Prediction market turnover hits $6.1 billion as Senate prices diverge

DeFi Rate puts total prediction market volume at 6.1 billion dollars over the last 24 hours across nine exchanges, counting contracts at one dollar each. Its comparison board also shows Polymarket pricing a Democratic Senate outcome 1.5 points higher than Kalshi.

Prediction markets recorded $6.1 billion in volume over the last 24 hours across nine exchanges, according to DeFi Rate. The total counts contracts at $1 each.

The snapshot, published Nov 1, 2026 at 11:15 AM ET, brings together activity across those exchanges. The supplied summary does not break down the total by venue or contract.

Senate pricing differs across platforms

DeFi Rate’s comparison board also shows Polymarket pricing a Democratic Senate outcome 1.5 points higher than Kalshi. That puts the same broad political outcome at different price levels on the two platforms.

The summary provides neither platform’s absolute price nor the full contract terms. It therefore establishes the reported gap, but not whether differences in settlement criteria or other contract details affect the comparison.

What it means for prediction markets

  • Volume needs its accounting context: The $6.1 billion figure uses a $1-per-contract convention; it should not be read as a separate measure of cash committed.
  • Venue prices are not uniform: The reported 1.5-point spread places Polymarket above Kalshi for a Democratic Senate outcome.
  • The snapshot has limits: Without venue-level volume, absolute prices or contract terms, the summary cannot establish where activity is concentrated or explain the pricing difference.
