Kalshi’s prediction market fight reaches new phase as Ninth Circuit weighs Nevada ban
Federal appeals court hears clash over state ban
A long‑running fight over how U.S. prediction markets should be policed moved forward on April 17, when the U.S. Court of Appeals for the Ninth Circuit heard arguments in a dispute between Kalshi and Nevada officials.
At issue is a Nevada district court order that bars Kalshi from offering certain event‑based contracts in the state unless it secures a local gaming license. Kalshi is asking the Ninth Circuit to overturn that ruling and confirm that its products fall under federal financial regulation rather than state gambling rules.
Core question: financial derivative or gambling product?
The appeal turns on a basic legal question: whether event contracts on real‑world outcomes are “swaps” governed by the federal Commodity Exchange Act, or wagers that states can regulate as gambling.
Kalshi argues its contracts are swaps, a type of derivative subject to the exclusive jurisdiction of the Commodity Futures Trading Commission (CFTC). CFTC chair Michael Selig has backed that view in other disputes with state regulators, framing such products as part of the federal derivatives markets.
States including Nevada and Ohio counter that, when users pay to predict real‑world outcomes and can profit if they are right, the activity is functionally no different from traditional betting and should require a gambling license.
Conflicting rulings across the country
During the Ninth Circuit hearing, both judges and lawyers acknowledged a growing patchwork of enforcement actions and rulings against event‑based platforms around the country, including criminal charges previously brought in Arizona.
That same Arizona dispute produced a conflicting outcome at the federal level. A federal court there recently blocked state authorities from applying Arizona’s gambling laws to Kalshi’s contracts, a direct contrast with the Nevada court’s position.
Similar splits are emerging elsewhere:
- a federal appeals court ruled in Kalshi’s favor against New Jersey regulators on April 6, concluding that federal law likely preempts the state’s attempt to regulate its markets;
- a Nevada judge has extended a ban on the platform’s sports‑linked contracts, keeping them off the market pending further review.
Kalshi attorney Colleen Sinzdak told the Ninth Circuit that such overlapping and inconsistent decisions from state and federal courts on the same core questions are creating deep legal uncertainty.
Supreme Court now in view
The widening divide between state and federal rulings has raised expectations that the U.S. Supreme Court may ultimately have to step in.
Chief legal officer Paul Grewal said he believes the dispute could reach the high court. While he cautioned that questions asked during oral argument do not reliably reveal how judges will rule, he noted that the final outcome may decide whether sports or event‑linked contracts fall entirely under CFTC authority or remain subject to parallel state gambling regimes.
Legal analysts say a clear circuit split between federal appeals courts would almost certainly accelerate Supreme Court review, forcing a national resolution of the boundary between federal financial regulation and state police powers.
Ninth Circuit presses similarities to casino bets
On April 16, during arguments in the Ninth Circuit, at least some members of the panel appeared skeptical that Kalshi’s contracts differ meaningfully from sportsbook wagers.
Judge Ryan Nelson pressed counsel to explain how a sports event contract on a prediction platform meaningfully differs from a bet placed at a Las Vegas casino such as Caesars, suggesting that the legal distinctions may be thinner than the company claims.
Those questions reflect a broader concern among some courts that new event‑based products are simply repackaged forms of gambling, despite their presentation as financial instruments.
Rapid market growth amid regulatory uncertainty
These legal battles are unfolding against the backdrop of a fast‑growing market. Combined monthly trading volume across event‑based platforms has surged from about $1.2 billion in early 2025 to more than $20 billion by January 2026.
That expansion has drawn sustained scrutiny from state regulators, who argue that consumer protections, age restrictions, and responsible gaming rules should apply to these products in the same way they apply to traditional betting.
At the same time, federal regulators have begun to outline a framework that treats event contracts as part of the derivatives ecosystem rather than as gambling products.
On March 12, the CFTC issued new guidance signaling a more supportive stance toward event contracts. The agency described them as innovative financial instruments falling within its exclusive jurisdiction, underscoring a growing gap between federal and state approaches.
State regulators escalate enforcement
Recent state actions highlight how aggressive the enforcement landscape has become:
- Ohio: On April 14, the Ohio Casino Control Commission moved to impose a $5 million fine on Kalshi, alleging the company operated without a state sports gaming license and accepted users under the minimum legal betting age of 21. This came after a federal judge in March refused to block the commission’s enforcement, bolstering the state’s position.
- Montana: On April 15, Kalshi filed a new lawsuit seeking to stop Montana officials from enforcing a cease‑and‑desist order that labels its products illegal gambling.
These cases stand in sharp contrast to the CFTC’s recent guidance, reinforcing a fragmented enforcement map that varies widely from one jurisdiction to another.
Direct impact on market access
The legal landscape is not just theoretical for platforms and traders. Court orders have had immediate operational effects.
When a Nevada judge issued a temporary restraining order in March, Kalshi was forced to cut off access to certain sports‑related markets for users located in the state. The incident underscored the speed with which a single ruling can reshape access to these products in a specific jurisdiction.
For traders, that means the ability to enter or exit positions may change overnight if a state court issues a new order or a regulator announces fresh enforcement.
Markets reacting to regulatory headlines
Research on related digital asset markets suggests that prices and trading volumes tend to move sharply in response to regulatory news.
Historically, announcements that point toward a clear, tailored legal framework for new financial instruments have coincided with broad market gains. By contrast, developments signaling bans or the application of strict existing gambling laws have produced some of the sharpest negative reactions.
Given the current mix of favorable and unfavorable rulings, analysts expect ongoing volatility directly tied to legal and regulatory headlines, as traders reprice the odds of long‑term viability and nationwide access.
Rules being written in real time
The ongoing court fights mean that the basic rules governing a rapidly expanding prediction market sector are being shaped case by case, rather than through a unified legislative overhaul.
For now, the industry operates in a splintered legal reality:
- some state and federal courts view event contracts as regulated derivatives under the Commodity Exchange Act;
- others treat them as gambling products that fall squarely within state control.
Until the Supreme Court or Congress provides a definitive answer, market participants face a prolonged period in which access, compliance obligations, and risk profiles may vary dramatically by state — and may change quickly in response to each new court decision.
