Appeals courts handle surge in prediction market legal cases

Federal appeals courts emerge as primary venue for prediction market disputes

Three weeks ago, Crypto.com's legal team made a calculation: rather than fight state enforcement action on its current terms, wait for the Ninth Circuit. That decision — to subordinate an active dispute to an appellate outcome not yet scheduled — tells you more about where the prediction market legal fight is headed than any roundtable remark by any regulator.

The pattern is now legible. Kalshi has sought federal relief from state enforcement in Washington. Crypto.com is deferring to the Ninth Circuit. Novig has filed in multiple state courts, explicitly to build a record for federal preemption. Each of these moves is oriented toward the same destination: an appellate court that can speak to the structural question that the CFTC's roundtable has not resolved, which is whether a designated contract market operating under CFTC authority can be reached by state law at all.

The CFTC roundtable produced the predictable range of opinions. Chair Selig's regulatory roadmap was praised by some and questioned by others on manipulation and self-certification. The CME's objections to Kalshi's contract design were stated publicly. None of this is binding. Self-certification means the exchange certifies compliance; the Commission can object or institute review, but the architecture still places the first-mover burden on the operator. What the roundtable confirmed is that the Commission is not moving quickly enough to preempt the appellate docket from filling in the gaps instead.

The Sixth Circuit already has Kalshi's preemption argument before it. The Ninth Circuit's ruling on Crypto.com will arrive on its own timeline. Neither court asked the CFTC for permission to shape this market. When courts move into a regulatory vacuum, they tend to stay.

The consensus read on this situation treats federal preemption as a clean win for platforms if they can get appellate courts to hold. I think that read is too clean. Federal preemption under the Supremacy Clause bars inconsistent state law — but inconsistency requires a court to determine what federal law actually requires, and on prediction markets, the CFTC has not said clearly enough what it requires. Self-certification is a process, not a standard. An appellate court ruling on preemption in the absence of a settled federal standard is not closing the question; it is opening a circuit on which the next round of litigation will run.

The self-certification gap that the CFTC's own roundtable left unresolved is not a procedural footnote. It is the condition that makes every appellate win provisional. A platform that prevails on preemption in the Sixth Circuit while the Commission's manipulation standard remains contested has won one argument in one jurisdiction. The underlying exposure does not revert.

The legal standard that applies here is whether a federal regulatory framework is sufficiently comprehensive to occupy the field and displace state authority — and under Dodd-Frank's amendments to the Commodity Exchange Act, that question turns on whether the CFTC has exercised its authority with enough specificity to leave no room for concurrent state action. On prediction markets, as of August 2026, it has not.
