The NBA has officially entered the prediction market industry, announcing partnerships with Kalshi and Polymarket while establishing new safeguards intended to protect the integrity of professional basketball.
The agreements, announced October 26, 2026, designate Kalshi and Polymarket as the league’s preferred prediction market exchanges. The NBA also signed an information sharing agreement with the Commodity Futures Trading Commission (CFTC), the federal agency responsible for overseeing derivatives markets.
The move comes less than two weeks after the NBA introduced new restrictions on certain player prop bets at licensed sportsbooks. Those restrictions did not automatically apply to prediction markets, creating a gap in the league’s efforts to prevent betting related manipulation.
The new agreements are intended to address that gap while giving the NBA greater influence over which basketball-related contracts its prediction market partners can offer.
What the NBA’s Agreements With Kalshi and Polymarket Include
The partnerships go beyond allowing Kalshi and Polymarket to advertise themselves as official NBA partners. Both companies will operate under agreements containing specific requirements related to market integrity, information sharing and insider trading.
Under the announced framework, the agreements include:
- Restrictions on NBA markets: The league will have a role in determining which basketball-related event contracts its partners can offer.
- Insider trading protections: NBA and team personnel will be prohibited from trading contracts involving NBA events.
- Suspicious trading investigations: Kalshi and Polymarket must cooperate with integrity investigations and share relevant information.
- Official NBA data: Both platforms will receive official league statistics through Sportradar, the NBA’s official data distribution partner.
- NBA branding rights: The exchanges can use league intellectual property and conduct authorized promotional activities in the United States.
Financial terms of the partnerships were not disclosed.
Scott Kaufman-Ross, the NBA’s head of media distribution and partnerships, said protecting the integrity of basketball remains the league’s primary concern.
The NBA has also expanded its existing partnership with DraftKings to include prediction markets and nationwide promotional activities. The league expects to announce additional agreements with other operators in the coming weeks.
New Rules Follow NBA Player Prop Betting Restrictions
The timing is significant because the NBA recently moved to restrict certain types of player prop bets following concerns about gambling related manipulation.
The league worked with its sportsbook partners to eliminate specific markets considered particularly vulnerable to abuse, including first-basket wagers and certain combinations of player statistical unders involving athletes expected to receive limited playing time.
These markets can create integrity concerns because a relatively small action by an individual player could influence the outcome of a wager.
For example, a player expected to appear for only a few minutes might have an unusually low statistical projection. Information about that player’s playing time, injury status or intended performance could provide someone with an unfair advantage.
Licensed sportsbooks participating in the NBA’s agreements were expected to implement the restrictions, but prediction market exchanges were not automatically covered.
Kalshi and Polymarket operate under a different regulatory structure from traditional sportsbooks, and the NBA previously lacked direct commercial agreements governing their basketball related contracts.
The October 26 announcement changes that relationship.
The NBA says its authorized prediction market partnerships will include restrictions aligned with its latest sportsbook policies. However, the announcement does not establish that every restricted market has already been removed from both exchanges.
NBA and CFTC Agree to Share Information
Alongside the commercial partnerships, the NBA signed a memorandum of understanding with the CFTC to improve cooperation involving suspicious trading and potential threats to basketball integrity.
The agreement establishes a framework for the two organizations to communicate about matters involving NBA prediction markets, including potential insider trading, fraud and other suspicious activity.
CFTC Chairman Michael S. Selig described the agreement as another step toward improving cooperation between federal regulators and professional sports leagues.
The NBA joins Major League Baseball and the National Hockey League in establishing similar arrangements with the agency.
The memorandum is an information-sharing agreement rather than a new federal regulation. It does not independently give the NBA authority to regulate every prediction market offering basketball contracts.
It also does not resolve the ongoing legal disagreement between federal regulators and state gambling authorities over sports prediction markets.
Why Prediction Markets Remain Controversial
Prediction markets allow customers to buy and sell contracts tied to the outcome of future events. In sports, those contracts can closely resemble traditional wagers.
For example, a customer might purchase a contract that pays $1 if a particular NBA team wins its next game. The contract’s purchase price determines the potential profit or loss.
Although the financial structure differs from a conventional sportsbook wager, both products allow customers to risk money on sporting outcomes.
The major difference is how the platforms are regulated.
Traditional online sportsbooks generally operate under state gambling licences and must comply with requirements involving consumer protections, advertising, responsible gambling and market integrity.
Federally regulated prediction market exchanges operate under the Commodity Exchange Act and CFTC oversight.
Several states argue that sports-related event contracts amount to gambling and should therefore be subject to state licensing requirements. Prediction market operators maintain that qualifying contracts fall under federal commodities law.
The disagreement has produced lawsuits and conflicting court decisions across the country.
The NBA’s new partnerships do not settle that dispute.
In fact, the league has indicated that it does not intend to take a position on whether state or federal authorities should ultimately control sports prediction markets.
Its immediate concern is ensuring that basketball-related contracts do not create unnecessary risks for players, teams or the integrity of competition.
NBA Takes a Different Approach From the NFL
The NBA’s decision also highlights a growing division among major professional sports leagues.
Major League Baseball and the NHL have already established relationships with prediction market companies, while the NFL has taken a more cautious position.
The NFL has raised concerns about the regulatory framework governing sports event contracts and has supported efforts to clarify the authority of state gambling regulators.
By contrast, the NBA is choosing to work directly with prediction market operators while legal challenges continue.
That approach gives the league a contractual mechanism to establish safeguards with participating exchanges rather than waiting for courts or regulators to settle the broader jurisdictional dispute.
However, the agreements also give prediction market companies valuable commercial benefits, including access to official league data, branding and promotional opportunities.
The partnerships therefore represent both an integrity initiative and a significant commercial expansion for the industry.
What the Agreements Mean for NBA Bettors
For customers who use Kalshi, Polymarket or other prediction market platforms, the most immediate potential change involves the types of NBA contracts available.
Markets covered by the league’s integrity restrictions may be modified or removed as operators implement their agreements.
Customers may also see more official NBA branding and league statistics incorporated into prediction market products.
The agreements do not mean that prediction markets are now licensed sportsbooks, nor do they guarantee that sports event contracts are legal in every state.
Players should also understand that an official NBA partnership does not eliminate the financial risks associated with trading sports contracts.
Prediction market contracts can lose their entire purchase value, and customers remain responsible for understanding the platform’s fees, settlement rules and applicable restrictions.
A Significant Step for the Future of Sports Prediction Markets
The NBA’s agreements with Kalshi and Polymarket represent another major step toward bringing prediction markets into mainstream professional sports.
Rather than treating prediction markets as competitors operating outside its existing sportsbook relationships, the league is establishing direct partnerships with additional integrity requirements.
The decision also demonstrates how quickly the distinction between traditional sports betting and prediction markets is becoming a central issue for professional sports leagues, gambling operators and regulators.
For now, the NBA has chosen to participate in the emerging industry while attempting to address the integrity risks associated with basketball related contracts.
Whether that approach becomes the standard across professional sports will depend partly on how effectively the new safeguards work and how courts ultimately resolve the ongoing dispute over prediction market regulation.
