The memorandum of understanding (MOU) is non-binding, meaning neither party faces legally enforceable obligations under it. What it does create is a structured channel for cooperation: monthly meetings between designated representatives from each organization, discretionary information exchange, and joint protocols for flagging suspicious trading activity on platforms such as Kalshi and Polymarket. Both platforms already hold commercial sponsorship deals with the NHL, struck in October 2025, which made the league the first major U.S. sports property to formally partner with prediction market exchanges. The MLB agreement that this MOU mirrors included CFTC access to official Sportradar game data as part of the information-sharing structure; whether the NHL deal extends equivalent official data access has not been confirmed.

CFTC Chairman Michael Selig has been direct about why this framework is necessary. "The biggest issue that comes up is manipulation and insider trading in these markets," he said at a FINRA conference on May 12. "We need to act quickly to put rules in place to make sure we've got integrity in these markets." The concrete stakes of that concern came into focus when federal prosecutors indicted a U.S. Army sergeant for allegedly trading on Polymarket using non-public information about a military operation. Selig has cited that case as his flagship example of the manipulation risk the MOU framework is designed to address. Selig also acknowledged that the market's growth has outpaced conventional regulatory expectations. "Of course I did not expect to be overseeing derivatives on sports," he said, "but here we are." He confirmed the agency is in active discussions with every major U.S. professional sports league, including the NBA and NFL, to pursue similar agreements. The NHL's MOU, like MLB's before it, mirrors a template the CFTC appears to be rolling out systematically.

The scale of the market now under that oversight is substantial. Kalshi and Polymarket together have recorded more than $150 billion in combined lifetime trading volume through April 2026, according to industry sources including SI.com, DeFiRate, Laika Labs, and The Motley Fool. Across all regulated prediction market platforms, industry-wide notional trading volume exceeds $162.65 billion, according to figures compiled by DLA Piper.

Kalshi processed roughly $12.35 billion in March alone, with sports contracts accounting for 87 percent of that figure. Polymarket, which operates on the Polygon blockchain and settles all positions using pUSD (an ERC-20 token backed by USDC), recorded $26.2 billion in on-chain volume in the first quarter of 2026, a figure more than 90 percent higher than the prior quarter. A single-day record of $425 million was set in February 2026, surpassing even the platform's volume during the November 2024 U.S. presidential election. Kalshi was separately valued at $22 billion following a $1 billion Series F funding round in May 2026.

The NHL's willingness to engage the regulatory process rather than resist it reflects a deliberate strategy. Keith Wachtel, the league's President of Business, put it plainly: "From the beginning, we've always believed in the viability of the prediction markets, in large part because they are federally regulated. That was always something that gave us comfort. We believe we are better off being part of the system than not."

That federal system rests on a foundation established in 2023, when the CFTC approved Kalshi's application to list election event contracts. That decision classified prediction market instruments as federally regulated derivatives rather than gambling products, opening the door to broader event-contract expansion and establishing why the CFTC, rather than state gambling regulators, holds primary jurisdiction over these platforms.

The federal framework is now under direct legal challenge from approximately five to six U.S. states. The CFTC has filed suits against Illinois, Arizona, Connecticut, and others that have attempted to classify prediction market platforms as illegal gambling operations under state law. A Third Circuit court ruling in April 2026, in the case KalshiEx LLC v. Flaherty, sided with the federal position, holding that the Commodity Exchange Act preempts New Jersey's gambling statutes. The enforcement picture extends beyond civil regulatory action: the U.S. Department of Justice has signaled willingness to pursue criminal prosecutions for insider trading on sports event contracts under CEA Section 6(c)(1) and Regulation 180.1, a dimension of liability that is material for platform operators and market participants alike. Seven bills addressing prediction market regulation are currently pending in Congress, ranging from prohibition to clearer federal authorization.

Outside the United States, the regulatory picture is considerably more complicated. In India, both Kalshi and Polymarket began accepting users without local licensing, timed to coincide with the IPL cricket season. The Indian government has moved to formally block both platforms after they continued operating despite informal restrictions. The legal argument that makes these platforms viable in the U.S., specifically their classification as federally regulated derivatives rather than gambling products, carries no weight under the Public Gambling Act or India's online gaming rules. The same tension applies in Pakistan and Bangladesh. For developers building on Polygon or integrating Polymarket's API, infrastructure-level access restrictions in South Asia are a live risk that requires jurisdiction-specific legal review.

In Africa, the picture is more nascent but moving quickly. Luno launched prediction markets in Nigeria and South Africa in March 2026, partnering with U.S. provider Limitless to offer USDC-denominated outcome contracts on crypto asset prices, covering Bitcoin, Ethereum, Solana, Dogecoin, and XRP, with a minimum stake of 3 USDC. These are crypto price contracts, not sports event contracts, and are distinct from the sports-focused instruments at the center of the NHL-CFTC agreement. Ayotunde Alabi, CEO of Luno Nigeria, described the launch as a natural extension of how his users already operate: "Prediction Markets are a natural evolution of how our customers already engage with cryptocurrency."

The appetite for such products in Nigeria reflects a market of substantial scale. The country received $92.1 billion in total on-chain value in 2026, recorded over $2.4 billion in monthly on-chain volume, and ranked sixth globally in the Chainalysis 2025 Crypto Adoption Index. Local platforms are also emerging, including Predicta Markets, which is targeting T20 World Cup and Nigerian election contracts. Regulatory clarity remains thin: Nigeria's gaming authority has already classified at least one local competitor, Bayse Markets, as an illegal operator.

The NHL-CFTC agreement itself will not set law in Lagos or Mumbai. But the frameworks being established in the U.S., covering data sharing between leagues and regulators, exchange-level KYC obligations, and criminal liability for insider trading on sports contracts, are now being built into the institutional architecture of the largest prediction market ecosystem in the world by trading volume. Regulators in South Africa and Nigeria are both actively updating digital asset rules in 2026. How closely they follow the American template will matter a great deal to the next wave of platforms trying to serve those markets.
