Arkansas faces two new prediction-market lawsuits after Kalshi fight

OG’s 59-page suit comes even though Arkansas has not taken enforcement action against OG itself, according to SBC Americas.

The hit

Polymarket US & Crypto.com-owned OG.com have sued Arkansas officials in federal court. Both filed Monday, pointing to Attorney General Tim Griffin’s lawsuit against Kalshi as proof they face the same threat, & are asking judges to intervene before similar action reaches them, according to SBC Americas.

Why it matters

The filings turn a single-exchange enforcement fight into a wider jurisdictional battle over who regulates event contracts. Polymarket’s QCX LLC & OG’s operator, North American Derivatives Exchange, argue the Commodity Exchange Act gives the CFTC sole authority, blocking Arkansas’s gambling regime. Neither Polymarket US nor OG has itself been targeted by Arkansas enforcement.

The record

Polymarket suit	QCX LLC v. Griffin et al., filed in the Western District of Arkansas
OG.com suit	Filed in the Eastern District of Arkansas, names AG Griffin & 7 state racing commission members
Kalshi case that triggered it	Arkansas sued KalshiEX LLC & Kalshi Inc. in Independence County Circuit Court last week
CFTC deadline	Exchanges given 30 days to address geographic access restrictions, per the agency’s impartial-access interpretation
Appeal deadline	Kalshi’s Eighth Circuit opening brief in KalshiEX LLC v. Bird due 7 December

What happens next

Both new Arkansas districts sit within the Eighth Circuit, where Kalshi’s Iowa appeal is already pending. A ruling there could shape, but will not automatically settle, the new Polymarket & OG cases.
