Kalshi accounts for most of November 1 prediction market volume

Prediction-market trading totaled 1.64 billion dollars so far on November 1, 2026, across nine venues, according to DeFi Rate’s volume tracker. Kalshi accounted for 1.42 billion dollars of that total.

The figures were reported at 6:45 AM ET on November 1, 2026. They represent activity recorded so far that day, rather than a completed daily total.

Volume concentrated at Kalshi

Among the other venues identified in the summary, Polymarket US recorded 89 million dollars, Polymarket recorded 60 million dollars and DraftKings Predictions recorded 45 million dollars, according to DeFi Rate.

Kalshi’s reported volume substantially exceeded each of those figures. The summary did not provide individual totals for the remaining venues included in the nine-venue tracker.

What the tracker measures

DeFi Rate counts contracts at their 1 dollar face value. That convention is important when interpreting the dollar totals: the reported measure values contracts at face value rather than stating how much traders paid for them.

What it means for prediction markets

• Venue concentration: Kalshi accounted for most of the reported activity, making the aggregate heavily dependent on its volume.
• Measurement matters: The 1 dollar face-value convention should remain explicit when comparing these figures with volume measures elsewhere.
• Timing limits the snapshot: The 6:45 AM ET report captures only trading so far on November 1, not the full day’s activity.
