Q: Are prediction markets legal? Is Kalshi gambling?

Prediction markets like Kalshi and Polymarket US are regulated by the CFTC as exchanges, which is why they operate across most of the US. But many states argue sports contracts are illegal unlicensed gambling. As of October 2026, the Third Circuit sided with Kalshi, while the Ninth and Sixth Circuits sided with the states, and New Jersey has asked the Supreme Court to settle it. What you can trade depends on your state, and the apps check your location.

Short answer

They're federally regulated exchanges, not state-licensed sportsbooks.Many states say sports contracts are gambling and are fighting them in court.Appeals courts are split 2 to 1 for the states, as of October 2026.Whatever the law calls it, treat it like a bet.

Short answer: they're federally regulated, and they're also being fought by a lot of states. Both things are true at once, and that's why the rules feel confusing.

Why they're allowed at all

Kalshi and Polymarket US run exchanges regulated by the CFTC, the federal agency that oversees futures markets. Under that system, a sports contract is treated like a financial product, not a bet. That's why these apps call it a trade and why Kalshi lets people 18 and older use it, while most state sportsbooks require you to be 21.

Why states push back

Most states license and tax sportsbooks. Their view is simple: if you pay money and win money on a game, that's sports betting, no matter what the app calls it. More than a dozen states have taken legal action against Kalshi over sports contracts.

What this means for you

▸What you can trade depends on where you are. The apps check your location and only show what's available.

▸A contract you can trade today could be pulled in your state later.

▸Your money sits with a regulated exchange either way, but read each app's terms on what happens if a market closes in your state.

So is it gambling?

Legally, the courts haven't finished deciding. Practically, here's my honest take. You're putting money on the outcome of a game. Size it like a bet, track it like a bet and never chase a loss because the screen looks like a stock app.
