  1. Court ruling

    Sixth Circuit: Ohio and Tennessee may apply their gambling laws to Kalshi sports contracts

    On September 25, 2026, the Sixth Circuit ruled in KalshiEX v. Schuler and KalshiEX v. Orgel (Nos. 26-3196/5235) that Kalshi has not shown its sports-event contracts are "swaps" within the CFTC’s exclusive jurisdiction, and that even if they were, the Commodity Exchange Act does not preempt Ohio’s or Tennessee’s gambling laws. The court affirmed the Southern District of Ohio’s denial of a preliminary injunction and vacated the Middle District of Tennessee’s injunction that had protected Kalshi. The rulings concern preliminary injunctions; both cases return to the district courts.

  2. Court ruling

    Underdog sues officials in six states over sports event contracts

    Underdog’s exchange entity, Underdog Exchange DCM, Inc., filed federal suits on September 8, 2026 against officials in New Mexico, Ohio, Massachusetts, Wisconsin and Washington, and on September 15 against Connecticut officials (D. Conn. No. 3:26-cv-01499), days after Connecticut’s cease-and-desist order to Underdog Predict.

  3. State action

    Connecticut orders nine prediction-market platforms to stop offering sports contracts

    On September 10, 2026, Governor Ned Lamont announced that the Connecticut Department of Consumer Protection had issued nine cease-and-desist orders — including to Polymarket, Robinhood and Underdog Predict — ordering the platforms to stop offering "sports event contracts" or any other unlicensed online gambling to Connecticut residents, along with nearly 30 subpoenas related to prediction-market activity.

  4. Court ruling

    Ninth Circuit lets Nevada apply its gaming law to Kalshi sports contracts

    On August 28, 2026, the Ninth Circuit (KalshiEX v. Assad, No. 25-7516) affirmed a district court order dissolving Kalshi’s preliminary injunction against the Nevada Gaming Control Board, holding that Kalshi had not shown the Commodity Exchange Act preempts Nevada’s gaming law as applied to its sports event contracts. The court sent Nevada’s challenge to Kalshi’s election contracts back to the district court.

  5. Court ruling

    Connecticut sues Kalshi in federal court

    On August 26, 2026, the State of Connecticut filed State of Connecticut v. KalshiEX LLC in the U.S. District Court for the District of Connecticut (No. 3:26-cv-01382).

  6. Regulation

    CFTC orders Kalshi to honor Michigan trades, escalating the state–federal standoff

    On July 14, 2026, the CFTC stayed an emergency rule change KalshiEX had proposed in response to the Michigan court order directing cancellation of executed trades involving Michigan residents, and exercised its emergency authority to order the exchange to fulfill the open trades in accordance with its normal practices. Chairman Michael Selig said a state 'cannot force a DCM to violate its obligations' and warned that canceling executed trades 'risks a cascading effect on the entire marketplace.' The order effectively places Kalshi between a state court and its federal regulator. The CFTC's own tally of the jurisdiction fight now spans lawsuits against nine states — Arizona, Connecticut, Illinois, Kentucky, Minnesota, New Mexico, New York, Rhode Island, and Wisconsin — plus amicus briefs in the Sixth and Ninth Circuits and Massachusetts' highest court.

  7. Launch

    OpenAI surfaces Kalshi's World Cup odds inside ChatGPT

    The New York Times reported on July 13, 2026 that OpenAI has begun showing Kalshi's market-implied probabilities for 2026 World Cup matches inside ChatGPT search results — OpenAI's first tie-up with a prediction market. The integration is informational only: OpenAI's help pages stress that users cannot place bets through ChatGPT, and the deal is currently limited to World Cup queries. For market-data watchers it is another mainstream distribution channel for exchange-implied probabilities, following Kalshi's data deals with CNN and CNBC and Polymarket's with Dow Jones properties. Kalshi reported roughly $5.1 billion in trading volume in the tournament's opening week.

  8. Launch

    Rothera, Robinhood's new CFTC exchange, crosses $3B on World Cup flow

    Rothera — the CFTC-licensed exchange and clearinghouse operated as a joint venture between Robinhood and Susquehanna International Group — crossed $3 billion in cumulative trading volume by July 10, 2026, roughly two months after launch. Robinhood began routing a selection of World Cup and MLB event contracts to Rothera on June 4, redirecting flow it previously sent to Kalshi; the venue booked about $2 billion of notional volume in June, approximately 7% of US prediction-market share in its first full month. Structured as both a designated contract market and a clearing organization, Rothera gives Robinhood vertical control of the event-contract stack — and adds a third CFTC-regulated venue competing for macro and sports flow.

  9. State action

    North Carolina writes CFTC prediction markets into its tax code

    Gov. Josh Stein signed North Carolina's budget on July 7, 2026, adding a 6% tax on prediction-market platforms' net trading-fee revenue from state residents effective January 1, 2027, while raising the state's online sports-betting tax from 18% to 23%. The budget language goes beyond a levy: it acknowledges the CFTC's 'exclusive federal regulatory authority' over the venues — making North Carolina the first state to accommodate CFTC-regulated prediction markets in statute rather than sue them. The contrast with Kentucky, whose 14.25% rate the CFTC has characterized in court as effectively prohibitive, makes the 6% framework a template the industry is likely to point to in other statehouses.

  10. Court ruling

    New York federal court denies Kalshi injunction; company appeals to the Second Circuit

    On July 7, 2026, U.S. District Judge Analisa Torres (Southern District of New York) denied Kalshi's motion for a preliminary injunction against New York gaming regulators, holding that New York's gambling laws are not preempted by the Commodity Exchange Act as applied to its event contracts. Kalshi promptly appealed to the U.S. Court of Appeals for the Second Circuit. The ruling is a notable state-side win that deepens the split with the Third Circuit, which reached the opposite conclusion in New Jersey.

  11. Research

    World Cup pushes June prediction-market volumes to records

    CNBC reported on July 4, 2026 that the FIFA World Cup drove prediction-market volumes to all-time highs in June: Kalshi handled about $31 billion in notional volume (up from $18 billion in May), Polymarket's international platform about $10.8 billion with its US venue topping $3.5 billion, and newcomer Rothera roughly $2 billion. Sports contracts drove most of the surge — Kalshi's daily volume has held above $1 billion since the tournament's June 11 opener. For macro traders the salient point is liquidity: record volume and open interest deepen the order books that economic-indicator contracts share, even as the sports concentration sharpens regulatory scrutiny.

  12. Regulation

    Correction: PredictIt did not become a full CFTC DCM in January 2026

    A January 2026 story widely repeated across the trade press — and previously on this site — claimed PredictIt upgraded from its CFTC no-action letter to full DCM + DCO status. The CFTC registries show otherwise: the designation belongs to Aristotle Exchange, a separate exchange operated by PredictIt's parent company Aristotle (designated September 5, 2025, opened October 2025, acquired by Underdog in March 2026). PredictIt continues to operate under its 2014 no-action letter. Two associated claims need separating, and an earlier version of this entry got one of them wrong. The ~$700M daily volume surge does trace to the erroneous story and remains unverified. The limit raise does NOT: CFTC Letter 25-20 (July 14, 2025) amended the 2014 letter so the per-contract cap tracks the Federal Election Campaign Act individual-contribution limit — currently $3,500, adjusted for inflation every two years — up from the original $850. That raise is real and independent of the DCM story. Corrected 2026-07-31 against the CFTC letter itself.

  13. State action

    Michigan court halts Kalshi in-state after AG lawsuit

    On June 29, 2026, Ingham County Circuit Judge Rosemarie Aquilina granted a temporary restraining order sought by Michigan Attorney General Dana Nessel, blocking Kalshi from offering sports event contracts to Michigan residents. Nessel had sued the exchange in March, alleging its contracts function as unlicensed sports betting under state law. The order is one of a small number of state-court rulings — alongside the earlier Massachusetts injunction — that bar an operator outright rather than merely warning it.

  14. Court ruling

    CFTC sues Kentucky to defend federal jurisdiction over event contracts

    After Kentucky sued Kalshi and Polymarket alleging their sports event contracts are illegal sports betting, the CFTC filed suit against Kentucky on June 23, 2026 to assert its exclusive federal jurisdiction over event-contract markets. It is the latest front in a multi-state preemption fight — the CFTC's 2026 suits now span nine states — that legal observers expect to reach the Supreme Court.

  15. Regulation

    CFTC proposes rule defining permitted vs prohibited sports event contracts

    The CFTC published a 267-page Notice of Proposed Rulemaking on June 10, 2026. Outcome-based sports contracts — game and season winners, statistical performance — would generally be permitted, while injury, officiating, altercation, youth-sports, and first-pitch micro-prop contracts would be prohibited. A 45-day public comment period followed publication.

  16. State action

    Rhode Island AG sues Kalshi and Polymarket over sports event contracts

    Rhode Island Attorney General Peter Neronha sued Kalshi and Polymarket on May 21, 2026, alleging their sports event contracts constitute unlicensed sports betting under state gambling law. Rhode Island is also among the states the CFTC has separately sued to assert federal preemption — one of the dueling state-and-federal suits now defining the jurisdictional fight.

  17. Court ruling

    Third Circuit affirms Kalshi injunction against New Jersey — first federal appellate CEA-preemption ruling

    On April 6, 2026, the U.S. Court of Appeals for the Third Circuit affirmed, 2-1, a preliminary injunction in Kalshi's favor against New Jersey gaming officials (KalshiEX LLC v. Flaherty) — the first federal appellate decision holding that the Commodity Exchange Act's exclusive-jurisdiction framework preempts state gambling law as applied to sports-related event contracts on a CFTC-registered exchange. New Jersey is pursuing Supreme Court review. District and circuit courts elsewhere (Nevada, Maryland, and later New York) have leaned the other way, setting up a split the Supreme Court may ultimately resolve.

  18. Court ruling

    CFTC sues Arizona, Connecticut, and Illinois to assert federal jurisdiction

    After the three states issued cease-and-desist orders against Kalshi and Polymarket — with Arizona also filing criminal charges against Kalshi — the CFTC sued Arizona, Connecticut, and Illinois on April 4, 2026 to assert its exclusive jurisdiction over event-contract markets. The suits opened the federal-versus-state preemption fight that has since expanded to nine states.

  22. State action

    States coordinate enforcement against Kalshi and Polymarket sports event contracts

    Stateline reported that US states are coordinating enforcement arguments that Kalshi's and Polymarket's sports event contracts circumvent state sports-betting regulation. The action adds to existing cease-and-desist letters issued by multiple state gaming commissions throughout 2025 and directly tests CFTC federal preemption over state gaming law.

    Polymarket restricts EU access — official list: Belgium, Germany, France, Italy, Poland

    Polymarket's official restricted list for the EU covers Belgium, Germany, France, Italy, and Poland — Spain and the Netherlands are not on it. The restrictions reflect EU-level licensing frameworks that do not recognise CFTC DCM status as a substitute licence and follow Polymarket's July 2025 QCEX acquisition that re-opened US access.

    Robinhood closes MIAXdx acquisition, obtaining its own CFTC DCM + DCO (since rebranded Rothera Exchange)

    Robinhood closed its acquisition of MIAXdx, giving Robinhood Prediction Markets its own CFTC-registered Designated Contract Market and Derivatives Clearing Organisation. The structure reduces Robinhood's dependency on distributing KalshiEX-licensed contracts and positions it to list its own event contracts, bringing Robinhood's prediction-market product to structural parity with Kalshi.

    Federal Reserve FEDS paper: Kalshi CPI and FOMC markets outperform Bloomberg consensus

    The Federal Reserve's Finance and Economics Discussion Series published a working paper concluding that Kalshi's CPI and FOMC event-contract markets are competitive with — and in several sub-samples superior to — the Bloomberg economist consensus. The paper is the first peer-reviewed validation of a CFTC-regulated prediction market as a macroeconomic forecasting tool.

    Aristotle receives CFTC DCM + DCO designation for Aristotle Exchange — PredictIt stays on its no-action letter

    The CFTC granted Designated Contract Market and Derivatives Clearing Organisation designations to Aristotle, PredictIt's parent company, on September 5, 2025 — covering Aristotle Exchange, a legally separate platform that opened in October 2025 (Underdog acquired that regulatory clearance in March 2026). PredictIt itself was NOT upgraded: it continues to operate under its 2014 CFTC no-action letter, with a per-contract investment cap — pegged since CFTC Letter 25-20 (July 2025) to the FECA individual-contribution limit, currently $3,500 — and trader limits.

    The D.C. District Court ruled that election event contracts do not fall within the prohibited categories under CFTC Rule 40.11 and Section 5c(c)(5)(C) of the Commodity Exchange Act. The ruling allowed Kalshi to launch congressional-control contracts and became the foundational precedent for subsequent CFTC-regulated political event contracts across the industry.

Frequently asked questions

What is the current legal status of prediction markets in the United States?
Event contracts offered on CFTC-designated contract markets (Kalshi, Polymarket via QCEX, Robinhood via MIAXdx/Rothera Exchange, Fanatics Markets, Underdog Predict via Aristotle Exchange, FanDuel Predicts via CME Group) are federally regulated and available to US residents; PredictIt operates separately under CFTC no-action relief. The 2024 KalshiEx v. CFTC ruling confirmed election contracts are not in a prohibited category. State enforcement against sports event contracts remains active and unresolved — individual states have issued cease-and-desist letters arguing these contracts circumvent state sports-betting regulation, and federal preemption is being litigated.
Which prediction-market platform is most regulated in 2026?
Most platforms we cover are CFTC-regulated Designated Contract Markets (or distribute contracts listed on DCMs). Kalshi has the longest CFTC DCM operating history. Polymarket operates US access through its July 2025 QCEX acquisition. Robinhood received its own DCM + DCO in January 2026 via the MIAXdx acquisition (rebranded Rothera Exchange). PredictIt is the exception: it operates under a 2014 CFTC no-action letter, not a DCM registration — the reported January 2026 upgrade was erroneous. See individual reviews for regulatory detail.
Why is Opinion Trade not included in your news coverage as an affiliate partner?
Opinion Trade is an offshore, non-CFTC venue and is excluded from PredictorHQ's recommended-platform rankings under our Stage 9 compliance policy. We may cover news about the platform (such as the March 2026 OPN token generation event) for completeness, but we do not distribute affiliate links to it and do not recommend it to US residents.
