Prediction Market Regulation in the US: 2026 Guide
Three platforms, three different regulatory paths, and a live court fight that could reshape all of them. Prediction market regulation in the US in 2026 isn't a single rulebook — it's the CFTC threading three separate legal structures together while states push back on jurisdiction. Here's exactly where each major platform stands, verified against CFTC filings and court records as of July 2026.
The CFTC's role, in plain terms
The Commodity Futures Trading Commission (CFTC) treats event contracts — YES/NO instruments that pay out based on a real-world outcome — as derivatives, the same broad category as futures and swaps. A platform offering them to US retail traders generally needs to operate as, or route through, a CFTC-licensed Designated Contract Market (DCM), the same license category that governs commodity and financial futures exchanges. That single requirement is why Kalshi, Polymarket, and PredictIt look so different structurally even though they offer similar products.
Kalshi: the original CFTC-licensed DCM
Kalshi received its CFTC Order of Designation on November 4, 2020, making it the first federally regulated prediction market in the US. It operates through two entities: KalshiEX LLC holds the DCM license and lists markets; Kalshi Klear LLC is the Derivatives Clearing Organization (DCO) that holds customer funds at a federally regulated clearinghouse. Event contracts trade $0.01 to $0.99, with one YES and one NO contract on each market always summing to exactly $1.
Kalshi is legal in all 50 states as a federally licensed DCM, but that hasn't stopped state gaming regulators from challenging specific product categories — sports event contracts in particular, which some states argue function like sports betting and therefore fall under state gambling law rather than federal commodities law.
The Third Circuit ruling: a preemption win for Kalshi
In May 2026, the Third Circuit Court of Appeals ruled on exactly that dispute. New Jersey had argued its state gambling law should apply to Kalshi's sports contracts. The court sided with Kalshi, holding that the Commodity Exchange Act gives the CFTC exclusive jurisdiction over sports event contracts listed on CFTC-licensed DCMs — federal law preempts the state statute. It's a significant precedent, but it applies to the Third Circuit's jurisdiction specifically, and outcomes in other circuits and states still vary. Traders should not assume the ruling settles every state dispute automatically.
Polymarket: from offshore exchange to regulated US entity
Polymarket took a different route. It launched in 2020 as a peer-to-peer, crypto-settled exchange on Polygon with no US license, geoblocking American users from the start. In July 2025, it acquired QCEX — an existing CFTC-licensed DCM and clearinghouse — for roughly $112 million, buying its way into the regulatory perimeter rather than building from scratch. The same month, a CFTC enforcement probe that had been open against Polymarket since 2022 was dropped.
In November 2025, Polymarket received an Amended Order of Designation from the CFTC, authorizing an intermediated, federally regulated US exchange run through the QCEX entity. That regulated product went live to US users on December 2, 2025, and Polymarket dropped its iOS waitlist in May 2026, putting the app fully live on iPhone for US users.
Two important caveats. First, Polymarket's original international exchange — the one most traders associate with the brand — stays geoblocked to US users; only the separate QCEX-based US exchange is available domestically. Polymarket filed with the CFTC on April 28, 2026 seeking to change that and let US users trade the main offshore exchange directly, but as of this writing that request is pending, not approved. Second, a new CFTC probe into Polymarket opened in June 2026, even though the 2022 case is closed — regulatory scrutiny on this platform hasn't ended, it's shifted focus.

PredictIt: the narrow no-action survivor
PredictIt operates under a CFTC no-action framework, the same regulatory posture as the academic Iowa Electronic Markets rather than a DCM license. Years of litigation over its status resolved in July 2025, producing an amended no-action letter under new academic and nonprofit management. The per-contract position cap — previously $850 — is now tied to the federal campaign-contribution limit, raising it to up to $3,500 per position, and the old 5,000-trader-per-contract cap was removed. PredictIt is restricted to political-event contracts and academic research use, which keeps its liquidity far below Kalshi or Polymarket. Fees run 10% on gross profits plus a 5% withdrawal fee.
State-by-state friction
Federal DCM status doesn't automatically settle every state's position. The CFTC is actively suing several states over their attempts to restrict or ban prediction market trading:
- Minnesota — a state ban on prediction market trading takes effect August 1, 2026.
- Connecticut, Arizona, Illinois — ongoing disputes between state regulators and the CFTC over jurisdiction, unresolved as of July 2026.
State status is a moving target. Before funding an account on any platform, check your specific state's current position — a market being federally legal doesn't guarantee your state agrees, and enforcement postures are still being litigated.
Regulatory snapshot by platform
| Platform | Regulatory status | Key 2026 event |
|---|---|---|
| Kalshi | CFTC-licensed DCM since Nov 2020 | Third Circuit preemption win, May 2026 |
| Polymarket (US) | CFTC Amended Order of Designation via QCEX, Nov 2025 | New CFTC probe opened June 2026; offshore-access filing pending since Apr 2026 |
| PredictIt | CFTC no-action framework | Amended letter + higher position caps, July 2025 |
The throughline across all three: the CFTC is the deciding federal authority, but "regulated" doesn't mean "settled." Kalshi is fighting state-by-state sports-contract challenges even after a circuit court win. Polymarket is running two exchanges under two different legal postures simultaneously while a new federal probe is open. PredictIt survived a near-death litigation cycle by narrowing its own scope.

Always verify current fee schedules and licensing status directly — cftc.gov publishes enforcement actions and DCM designations, and both Kalshi and Polymarket document their current legal structure on their own sites.

FAQ
Who regulates prediction markets in the US?
The CFTC (Commodity Futures Trading Commission) is the primary federal regulator. Kalshi operates as a CFTC-licensed Designated Contract Market since November 2020. Polymarket's US exchange operates under an Amended Order of Designation obtained in November 2025 after acquiring the licensed exchange QCEX. PredictIt runs under a separate CFTC no-action framework.
Is Polymarket fully legal for US users?
Polymarket's regulated US exchange, built on the QCEX license, has been live since December 2, 2025 and is CFTC-supervised. Its original offshore exchange remains geoblocked to US users. State-level status varies — Minnesota's ban takes effect August 1, 2026, and Connecticut, Arizona, and Illinois have ongoing disputes with the CFTC over jurisdiction.
What did the Third Circuit rule on Kalshi sports contracts?
In May 2026, the Third Circuit Court of Appeals ruled that the Commodity Exchange Act gives the CFTC exclusive jurisdiction over sports event contracts listed on CFTC-licensed Designated Contract Markets, preempting New Jersey's state gambling law. It's a strong precedent for Kalshi but doesn't resolve every state's position.
Why is Minnesota banning prediction markets?
Minnesota passed a state-level restriction on prediction market trading that takes effect August 1, 2026, part of a broader pattern of state gaming regulators arguing that event contracts function like sports betting or gambling, which they claim falls under state rather than federal jurisdiction.
