Kalshi tells Washington court Crypto.com gets rules Kalshi cannot

On Monday, Kalshi sent an email to its Washington state customers that began: "The Washington state government has blocked your right to trade freely on Kalshi." The language was deliberate. Kalshi's legal team knows the difference between a company fighting a regulator and a company performing one for an audience that includes other courts.

Six days after that injunction landed, the state of Washington told Crypto.com it would not enforce the same Washington law against Crypto.com's event contracts until appeals in a higher court were resolved. Kalshi's lawyers filed a motion on Thursday making that sequencing the centre of their argument. The state had called Kalshi's contracts intolerable. Then it handed the identical contracts to a competitor with a note saying enforcement could wait.

This is the strongest version of the selective-enforcement argument that has been circulating in prediction market litigation for months. It is not a preemption claim. It does not require a federal ruling on CFTC jurisdiction. It asks a state court to answer a simpler question: if the conduct is illegal, why does legality depend on the company's name?

State Attorney General Nick Brown's office has not yet responded publicly to the motion. The framing they used when the injunction was granted — that Kalshi "has gotten rich promoting wagers on sports, elections, natural disasters, events related to the Iran War, and more" — is political language, not legal analysis. Political language tends to hold up well in press releases and less well when a court asks why the identical product is fine when Crypto.com sells it.

The consensus view among prediction market observers is that Kalshi's federal preemption strategy is its main line and that state-level arguments are rearguard actions. That reading underestimates this motion. Preemption requires winning at the circuit level, which takes time and carries genuine appellate risk. Selective enforcement, if the facts hold, can be resolved in the same court that issued the injunction. Kalshi does not need the 6th Circuit to move first. It needs Nick Brown's office to explain the six-day gap.

Whether the court finds the Crypto.com arrangement materially identical to Kalshi's is the operative question. The state will likely argue that the Crypto.com non-enforcement decision was a procedural accommodation pending appeal rather than a substantive endorsement of the contracts — that the law still applies, just not yet. That is a defensible position, but it requires the court to accept that a temporary carve-out for one competitor does not constitute the state taking a position on the underlying conduct. Courts have found that distinction persuasive before. They have also found it unpersuasive.

Customers in Washington, Michigan, and Nevada are currently locked out of Kalshi while that question works through the system. Michigan and Nevada are separate disputes with separate postures. What Washington now has that the others lack is a documented moment where the enforcing authority drew a line around one company and left another standing outside it.
