Court Opts Not to Lift Kalshi Washington Ban

Kalshi’s latest bid to jumpstart their prediction market platform back in the state of Washington has been denied. The state previously restricted the site from offering its event contract product to WA citizens, and an attempt to uplift the ban failed this past week.

Washington just got done securing a win over Kalshi, which ended the prediction market site’s ability to serve users in the state. The court order ruled that Kalshi’s event contracts violated state gambling laws and were therefore illegal.

Kalshi Fails in Bid to Lift Washington Ban

The battle between Kalshi and Washington began last March, when the state sued the surging prediction market. More action arrived later in July, with the final order coming in August that forced Kalshi to cease all operations in the state.

The ruling declared that Kalshi’s prediction market offerings resembled online gambling, which is illegal under Washington's state gambling laws. The order specifically demanded Kalshi to stop offering contracts to state citizens, and also initiated geofencing requirements.

Weeks later, Kalshi attempted to get the court to reconsider the decision, with one key argument being that Washington was more lenient with a competing prediction market platform. Judge John McHale saw over the case and ultimately ruled against lifting the restrictions.

Why This Latest Kalshi Court Loss Matters

Kalshi already lost this fight in August, so losing it again in September isn’t overly shocking. It does display the company’s persistence in the ongoing legal battle against U.S. states, though.

More importantly, Washington ruling against Kalshi twice in a row is a sobering reminder that U.S. states still have say in who operates within their borders. This is interesting for the overall prediction market vs. online gambling debate, but it’s especially compelling in states that already don’t allow online betting of any kind.

This means states are arguing that prediction market event contracts operate as sports betting wagers, and Washington is an example of a state being effective with that stance.

The bigger picture, of course, isn’t just defining prediction markets wagers; it’s the fact that U.S. states arguably have too much power when fighting an entity that is already federally approved.

Prediction Markets Facing Serious Tests vs. U.S. States

Kalshi continues to have run-in after run-in with U.S. states as it attempts to find firm footing in America, while also aggressively seeking wider expansion globally.

Washington’s rejection is just another reminder that U.S. states monitor their own jurisdictions, and that at least for now, being federally regulated doesn’t mean prediction markets are free to operate as they choose.

This isn’t the first case where Kalshi had to bow out of a U.S. state, and it won’t be the last. But it does reinforce the more powerful debate; should federal regulation trump state and tribal gaming rules?

As long as that line is allowed to be blurred, states will attempt to maintain control. After all, it’s in their best interest, whether due to profit from state regulation or Tribal monopoly, to dictate what prediction markets can or cannot do.

The Trade Handle Prediction Markets Take

Kalshi has numerous ongoing legal battles, and the scope is widening. They’re also not alone, as prediction markets in general are under fire. Several U.S. states want them to exit their jurisdiction or cave to their demands, but the funny thing is the incentive always seems to be different.

Some states currently want no gambling of any kind and file Kalshi and other prediction markets in that category. Some states allow gambling and also want Kalshi to accept that definition. And others have Tribal gaming control wanting to maintain dominance in the gambling realm.

Of course, where one door closes, another may open. With Kalshi recently striking a deal with a Tribe, they could be setting up a positive movement toward knocking out one frustrating roadblock.
