A Washington judge’s preliminary injunction against Kalshi marks the latest sign that prediction markets are moving from regulatory gray zone to direct courtroom confrontation. Puget Sound Business Journal reports that a King County Superior Court judge found Kalshi likely violated Washington gambling laws, adding another state-level challenge to a platform already at the center of a broader federal-versus-state fight over event contracts.
Washington court deals Kalshi a setback
The Washington ruling matters because it frames Kalshi not just as a federally regulated event-contract venue, but as a business that may still run afoul of state gambling statutes. A preliminary injunction is not a final ruling, but the judge’s finding that violations are likely raises immediate operational and legal pressure.
For market watchers, the key question is whether more states pursue similar actions, especially around sports-linked contracts. If state courts continue treating certain event markets as gambling, platforms may face a patchwork of restrictions even as they argue for federal oversight.
CFTC pushes back in Michigan
Bloomberg Law reports that the CFTC invoked emergency authority to counter a Michigan state-court order requiring Kalshi to dissolve and refund sports-related event-contract trades placed by Michigan residents.
That move is significant: the federal regulator is not merely observing the state-level fight, but actively challenging a state court’s attempt to unwind trades. The clash highlights a central unresolved issue for the industry — whether federally regulated prediction markets can be forced by individual states to reverse or restrict activity that states view as illegal gambling.
France blocks Polymarket
Polymarket is facing its own regulatory wall in Europe. France’s Autorité Nationale des Jeux said it ordered French internet service providers to block Polymarket, calling the site an unauthorized promotion of illegal gambling services.
The French action underscores that prediction markets’ regulatory problems are not limited to the United States. Even as trading activity remains robust across crypto-native platforms, access can change quickly when national gambling regulators decide a platform is operating outside local rules.
CFTC probes alleged speech-related Kalshi profits
Bloomberg Tax reports that the CFTC is investigating a White House teleprompter operator who allegedly profited from Kalshi wagers on President Donald Trump’s speeches. Kalshi said it froze more than $90,000 in profits.
The probe cuts to a sensitive issue for political and current-events markets: information asymmetry. If insiders or adjacent personnel can profit from nonpublic knowledge, regulators may scrutinize market integrity, surveillance controls, and platform enforcement more aggressively.
Why it matters
This week’s news points in one direction: prediction markets are becoming too large and too visible for regulators to ignore. Courts, gambling agencies, and the CFTC are all asserting authority at once. For followers of the space, the biggest story is no longer just market volume or product growth — it is whether platforms can establish a durable legal framework before state and international enforcement fragments access.
