Prediction market law in Oregon
No public action found
Oregon has not sued or issued orders against prediction markets, though its attorney general joined multistate briefs backing other states.
No Oregon lawsuit, cease-and-desist, or prediction-market legislation was found. Attorney General Dan Rayfield signed Oregon onto a multistate effort opposing Kalshi before the Ninth Circuit, and Oregon joined the June 2026 Sixth Circuit amicus brief supporting Ohio. A private class action filed in Oregon in February 2026 alleged that Kalshi violates state gambling law and was reportedly transferred to the Southern District of New York.
