Polymarket built a $14 billion US trading business almost entirely on sports bets
Polymarket’s US prediction trade recorded about $13.7 billion in contract-face-value buying and selling within the 30 days by means of Oct. 26, with sports activities accounting for 98.2% of that turnover, in accordance with DeFi Rate’s data.
That focus leaves its American enlargement closely uncovered to the dispute over whether or not sports activities occasion contracts fall underneath federal derivatives oversight or state playing legal guidelines.
The figures coincide with Reuters’ Oct. 27 report that the Commodity Futures Buying and selling Fee (CFTC) is once more analyzing compliance with Polymarket’s 2022 settlement limiting US entry to its offshore platform.
The report additionally examined onboarding and buyer protections on the newer US trade, citing two folks aware of the matter.
Alongside these questions sits a broader battle over who regulates prediction markets, because the CFTC introduced Oct. 27 that it had sued Utah, including to proceedings towards 9 different states.
Two measures of Polymarket’s enlargement
In a measurement from Sept. 27 to Oct. 26, DeFi Fee places Polymarket US’s face-value turnover up 78% from the previous 30 days, with sports activities supplying about $13.5 billion of the most recent whole.
The dataset counts every contract at its $1 face worth, no matter its buy worth. A contract purchased for 10 cents that pays $1 if right contributes $1 to headline quantity and 10 cents to {dollars} paid.
Face-value turnover measures one thing completely different from buying and selling quantity, and each are measures of buying and selling exercise.
The matching venue comparison exhibits how the selection of measurement modifications the steadiness between Polymarket’s two companies:
| Sept. 27-Oct. 26, 2026 | Contract-face-value turnover | {Dollars} paid |
|---|---|---|
| Polymarket US | $13.7 billion | $3.4 billion |
| Polymarket worldwide | $4.8 billion | $2.4 billion |
| US share of the 2 venues mixed | About 74% | About 59% |
The US venue leads by each measures, however its dominance is much less pronounced when contracts are weighted by the costs merchants truly paid.
Polymarket describes separate US and international platforms and says US customers are prohibited from buying and selling on the worldwide operation. The offshore-access inquiry considerations compliance with restrictions on that separate worldwide operation.
Reuters reported that the renewed inquiry consists of controls to find out prospects’ places and to promote within the US, with one supply describing scrutiny of previous controls and processes.
The historic place to begin is the CFTC’s Jan. 3, 2022 settlement, which required a $1.4 million penalty, the wind-down of noncompliant markets and an finish to the charged violations.
In July 2025, the CFTC closed earlier probes, and broader scrutiny started in June 2026.
Sports activities progress meets the state-law battle
The CFTC’s Utah announcement asserts unique federal jurisdiction over registered prediction markets. Utah’s lawyer normal alleged that Kalshi’s sports and other event contracts violate state gambling laws and seeks to cease these choices in Utah.
Utah’s enforcement case targets Kalshi, and its significance for Polymarket is dependent upon how courts resolve the federal-state jurisdictional dispute.
The NBA named Polymarket and Kalshi as preferred prediction market exchanges on Oct. 26. Individually, the CFTC and NBA announced an information-sharing memorandum centered on integrity in basketball prediction markets.
For Polymarket US, enterprise publicity is dependent upon its buying and selling combine. Broad sports-contract restrictions may have an effect on many of the current face-value turnover if that blend persists. Narrower restrictions would depend upon the particular contracts and jurisdictions coated.
Subsequent developments to look at embrace any enforcement end result from the reported inquiry, modifications to geographic entry or onboarding controls, and court docket choices defining the attain of state playing legal guidelines.
The following comparable buying and selling window may even present whether or not non-sports exercise turns into a bigger a part of the US enterprise. Its current measured turnover is overwhelmingly sports-based, leaving its capacity to maintain that exercise uncovered to the phrases underneath which these contracts stay obtainable.
