Utah Attorney General Derek Brown filed a civil lawsuit against Kalshi alleging its event contracts are illegal gambling under the Utah Constitution. Full Spectrum Sports Intelligence is a research desk only — no wagers, no prediction market.
What the state is seeking
- An injunction to stop Kalshi from offering sports, election, politics, culture, and mentions contracts to Utah residents.
- Court-approved geolocation controls to enforce a block.
- Restitution and disgorgement of profits. The complaint estimates Kalshi collected between $30.6 million and $61.2 million in fees from more than 32,000 verified Utah accounts as of mid-October 2026.
- The complaint also names two Susquehanna-affiliated trading firms that provide pricing and liquidity.
Federal context
Kalshi maintains it is a federally regulated exchange overseen by the Commodity Futures Trading Commission (CFTC) and that state gambling laws cannot veto federal jurisdiction. In February 2026, Kalshi sued Utah officials arguing the Commodity Exchange Act preempts state law. In August 2026, U.S. District Judge Robert Shelby granted summary judgment to Utah, holding that federal commodities law does not override Utah's gambling ban. Kalshi appealed to the 10th Circuit, which on September 8 denied a stay of enforcement pending appeal. That appeal remains pending.
The October state lawsuit follows that federal ruling and alleges continued activity in Utah after the decision.
