Kalshi dominates prediction trading as monthly contract volume reaches $124.0 billion
DeFi Rate totals 124.0 billion dollars in contracts traded over 30 days across nine venues, with Kalshi at 93.0 billion dollars, up 53 percent on the prior 30 days.
Prediction markets recorded 124.0 billion dollars in contracts traded across nine venues over the last 30 days, according to DeFi Rate. The figures were published on Oct 31, 2026, at 8:00 PM ET.
Kalshi accounted for 93.0 billion dollars of that activity, DeFi Rate said. Its trading volume increased 53 percent compared with the prior 30 days.
Trading activity concentrates at Kalshi
DeFi Rate reported Kalshi’s share at 76 percent, placing the venue well ahead of the rest of the surveyed market. The supplied summary does not break out trading volumes for the other eight venues.
The growth comparison applies specifically to Kalshi. Without a prior-period total for all nine venues, the figures do not establish how quickly the overall prediction-market sector grew.
What it means for prediction markets
- Venue concentration matters: The reported figures put most measured trading activity at Kalshi, rather than showing an evenly distributed market.
- Volume is not a probability signal: These totals describe trading activity, not changes in the odds of any particular outcome.
- The snapshot has limits: The supplied material contains no contract-level breakdown, leaving the events driving activity unidentified.
