   Federal judge in Illinois finds Kalshi sports contracts likely swaps, partially blocks state licensing rules

   Judge Martha Pacold (N.D. Ill.) on October 2 partially granted preliminary injunctions sought by Kalshi, Coinbase and the CFTC, finding Kalshi's sports event contracts likely qualify as swaps under the Commodity Exchange Act and that Illinois's licensing requirements and related criminal provisions are likely preempted. The order is not a final judgment. It places the Northern District of Illinois against the Sixth and Ninth Circuits and adds weight to the case for Supreme Court review.

   Sia's Take

   This action by the Northern District of Illinois is in direct contradiction to rulings by the Sixth and Ninth Circuit courts. While this ruling will most likely have limited impact on the daily operation of prediction markets, it is yet another example of a divergent federal ruling.

   Ohio Casino Control Commission sends cease-and-desist notices to 10 prediction-market operators

   The Ohio Casino Control Commission directed Polymarket, Coinbase, Robinhood Derivatives, Webull, Novig, Underdog, ProphetX, Gemini Titan, Plus500US and Moomoo Financial to stop offering sports event contracts in Ohio by October 16, warning of civil penalties. The notices follow the Sixth Circuit's September 25 ruling against Kalshi.

   Sia's Take

   Operators with Ohio exposure now face a near-term decision between geofencing and litigating while they wait for a Supreme Court decision on this matter in the next Court term.

   CFTC sends two swap-definition rules on event contracts to White House OIRA

   The CFTC submitted a proposed rule, "Further Definition of 'Swap' to Include Event Contracts" (RIN 3038-AF82), and an interim final rule, "Further Definition of 'Swap' to Exclude Casino-Style Gambling Products" (RIN 3038-AF81), to OIRA for review. Text has not been published.

   Sia's Take

   If issued, these rules would be the CFTC's clearest statement of exclusive jurisdiction over event contracts, which compliance teams should expect states to challenge.

   Polymarket sues in The Hague to overturn Dutch gambling ban

   Polymarket is challenging the Dutch gambling authority Ksa's January 20 ban and a May penalty of €420,000, arguing its event contracts are financial products rather than bets. Ksa maintains that prediction markets offer bets not permitted under Dutch law. The case is an early test of whether a derivatives characterization holds up outside the US.

   Sia's Take

   This is a major action by Polymarket to have their designation as a gambling platform changed in the eyes of a major European regulator. If the Dutch courts rule in favor of Polymarket this action could potentially open the floodgate for other prediction market operators to be designated as swaps dealers in both the Dutch and other European jurisdictions.

   Rep. Don Davis introduces bill barring federal candidates from trading their own election contracts

   The No Betting on Your Own Race Act would bar federal candidates, spouses, dependent children and campaign committees from buying, selling or holding contracts tied to their own election, with civil penalties. It adds to congressional activity on insider trading in election markets. Operators listing political contracts should watch for any related surveillance or reporting expectations.

   Sia's Take

   This proposed legislation adds swaps related to election markets to congressional activity on insider trading. Operators listing political contracts should watch for any related surveillance or reporting expectations.
