Kalshi dominates prediction trading as nine venues reach $126.0 billion

DeFi Rate reports 126.0 billion dollars in contracts traded over the last 30 days across nine prediction market venues, with Kalshi handling 76 percent of it. Its tracker shows 5.50 billion dollars traded so far on November 1, including 4.59 billion dollars on Kalshi and 536 million dollars on Polymarket US.

Prediction-market contracts totaling $126.0 billion changed hands across nine venues over the last 30 days, according to DeFi Rate. Kalshi accounted for 76 percent of that volume.

The figures show a substantial concentration of trading on one venue. The remaining share was spread across the other eight markets covered by the tracker.

November 1 activity

DeFi Rate’s tracker recorded $5.50 billion in trading so far on November 1, including $4.59 billion on Kalshi and $536 million on Polymarket US.

Those figures were reported in an update published November 1, 2026, at 10:30 PM ET. The November 1 total is a partial-day reading, rather than a completed daily tally.

What it means for prediction markets

  • Venue concentration matters: Kalshi’s 76 percent share means the aggregate 30-day volume largely reflects activity on that platform.
  • Coverage has limits: The $126.0 billion total covers nine venues tracked by DeFi Rate, not necessarily every prediction market.
  • Volume is not a probability signal: The supplied figures describe trading activity; they do not establish how expectations shifted for any individual contract.
