It was a quiet weekend after Friday's Missouri filings, the notable detail of which is who did not sue, namely, Kalshi, Polymarket and Robinhood, who all held off while Crypto.com and Novig went to federal court. Kalshi is separately pressing for a full Sixth Circuit review of the Ohio ruling.

Crypto.com and Novig sue Missouri; Kalshi, Polymarket and Robinhood hold off
The Block reported on October 18 that Crypto.com and Novig challenged Missouri's sports event contract cease-and-desist orders in federal court, while Kalshi, Polymarket and Robinhood did not file. Operators not litigating face the choice the Missouri Attorney General set out: stop offering the contracts in the state or apply for a Missouri Gaming Commission license.
The BlockSia's Take
Despite their vocal opposition to state-level gaming licensure, major operators like Kalshi and Polymarket appear to be adopting a passive strategy. Rather than initiating proactive legal challenges against state regulators in the near term, they seem to be banking on a favorable Supreme Court ruling to resolve the federal preemption conflict next year.
