Arizona Moves to End Kalshi Sports Contract Fight While Election Markets Remain Unresolved

Arizona Is Following Nevada's Playbook Against Kalshi. Sports Contracts Lose. Elections Stay Open.

Arizona is about to ask the Ninth Circuit for something very specific, and it is borrowing the exact language another state already used to get it.

The state will ask the court to summarily vacate the district court's preliminary injunction against Arizona as it applies to sports-event contracts, based directly on the Ninth Circuit's ruling in KalshiEX, LLC v. Assad, and to remand the case for additional proceedings on election-event contracts. That is the whole request in two parts: kill the sports side of the injunction outright, send the election side back down for more work.

The Ruling Arizona Is Leaning On

The Ninth Circuit issued its decision in Assad on August 28, 2026. The case involved KalshiEX, LLC as plaintiff, North American Derivatives Exchange (doing business as Crypto(.com)| Derivatives North America) as intervenor plaintiff, and the United States along with the Commodity Futures Trading Commission as plaintiffs-appellees.

The same day the opinion came down, the defendants in that case moved quickly. They reached out to every other party involved and asked them to agree, on summary disposition, that the court should take two actions: vacate the district court's May 5, 2026 preliminary injunction order as it related to sports contracts, and remand the case for further proceedings on election contracts.

That is a telling sequence. The defendants, not Kalshi, were the ones pushing to lock in the result immediately. When the side that lost an injunction moves that fast to get a ruling formalized and applied, it is a good sign for which way the underlying decision actually broke.

Why Sports and Elections Are Being Treated Differently

Both the original Assad case and Arizona's new filing draw the same line between two categories of contracts that Kalshi offers: sports-event contracts and election-event contracts. Sports contracts are being resolved cleanly and quickly, with courts moving to vacate injunctions that had protected them. Election contracts are not getting the same treatment. Instead of a clean resolution, they are being sent back to the district court level for additional proceedings.

That split matters beyond the courtroom. It means the legal question over whether Kalshi's sports markets can be regulated by individual states is closer to settled, at least within the Ninth Circuit, while the legal status of election markets remains genuinely undecided. Two products from the same company, built on the same exchange infrastructure, are now sitting on two different legal tracks.

What Arizona's Move Actually Signals

Arizona did not wait for its own case to work through every stage of briefing and argument. It is asking the Ninth Circuit to apply the Assad outcome directly to its own dispute with Kalshi, using the same two-part structure: vacate as to sports, remand as to elections. That is not a new legal theory. It is a state recognizing that the circuit has already answered the sports-contract question and choosing not to relitigate it.

For Kalshi, that pattern is the real story here, more than any single case. One circuit ruling on sports contracts is turning into a template other states can invoke without starting from scratch. Each time a state files a request that mirrors Assad almost word for word, it becomes a little harder to argue that the sports-contract question is still open anywhere inside that circuit.

Election contracts are a different matter entirely, and Arizona's own filing treats them that way. Nobody involved in this fight, not the states and not Kalshi, is asking the Ninth Circuit to resolve that piece the easy way. It is going back to the district court, where a fuller record will have to be built before anyone gets a final answer.

That is where the real uncertainty in this space still lives. The sports side of the ledger is closing. The election side is just getting started.

Kalshi Is Fighting on Two Fronts at Once

Arizona's path to a quick win is not going unopposed. Defendants contacted all plaintiffs again on September 1 and September 2 to lay out their position on the proposed disposition, and to make clear they were prepared to file a motion under Ninth Circuit Rule 3-6 if the parties could not reach agreement. Kalshi's counsel responded on September 2: the company intends to seek rehearing in Assad itself, and on that basis will oppose Defendants' motion.

That puts Kalshi in an unusual spot. It is fighting the Assad ruling directly while also fighting the Arizona motion that depends entirely on that ruling standing. If Kalshi wins a rehearing, the ground under Arizona's request changes. If it does not, opposing the Arizona motion mainly buys time rather than a different result.

The CFTC has not staked out a position yet. Appearing as counsel for the Federal Plaintiffs, it asked for an additional week to consider Defendants' proposed disposition, a request neither Kalshi nor Crypto(.com) objected to. Defendants agreed to wait. The CFTC's answer is expected by September 11, 2026, and it carries real weight here: the agency originally sought the injunction to block criminal enforcement against Kalshi, not simply to defend a jurisdictional theory, so its read on the Arizona proposal is a read on whether that criminal-enforcement shield is still worth defending.

Once the Federal Plaintiffs respond, Defendants have committed to moving quickly, filing either an updated status report or a motion for appropriate relief promptly afterward. Arizona is not necessarily waiting on that timeline either. The state could file its own motion for summary disposition as early as this Friday, regardless of where the CFTC lands.
