Crypto.com's North American Derivatives Exchange became the third party asking the Supreme Court to review the Ninth Circuit's Nevada ruling on sports event contracts, joining New Jersey and Robinhood, while Kalshi pursues en banc rehearing at the circuit level instead. Kalshi leaned further into celebrity marketing this week, debuting ads with Pete Sampras and Marshawn Lynch as the industry heads into a fall stretch that overlaps NFL season with the midterm election cycle for the first time. Trading volume and regulatory activity are both expected to concentrate into that window rather than spread across the year.

NADE files third Supreme Court petition over Ninth Circuit's Nevada ruling
North American Derivatives Exchange, Crypto.com's CFTC-registered exchange unit, filed a petition for a writ of certiorari with the U.S. Supreme Court on September 11, 2026 asking the justices to review the Ninth Circuit's August 28 ruling that Nevada may regulate sports event contracts as gambling. It is the third petition asking the Court to resolve the same preemption question, after New Jersey's September 2 petition and Robinhood's September 9 petition, while Kalshi separately sought en banc rehearing at the Ninth Circuit rather than go directly to the Supreme Court. The stacked petitions raise the odds the Court takes up the circuit split between the Third Circuit's Kalshi-favorable ruling and the Ninth Circuit's Nevada-favorable one.

Kalshi debuts Pete Sampras and Marshawn Lynch ad campaigns
Kalshi rolled out two celebrity-fronted campaigns this week: a US Open-timed spot narrated by Pete Sampras tied to its multiyear USTA sponsorship, and a big-budget commercial starring Marshawn Lynch directed by Craig Gillespie and shot on 35mm. The campaigns extend a pattern of celebrity-driven user-acquisition spend across the sector and raise the marketing bar competitors are being asked to match heading into the NFL and midterm election season.

NFL season and midterm elections overlap for a first-of-its-kind fall for prediction markets
CNBC reported September 13 that prediction-market operators are entering the fall with the NFL season and the midterm election cycle running concurrently for the first time, a combination Robinhood futures and prediction-markets general manager JB Mackenzie called a "supercycle" for the industry. Kalshi and Polymarket remain the two largest platforms by volume, with a widening field of smaller CFTC-registered exchanges competing for the same sports and political contract flow. For operators and their compliance teams, the overlap concentrates volume, and regulatory scrutiny, into a single compressed period rather than spreading it across the year.
