Federal Judge Blocks Illinois Prediction Market Rules in Kalshi Win
United States.- 7 October 2026 | www.zonadeazar.com A federal judge has preliminarily blocked several Illinois rules targeting prediction markets after finding that sports event contracts offered by platforms such as Kalshi likely qualify as swaps under federal law.
The decision represents another major development in the dispute between prediction markets overseen by the Commodity Futures Trading Commission, CFTC, and states seeking to apply their own gambling laws.
Preliminary Injunction Granted
US District Judge Martha Pacold granted preliminary injunctions in litigation involving KalshiEX, Coinbase and the CFTC.
The ruling temporarily prevents Illinois from enforcing several restrictions while the underlying cases continue.
It is not a final judgment on the merits.
Contracts Likely to Qualify as Swaps
Pacold found that many of the financial instruments at issue are likely to fall within the Commodity Exchange Act’s definition of swaps.
At this stage of proceedings, the fact that the products relate to sport or may be used for entertainment does not prevent them from potentially falling under the federal derivatives framework.
Conflict With State Regulation
Illinois had sought to regulate prediction markets through its gambling regime.
The provisions covered matters including:
- Which contracts could be sold.
- Where products could be offered.
- Who could trade them.
- Restrictions on sports event contracts.
- A ban on participation by people under 21.
Separate Market for Illinois
The judge said Illinois’ rules would effectively force Kalshi to create a market specifically for state residents.
That would require separate geographic, trading and age restrictions from those used within its federally regulated infrastructure.
Non-compliance could also expose the company to criminal penalties under state law.
Commodity Exchange Act Dispute
The central legal issue is whether the federal Commodity Exchange Act pre-empts state gambling legislation.
The plaintiffs argue that contracts traded through federally regulated markets fall within the exclusive jurisdiction of the CFTC.
Illinois argues that it retains authority where those products function in practice as wagers on sporting events.
Kalshi Lawsuit
Kalshi sued Illinois in June after state lawmakers introduced prediction-market provisions as part of the state’s fiscal budget.
The company sought to prevent those measures from restricting its event-contract offering in Illinois.
CFTC Files Its Own Case
The CFTC launched separate litigation in April.
The federal regulator argued that Illinois and other states had taken overly aggressive steps to restrict prediction markets operating within federally regulated markets.
Irreparable Harm
Pacold found that the plaintiffs had shown a sufficient likelihood of success on the merits and demonstrated that they could suffer irreparable harm if the restrictions were enforced while litigation continued.
Those findings supported the preliminary injunction.
1.75% Tax Remains Unresolved
The ruling did not fully resolve Illinois’ proposed tax regime.
The state planned to impose a 1.75% per-wager or transaction tax on sports event contract trading, alongside licensing requirements potentially costing millions of dollars.
Pacold left open the possibility that taxing revenue or transaction fees may raise a different legal issue from directly regulating the structure of the market.
Illinois Gaming Board Action
In April, Illinois Gaming Board Administrator Marcus Fruchter sent cease-and-desist letters to:
- Kalshi.
- Polymarket.
- Crypto.com.
- Robinhood.
The regulator alleged that the companies were offering illegal gambling under Illinois law.
Diverging Federal Decisions
The Illinois ruling again highlights the lack of a uniform federal approach.
Courts in other jurisdictions have reached different conclusions over whether sports event contracts are governed exclusively by federal commodities law or may also be regulated under state gambling frameworks.
Next Steps or Impact
The parties must submit a proposed injunction consistent with Pacold’s opinion by 29 October.
Until then, key Illinois restrictions will remain preliminarily blocked.
The underlying litigation will continue, while both the broader regulatory dispute and the treatment of the state’s tax remain unresolved.
With federal courts continuing to reach differing conclusions, the future of sports prediction markets may ultimately require clarification from higher federal courts.
