The legal position in Illinois
Since April 2025 the Illinois Gaming Board has sent cease-and-desist letters to over a dozen operators, including Kalshi, Polymarket, Robinhood and Crypto.com. In 2026 the governor also signed an executive order barring state employees from trading on inside information, and the CFTC sued Illinois in federal court — making it one of the nine states the agency has taken to court to defend its exclusive jurisdiction.
Illinois runs a large, high-tax legal sports-betting market, giving it a clear incentive to treat sports event contracts as competing wagers. Whether it can is the preemption question now before the courts — see our legality overview.
Which platforms operate in Illinois
With state cease-and-desist letters and CFTC litigation both live, availability from Illinois is platform-specific and can change with each ruling. Some operators may limit access while the case proceeds. Rely on each platform’s own eligibility check at sign-up rather than any general claim about the state.
This state is in active litigation and the position can change on a single ruling. This page is general information as of June 2026, not legal advice. Always confirm the current position on the platform’s own eligibility check before depositing.

Frequently asked questions
Can I use prediction markets in Illinois?
It is contested. The Illinois Gaming Board has issued cease-and-desist letters to more than a dozen operators, but the CFTC has sued the state arguing federal law preempts that enforcement. Whether a platform is reachable from Illinois depends on how it is responding — check its live eligibility page before funding.
Why is Illinois fighting prediction markets?
Illinois has a large, high-tax legal sports-betting market and views sports event contracts as competing, unlicensed wagers. The state issued cease-and-desist letters on that basis; the CFTC counters that event contracts are federally regulated derivatives outside state gambling authority.
