Overview
Updated YesterdayUtah can keep enforcing its ban on sports-style prediction bets while Kalshi appeals. The 10th Circuit on September 10 declined to pause the state's prop betting law, rejecting the company's request to keep trading during the appeal.
The case turns on one question: are prediction markets gambling, which states may ban, or federally regulated commodities trading, which they may not? Kalshi, registered with the Commodity Futures Trading Commission, says federal law preempts Utah's ban. A district judge sided with Utah on September 8, and the appeals court has now kept the ban in place while it reviews that ruling.
Why it matters
If Utah's ban survives, states can block federally regulated prediction markets—deciding where sports-style betting on platforms like Kalshi stays legal.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
Murphy v. NCAA (2018)
The Supreme Court struck down the Professional and Amateur Sports Protection Act, the 1992 federal law that barred most states from legalizing sports betting. The ruling returned the decision to the states.
New Jersey and then dozens of states legalized sports betting within a few years.
Affirmed that states, not the federal government, set gambling policy within their borders—the principle Utah now leans on.
Utah's argument echoes Murphy: states hold authority to ban or allow gambling, and federal commodities law doesn't strip that power.
Kalshi v. CFTC (2024)
D.C. District Judge Jia Cobb ruled the CFTC overstepped by blocking Kalshi's election contracts, saying the agency couldn't ban contracts just because betting on them might undermine public confidence. Kalshi began offering congressional control markets within days.
Prediction markets expanded into U.S. elections, with heavy trading on the 2024 presidential race.
Established that CFTC-registered exchanges can offer event contracts absent explicit commission rules, fueling the state pushback Utah's law represents.
The preemption argument Kalshi won in Washington failed in Utah, showing how the fight over prediction-market jurisdiction is playing out differently across courts.
Bucket shop crackdown (early 1900s)
Bucket shops let people bet on stock and grain prices without taking real positions, and states treated them as illegal gambling. The Grain Futures Act of 1922 and the Commodity Exchange Act of 1936 drew a line between these gambling operations and legitimate futures exchanges.
Federal regulation of futures created an orderly market while states kept anti-gambling laws on the books.
The Commodity Exchange Act's structure of overlapping state and federal authority persists—and is now at the center of the Kalshi case.
The current fight reprises an old question: where does speculation end and gambling begin, and which level of government gets to decide.
