Polymarket US election trading lifts monthly volume to $14.9 billion
DeFi Rate reports Polymarket US traded 479 million dollars in contracts on November 3, with 119 million dollars paid across 399,000 trades, taking its 30-day total from October 5 to November 3 to 14.9 billion dollars, up 50 percent from the prior 30 days. The venue held a 12 percent share of prediction-market volume over the window, and November 3 reached 59 percent of its record day of 811 million dollars on October 24.
Polymarket US recorded $479 million in contract trading on Election Day, November 3, according to DeFi Rate. That brought its volume for the 30 days from October 5 to November 3 to $14.9 billion.
The figures, published on Nov 4, 2026, at 8:15 AM ET, put that rolling total 50 percent above the previous 30-day period.
Election Day activity below the record
DeFi Rate reported $119 million paid across 399,000 trades on November 3. The payment figure is separate from the reported $479 million in contract trading volume.
Despite the election timing, November 3 did not set a daily volume record. Its activity reached 59 percent of the venue’s $811 million peak on October 24, according to DeFi Rate.
Share of the broader market
Polymarket US accounted for 12 percent of prediction-market volume over the October 5–November 3 window, DeFi Rate reported. That places its monthly growth alongside a measure of its participation in the broader market.
The supplied figures do not include a prior-period market share or a breakdown by contract. They therefore establish growth in overall venue activity, but not whether Polymarket US gained share or which markets drove the increase.
What it means for prediction markets
- Activity increased over the monthly window: The $14.9 billion total was up 50 percent from the preceding 30 days, rather than reflecting only Election Day trading.
- Election Day was not the high-water mark: November 3 volume remained below the October 24 record, reaching 59 percent of that peak.
- Volume is not a probability signal: These aggregate figures describe trading activity and market share; they do not show changes in the implied likelihood of any particular outcome.
