Overview
A closely-watched tribal challenge. Judge William Conley (W.D. Wis.) found the Ho-Chunk Nation likely to succeed on its Indian Gaming Regulatory Act claim that Kalshi’s sports contracts intrude on tribal gaming rights, but denied a preliminary injunction for lack of shown irreparable harm (May 2026); he dismissed the tribe’s Lanham Act and RICO claims but let the IGRA claim proceed.
On September 11, 2026 he denied the Nation leave to amend its Lanham Act claim, certified the May ruling for interlocutory appeal — calling the questions novel, without controlling precedent in the Seventh Circuit, and likely headed to the Supreme Court — and stayed the whole case. Kalshi petitioned the Seventh Circuit for permission to appeal on September 21 (No. 26-8020). The May 2027 trial date is effectively off the calendar while the stay runs. The Nation has filed the Ninth Circuit’s Blue Lake Rancheria decision as supplemental authority.
