Kalshi CEO Tarek Mansour says state policing would drive US prediction markets offshore, though two of three appeals courts have sided with states. Sports slid from 95% of Kalshi's revenue to about two-thirds, a share change that cannot show how much volume left.

Thirty-nine states, D.C., 145 tribal nations, the NFL and Gary Gensler urged the Supreme Court to decide whether sports prediction contracts are swaps. Two of the three appeals courts to rule have called those contracts state-regulated gambling, so platforms on federal licenses still face two possible regulators.

Mike Selig's CFTC put one rule into force Friday and proposed another defining event contracts as swaps under its sole oversight, with 30 days for comment. States have won two of three federal appellate rulings so far, and the Supreme Court has been asked to settle the fight.

New Jersey's bid for Supreme Court review of a ruling that shields Kalshi's sports contracts from state gaming law won the NFL's backing in an October 8 brief. The league counts its games as $1.8 billion of $3.3 billion traded on prediction markets on the season's first Sunday, so a ruling would decide who regulates most of that money.

Justice Samuel Alito's recusal means a 4-4 Supreme Court split would keep Boulder's climate suit against Exxon Mobil and Suncor alive in state court. Dozens of similar city and county suits turn on the same ruling, and the companies warn the damages could run to billions of dollars.

Kalshi paid Blanche Lincoln's firm $180,000 in 2024 to lobby on the event contracts she warned in 2010 could become a backdoor for sports gambling. Her firm now asks the CFTC to take sole charge of the sports contracts behind most of Kalshi's volume, while state regulators can quote her 2010 speech back at her.

Sixth Circuit judges let Ohio and Tennessee enforce gambling law against Kalshi's sports contracts, putting two of three appeals courts on the states' side. New Jersey's contrary ruling still stands, so the same federally registered contract now has a different legal status depending on the state.

Judge Martha Pacold barred Illinois from enforcing its license and criminal rules against Kalshi but deferred a fee stack that takes 15% of gross receipts. The fees stay on the state's books while she hears more argument on whether a charge that size amounts to regulation.

Illinois agreed to delay its 0.2% crypto transaction tax six months, to July 1, 2027, in a joint motion a judge must still approve. The law stays on the books while two lawsuits proceed, so brokers who must collect it get more time to build for a levy that can still arrive in July.
