The Commodity Futures Trading Commission issued an interpretation on Thursday of the rule that designated contract markets must give members and traders competitive, open, fair, and impartial access under Regulation 38.151(b).

Chairman Michael S. Selig said derivatives markets need to operate on a uniform national basis under the Commodity Exchange Act, and that geographic access restrictions undercut that. The press release says DCMs must stop domestic geographic restrictions that violate the impartial-access requirements within 30 days, or tell the Division of Market Oversight why compliance is not feasible. Within the same window, DCMs should make sure intermediaries on their markets are not blocking that access — or explain why they cannot.

The linked interpretive guidance says the Commission knows some DCMs have limited access to certain event-contract markets by a trader's location or residence. It says the CEA and Commission regulations generally do not allow a DCM to limit access based on where an otherwise eligible U.S. participant sits inside the United States.

That lands hardest on prediction-market DCMs that geo-blocked sports or other event contracts after state court fights. Deadspin read the release as putting venues such as Kalshi between federal impartial-access pressure and state orders that still require geo-blocks in places like Michigan, with a path to file an explanation instead of lifting a block overnight.

The Commission said it will look at facts and circumstances in any particular case. The interpretation is Commission-level guidance on Regulation 38.151(b), not a new statute.
