The Commodity Futures Trading Commission’s two June 2026 proposed rules — the Prediction Markets public-interest framework (RIN 3038-AF65) and the event-contract data-reporting amendments to Parts 15, 16 and 17 — replace nine years of no-action-letter tolerance with a codified federal regime for event contracts, with comments on the first closing July 27, 2026 and delisting of actively trading contracts explicitly on the table.

The CFTC published its Prediction Markets; Public Interest Determinations proposal in the Federal Register on June 12, 2026, amending Rule 40.11 of Title 17 to define when event contracts on “enumerated activities” — gaming, unlawful activity, terrorism, assassination and war — are contrary to the public interest (91 FR 35806). Two weeks later, on June 25, it proposed moving event-contract reporting out of the swaps-era rulebook and into the futures regime via a new §16.03 (CFTC Release 9261-26). Together the rules decide which prediction-market contracts may exist and how every surviving contract is surveilled. This analysis walks the rule text, compares how four regulatory regimes treat the same product, and sets out what registrants need filed — and by when.

Key Facts:

• RIN 3038-AF65 was published June 12, 2026, with the comment window closing July 27, 2026 — Federal Register 91 FR 35806
• The proposal establishes a three-step Rule 40.11 inquiry and contract-by-contract public-interest review that must commence within 10 days of listing and conclude within 100 days — WilmerHale client alert, June 18, 2026
• “Gaming” gets a three-prong definition: recreational purpose, governed by rules, and outcomes turning on participants’ luck, skill or athletic ability — Skadden, June 2026
• The Commission states its determinations “might entail the delisting of at least some event contracts that are actively trading” — NPRM preamble, via WilmerHale
• The June 25 reporting NPRM shifts fully collateralised event contracts from Parts 38, 39, 43 and 45 reporting into Parts 15–18, creating a new §16.03 “Covered Event Contracts” — CFTC Release 9261-26
• Both rules were proposed by a single commissioner: Chairman Michael Selig sits alone, with all four other seats vacant — Cleary Gottlieb commentary, June 2026
• The CFTC sued three states in spring 2026 to reassert exclusive jurisdiction over prediction markets — CFTC Release 9206-26

Methodology and sources

This analysis rests on the primary rule texts: the Prediction Markets NPRM as published at 91 FR 35806 (June 12, 2026), the CFTC’s accompanying releases 9249-26 and 9261-26, and the Commission’s state-litigation release 9206-26. Secondary interpretation draws on client alerts from WilmerHale (June 18, 2026), Skadden, Dechert and Greenberg Traurig, and reporting from Sportico on the sports-contract taxonomy. The jurisdictional scope is the United States (federal and state), the United Kingdom and the European Union; the window is June 10 through July 16, 2026. Caveat: both instruments are proposals — final rules can and usually do move — and the single-commissioner posture creates unusual legal-challenge surface that comment letters are already flagging.

What the two rules actually say

The public-interest proposal rewrites Rule 40.11, the provision the Commodity Exchange Act’s Special Rule (Section 5c(c)(5)(C)) hangs on. The NPRM sets a three-step inquiry: first, whether a listed product is an “event contract” at all — an agreement based on “an occurrence, extent of an occurrence, or contingency”; second, whether that contract “involves” one of the five enumerated activities, which the proposal answers by asking whether settlement is determined by an occurrence in that activity; third, whether the Commission, applying general public-interest factors plus activity-specific ones set out in a nine-page Appendix F, finds the contract contrary to the public interest after a review that must open within 10 days of listing and close within 100 days of it.

The gaming definition does the heaviest lifting. An activity is “gaming” if participants typically engage in it for recreation or to entertain others, it is governed by rules, and it includes measurable occurrences or outcomes that depend on participants’ luck, skill or athletic ability. That captures sports — but the taxonomy the Commission sketches is deliberately split: contracts on aggregate outcomes such as final scores, standings and season performance metrics are signalled as generally more likely to survive review, while contracts on player injuries, officiating decisions and discrete in-game actions are flagged as likely to fail it, per Sportico’s read of the proposal (Sportico). Terrorism, assassination and war contracts are described as “highly likely to be against the public interest” with no permissible examples offered.

What does the CFTC’s proposed Rule 40.11 framework mean in practice? It converts a discretionary veto the Commission has used sporadically since 2012 into a codified licensing filter for event contracts. Under the proposal, any contract touching gaming, unlawful activity, terrorism, assassination or war triggers a potential contract-by-contract review with fixed procedural clocks — commencement within 10 days of listing, conclusion within 100 — and published public-interest factors from Appendix F applied on the record (91 FR 35806, June 12, 2026). The rule takes effect 60 days after a final version is published, and the Commission has stated its determinations “might entail the delisting of at least some event contracts that are actively trading.” For designated contract markets, the practical effect is that listing certainty for sports-adjacent products no longer comes from a no-action letter; it comes from surviving a codified review whose factors are now public.

How four regimes treat the same product

Jurisdiction / Regulator	Instrument & date	Scope	Key requirement	Penalty / sanction
US federal (CFTC)	Rule 40.11 NPRM, RIN 3038-AF65, June 12, 2026; effective 60 days after final publication	Event contracts on five enumerated activities listed on DCMs/SEFs	Three-step inquiry; 10–100-day review clock; Appendix F factors; new §16.03 reporting	Listing prohibition; delisting of actively trading contracts
US states (NV, NJ, AZ gaming regulators)	Cease-and-desist orders, 2025–2026	Sports event contracts offered without state gaming licences	State licence or exit; contested as preempted — CFTC sued three states (Release 9206-26)	State civil enforcement; criminal referral exposure
UK (FCA / Gambling Commission)	FCA PS19/11, effective July 2, 2019; Gambling Act 2005	Binary options banned for retail; event betting routed to gambling licensing	Permanent retail prohibition on binaries; operators need a Gambling Commission licence	Unlimited FCA fines; licence revocation
EU (ESMA / national authorities)	ESMA MiFIR Article 40 measures, July 2, 2018, made permanent nationally	Binary options offered to retail clients	Prohibition on marketing, distribution and sale to retail	National administrative fines under MiFID II regimes

Sources: 91 FR 35806; CFTC Releases 9206-26, 9249-26, 9261-26; FCA PS19/11; ESMA (2018) binary-options measures. Last updated July 16, 2026.

The comparison exposes the arbitrage the CFTC is racing to close. The UK and EU resolved the “is it trading or is it betting” question years ago by splitting the product: binaries were banned for retail as financial instruments, and event wagering was pushed into gambling licensing. The United States is running the opposite experiment — folding event contracts into federal derivatives law and preempting the state gambling layer — which is why the same sports contract can simultaneously be a CFTC-supervised futures product in one filing and unlicensed gaming in a Nevada cease-and-desist. A US-listed venue that survives Rule 40.11 review ends up with nationwide distribution no state-licensed sportsbook enjoys; that asymmetry, more than any doctrinal point, is what keeps state regulators and the gaming industry in the fight, as our earlier analysis of the CFTC–state gaming split mapped.

“Under my leadership, the CFTC will no longer regulate market participants through a patchwork of no-action letters.”

Enforcement context: from Polymarket’s $1.4 million to suing the states

The enforcement arc explains the rulemaking. In January 2022, the CFTC ordered Polymarket’s operator to pay a $1.4 million civil monetary penalty for offering off-exchange event-based binary options without registration — the reference case for what happens to venues that skip the perimeter entirely. The 2023–2024 Kalshi congressional-control litigation then inverted the pressure: the Commission disapproved the contracts, lost in federal district court in Washington, and the defeat, as the WilmerHale team notes, is the direct ancestor of this NPRM — an agency codifying criteria after courts rejected its ad hoc reasoning (WilmerHale).

The third phase is federal-state. Through 2025 and 2026, gaming regulators in Nevada, New Jersey, Arizona and others issued cease-and-desist orders against federally registered venues listing sports contracts. The Commission answered with amicus filings from February 2026 and then, between April and June 2026, by suing three states outright to reassert exclusive jurisdiction under the Commodity Exchange Act (CFTC Release 9206-26). A final Rule 40.11 with published gaming criteria is, among other things, litigation infrastructure: it gives the preemption argument a codified federal standard to point at — a strategy consistent with the posture shift traced in our coverage of the CFTC’s no-deny settlement reversal.

What this means for brokers, exchanges and compliance teams

For designated contract markets and swap execution facilities, the operational change is twofold. Listing risk becomes procedural: any enumerated-activity contract carries a 10-to-100-day review exposure with delisting — including of actively trading products — as a stated outcome, so product pipelines need Appendix F analyses attached before self-certification, not after. Reporting becomes futures-native: the June 25 NPRM moves fully collateralised event contracts out of Parts 38, 39, 43 and 45 and into the Parts 15–18 regime, meaning large-trader reporting, position accountability and the new §16.03 apply.

Futures commission merchants, clearing members and foreign brokers inherit that reporting directly — the NPRM names all three as reporting parties, which pulls firms that never touched prediction markets operationally into event-contract data plumbing the moment a client trades one. Fund managers holding event-contract positions should assume large-trader visibility. Compliance calendars have one hard date: comments on the public-interest rule close July 27, 2026, and the reporting proposal runs on its own parallel window; firms with sports-adjacent listings have every incentive to put the aggregate-versus-discrete distinction on the record now, because the preamble’s taxonomy will harden into review outcomes later.

What is a “covered event contract” under the reporting proposal? It is a fully collateralised event contract listed on a reporting market — the product category the CFTC has handled through staff no-action letters since 2017 — which would now be reported under the futures rulebook rather than the swaps one. Concretely, the June 25, 2026 NPRM creates a new §16.03 and routes these contracts through §§16.00 and 16.01 market-data reporting, Part 17 large-trader position reporting and Part 18 special calls, in place of the Part 38, 39, 43 and 45 provisions that previously applied, per CFTC Release 9261-26. Reporting markets, futures commission merchants, clearing members and foreign brokers are all named reporting parties. The practical consequence: event-contract venues get surveillance parity with futures exchanges, and the Commission gains position-level visibility it never had over prediction markets during the entire no-action era.

The forward view: three clocks running

Three timelines now interact. The rulemaking clock: comments close July 27, 2026, and a final rule taking effect 60 days after publication puts the earliest fully operative regime in late 2026 — with the retroactivity footnote flagged by WilmerHale (contracts listed before the effective date may sit awkwardly against the 10-day commencement window) as an obvious target for both comment letters and litigation. The litigation clock: the Commission’s suits against three states, and the state cases moving toward the Supreme Court, will decide whether preemption holds regardless of what the final rule says. And the political clock: both proposals issued on the vote of a single commissioner, because the four other seats are vacant — a fact commenters will use to question the durability, and challengers the validity, of whatever is finalised. The sports-league dimension is unresolved too: the NCAA and NFL have pushed for narrower in-game markets, and the aggregate-versus-discrete line in the final rule will effectively write the product catalogue for every US event-contract venue. The regulatory-structure backdrop — a CFTC simultaneously absorbing crypto spot-market authority under the CLARITY Act’s SEC–CFTC split and re-scoping prop-trading oversight — means event contracts are one queue in a crowded rule factory, and slippage is the base case.

FAQ

What is the CFTC’s prediction markets proposed rule?

RIN 3038-AF65, published June 12, 2026 at 91 FR 35806, amends Rule 40.11 to codify when event contracts involving gaming, unlawful activity, terrorism, assassination or war are contrary to the public interest — using a three-step inquiry, activity-specific factors in a new Appendix F, and a review that opens within 10 days of listing and closes within 100.

When do comments on the CFTC event-contract rules close?

Comments on the public-interest proposal close July 27, 2026. The June 25 data-reporting NPRM (Parts 15, 16 and 17) runs on its own comment window announced in CFTC Release 9261-26.

Are sports prediction markets being banned?

No — the proposal distinguishes rather than prohibits. Contracts on aggregate outcomes (final scores, standings, season metrics) are signalled as generally more likely to survive public-interest review; contracts on injuries, officiating decisions and discrete in-game actions are likely to fail it. High-school sports and casino-game contracts sit on the prohibited side of the taxonomy.

What is the new §16.03 reporting requirement?

The June 25 NPRM would create §16.03 “Covered Event Contracts”, moving fully collateralised event contracts from Parts 38, 39, 43 and 45 reporting into the Parts 15–18 futures regime — bringing reporting markets, futures commission merchants, clearing members and foreign brokers into event-contract data reporting.

Can the CFTC delist contracts that are already trading?

The Commission preliminarily believes finalisation “might entail the delisting of at least some event contracts that are actively trading” — though client alerts flag a timing ambiguity for contracts listed before the rule’s effective date, given the 10-day review-commencement window.

How do the UK and EU regulate the same products?

Both route them away from financial-markets treatment for retail: the FCA permanently banned retail binary options in PS19/11 (July 2019) and event betting requires a Gambling Commission licence, while ESMA’s 2018 MiFIR Article 40 measures — made permanent by national authorities — prohibit retail binary options across the EU.

Why did only one commissioner vote on these rules?

All four non-chair CFTC seats are vacant, leaving Chairman Michael Selig as the sole sitting commissioner — a posture commenters are expected to raise against the durability of any final rule.
