5 percent share makes it the dominant venue by contract volume within the nine-venue tracker.
  • Coverage matters: The 129.1 billion dollars measures contracts traded across the venues tracked by DeFi Rate, rather than establishing a total for every prediction market.
  • The latest day remains incomplete: November 4’s running total does not yet establish whether full-day activity will exceed November 3’s 5.17 billion dollars.
