Arizona Attorney General Kristin K. Mayes filed a 20-count criminal information against prediction market operator Kalshi earlier this week, charging both of its operating entities with illegal betting, wagering, and election wagering under state law — the most direct state-level legal assault yet on a business model that Kalshi has spent years defending at the federal level.
The filing in Maricopa County Superior Court names KalshiEx LLC and Kalshi Trading LLC as defendants and details a methodical, low-dollar sting operation.
Investigators made bets as small as $1 across a wide range of Kalshi’s markets — sports wagers, political event contracts, and proposition bets — between December 2025 and March 2026, building a charge-by-charge record of transactions that Arizona prosecutors argue violated state gambling law on each occasion.

The 20 counts break into two categories. Sixteen counts of betting and wagering, Class 1 misdemeanors under A.R.S. § 13-3305, cover a broad sweep of markets: a $30 wager on the Washington Commanders versus the New York Giants, $1 bets on college basketball games, a $5 spread bet on the Oklahoma City Thunder, a $1 bet on whether the SAVE America Act would become law, and $20 parlays.
Four counts of election wagering, Class 2 misdemeanors under A.R.S. § 16-1015, cover specific political contests: a $2 wager on whether JD Vance would win the 2028 presidential election, a $2 bet on whether a Republican would win the 2026 Arizona governor’s race, a $1 bet on whether Andy Biggs would win the 2026 Arizona Republican gubernatorial primary, and a $1 bet on whether a Democrat would win the 2026 Arizona Secretary of State race.
Investigators also placed a $1 proposition bet on whether Elon Musk would attend the Super Bowl between the Seattle Seahawks and the New England Patriots on February 8, 2026 — a market that blurs the line between celebrity speculation and a political figure who served as a senior administration official.
The filing also alleged that neither entity was registered with the Arizona Corporation Commission as a foreign limited liability company, as required under A.R.S. § 29-3902(B), adding a corporate compliance violation onto the underlying gambling charges.

Kalshi won a landmark federal court ruling in 2024 allowing it to offer political event contracts under Commodity Futures Trading Commission oversight, having argued successfully that its products are financial instruments — not wagers — and fall under federal jurisdiction. Arizona’s charges directly test that argument at the state level, raising the question of whether a federal regulatory classification can preempt state criminal law.

The prediction markets industry, which has grown rapidly since Kalshi’s federal win, is watching the case closely. If Arizona’s theory holds up — that accepting bets on political outcomes violates state election wagering statutes regardless of how the federal government classifies the product — every state with similar laws could move against national prediction market platforms.
Rivals including Polymarket and PredictIt have also expanded their US footprints in the wake of the 2024 ruling.

Kalshi has not publicly commented on the charges. A summons, not an arrest warrant, was requested in the filing.
