Kalshi dominates prediction trading as monthly volume hits $132.3 billion
DeFi Rate tracks 5.2 billion dollars traded in the last 24 hours across nine venues, with Polymarket US next at 11 percent of 30-day volume. Volume so far on November 5 totals 2.31 billion dollars, led by Kalshi at 2.05 billion dollars.
Prediction markets recorded $132.3 billion in trading volume over 30 days, with Kalshi accounting for 76% of the total, according to DeFi Rate.
The figures, published Nov 5, 2026 at 1:30 PM ET, show activity heavily concentrated on one venue. Polymarket US ranked next, representing 11% of 30-day volume.
Daily activity adds to the picture
DeFi Rate tracked $5.2 billion traded across nine venues in the last 24 hours. That rolling measure covers a different period from the calendar-day figures available for November 5.
Volume so far on November 5 totaled $2.31 billion, including $2.05 billion handled by Kalshi. The partial-day figures therefore also show Kalshi accounting for most of the reported activity.
What it means for prediction markets
- Venue concentration is pronounced: Kalshi’s 76% share of 30-day volume places it well ahead of Polymarket US at 11%.
- Time windows matter: The $5.2 billion rolling 24-hour total and the $2.31 billion November 5 total are not directly comparable measures of daily activity.
- Volume offers a limited signal: The supplied figures describe trading activity, but do not establish individual contracts’ liquidity, trader counts or the accuracy of market probabilities.
