New Jersey officials have asked the U.S. Supreme Court to review a case involving Kalshi’s offer of contracts on sports outcomes to state residents. The petition was filed by the state’s Attorney General and its gaming regulators.

What happened

New Jersey’s Attorney General, along with the state’s gaming authorities, submitted a petition for a writ of certiorari to the U.S. Supreme Court. The move comes in response to Kalshi offering sports event contracts to New Jersey residents. The goal is to get the nation’s highest court to weigh in on the case through formal proceedings.

What’s the dispute about?

The core issue: whether Kalshi can legally offer contracts on sports outcomes to people in New Jersey. State officials want the Supreme Court to clarify the legal line between prediction markets and products tied to sports results—a hot topic in the ongoing debate over where prediction markets end and sports betting begins.

Why it matters for the market

This Supreme Court request puts a spotlight on how prediction markets and sports event contracts are regulated in one of the biggest states in the U.S. The outcome could impact everyone in the space, from companies offering probabilistic contracts to market participants and platforms looking to serve state residents.
