NBA Signs CFTC Prediction Market Pact, Names Kalshi and Polymarket as Preferred Exchanges
The National Basketball Association has become the third major US sports league to sign a memorandum of understanding with the Commodity Futures Trading Commission, formalising a framework for information sharing and integrity protection across prediction markets. The league has also named two platforms as its "preferred prediction market exchanges," signalling that regulated event contracts tied to professional sports are moving from a legal grey area into structured, supervised territory. For accounting firms and CFOs with clients active in this space, the shift has real implications for how prediction market revenue, positions, and counterparty relationships get reported and audited.
What the CFTC and NBA Actually Agreed To
Under the memorandum of understanding, the CFTC and the NBA commit to sharing information and maintaining open lines of communication with the shared goal of preserving game integrity while prediction markets on league events continue to grow. Neither party is creating new law here. An MOU is an administrative coordination tool, not a statutory mandate. What it does do is establish a direct channel between the regulator and the league so that suspicious trading patterns, potential insider activity, and integrity concerns can be escalated without waiting for a formal enforcement referral.
The Preferred Exchange Designation
The NBA's decision to name two specific platforms as preferred prediction market exchanges is commercially significant. In its own statement, the league framed the partnerships as a way to build a framework that creates new fan engagement opportunities while ensuring appropriate safeguards. Scott Kaufman-Ross, the NBA's head of media distribution and partnerships, described the move as an important step in working constructively with both regulators and operators. That language matters: it positions the league not as a passive data source for the CFTC but as an active participant in shaping how these markets function.
Which Leagues Have Signed, and Who Has Not
The NBA is the third league to reach this kind of agreement with the CFTC. Two other major US sports leagues signed comparable MOUs earlier in 2026, though the source does not name them. Notably absent is the National Football League. The NFL has taken a sharply different position, pressing the CFTC for stricter rules on game integrity, consumer safety, and insider trading controls rather than entering a cooperative information-sharing arrangement. The NFL has also filed an amicus brief with the US Supreme Court arguing that sports prediction contracts constitute gambling and should therefore fall under state jurisdiction rather than federal commodity law. That filing crystallises a fundamental dispute that is now heading toward potential Supreme Court review.
The Federal vs. State Jurisdiction Battle
The CFTC's position is that most contracts traded on prediction market platforms are swaps, which places them squarely within its exclusive federal jurisdiction under the Commodity Exchange Act. Several US states disagree. State gaming regulators have argued that prediction market operators are running unlicensed gambling businesses that violate state law and, critically, that they are avoiding the tax obligations that apply to licensed gaming operators under state codes.
Why the Supreme Court Question Matters
New Jersey has asked the US Supreme Court to take up the jurisdictional question. If the Court agrees to hear the case, the resulting ruling could redraw the entire regulatory map for prediction markets in the US. A decision favouring state authority would expose platform operators to a patchwork of fifty different licensing regimes, tax treatments, and compliance requirements. A ruling cementing CFTC exclusivity would, conversely, give the industry a single federal framework but one that does not currently include state gaming tax revenue. For firms advising clients who operate or invest in prediction market infrastructure, the outcome will determine which regulatory filings matter, which tax obligations apply, and how contracts should be classified on the balance sheet.
This jurisdictional uncertainty is directly relevant when choosing crypto accounting software or broader digital asset accounting software capable of handling event contract positions. Classification drives everything: whether a prediction market position is accounted for as a derivative, a gambling liability, or a financial instrument under US GAAP depends in part on how the underlying contract is legally characterised.
Insider Trading: A Persistent Integrity Problem
The MOU's integrity-protection language is not hypothetical. Two enforcement cases illustrate exactly why this channel between regulator and league is needed.
The Army Soldier Case
In April 2026, an active-duty US Army soldier was charged with using confidential government information to place bets on a prediction market platform ahead of the announced capture of former Venezuelan President Nicolás Maduro. The case demonstrates that material non-public information in prediction markets is not limited to corporate earnings or political policy: it can extend to military and intelligence activity with direct market-moving potential.
The White House Teleprompter Settlement
A former White House teleprompter operator agreed to pay more than $172,000 to settle charges that he used advance access to presidential speeches to profit on a prediction market platform before the content became public. The CFTC treated this as a manipulation and insider trading matter under its commodity law authority, not as a gaming enforcement action. That framing is itself a statement about how the regulator views these contracts.
What the Platforms Are Doing
Both named preferred exchanges have disclosed steps they have taken to address insider trading risk, including mandatory employment verification for traders participating in sensitive markets. The NBA-CFTC MOU creates a formal structure for the league to flag players, coaches, staff, and other insiders whose trading activity looks anomalous, giving the CFTC a sports-intelligence layer it previously lacked.
Accounting and Reporting Implications for B2B Clients
Accounting firms, auditors, and CFOs with exposure to prediction market platforms, sports tech clients, or digital asset fund managers need to track several threads coming out of this development.
Contract Classification Under US GAAP
Prediction market positions can be classified differently depending on their legal characterisation. If the CFTC's swap jurisdiction holds, contracts may need to be evaluated under ASC 815 (Derivatives and Hedging) or potentially ASC 321/323 for investment treatment. If state gaming law applies, an entirely different accounting and tax regime could govern the same economic position. Firms should not assume current treatment is stable until the Supreme Court question is resolved. Document your reasoning now, and flag the contingency in any audit or review engagement involving prediction market positions.
Tax Treatment of Prediction Market Gains
The state-versus-federal dispute also has a direct tax dimension. States that classify prediction market contracts as gambling would apply gaming tax rules, potentially including withholding obligations and specific form requirements. Federal treatment under CFTC jurisdiction would more likely follow commodity contract or swap rules. Until there is clarity, any client with material prediction market exposure should be tracking gains and losses on a position-by-position basis so that the records can support either tax treatment. Robust crypto bookkeeping software or digital asset accounting software that captures trade-level data with timestamps, counterparty identifiers, and contract terms is the baseline requirement here.
AML and KYC Considerations
The two enforcement cases above are a reminder that prediction market platforms have AML exposure, not just gaming compliance exposure. If clients are operating or investing in platforms that handle large volumes of event contracts, the CFTC's growing supervisory role means that transaction monitoring, suspicious activity reporting, and customer due diligence standards are going to tighten. Review engagement letters and scope agreements to ensure AML advisory work is properly captured.
The "Preferred Exchange" Label and Due Diligence
The NBA's designation of two platforms as preferred exchanges is not a regulatory endorsement and carries no statutory weight. Firms auditing clients that use or invest in these platforms should not treat the label as a substitute for independent due diligence on financial controls, custody arrangements, and counterparty risk. Run your own assessment. The MOU between the NBA and the CFTC is an integrity coordination tool, not a seal of approval on the platforms' financial soundness.
What to Watch Next
Three developments will determine how this market structure evolves. First, watch for the US Supreme Court's decision on whether to grant certiorari in the New Jersey case challenging CFTC jurisdiction. An acceptance alone will move markets and force a re-evaluation of prediction market accounting positions. Second, track whether the NFL eventually signs its own MOU or continues to push for stricter federal rules, since its stance directly influences how the CFTC calibrates its oversight posture. Third, monitor whether other leagues that have already signed their own agreements begin disclosing specific data-sharing protocols, because that level of operational detail would give compliance teams something concrete to build internal controls around.
For firms already advising clients in adjacent digital asset spaces, the prediction market integrity framework being built here is a preview of the kind of layered, multi-regulator compliance environment that is becoming standard across the broader digital asset industry. The tools and workflows being developed for Kalshi's integration with stablecoin infrastructure are directly relevant to understanding how these preferred exchange relationships will function operationally, and our earlier analysis of the Pentagon's ban on insider betting on military operations shows the same insider-trading concern now embedded in the NBA-CFTC MOU playing out at the highest levels of government.
Frequently Asked Questions
Does the NBA-CFTC MOU change the legal status of prediction markets?
No. An MOU is an administrative coordination agreement, not legislation or rulemaking. It creates a communication and information-sharing channel between the league and the regulator but does not resolve the underlying federal-versus-state jurisdictional dispute or alter the legal treatment of prediction market contracts.
How should prediction market positions be classified on a US GAAP balance sheet?
Classification depends on the legal characterisation of the contract. Under the CFTC's view that these are swaps, ASC 815 is the most likely starting point. If state gaming law ultimately prevails, a different framework may apply. Given the live Supreme Court question, firms should document their classification rationale carefully and revisit it as the legal landscape develops.
What are the tax risks for clients with prediction market exposure?
The federal-state dispute means that applicable tax rules are genuinely unsettled. State gaming tax treatment differs significantly from federal commodity or swap tax treatment. Clients should maintain granular position-level records so that gains and losses can be restated under whichever regime ultimately applies, and should consider seeking a tax opinion if exposure is material.
Does the "preferred exchange" designation carry regulatory or financial weight?
No. The NBA's designation of two platforms as preferred exchanges is a commercial and reputational arrangement, not a regulatory endorsement. It does not signal CFTC approval of those platforms' financial controls, custody practices, or capital adequacy. Independent due diligence remains necessary for any audit or advisory engagement.
What does the insider trading history in prediction markets mean for AML compliance?
The two insider trading enforcement actions cited in this development confirm that prediction markets carry material AML and market manipulation risk. Firms advising clients that operate, invest in, or use prediction market platforms should assess whether existing transaction monitoring and suspicious activity reporting frameworks are adequate for the specific risk profile of event contract trading.
