Polymarket US logged about $8.7 billion in contract volume in September 2026, while sports made up 99.4% of trading since launch at the U.S.-regulated event-contract venue. The September volume figure counts contracts at their $1 payout value, rather than the price traders paid to acquire them. It measures contract activity, not the cash traders spent. Sports contracts accounted for 99.4% of Polymarket US volume over the venue’s operating history. Combination contracts, which bundle multiple outcomes, represented more than half of U.S. volume in the final full week of September.
