Polymarket & OG.com sue Arkansas days after AG hits Kalshi

Circuits are split: the Third sided with Kalshi, the Ninth & Sixth went against it.

The hit

Polymarket US & Crypto.com-owned OG.com have each sued Arkansas officials, seeking federal protection from state gambling enforcement, according to SBC Americas. The filings came days after Arkansas Attorney General Tim Griffin sued Kalshi, action the two exchanges cite as evidence they face the same threat.

Why it matters

Neither Polymarket US nor OG.com has actually been targeted by Arkansas yet. Both are asking federal judges to rule before that happens, arguing the Commodity Exchange Act gives the CFTC sole authority over their contracts. A win would block Arkansas from treating event contracts as gambling. A loss leaves both exposed to the same claims Griffin has made against Kalshi.

The record

Polymarket US filing	QCX LLC v. Griffin et al., Western District of Arkansas
OG.com filing	North American Derivatives Exchange complaint, 59 pages, Eastern District of Arkansas
Kalshi lawsuit	Filed by AG Tim Griffin in Independence County Circuit Court, alleging unlawful wagering & deceptive trade practices
VGW lawsuit	Sweepstakes casino operator sued by Griffin the same day as Kalshi
CFTC deadline	impartial-access interpretation: 30 days to cease geographic restrictions or explain why not
Appeal deadline	Kalshi’s opening brief in Eighth Circuit Iowa case due 7 December

What happens next

Both Arkansas districts sit within the Eighth Circuit, where Kalshi’s Iowa appeal already tests the same question. A ruling there could shape the Arkansas cases, though neither new filing is itself on appeal.
