Kalshi and Polymarket US are reported live in South Carolina, including sports, even though sports betting is not legal there. No South Carolina enforcement action against either platform was found; the Attorney General has joined six multistate amicus briefs in Kalshi cases and the 41-attorney-general comment letter to the CFTC, opposing Kalshi's position that federal law overrides state gambling laws. Two private suits by 'South Carolina Gambling Recovery LLC' naming Kalshi entities, removed to federal court in 2025, are not state actions.

State regulator: South Carolina Attorney General (South Carolina has no gaming regulator). Sports betting is not legal in South Carolina, so no state agency licenses it. The Attorney General's news page (checked 2026-09-25) shows no item on Kalshi, Polymarket or prediction markets.
Polymarket US operates as a CFTC-designated contract market after Polymarket bought the CFTC-licensed exchange QCEX; Kalshi has been a designated contract market since 2020. Whether states may still apply their gambling laws to sports event contracts is being decided in the courts:
How sure is this page? Confidence: medium. Availability rests on news roundups (CBS Sports and Covers, 2026-09-24; FOX Sports, 2026-08-06) that agree, and the absence of a state action rests on the Attorney General's news page, court-record searches and two legal timelines rather than a statement by a state agency. Researched September 25, 2026; court cases in several states can change the status at any time.
