Arizona’s Attorney General Kris Mayes has filed a 20‑count criminal complaint against KalshiEx LLC and Kalshi Trading LLC, the companies behind the online prediction market platform Kalshi, alleging that the business has been operating an illegal gambling enterprise within the state. The charges, filed in Maricopa County Superior Court, represent the first state criminal prosecution of its kind against a prediction markets operator.
Mayes’ office argues that Kalshi’s model, which allows users to place real‑money wagers on outcomes like sports contests, elections and even political propositions, “violates Arizona law” because it constitutes unlicensed gambling and includes wagers specifically prohibited by state statutes.
Detailed Allegations: Betting and Election Wagering Counts
The criminal information in the official complaint lays out multiple counts alleging that Kalshi accepted wagers on a wide range of events, classifying the conduct as illegal under Arizona statutes prohibiting unlicensed gambling and election betting.
The charges include:
- Counts for betting and wagering: Several counts allege Kalshi accepted, recorded or registered bets on sports contests and contingent future events, activities defined as gambling under state law.
- Counts for election wagering: Four counts specifically relate to bets involving political outcomes, including wagers on the 2028 U.S. presidential election, the 2026 Arizona gubernatorial race, the 2026 Republican primary and the Secretary of State race, all explicitly banned under Arizona law.
- Examples of alleged wagers include bets taken as early as December 2025 through February 2026 on sporting events involving NFL teams, college basketball games and other contingent events.
The complaint uses specific transactions as evidence, alleging that Kalshi accepted certain bets on sports outcomes and proposition wagers without holding the necessary licences to conduct gambling activities in Arizona.
Attorney General Mayes emphasised in the press release:
Kalshi may brand itself as a ‘prediction market’, but what it’s actually doing is running an illegal gambling operation and taking bets on Arizona elections, both of which violate Arizona law. No company gets to decide for itself which laws to follow.
Pushback and Federal vs State Regulatory Tension
Kalshi has responded to the charges by contending the allegations are unfounded, arguing its contracts are regulated under the Commodity Futures Trading Commission (CFTC) as financial event contracts rather than gambling bets. The company claims that arguing state gambling law applies to its federally regulated derivatives is legally incorrect.
This clash reflects a broader jurisdictional dispute between states and federal regulators over how prediction markets should be regulated. Kalshi and similar platforms have previously faced civil actions from several states contending services constitute unlicensed wagering, while the Commodity Futures Trading Commission asserts its authority to regulate event contracts under the Commodity Exchange Act.
Legal and Industry Context: Prediction Markets at Regulatory Crossroads
Arizona’s criminal action escalates a series of legal challenges prediction market platforms have faced nationwide:
- Several states, including Massachusetts, Nevada and Michigan, have pursued civil enforcement actions or injunctions against Kalshi for allegedly offering unlicensed betting markets.
- A federal judge in Nevada previously ruled that Kalshi must comply with state gaming rules when operating certain wagering markets, pushing back on the argument that federal law preempts state gambling jurisdiction.
Arizona’s approach differs from prior actions by moving beyond civil enforcement, charging Kalshi criminally and framing its operations as a state law violation, not merely a regulatory compliance issue.
These developments echo broader debates over prediction markets’ place in U.S. gambling law, including legislative initiatives aimed at clarifying the legal status of such platforms. States like Minnesota have proposed bans on prediction markets alongside sweepstakes and other non‑traditional gambling products, reflecting heightened regulatory concern.
What This Means for the Prediction Market Sector
Arizona’s criminal prosecution introduces a new legal risk landscape for prediction market operators:
- Operators may face criminal liability in states that deem their platforms to be unlicensed gambling businesses.
- Platforms will likely see heightened regulatory scrutiny at both state and federal levels as jurisdictions push back against event betting models deemed unsafe or outside their regulatory purview.
- The case could prompt further examination of where prediction markets intersect with prohibited election wagering laws, as seen in multiple counts in the Arizona complaint.
The industry debate also extends beyond state courts, intersecting with policy questions about federal oversight versus state authority, especially as regulators grapple with emerging wagering formats that blur lines between gambling, derivatives trading and entertainment products.
