NFL tells the CFTC its prediction market rules fall significantly short
The league wants outright bans on contracts over officiating and player performance rather than case-by-case review, a 21-and-over floor, and prohibited-bettor lists—positions that put it at odds with both the Commission's draft and the leagues that partnered with the platforms.
What happened
The National Football League filed a comment letter, dated 27 July and signed by Brendon Plack, its senior vice president for public policy and government affairs, on the CFTC's proposed rule defining when event contracts are contrary to the public interest. The letter says the draft rules 'fall significantly short of protecting the integrity of sporting events' and asks the Commission to ban categories of contract outright—officiating decisions, individual player performance, and events 'knowable in advance' such as first plays or roster moves—rather than review them one by one. It also asks for a minimum age of 21, a longer pre-listing review window than the proposed ten days, mandatory league-specific prohibited-bettor lists, advertising limits and a bar on margined trading.
Why it matters
The June proposal, and the staff advisory that narrowed self-certification a fortnight ago, are the CFTC's attempt to draw the line between event contracts and gaming; the largest sports property in the United States has now told the Commission the line is in the wrong place. The NFL's stance diverges from MLB and the NHL, which have struck partnerships with Kalshi and Polymarket, and lands as sports contracts have become the platforms' largest volume driver and as Intercontinental Exchange deepens its investment in Polymarket. How the final rule treats sports categories will shape the economics of every listed venue.
What is not settled
The letter is dated 27 July and its caption records that it was submitted through Regulations.gov, but it is not yet readable at a public address. The Commission opened no comment file of its own for this proposal, routing submissions to Regulations.gov instead, and docket CFTC-2026-1189 had not published the letter a day after the deadline; the copy the reporting works from is privately hosted. The substantive question is also open. Whether the final rule adopts category bans or keeps case-by-case public interest review is unresolved, with tribal gaming regulators arguing in the same proceeding that sports contracts are already unlawful while much of the industry backs the draft as written.
Institutions in this story
-
Commodity Futures Trading Commission
Regulator
Proposed the public interest determinations rule on 12 June 2026 and now holds a comment file in which the largest sports property in the country says the draft is too weak, a fortnight after its own staff narrowed self-certification.
-
Kalshi
Exchange
Lists the sports contracts the letter would have banned outright, and has partnership arrangements with leagues that have not taken the NFL's position, so a category ban would fall hardest on its highest-volume book.
-
Polymarket
Exchange
Carries the same contract categories and has taken investment from Intercontinental Exchange, which makes the treatment of sports categories in the final rule a question about the value of that position as much as about market integrity.
On the record
NFL asks the CFTC to ban categories of sports event contract
The National Football League filed a comment letter on 27 July 2026 on the CFTC's proposed public interest determinations rule, saying the draft falls significantly short and asking the Commission to prohibit outright the categories it considers manipulable, including contracts on officiating, individual player performance and events knowable in advance, rather than review them case by case. It also asked for a minimum age of 21 and league-specific prohibited-bettor lists.
