Kalshi accounts for most early November trading as volume reaches $580 million

DeFi Rate's volume tracker shows November 1 trading so far at 580 million dollars across nine venues, with Kalshi at 543 million dollars, Polymarket at 32 million dollars and Polymarket US at 4.3 million dollars. October 31 closed at 5.75 billion dollars across all venues.

According to DeFi Rate’s volume tracker, prediction-market trading totaled 580 million dollars across nine venues so far on November 1. Kalshi accounted for 543 million dollars of that activity.

The figures were published on Nov 1, 2026 at 12:30 AM ET, making them an early snapshot rather than a completed daily total.

Volume concentrated at Kalshi

Polymarket recorded 32 million dollars, while Polymarket US registered 4.3 million dollars, according to DeFi Rate. The tracker listed the two venues separately.

Kalshi’s reported volume exceeded those of Polymarket and Polymarket US combined. The supplied summary did not provide individual figures for the remaining venues.

Prior day provides a full-session reference

October 31 finished with 5.75 billion dollars in trading across all venues, according to DeFi Rate. That completed-day figure provides context for the November 1 tally, but the different reporting windows prevent a like-for-like daily comparison.

What it means for prediction markets

  • Venue concentration: Kalshi accounted for most of the trading captured in the early November 1 snapshot.
  • Timing matters: The 580 million dollars recorded so far should not be treated as November 1’s final volume or as evidence of a full-day decline from October 31.
  • Scope is limited: These aggregate volume figures do not establish how trading was distributed across individual contracts or what probabilities markets assigned to their outcomes.
