According to @rovercrc, the CFTC has given Polymarket approval to go live in the United States, as stated in a post on X dated September 3, 2025, which does not include an official CFTC order or press release link for independent verification, making confirmation pending at this time, source: @rovercrc on X, 2025-09-03. Polymarket previously settled CFTC charges in January 2022, paid a $1.4 million civil monetary penalty, and restricted access for U.S. users, establishing that formal CFTC actions dictate the platform’s U.S. market permissions, source: CFTC press release PR 8485-22, 2022-01-03. Trading impact will depend on the exact terms of any official CFTC action, including which event contracts are permitted, KYC and AML requirements, and geographic eligibility, none of which are specified in the cited post, source: CFTC regulatory framework and @rovercrc on X, 2025-09-03. Polymarket transactions are settled in USDC on Polygon, so any verified expansion of U.S. accessibility would affect on-chain volume, gas usage, and USDC liquidity on that network, but such effects should only be considered after an official CFTC release or Polymarket announcement is published, source: Polymarket platform documentation and prior platform operations; CFTC.gov official releases.
