Polymarket
Polymarket is a prediction‑market exchange. In the 30 days through Oct. 26, 2026, its US platform recorded $13.7 billion in contract face‑value trading, 98.2 % of which was sports. The $3.4 billion paid for contracts generated that face‑value, and volume grew 78 % from the prior month. A CFTC probe reopened on Oct. 27 to examine compliance with Polymarket’s 2022 settlement limiting US access to its offshore platform. The NBA named Polymarket its preferred exchange for NBA‑related markets on Oct. 26. Polymarket has been referred at least two cases to the CFTC and partnered with Chainalysis for market‑surveillance tools as of Apr. 2026.
