A quiet Sunday with little new primary-source news, so this issue carries the week's most consequential items still in play. The CFTC is pushing event-contract rulemaking toward the White House as the Sixth Circuit's ruling widens the appellate split. Operators should watch Missouri's mid-October compliance deadline and the CFTC's response to Kalshi's margin filing.

CFTC sends two event-contract proposals to the White House, one defining event contracts as swaps and one excluding casino-style products
Reports describe two proposals sent to OIRA for review: one would define event contracts as swaps, the other would exclude casino-style gambling products. The move follows two appellate losses on preemption and would give the CFTC a rulemaking basis for its jurisdiction argument. Operators should treat contract design as the compliance line, since the exclusion is aimed at casino-style structures.

Sixth Circuit rules Ohio and Tennessee may apply gambling laws to Kalshi sports contracts
The panel, with Judge Julia Smith Gibbons writing, held Kalshi had not shown its sports-event contracts are swaps under the Commodity Exchange Act, and that the Act would not preempt the state laws even if they were. The ruling deepens the split with the Ninth Circuit's decision last month and points toward Supreme Court review. Multi-state operators should plan for continued state enforcement exposure.

Kalshi Klear asks the CFTC to approve margin trading for institutional members
The September 22 filing under CFTC Regulation 40.5 seeks a 24-hour margin period of risk for qualifying products, limited to self-clearing institutional members and excluding sports, culture and mention markets. Kalshi targets 99 percent per-side confidence, above the minimum in Rule 39.13(g)(2)(iii). If the 45-day review passes without objection, leverage on event contracts becomes available to institutions.

Missouri attorney general orders six prediction market operators to stop offering sports event contracts
Attorney General Catherine Hanaway sent cease-and-desist letters on September 18 to Polymarket, Kalshi, Crypto.com, Novig, Underdog and Robinhood, giving them 30 days to comply. That puts the compliance deadline in mid-October. Operators should expect a decision point on Missouri geofencing before then.
