Supreme Court weighs prediction markets as Gen Z betting data reveals shift

The legal battle over who gets to regulate sports wagering in the United States has entered a new phase.

On 8 October, the NFL formally urged the Supreme Court to hear a case regarding the classification of prediction markets, according to reporting from The Hill. This request places the industry's central regulatory conflict directly in front of the highest court in the land. The core of the dispute hinges on a technical definition. Are platforms like Kalshi offering financial derivatives, or are they operating as illegal gambling operations? The answer determines whether the federal Commodity Futures Trading Commission has exclusive jurisdiction or if state gaming boards retain their traditional authority. The Hill reported on 8 October that the league is actively pushing for a ruling that would clarify this boundary.

Generation Z accounted for almost 50% of all online betting activity in July, according to a report from the Bank of America Institute released in September. That spike coincided with the height of the 2026 FIFA World Cup. For the first time, this generation outnumbered millennials in total betting volume, according to the same institute.

Generational shift in risk perception

Financial advisors are increasingly concerned about how young users categorize their wagers. Dan Egan, director of behavioral finance at Betterment, noted that sports betting increasingly appears alongside traditional investments on the same digital interfaces. This visual proximity helps drive a false association between wagering and long-term investing, he said.

“It's not an asset that grows with the economy, that kind of gets better as time goes on, that has a positive expected return, and that you can kind of sit back and not have to do anything with,” Egan told CNBC. He emphasized that the required behavior to manage wagers is highly active and fundamentally different from holding a diversified portfolio.

A survey of retail investors released by Betterment in August found that 66% of Gen Z investors participate in sports betting. In that same survey, 52% of Gen Z respondents said they moved money originally meant for investment to sports betting. Another 26% viewed wagering as a part of their long-term financial strategy, a perception that clinicians and financial experts widely dispute.

“It is more unusual for someone not to have, for example, a Kalshi account, DraftKings … than it is” to have such an account, said Cynthia Grant, vice president of clinical at Birches Health. “It's part of the experience of watching sports now.”

Grant’s observation highlights the normalization of these platforms among younger demographics. She noted that clinicians anecdotally report an increase in gambling problems among young people, particularly those who lose the most money and attempt to claw back their losses. This behavior puts users in deeper financial holes and is associated with greater risk for harmful mental health outcomes, according to CNBC's analysis of the survey data.

The prediction market loophole

The regulatory gray zone has been widened by the introduction of sports-related event contracts on prediction markets. These platforms claim their products are financial trades, not wagers. This distinction allowed them to expand access to additional states without legalized sportsbooks and to users under the age of 21, according to reporting by CNBC.

New York sued Kalshi in early October, alleging that the prediction market is illegal gambling, according to ABC7 Eyewitness News. Meanwhile, a bipartisan coalition of states has urged the Supreme Court to let them regulate prediction markets, as reported by Yahoo Finance on 7 October. The divergence in state approaches has created a patchwork of legal standards that national platforms must navigate.

Ars Technica reported on 8 October that a senator who previously tried to ban gambling on prediction markets is now working as a Kalshi lobbyist. This development highlights the growing influence of industry players in the policy process. The report highlighted the revolving door between legislative action and corporate advocacy in the fast-evolving sector.

Legal scholars and industry analysts point to a recent Sixth Circuit ruling that narrowed the definition of a swap and rejected the preemption of state sports-betting laws. JDSupra reported on 6 October that this decision reinforced the power of states to enforce their own gambling statutes. This ruling complicates the argument that federal jurisdiction should override state gaming boards, adding another layer to the complexity of the current legal situation.

Technology and infrastructure race

Alibaba Group Holding announced on 29 September that it had become an official technology and cloud partner of the NBA's Brooklyn Nets. The partnership, detailed by South China Morning Post, includes a multi-year strategic agreement. Under the deal, Alibaba will use its cloud infrastructure to power a new real-time 360-degree replay system at the Barclays Centre in New York City.

“The collaboration was announced on Monday under a multi-year strategic partnership between Alibaba and Brooklyn Sports & Entertainment,” according to a joint statement. The system is designed to deliver faster and more innovative broadcast replays starting in the upcoming 2026-27 NBA season. This move signals a broader trend of tech giants embedding themselves in the sports ecosystem beyond simple sponsorship deals.

The integration of advanced cloud computing and real-time analytics is not limited to broadcast quality. These same technologies are being used to refine the odds models and user experiences that drive betting volume. As the user base grows younger and more tech-savvy, the demand for high-performance platforms continues to rise. This technological arms race is proceeding independently of the legal battles unfolding in Washington and state capitols.

Financial stakes and market dynamics

Arthur Hayes, former BitMEX CEO and co-founder of Maelstrom, offered a different perspective on the broader tech boom that is fueling much of this infrastructure. In an interview with CNBC on 7 October, Hayes said humanity is “wasting multi-trillion dollars” on building AI data centers. He argued that this massive buildout would ultimately make computing power “extremely cheap and extremely plentiful.”

Hayes sees this overcapacity setting the stage for a downturn that could benefit crypto assets. “If you study financial history and you study every single major technological rollout, it always is overbuilt. There always is a crash, and there always is a bailout,” Hayes said. He suggested that investors who position for those bailouts stand to benefit, pointing to the aftermath of the 2008 financial crisis. While his comments focus on AI, the underlying infrastructure is shared with the high-frequency trading and data processing required by modern sports betting platforms.

The convergence of these factors creates a volatile environment. Young users are driving record volumes, often viewing their bets as investments. Regulators are split between federal and state authorities, with the Supreme Court poised to intervene. Meanwhile, technology companies are building out the necessary infrastructure, sometimes in jurisdictions where the legal status of their services remains unclear. The result is a sector that is growing rapidly in terms of user adoption and technological sophistication, but remains fundamentally unstable in terms of legal standing.

The next few months will be critical. The Supreme Court's decision on whether to take up the NFL's petition will set the tone for the industry's future. Until then, the patchwork of state laws and federal guidelines will continue to create a complex situation for operators. For the millions of Gen Z users who now make up half of the betting population, the risk is not just financial. It is also legal and regulatory, as the ground shifts beneath their feet. The industry is betting on a favorable outcome, but the odds are far from certain.
