- Federal judge determines that Kalshi contracts likely qualify under federal derivative regulations
- Arizona is prohibited from pursuing criminal charges against the Kalshi prediction market
- Judgment escalates national legal disputes concerning sports prediction markets
A federal judge has halted Arizona from enforcing its gambling legislation against the prediction-market entity Kalshi as the legal discourse regarding event-based trading unfolds across the country.
In a detailed 17-page ruling released on Monday, U.S. District Judge Michael T. Liburdi granted a preliminary injunction that blocks Arizona’s regulatory bodies and prosecutors from initiating criminal or civil proceedings against Kalshi concerning its sports and event contracts.
In March, Arizona initiated the inaugural criminal lawsuit against a CFTC-registered prediction-market operator, filing a 20-count criminal accusation against Kalshi.
This complaint claims the firm is taking wagers on political outcomes, college athletic events, and player performances, breaching state gambling statutes.
States vs. Kalshi
Judge Liburdi’s verdict transforms a temporary restraining order issued in April into a more sustained preliminary injunction, preventing Arizona from proceeding with enforcement actions against Kalshi.
This ruling represents one of the most favorable outcomes for Kalshi in its ongoing confrontations with state gaming authorities, which assert that the platform operates as an unlicensed bookmaking entity masquerading as a federally regulated financial exchange.
Regulated by the Commodity Futures Trading Commission (CFTC), Kalshi permits users to trade contracts linked to prospective events, such as elections, economic indicators, and sports results.
Liburdi reasoned that these contracts likely fall under the category of “swaps” as defined by the Commodity Exchange Act, thus placing them within the singular jurisdiction of the CFTC.
The Court finds that federal legislation supersedes state gambling regulations where they aim to manage derivatives traded in markets overseen by the CFTC,” Liburdi asserted.
The judge dismissed Arizona’s claim that sports results are categorically different from the “events” recognized by federal commodities legislation. Rather, the opinion concluded that contracts contingent on a team’s victory or a candidate’s election resonate well within Congress’ broad definition of swaps associated with future scenarios that bear economic consequences.
The decision leaned heavily on the federal preemption doctrine, affirming that Congress envisioned derivatives markets operating under a cohesive national standard rather than an inconsistent array of state-specific governance.
Fragmented Regulations
Liburdi cautioned that should states be allowed to bring legal actions against DCM operators like Kalshi, they would face the “real possibility of fifty disparate regulatory frameworks, each having the power to limit the types of contracts available on each exchange.”
He acknowledged that Kalshi’s contracts might resemble “gaming” in a general sense but emphasized that the determination of whether such contracts contravene federal event-contract regulations should rest with the CFTC and not state gaming authorities.
This ruling surfaces during a nationwide legal contention about prediction markets. Various state courts have issued divergent outcomes, while federal appellate courts are increasingly engaging in the discourse.
The ruling notes that the Third Circuit has recently sided with Kalshi in a similar case, while the Ninth Circuit is anticipated to release its decision shortly.
Currently, the injunction prevents Arizona from filing criminal charges, civil claims, subpoenas, or investigations related to event contracts available on CFTC-regulated platforms. The state has yet to announce whether it plans to appeal.
