Trump's commodities regulator closes Polymarket betting probe

The Commodity Futures Trading Commission issued a formal declination notice to Polymarket in early July 2025, closing its civil investigation of the prediction betting platform with no further action taken. The probe had examined whether Polymarket continued to accept bets from U.S. users despite assurances made in 2022 following a $1.4 million CFTC fine for failing to register as a facility for event-based binary options. The closure is consistent with a broader pattern of the Trump administration dropping Biden-era enforcement actions against crypto and prediction market companies, including the CFTC's May 2025 decision to drop its appeal in the KalshiEx election betting case.
