Kalshi Is Doubling Down on Sports at the Exact Moment Courts Are Split on Whether It Can Offer Them

The consensus view going into the summer of 2026 was that prediction markets had won the regulatory fight. Kalshi holds a federal license as a designated contract market (DCM - a CFTC-registered derivatives exchange). The Commodity Futures Trading Commission has been publicly defending what Chairman Michael Selig calls its "exclusive" jurisdiction over commodity derivatives markets. Multiple federal courts had blocked state enforcement. The theory was that a CFTC license was a shield.

The last month has dismantled that theory.

On July 7, U.S. District Judge Analisa Torres in Manhattan denied Kalshi's request for a preliminary injunction to block New York from enforcing its gambling laws against the platform. Torres went further than a simple denial: she assumed, without deciding, that Kalshi's sports-event contracts are "swaps" under the Commodity Exchange Act - the core premise of Kalshi's entire legal argument - and ruled against Kalshi anyway. Even if the contracts are federally regulated derivatives, she found, the CEA does not preempt New York's gambling laws.

Kalshi appealed the same day.

The Torres ruling is one data point in what has become a full-scale federal-state war over prediction markets. But it is the data point that changes the risk profile of the business Kalshi has spent the last 18 months building. Because Kalshi's fastest-growing, highest-volume, most heavily marketed product category is exactly the one states are targeting.

The legal split is real, and it goes the other way in more places

The Third Circuit in April 2026 became the first federal appeals court to side with Kalshi, holding in a 2-1 decision that the CEA preempts state gambling laws as applied to sports-related event contracts traded on a DCM. That was the ruling that made the "federal license is a shield" narrative plausible.

But the Ninth Circuit in May 2026 denied stays for Kalshi and Polymarket in Nevada and Washington state, letting state enforcement actions proceed. Judge Torres in July added a third circuit - the Second - to the column finding that states are not preempted. Courts in Arizona, Tennessee, and Maryland have gone both ways at the district level. The Sixth Circuit followed Torres's approach.

As of this writing, roughly 30 cases are moving through federal and state courts. The CFTC has sued six states since April - Arizona, Connecticut, Illinois, New York, Wisconsin, and Minnesota - and filed amicus briefs in others. Forty-one state attorneys general have formally urged the CFTC to recognize that jurisdiction over sports-related "event contracts" belongs to states.

This is not a settled legal question with one outlier judge. It is a circuit split heading toward the Supreme Court, and no one can say which way it will resolve.

The business built atop the legal gamble

While the courts divide, Kalshi has been executing one of the most aggressive growth pushes in financial services. June 2026 saw notional trading volume on Kalshi jump to $31 billion in total notional trading volume in June, a more than 70% increase from May. Across all platforms, combined volume topped $50 billion for the first time, driven almost entirely by the FIFA World Cup. Kalshi added 3 million new users during the tournament.

Sports event contracts account for approximately 90% of Kalshi's trading activity. Around two-thirds of Polymarket's volume is also sports. These are not small product lines being tested. This is the business.

The marketing spend reflects that. Kalshi partnered with the official prediction market sponsor of the World Cup, ran stadium co-branding ads, signed campaigns with Lionel Messi, Luka Modrić, José Mourinho, Timothée Chalamet, and J Balvin, and integrated with OpenAI's ChatGPT to surface contract odds when users search World Cup games. Over $1.2 billion has been traded on World Cup winner-picks contracts alone - a record for a single market on the platform.

From a pure growth standpoint, this is a masterclass in attention arbitrage. From a regulatory standpoint, it is a strategy that doubles down on the most legally exposed product at the moment courts are questioning whether the company can offer it.

The deeper issue is that the CFTC's current posture is itself a historical anomaly. Before the second Trump administration, the agency had been reluctant to approve markets resembling sports betting or gambling. The CFTC's sudden aggressive defense of exclusive jurisdiction - including direct lawsuits against state attorneys general - is a departure from its historical practice, not a continuation of it. Kalshi's legal team is banking on this new posture lasting long enough to win a Supreme Court case. That is a long time for any political wind to shift direction.

The incentive structure nobody is mapping

The participant ecology in this dispute looks like this:

• Kalshi and Polymarket are building a platform whose value proposition and revenue depend on operating in all 50 states without state-level licensing. Their federal registration is their moat. Every day a state enforces gambling law against them is a day they lose volume and user acquisition. Their incentive is to fight in federal court and win preemption everywhere.

• State governments are estimated to have lost more than $1 billion in taxes since prediction markets began offering sports events contracts, according to the American Gaming Association. States have spent decades building licensed sportsbook regimes, consumer protection frameworks, and tax structures. Prediction markets let users place what states view as identical wagers - on game winners, point spreads, and player statistics - while bypassing licensing, consumer protections, and taxes. The incentive for states to enforce is not just legal; it is fiscal and political.

• The CFTC has moved from passive observer to combative litigator. Chairman Selig has publicly warned states not to "undermine the agency's longstanding authority." But the agency's enforcement advisory from March 2026 revealed two disciplinary actions involving improper trading on Kalshi during 2025, suggesting the agency is not yet fully equipped to oversee these markets. The CFTC's incentive is to defend its regulatory turf and maintain jurisdiction over a growing asset class - but its capacity to actually regulate sports-event contracts at scale remains unproven.

• Traditional sportsbooks (DraftKings, FanDuel) are the incumbents being disrupted. Prediction market platforms are not paying state taxes, not following state advertising rules, not contributing to problem-gambling programs. The American Gaming Association is tracking the revenue loss. It should not be surprising that the industry is supporting state enforcement.

This is not a dispute about whether prediction markets provide useful price signals. The 2024 presidential election proved they can be more accurate than polling. The dispute is about who collects the toll, who enforces consumer protection, and who gets to define the boundary between a financial derivative and a bet.

The structural problem for the platforms

Kalshi CEO Tarek Mansour has dismissed state enforcement as the work of "gambling companies worried about losing their dominant, incumbent positions." That may describe part of the dynamic. But it misses the structural reality: the platforms are building a business whose growth depends on the outcome of a legal question that courts are actively dividing on.

The Third Circuit's 2-1 ruling for Kalshi carries weight, but it was a preliminary injunction decision - the court found only that Kalshi had a "reasonable chance" of prevailing, not that it had won on the merits. The Ninth Circuit's denial of stays and Judge Torres's July ruling go the other direction, and neither has been reversed.

Kalshi's appeal of the Torres decision is the next procedural step. If the Second Circuit follows Torres, the platform faces state-level enforcement in the largest financial market in the country. If the split persists, individual states will continue to litigate, and the platforms will face a patchwork of injunctions, licensing demands, and operational restrictions - the exact regulatory fragmentation the CEA was supposed to prevent.

The platforms are also betting that the CFTC's current aggressive posture will hold. Donald Trump Jr. serves as an adviser to both Kalshi and Polymarket, and his venture firm 1789 Capital is a significant investor in Polymarket. President Trump recently called it "critically important that the CFTC's exclusive authority over prediction markets is maintained." Political alignment is a powerful short-term force. It is also one election cycle away from changing.

Verdict

Kalshi is not a company that happens to have legal challenges. It is a company whose entire addressable market and growth strategy depend on winning a preemption argument that federal courts are divided on. The World Cup growth surge - 3 million new users, $31 billion in volume, a sports-heavy product mix - is remarkable as a business execution story. It is also a demonstration that the company is building exactly the revenue profile that states are determined to tax and regulate.

The CFTC's current defense of exclusive jurisdiction is real, but it is a political position as much as a legal one, and courts are not uniformly buying it. A federal license is not a shield when three circuits disagree about what the license means.

The question is not whether prediction markets have value. It is whether a business can be built on the assumption that the courts will eventually agree with its interpretation of a statute that Congress wrote in 2010 without thinking about sports betting at all.

If the CFTC's enforcement capacity grows, if the Supreme Court resolves the split in favor of federal preemption, and if the current political alignment holds, the narrative that the federal license is a shield may end up being right. But that requires winning in court, winning politically, and winning on enforcement - all at once. If any one of those three fails, the platforms face a regulatory environment they did not design and cannot control.

Systems that optimize for growth by riding jurisdictional ambiguity tend to find out, eventually, that ambiguity is not a strategy. It is a countdown.
