Kalshi removed athlete injury duration markets from its app on Tuesday, September 1, after the Commodity Futures Trading Commission asked the exchange to pull them, Sportico reported. The episode puts one of the most legally sensitive sports event-contract categories directly in the path of the CFTC’s pending rulemaking on prediction markets.

The affected contracts let users trade on when named athletes would return from injuries or become available to play. Sportico reported that Kalshi had offered markets tied to NBA players Luka Doncic and Anthony Edwards, New York Giants wide receiver Malik Nabers, tennis player Carlos Alcaraz, and other athletes. The outlet also reported, based on Kalshi’s published fee formula and earlier trading activity, that the exchange collected at least $8,000 in fees from those injury-linked markets.

What did Kalshi remove from its app?

Kalshi removed athlete injury duration and player availability markets, according to Sportico’s September report. Those markets asked users to take positions on a player’s injury status or return timeline, a category that differs from contracts tied to a team’s final score, season result, or game winner.

Kalshi had self-certified rules with the CFTC under internal labels including “INJURYRETURN,” Sportico reported. Self-certification is the process registered exchanges use to notify the CFTC that a new product complies with the Commodity Exchange Act and CFTC rules. Under CFTC Part 40 procedures, a designated contract market can list a self-certified contract unless the agency intervenes through the tools available under its regulations.

For much of the summer, Sportico reported, injury-linked markets visible in Kalshi’s app were limited to contracts tied to Nabers and Alcaraz. The exchange later added a wider set of NFL player availability markets before removing the category after the CFTC request reported by Sportico.

Why are athlete injury contracts a regulatory target?

The CFTC has already identified athlete injury contracts as a likely public-interest problem in its proposed prediction-market rule. In a June 12, 2026 Federal Register notice, cited as 91 FR 35806, the agency said contracts that settle solely by reference to the duration, severity, occurrence, or medical diagnosis of an injury to a specific athlete are likely to be found contrary to the public interest.

The proposal gave three reasons. First, the CFTC said athlete injury contracts could create financial incentives that encourage or facilitate physical harm to athletes. Second, it said settlement could depend on medical diagnoses, raising concerns about confidential medical information and the risk that sensitive information could be leaked or exploited by insiders. Third, it said settlement conditions based on physician diagnoses or injury reports do not provide a sufficiently objective, verifiable, and manipulation-resistant basis for contract settlement.

That language matters because it tracks the exact product category at issue in Kalshi’s removed markets. The CFTC proposal was not a final rule when Kalshi removed the contracts, but it put exchanges on notice that injury-specific sports markets sit near the center of the agency’s public-interest review.

Was this a formal enforcement action against Kalshi?

No formal CFTC enforcement action had been announced by the agency as of September 3, 2026. The CFTC’s public enforcement releases and orders did not include a published action against Kalshi over athlete injury markets, and Sportico described the removal as following an agency request rather than a public order.

That distinction is important for the market structure question. A public enforcement action would create an agency record and spell out the alleged violation. A request that results in a product being removed can change what users see on an exchange without producing the same public legal record.

Kalshi and the CFTC did not provide on-record comment to Sportico, according to the outlet. The available public record therefore shows two separate facts: Sportico reported that the CFTC asked Kalshi to remove the markets, and the CFTC’s June 12 Federal Register proposal independently identifies athlete injury contracts as likely contrary to the public interest.

What is the NFL’s position on these markets?

The NFL has objected to injury-linked prediction markets. NFL communications director Tim Schlittner told Sportico by email that the league “made it crystal clear we do not approve of these markets.”

The league’s objection fits its broader concern about betting products that turn player health or game administration into tradable outcomes. Athlete availability is already a sensitive area for professional sports leagues because injury information can move betting lines, fantasy contests, and roster decisions. A federally regulated exchange listing injury-duration contracts adds another venue where early or private medical information could have financial value.

The CFTC’s June proposal raised a similar concern, but in regulatory language. The agency focused on confidentiality of medical information, information leakage, and whether injury reports can support objective and manipulation-resistant settlement. For the NFL, the immediate issue is league integrity and player welfare. For the CFTC, the question is whether those contracts belong on registered derivatives markets at all.

How does this fit into the CFTC’s sports contract rulemaking?

The Kalshi removal came after the CFTC proposed a broader framework for event contracts involving enumerated activities, including sports. The June 12, 2026 proposal, 91 FR 35806, addressed several sports-related contract types that the agency said are likely to raise public-interest concerns.

Player injury contracts were one category. The proposal also discussed contracts tied to officiating decisions, discrete in-game actions by specific players or teams, and physical altercations. The agency distinguished those categories from contracts based on broader sports outcomes such as final scores, point differentials, or statistics compiled over the course of play.

The comment period for the June 12 proposal closed on July 27, 2026. As of September 3, 2026, the CFTC had not announced a final rule. Until a final rule is adopted, the June proposal remains the clearest public statement of how the agency views injury-based sports event contracts, but it is not itself the final regulatory text.

Why does this matter beyond one Kalshi product line?

The dispute shows how quickly sports event contracts can move from product launch to regulatory friction under the self-certification system. Registered exchanges can bring new contract types to market through filings that do not require the same public approval process as a full rulemaking. The CFTC can then respond through review, staff communications, public rulemaking, or enforcement, depending on the issue and the agency’s posture.

For prediction-market operators, athlete injury contracts are a test case with unusually high legal and reputational risk. They involve named players, private medical information, and settlement sources that may depend on reports produced outside the exchange’s control. Those features make the contracts different from a market on which team wins a game or which candidate wins an election.

For sports leagues, the issue is also commercial. Prediction exchanges have expanded into territory long occupied by sportsbooks, while arguing that federally regulated event contracts are different from state-regulated sports betting. Injury markets sharpen that conflict because they convert player health into a direct trading event.

What happens next?

The next regulatory milestone is the CFTC’s final action on its proposed prediction-market rule. The comment deadline was July 27, 2026, and the agency had not published a final rule or target adoption date as of September 3, 2026.

Until then, the public record leaves Kalshi’s removed injury markets in a narrow posture. Sportico reported that the contracts came down after a CFTC request. Separately, the CFTC’s proposed rule says player injury contracts are likely to be found contrary to the public interest. The final rulemaking will determine whether that position becomes binding across CFTC-registered exchanges.
