Are Prediction Markets Gambling? Arizona Just Filed Criminal Charges to Find Out
Arizona just filed criminal charges against Kalshi. Here's what the case means for prediction markets, state law, the CFTC, and users.
Posted March 18, 2026 | Category: Regulation | ~9 min read
Arizona made history on March 17, 2026 — and not in a good way for prediction markets. The state's Attorney General became the first in the country to file criminal charges against Kalshi, the federally regulated prediction market platform, accusing it of running an illegal gambling operation and accepting bets on Arizona elections.
Twenty counts. Criminal court. First-ever charges against the industry.
The move sent shockwaves through the prediction market space and crystallized the central legal question that has been building for months: Are prediction markets gambling, or are they something fundamentally different? The answer to that question — being debated simultaneously in state courthouses, federal courts, Congress, and the CFTC — could reshape an industry that has exploded into mainstream finance.
Here's everything you need to know about what happened, what it means, and whether your Kalshi account is at risk.
What Actually Happened: The 20-Count Filing
On March 17, Arizona Attorney General Kris Mayes filed a 20-count criminal information against KalshiEx LLC and Kalshi Trading LLC in Maricopa County court. The charges are misdemeanors — not felonies — but the precedent is massive.
The charges allege Kalshi violated two distinct Arizona laws:
-
Operating an unlicensed wagering business — Arizona law requires a license to accept wagers from state residents. Kalshi, which holds federal CFTC authorization, does not hold an Arizona gambling license.
-
Election wagering — Arizona explicitly bans betting on elections. The filing includes four counts of election wagering for accepting bets on the 2028 presidential race, the 2026 Arizona gubernatorial race, the 2026 Arizona Republican gubernatorial primary, and the 2026 Arizona Secretary of State race.
The remaining counts cover bets Kalshi accepted on professional and college sporting events and individual player performance — all things Arizona classifies as gambling under state law.
"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," Attorney General Mayes said in her office's official press release. "No company gets to decide for itself which laws to follow."
Importantly, the charges are misdemeanors — not felonies. But misdemeanor convictions in Arizona can carry asset forfeiture and, in theory, the possibility of jail time, according to reporting from NPR. No Kalshi executives were personally named in the filing.

Why Now? The Timing Is Not a Coincidence
The charges came just five days after Kalshi filed a preemptive lawsuit against the State of Arizona in federal court on March 12 — a move Mayes called an attempt "to avoid accountability under Arizona law." Kalshi had filed similar preemptive suits against Utah and Iowa.
Kalshi's response was swift and direct: "These state-court charges are seriously flawed. It's gamesmanship. Four days after Kalshi filed suit in federal court, these charges were filed to circumvent federal court and short-circuit the normal judicial process."
Adding fuel to the fire: a federal judge — U.S. District Judge Michael Liburdi, a Trump appointee — denied Kalshi's request for a temporary restraining order and ordered Kalshi to demonstrate why its case should remain in federal court given the new state criminal charges.
That's not a small development. Kalshi's core legal strategy has been to "win the race to the courthouse" by getting federal injunctions before states can act. That strategy has worked in New Jersey and Tennessee. It failed this week in Arizona.

The Core Legal Question: Prediction Market or Gambling Operation?
At the heart of this battle is a genuinely unresolved legal question — one that different courts have answered differently.
Kalshi's argument: Prediction markets are federally regulated financial instruments. They issue event contracts under CFTC oversight, which grants the federal agency exclusive jurisdiction. Individual states cannot regulate what federal law has already covered. The company draws a specific distinction: customers trade contracts against each other (like a stock exchange), rather than betting against "the house" like a casino. That peer-to-peer swap structure, Kalshi argues, puts it outside traditional gambling definitions.
Arizona's argument: Call it what you want — if it looks like gambling, walks like gambling, and accepts unlicensed wagers from Arizona residents on sports and elections, it's gambling under Arizona law. The state explicitly prohibits election betting, and no federal license overrides that.
The CFTC's position: The Trump administration's CFTC has firmly sided with Kalshi and Polymarket, filing amicus briefs in multiple cases asserting exclusive federal jurisdiction over event contracts. CFTC Chairman Michael Selig called the Arizona criminal filing "entirely inappropriate as a criminal prosecution" in a statement on X (formerly Twitter). The agency is "watching this closely and evaluating its options."
The practical reality is that courts have split. Federal judges in New Jersey and Tennessee issued rulings in favor of Kalshi. Federal and state judges in Nevada and Massachusetts issued early rulings favoring states seeking to ban the platforms. Nevada's case was remanded to state court. At least a dozen states have taken some form of legal action against Kalshi.

The Political Dimension: Trump, Trump Jr., and the Industry
The prediction market battle isn't just a legal fight — it's become politically charged in ways that matter for understanding how it plays out.
Donald Trump Jr. is a strategic advisor for Kalshi. President Trump's social media platform, Truth Social, is launching Truth Predict, its own cryptocurrency-based prediction market. The Trump administration has thrown its support behind the industry, further amplifying the state-versus-federal fight for regulatory control.
"President Trump's administration has thrown its support behind the multibillion-dollar prediction market industry," according to the AP's reporting, "further amplifying a state-versus-federal fight for regulatory control. The outcome could have sweeping implications for how sports betting — which makes up roughly 90% of Kalshi's trading volume — is regulated in the U.S."
That last figure — 90% sports betting — is worth pausing on. Kalshi's biggest volume categories are sports event contracts. The same markets states classify as sports betting under state gaming law.
Meanwhile, Congress is in play too. A bipartisan House bill has been introduced that would prohibit event contracts on sports unless a state specifically permits them, and would ban prediction market contracts on elections and government actions entirely, according to CNBC.

Where Does Polymarket Fit In?
Kalshi isn't alone. Polymarket — which recently acquired QCX LLC, a CFTC-licensed exchange, to re-enter the US market — has also faced state regulatory pushback in Nevada and Massachusetts, where early rulings went against the platform.
The difference is that Polymarket operates primarily on blockchain infrastructure with USDC settlements, which creates a slightly different legal profile. But the state-versus-federal jurisdiction question applies equally: if states can regulate Kalshi, they can regulate Polymarket.
For now, Polymarket continues to operate for US users via its QCX LLC structure, with strong market activity. As of today's market data, Polymarket's Fed Decision market alone has logged $49.26 million in 24-hour volume — underscoring how much money is flowing through these platforms regardless of the legal uncertainty.

What This Means for Prediction Market Users
If you're currently trading on Kalshi: The criminal charges are misdemeanors against the company entities (KalshiEx LLC and Kalshi Trading LLC), not against individual users. There is no indication that Arizona is targeting traders who placed bets through the platform.
Is Kalshi still operating? Yes, as of this writing. A criminal misdemeanor filing does not automatically shut down operations. The litigation will play out over months or years.
Could this affect Coinbase, Robinhood, and other Kalshi-powered platforms? Potentially. Coinbase Predict and Robinhood both operate prediction markets powered by Kalshi's infrastructure. Robinhood launched in 49 US states in early 2026 (Maryland is excluded from all event contracts). Coinbase launched in all 50 states — the Nevada Gaming Control Board civil enforcement action (filed February 2, 2026) was seeking a TRO, but that TRO was DENIED February 5, 2026; Coinbase's initial rollout was announced January 28, 2026. If a state successfully bans Kalshi, its distribution partners would likely have to comply.
What about states where you can't currently trade? Coinbase's prediction markets are available to US residents in all 50 states — the Nevada Gaming Control Board's motion for a TRO (filed February 2, 2026) was denied February 5, 2026. Check Coinbase's help documentation for current availability. The legal landscape could change that.

The Khamenei Fallout: Trust Was Already Fragile
Arizona's charges land on top of another controversy that has battered Kalshi's reputation with users: the Khamenei payout dispute.
In February 2026, Iran's Supreme Leader died on February 28. Kalshi had been running a market on whether Iran's supreme leader would leave office before March 1. After the death, Kalshi invoked a clause specifying that removal by death would result in no payout — the contract would not settle as a win for "Yes" bettors.
Traders filed suit, claiming the clause was not properly disclosed. Kalshi's CEO defended the policy and said the company reimbursed all fees from the market. But the damage to user trust was real: the company had taken a legal-but-surprising interpretation of contract terms at the moment of a major payout.
The timing of that controversy, combined with the Arizona criminal charges, has made March 2026 a particularly rough stretch for Kalshi's reputation — even as the company continues to operate normally.

What Happens Next
Several fronts are active simultaneously:
-
Arizona criminal case: Will proceed in Maricopa County court unless resolved via federal jurisdiction argument or settlement. Kalshi is fighting to get it moved to federal court.
-
Other state actions: At least a dozen states have taken some form of legal action against Kalshi. Utah's Republican governor has pledged to sign a bill that could undercut Kalshi's business in the state.
-
Congressional action: The bipartisan House bill targeting sports and election event contracts could reshape the entire space if it passes.
-
CFTC rulemaking: The CFTC under Chairman Selig has been asserting federal jurisdiction aggressively. The agency may intervene more directly in the Arizona case.
-
Federal courts: The ultimate question — whether CFTC regulation preempts state gambling law for event contracts — has not reached an appellate court. When it does, that ruling will likely settle the national question.
The NCAA tournament, which tips off this week, adds urgency. Kalshi announced a $1 billion perfect bracket challenge this week. Arizona and other states have flagged that timing as significant context.
FAQ: Prediction Markets and the Law
Are prediction markets legal in the US? At the federal level, yes — Kalshi holds a CFTC Designated Contract Market (DCM) license and is federally regulated. Polymarket operates through its QCX LLC subsidiary, also CFTC-licensed. The fight is about whether federal regulation preempts state gambling laws. That question is currently unresolved.
Can states shut down Kalshi? Courts have split on this. Some federal judges have ruled states cannot regulate federally licensed exchanges. Others have let state actions proceed. Arizona's criminal case will add another data point.
Is betting on elections illegal everywhere? No — most states don't have explicit election betting bans. Arizona is unusual in that it explicitly prohibits betting on elections. The federal CFTC has generally allowed political event contracts at the federal level.
What are my risks as a Kalshi user? Individual users are not the target of state enforcement actions. The risk is platform disruption: if Kalshi faces court orders to restrict operations in certain states, access could be affected. Your funds are held in segregated accounts and regulated under CFTC rules.
Does this affect Polymarket users? Polymarket faces similar state-level pressure in Nevada and Massachusetts. US users can currently access Polymarket via its QCX LLC structure. The same state-vs-federal dynamic applies.
What about Robinhood and Coinbase prediction markets? Both platforms power their prediction markets through Kalshi's infrastructure. Any major legal action against Kalshi that restricts operations could affect access through these platforms. Neither Robinhood nor Coinbase has commented on the Arizona charges specifically.
The Bottom Line
Prediction markets have gone from niche academic curiosity to mainstream financial product in two years. That growth has outpaced the legal frameworks designed to govern them, creating the exact conflict playing out in Arizona courtrooms.
The question isn't whether Kalshi's event contracts are interesting or useful — they clearly are, with hundreds of millions in trading volume proving market demand. The question is whether a federally licensed derivatives exchange can operate in all 50 states without state-level gambling licenses, and whether CFTC jurisdiction preempts state police power.
That question doesn't have a final answer yet. What Arizona did this week is force the issue in a new, more aggressive way — criminal charges instead of civil ones, state court instead of federal.
The outcome will shape the entire prediction market industry for years. And it's playing out right now.
