New Jersey asks the Supreme Court to settle the prediction-market split

New Jersey has taken the prediction-market fight to the top of the legal pyramid, petitioning the US Supreme Court to resolve whether Kalshi's sports event contracts are federally regulated derivatives or unlicensed sports wagers.

Why SCOTUS might take it

The petition lands on the strongest possible procedural footing: an acknowledged circuit split. The Sixth Circuit ruled in September that sports event contracts can be regulated as gambling under state law; the Third Circuit ruled for Kalshi on its New Jersey case; and the Ninth Circuit's en banc rehearing is pending. A split this clean is exactly what the Court's cert criteria are built around — and the underlying market, now measured in billions of monthly notional volume, raises the stakes past the academic.

• Sixth Circuit: sports contracts are gambling — states can regulate.
• Third Circuit: Kalshi's contracts are derivatives — CFTC has exclusive domain.
• Ninth Circuit: rehearing pending, CFTC rulemaking looming.
• SCOTUS: petition filed, response due, four votes needed to grant.

What a ruling would settle

A merits decision either way would redraw the industry map in a single opinion: if event contracts are 'gaming' under the CEA's exclusion, the state-licensing patchwork becomes permanent; if they're preempted derivatives, every state cease-and-desist letter of the past year becomes a paperweight. The CFTC's pending rulemaking could still moot the whole fight — which is itself an argument the Court will weigh when deciding whether to wait or weigh in.

Background: the Sixth Circuit ruling that created the split, Nevada's enforcement line, and the federal framework beneath it all.
