A group of U.S. senators has intensified the push to block sports betting on federally regulated prediction markets after the Commodity Futures Trading Commission changed course on sports-event contracts in February 2026. The dispute matters beyond gambling policy: it tests whether sports wagers offered through exchanges such as Kalshi fall under federal derivatives law or remain subject to state and tribal gaming rules, a conflict that now sits at the center of Capitol Hill, the CFTC, and the courts.
⚠️
The immediate trigger was the CFTC’s February 4, 2026 withdrawal of a proposed event-contract rule and a staff sports-contract advisory.
That move became the catalyst for new Senate pressure to prohibit sports-related prediction markets, according to the CFTC and multiple Senate releases published in February 2026.
February 4, 2026 Reversal Reset the Federal Sports-Betting Debate
The core regulatory fact is clear. On February 4, 2026, the CFTC said it withdrew its proposed rule on event contracts and also withdrew prior staff guidance related to sports event contracts. In the agency’s own description, the earlier proposal had treated contracts involving gaming, war, terrorism, assassination, and unlawful activity as categories contrary to the public interest under the Commodity Exchange Act. That proposal had been issued in 2024, making the 2026 withdrawal a significant policy reversal rather than a routine procedural step.
That reversal gave senators opposing sports prediction markets a concrete legislative and oversight target. Senator Martin Heinrich said on February 24, 2026 that prediction-market platforms were enabling wagers on sporting events in ways that bypass state and tribal regulation. A separate February 13, 2026 Senate release led by Senators Adam Schiff and Catherine Cortez Masto said more than 20 Democratic senators urged CFTC Chair Michael Selig to maintain the agency’s prohibition on contracts involving gaming, including sports. Those statements do not by themselves create law, but they show a coordinated Senate campaign that is now moving from letters and pressure tactics toward legislation.
Key Federal Actions in the Prediction-Market Dispute
| Date | Institution | Action | Why It Matters |
|---|---|---|---|
| May 10, 2024 | CFTC | Proposed event-contract rule | Would have categorized gaming-related contracts as contrary to the public interest |
| February 4, 2026 | CFTC | Withdrew rule proposal and sports advisory | Opened the door to a broader federal argument for sports-event contracts |
| February 13, 2026 | U.S. Senators | Letter urging CFTC to prohibit gaming-related contracts | Showed organized Senate opposition |
| February 17, 2026 | CFTC | Court filing reaffirming exclusive jurisdiction | Asserted federal authority over prediction markets |
| March 12, 2026 | CFTC staff | Issued new prediction-markets advisory | Confirmed sports-related nuances remain under active review |

What 20-Plus Senators Are Trying to Stop
The Senate argument is not limited to consumer protection. It is also about jurisdiction. Heinrich’s February 24 release said sports-related prediction markets could bypass state law and tribal authority by presenting wagers as federally regulated derivatives. Schiff and Cortez Masto’s February 13 release framed the issue similarly, arguing that the CFTC should continue to bar contracts involving gaming, sports, terrorism, assassination, and related categories. In practical terms, senators are trying to stop exchanges from offering products that look like sportsbook bets while claiming federal preemption.
The CFTC has taken the opposite institutional position on jurisdiction. In a February 17, 2026 court filing announcement, the agency said it was reaffirming its exclusive jurisdiction over U.S. commodity derivatives markets, including event-contract markets commonly called prediction markets. That statement is central because any Senate bill aimed at banning sports betting on prediction markets would need to either amend the Commodity Exchange Act, direct the CFTC more explicitly, or otherwise narrow the legal space the agency says it controls.
How the Senate-CFTC Clash Escalated
May 2024: The CFTC proposed an event-contract rule that treated gaming-related contracts as contrary to the public interest.
January 11, 2026: Senators sought answers from the CFTC on insider trading, manipulation, and fraud in prediction markets.
February 4, 2026: The CFTC withdrew the proposed rule and prior sports-contract guidance.
February 13-24, 2026: Senate Democrats publicly pressed the CFTC to prohibit sports and other gaming-related contracts.
March 12, 2026: CFTC staff issued a fresh advisory that specifically noted sports-related event-contract nuances.
Why March 12, 2026 Guidance Kept Sports Contracts in Focus
Even after the February rollback, the CFTC did not signal that sports-event contracts were settled policy. On March 12, 2026, the agency’s Division of Market Oversight issued a new advisory on event contracts and said it discussed nuances with particular applicability to sports-related event contracts. That matters because it shows sports contracts remain a live regulatory category rather than a closed question. For lawmakers, that creates urgency. For exchanges, it preserves uncertainty. For state regulators and tribal operators, it raises the risk that federally listed contracts could expand before Congress acts.
There is also an enforcement backdrop. On February 25, 2026, the CFTC’s Division of Enforcement issued an advisory after two public enforcement cases involving misuse of nonpublic information and fraud tied to certain prediction markets traded on KalshiEX. The release cited a 2025 case in which Kalshi imposed a $2,246.36 penalty and a five-year suspension over improper trading by a political candidate on his own candidacy. That example involved politics rather than sports, but it gives senators a documented federal record of integrity risks inside prediction markets.

Integrity concerns are now part of the legislative case.
Senators cited insider-trading, manipulation, and fraud risks in January and February 2026 letters, while the CFTC published enforcement and market-oversight advisories in late February and mid-March 2026.
CFTC vs. States: Which Side Controls Sports Event Contracts?
The legal conflict is straightforward to describe and difficult to resolve. The CFTC says prediction markets fall within its exclusive jurisdiction over commodity derivatives. Opposing senators argue that sports-event contracts function as gambling products and should not be allowed to displace state gaming law or tribal compacts. Heinrich’s office explicitly said the federal approach could enable sports betting off tribal land, while Warren’s February 17, 2026 statement said the CFTC was trying to preempt state regulation on prediction markets.
Historical context strengthens the Senate case politically, even if not yet legally. The CFTC’s own 2024 proposal had already recognized gaming-related contracts as a public-interest problem. By comparison, the 2026 agency position is more permissive on jurisdiction and less categorical on sports. That shift is why senators are now moving from oversight letters to legislation. The likely legislative objective is not merely to criticize the CFTC, but to restore a bright-line federal prohibition on sports betting through prediction-market venues.
Three Paths as Congress Tests a Sports-Contract Ban
One path is statutory clarification. Congress could amend the Commodity Exchange Act to state plainly that sports-event contracts constitute gaming and are barred on CFTC-regulated venues. A second path is appropriations or oversight pressure that pushes the CFTC to reinstate a categorical prohibition through rulemaking. A third path is judicial resolution, where courts define the scope of federal authority before Congress finishes legislating. The February 17, 2026 CFTC court-filing announcement suggests the agency is prepared to defend broad federal jurisdiction, so litigation is not a side issue; it is part of the policy fight itself.
What is not yet public in the accessible record is a full bill text for a newly introduced March 2026 Senate measure specifically banning sports betting on prediction markets. Public Senate releases and CFTC documents clearly establish the policy campaign, the regulatory trigger, and the legal stakes. They do not, in the sources reviewed here, provide a complete introduced-bill text or official bill number for a new March 2026 ban measure. That distinction matters for accuracy.
