State gaming lawmakers join push for Supreme Court to hear Kalshi case
The National Council of Legislators from Gaming States (NCLGS) filed an amicus brief urging the U.S. Supreme Court to hear a case involving prediction market platform Kalshi. The lawmakers, representing states with established gaming industries, warned that a ruling preventing states from regulating prediction markets could affect existing gambling frameworks. The filing centers on the regulatory status of Kalshi's event contracts.
NCLGS adds state legislative muscle to a cert petition pool that already includes New Jersey and bipartisan federal lawmakers. Kalshi, each new voice at the Court makes a grant harder to deny and a denial harder to explain. The justices rarely take cases, but a split between the Third Circuit's Kalshi backing and the Ninth Circuit's twin rejections on tribal lands gives them a textbook reason to intervene.
A grant would freeze the state-by-state enforcement patchwork in Nevada, Connecticut, and California tribal lands. A denial leaves Kalshi fighting parallel state suits with circuit precedent running against it. Legal spend compounds faster than any single case resolves. Traders hold positions whose validity shifts with geography, not regulation. The NCLGS brief signals that states themselves want clarity, not more border-by-border litigation.
Adds to the petition-side briefs pressing the Supreme Court on Kalshi preemption this quarter, joining New Jersey's state filing.
