Kalshi CEO says state-led oversight of U.S. prediction markets would push them out

Introduction

Kalshi’s chief executive, Tarek Mansour, told attendees at DC Fintech Week that the future of U.S. prediction markets hinges not on a simple state‑versus‑federal showdown, but on whether the industry can remain domestically viable. A split among federal appellate courts – with one decision favoring Kalshi’s view and two siding with state gambling regulators – has set the stage for a potential Supreme Court review. Mansour argues that state‑led oversight would push firms offshore, undermining the nascent market’s growth.

1. The regulatory tug‑of‑war

Prediction markets sit at the intersection of commodity trading and gambling law. Kalshi operates under the Commodity Futures Trading Commission (CFTC), which classifies its event contracts as commodity derivatives. Several states, however, contend that contracts tied to sports outcomes constitute illegal wagering and should fall under state gambling authorities. Recent appellate rulings illustrate the divide:

• Federal appellate split – One circuit upheld the CFTC’s jurisdiction, while two others affirmed state authority over sports‑related contracts.
• Supreme Court petition – New Jersey has asked the high court to resolve the conflict, drawing interest from industry groups and the NFL.

Mansour’s stance is that a fragmented regulatory landscape would erode the market’s economic rationale, prompting firms to seek jurisdictions with clear, federal‑level oversight.

2. Why offshore relocation matters

If state regulators gain primacy, prediction‑market platforms could face:

• Licensing hurdles – Multiple state licenses, each with its own compliance regime, would raise operational costs.
• Legal uncertainty – Divergent state rulings could expose firms to contradictory obligations, increasing litigation risk.
• Capital flight – Investors may prefer jurisdictions where a single regulator (e.g., the CFTC) provides a predictable framework, potentially shifting liquidity away from U.S. venues.

Mansour likens the situation to the early days of online sports betting, where a patchwork of state laws stifled national growth until a federal framework emerged. He suggests that without a unified approach, the U.S. could lose its competitive edge to overseas exchanges that already operate under clearer commodity‑derivative rules.

3. The CFTC’s response and industry implications

In parallel with the court battles, the CFTC has accelerated rulemaking aimed at formally incorporating event contracts into the definition of swaps. Recent proposals would:

• Clarify that prediction‑market contracts are swaps – placing them squarely under CFTC supervision.
• Preempt state gambling claims – by establishing a federal exemption for contracts that meet commodity‑derivative criteria.

If adopted, these rules could solidify the regulatory foundation for platforms like Kalshi, but they also risk provoking further state challenges. The outcome will shape not only prediction markets but also related products such as crypto‑based derivatives, where jurisdictional clarity remains a hotly debated issue.

4. Practical takeaways for market participants

• Monitor court developments – The Supreme Court’s decision, if granted, will set a precedent for the entire industry.
• Assess jurisdictional risk – Firms should evaluate the cost of operating under a multi‑state regime versus relocating to a jurisdiction with a single, federal regulator.
• Engage with policymakers – Industry groups can influence rulemaking by highlighting the economic benefits of a unified regulatory approach.
• Diversify compliance strategies – Preparing for both federal and state oversight can mitigate disruption if the legal landscape shifts.

Conclusion

Mansour’s warning underscores a pivotal moment for U.S. prediction markets. The legal battle is less about who regulates and more about whether the sector can survive domestically. A federal‑centric framework would preserve liquidity and innovation, while a state‑driven model risks pushing firms offshore, fragmenting the market, and ceding leadership to foreign exchanges. Stakeholders should stay attuned to the evolving jurisprudence and regulatory proposals, as the next few months could determine the industry’s geographic destiny.
