Overview

The second state to bring criminal charges against Kalshi, after Arizona in March 2026. On October 28, 2026 the Utah Attorney General’s Office filed a co-defendant information in Salt Lake County charging KalshiEX, LLC with 14 counts: one second-degree felony count of a pattern of unlawful activity, twelve third-degree felony counts of online gambling promotion and one misdemeanor count of general gambling promotion. It names co-founders Tarek Mansour (CEO) and Luana Lopes Lara (COO) as co-defendants. The charges rest on twelve sports trades an undercover agent of the Attorney General’s Office placed on Kalshi from Salt Lake and Davis Counties between September 13 and 24, 2026, each of which the information treats as a separate gambling episode.

The information leans on Utah’s civil win: it recites that the federal court granted Utah summary judgment in August and that the Tenth Circuit refused Kalshi an injunction pending appeal, and alleges Kalshi kept offering contracts in Utah anyway. The filing came two days after the United States and the CFTC sued Utah to stop its enforcement, and eight days after the Attorney General’s civil suit. The court summoned Kalshi to appear in person rather than issuing warrants. These are charges, not findings. (Caption, counts and filing date read from the signed information; case number, judge and appearance date from the court’s October 30 notice and amended summons.)
