Event contracts, the exchanges that list them, and the running dispute between federal derivatives regulation and state gambling law over who is in charge.
A second unanimous panel in three weeks has ruled against the exchange, this time for two California tribes under the Indian Gaming Regulatory Act.

The federal regulator moved for a preliminary injunction on 11 September, with Robinhood pressing to join the case and Crypto.com taking the Nevada question to the Supreme Court. Connecticut's responses are due on 2 October.
