NBA Names Kalshi and Polymarket Preferred Prediction Market Exchanges, Signs CFTC MOU
The NBA named Kalshi and Polymarket its preferred exchanges and signed a CFTC MOU on Oct. 26. Here is what the deal covers and what it leaves unresolved.
On Monday, October 26, 2026, the NBA did something it had avoided for years: it formally entered the prediction market business. The league named Kalshi and Polymarket its "Preferred Prediction Market Exchanges," expanded its DraftKings deal to cover prediction markets, and signed a Memorandum of Understanding with the Commodity Futures Trading Commission (CFTC) on the same day.
It is the biggest single-day shift in how a major American sports league treats event contracts, and it lands in the middle of a court fight over who gets to regulate them. Here is what the NBA actually announced, what the deal does and does not change, and why it matters for anyone trading or following NBA markets.
What the NBA Announced
According to the NBA's official announcement, the package has three parts:
- A CFTC MOU. The league and the federal regulator agreed to cooperate and share information on NBA-related prediction markets.
- Two "Preferred Prediction Market Exchanges." Kalshi and Polymarket each get rights to use NBA intellectual property, marketing rights, and promotional activations across media channels in the United States. Both also receive official NBA data from Sportradar, the league's Official Data Distribution Partner, to operate and settle authorized NBA-related markets.
- "Authorized Prediction Market Operators." DraftKings expanded its existing NBA agreement to include prediction markets and nationwide promotion. The league said it plans to extend its relationships with other current official sports betting partners, and others in the industry, "in the coming weeks."
The NBA also attached conditions. Per the league, its agreements with Kalshi and Polymarket include "limitations on permissible markets," "affirmative prohibitions on trading NBA event contracts by league and team personnel," and "information-sharing obligations relating to investigations and suspicious trading." Operators that join later must accept enhanced integrity obligations and market restrictions aligned with the NBA's latest sports betting restrictions.
"Protecting the integrity of the game is our top priority," said Scott Kaufman-Ross, the NBA's Head of Media Distribution & Partnerships, in the release.
The CFTC Memorandum of Understanding
The regulator confirmed its side in CFTC Release 9314-26. Under the MOU, the CFTC and NBA "will better share information by regularly communicating and discussing matters relating to integrity, as well as maintaining fair and transparent prediction markets."
CFTC Chairman Michael S. Selig said the NBA "joins the MLB and NHL in taking a responsible step toward protecting sports integrity and market participants from abuses in prediction markets like insider trading and fraud."
An MOU is not a regulation and not a license. It is an information-sharing agreement. It does not, by itself, settle whether sports event contracts are federally regulated swaps or state-regulated gambling, which is the question courts are currently fighting over.
How the NBA Fits Into the League Pattern
The NBA is the latest in a string of leagues that moved from skepticism to structured partnerships:
- NHL (October 22, 2025): The league announced multiyear U.S. agreements with both Kalshi and Polymarket, the first such deal among the major North American leagues.
- MLB (March 19, 2026): Baseball named Polymarket its prediction market exchange partner and signed an MOU with the CFTC that the agency called the first of its kind between the CFTC and a professional sports league.
- NBA (October 26, 2026): Two preferred exchanges, a CFTC MOU, and a sportsbook-operator tier that includes DraftKings.
The structure the NBA chose is closest to the NHL's two-exchange model, paired with the MLB-style regulator MOU. The league did not pick a single exclusive exchange.
The Holdout: The NFL
The NFL is now the outlier. As CNBC reported, the league said in an amicus brief to the Supreme Court earlier this month that sports-related event contracts should be regulated by the states rather than the CFTC. The brief, filed in No. 26-299, Flaherty v. Kalshi EX, LLC, supports New Jersey's request for Supreme Court review. CNBC reports the NFL also said it is not opposed to the markets, but thinks they need more guardrails, and that Kalshi said it had tried to work more closely with the league but the NFL had not engaged.
The NBA took a different public position on regulation. In an early-October interview with CNBC, Commissioner Adam Silver said: "From at least the NBA standpoint, we have roughly 40 different jurisdictions regulating us right now. So to have a consistent policy nationally, I think would be in our best interest."
That is a notable framing. A national framework is exactly what the CFTC-side argument in the litigation rests on, and the NBA's MOU effectively places the league alongside that approach, at least on integrity cooperation.
What Is Still Unresolved
The deal does not end the legal dispute. Per CNBC, platforms and the CFTC argue that event contracts are swaps regulated at the federal level, while many states argue the same contracts are sports betting subject to state law. Courts have issued conflicting rulings, and many observers expect the Supreme Court may ultimately need to decide.
Several practical questions are also open:
- Which contracts count as "permissible"? The NBA says there are limitations on permissible markets but its announcement does not list them. Which NBA contract types survive will determine how the new framework looks in practice.
- How does information-sharing work in practice? The release describes obligations relating to investigations and suspicious trading. The mechanics, thresholds, and any public reporting are not specified.
- Who joins next? The league said it plans to expand relationships with other current official sports betting partners and others in the industry in the coming weeks.
What It Means for NBA Market Traders
For people who trade or follow NBA markets, three things stand out:
- Settlement data gets official. Both preferred exchanges will use official NBA data from Sportradar to operate and settle authorized markets. For contracts that survive the new restrictions, that anchors resolution to the league's own data feed.
- Some contract types may disappear. Limitations on permissible markets and the personnel trading ban are designed to reduce integrity risk. Expect the menu of NBA contracts on regulated venues to be shaped by those restrictions.
- Insider-trading enforcement gets a path. With an MOU and information-sharing obligations, suspicious trading in NBA markets has a defined route from exchange to league to regulator.

Frequently Asked Questions
Which prediction markets are the NBA's preferred partners?
Kalshi and Polymarket. The NBA named both "Preferred Prediction Market Exchanges" on October 26, 2026. DraftKings was separately added as an authorized operator through an expansion of its existing NBA agreement.
Does the CFTC memorandum of understanding make NBA prediction markets legal everywhere?
No. The MOU is an information-sharing agreement between the CFTC and the NBA. It does not resolve the court disputes over whether sports event contracts are federal swaps or state-regulated gambling.
Can NBA players and team staff trade NBA event contracts?
Not on the preferred exchanges. The NBA says its agreements with Kalshi and Polymarket include affirmative prohibitions on trading NBA event contracts by league and team personnel.
Which leagues now have prediction market partnerships?
The NHL (Kalshi and Polymarket, October 2025), MLB (Polymarket, March 2026), and now the NBA (Kalshi and Polymarket, October 2026). The NFL has not announced a partnership and has filed a Supreme Court amicus brief supporting state regulation of sports event contracts.
Will there be more NBA partners?
The NBA said it plans to expand its relationships with other current official sports betting partners, and others in the industry, in the coming weeks. All such partnerships will carry enhanced integrity obligations.
The Bottom Line
The NBA's move turns a contested market category into one the league is now helping to design. Official data, personnel trading bans, and a regulator MOU are real integrity tools. What they do not do is resolve the federal-versus-state fight that the NFL's Supreme Court brief just sharpened. For traders, the practical takeaway is simple: NBA contracts on the preferred exchanges are about to become more standardized, more restricted, and more closely monitored.
