Can States File Criminal Charges Against Prediction Markets?

Yes, states can — and now have — filed criminal charges against prediction market companies. In March 2026, Arizona's attorney general filed the first-ever criminal charges against Kalshi, alleging the CFTC-regulated prediction market exchange was operating an illegal gambling business and running unlicensed election wagering in the state.

The Arizona–Kalshi Criminal Case

On March 17, 2026, Arizona prosecutors charged Kalshi with criminal misdemeanors, accusing the company of:

• Operating an unlicensed online gambling operation in Arizona
• Offering sports betting without approval from Arizona's gaming commission
• Allowing election wagering, which is illegal under state law

While Kalshi's executives were not personally named as defendants, the charges carry potential consequences including asset forfeiture and even jail time under Arizona statute. Kalshi called the charges "seriously flawed" and "meritless."

This was not the first legal action against Kalshi — more than 20 civil lawsuits from various states were already pending — but it marked the first time a state escalated to criminal prosecution.

Why States Are Taking Action

The core dispute is a jurisdictional conflict between federal and state authority:

• Federal argument: Prediction markets are event contracts regulated by the CFTC under the Commodity Exchange Act. The CFTC has approved companies like Kalshi as Designated Contract Markets (DCMs), and federal regulation preempts state gambling laws.
• State argument: Prediction markets look, feel, and function like gambling — particularly when they involve sports outcomes and elections. States have long-established regulatory frameworks for gambling, and a federal commodity designation does not automatically override state gambling statutes.

From the state perspective, a CFTC-regulated prediction market offering sports-outcome contracts to residents without a state gaming license is no different from an unlicensed sportsbook.

The Federal Response

The Trump administration has publicly sided with prediction market companies in this dispute. CFTC Chairman Michael Selig called Arizona's criminal charges "a jurisdictional dispute and entirely inappropriate as a criminal prosecution," stating the agency was "watching closely and evaluating its options."

The CFTC under the current administration has taken an expansive view of prediction market legality, allowing the industry to grow rapidly since easing regulatory restrictions on Polymarket in September 2025.

What This Means for iGaming Operators

For operators evaluating prediction market integration, the Arizona case highlights several critical considerations:

Regulatory Uncertainty Is Real

The prediction market space exists in a genuine legal gray zone. A CFTC designation does not guarantee immunity from state prosecution, and multiple states are actively challenging the industry.

State-by-State Compliance Matters

Even if federal regulators approve a prediction market product, operators must evaluate state-level gambling laws in every jurisdiction where they plan to offer it. What is legal in one state may trigger criminal liability in another.

The Precedent Is Set

Arizona's criminal charges open the door for other states to pursue similar enforcement actions. States with strict gambling regulations — or those that generate significant revenue from licensed sportsbooks — have strong incentives to challenge unregulated prediction market operators.

Sports Integrity Frameworks Are Essential

Part of the state pushback stems from concerns about sports integrity. Operators integrating prediction market products need robust integrity agreements — as demonstrated by the MLB-CFTC memo of understanding signed alongside Polymarket's partnership deal.

Frequently Asked Questions

Has any state filed criminal charges against a prediction market?

Yes. Arizona filed the first criminal charges against Kalshi in March 2026, alleging it operated an unlicensed gambling business in the state.

Can the CFTC override state gambling laws?

This is the central legal question. The CFTC argues federal preemption applies, while states contend their gambling statutes remain enforceable. Courts have not definitively resolved the issue.

What are the penalties for operating an unlicensed prediction market in a state?

Penalties vary by state. In Arizona, the criminal misdemeanor charges against Kalshi could include fines and asset forfeiture. Other states may impose different penalties under their gambling codes.

Are prediction markets legal in the United States?

At the federal level, the CFTC has approved several prediction market exchanges as regulated entities. However, legality varies significantly by state, and multiple states are actively challenging whether federal approval overrides state gambling laws.

Should iGaming operators wait before launching prediction market products?

Operators should conduct thorough jurisdiction-by-jurisdiction legal analysis before offering prediction market products. The regulatory landscape is actively evolving, and state enforcement actions like Arizona's demonstrate real legal risk.
