Is Kalshi legal in New Hampshire
No state keeps a larger share of each betting dollar than New Hampshire. No state loses more when that dollar leaves.
Short answer: Kalshi trades in New Hampshire and no publicly reported New Hampshire order restricts it. What makes this state different is the arithmetic. New Hampshire licensed exactly one sportsbook and takes 51 percent of its mobile revenue, the highest effective rate in the country. Every dollar that moves from that book to an untaxed exchange costs the state about fifty cents, and the company holding the monopoly is itself selling prediction markets in other states while excluding New Hampshire.

The arithmetic that makes this state unusual

Most states tax sportsbook revenue somewhere between 10 and 20 percent and license a dozen or more operators. New Hampshire did the opposite. In 2019 it auctioned a single exclusive licence covering both online and retail wagering, DraftKings won it, and the winning bid was a revenue share rather than a tax rate: 51 percent of mobile gross gaming revenue and 50 percent of retail. That arrangement has produced more than 172 million dollars for the state to date, and the Lottery Commission has extended it through the summer of 2028.

Now put a federally regulated exchange next to it. Kalshi holds no New Hampshire licence and pays the state nothing. When a New Hampshire resident moves a position from the licensed book to the exchange, the state does not lose a 15 percent tax slice the way Ohio or Illinois would. It loses roughly half of that revenue, because half of it was the states.

That is why New Hampshire has more riding on the outcome of this fight, per dollar wagered, than any other state in the country - and it is also why it has not obviously moved. New Hampshire Public Radio raised the question during March Madness in 2026 of whether prediction markets would deflate the states tournament revenue. The state has still filed nothing publicly.

Why the monopoly is hard to unwind

The contract contains its own trap. The 51 percent share is the price of exclusivity; reporting on the extension indicates the rate falls to roughly 21 percent if additional operators are licensed. Opening New Hampshire to competition would therefore cut the states take per dollar by well over half, and it would need the market to more than double in size just to break even.

So the state is financially locked into a single operator, that operator is locked into a rate no competitor would accept, and the competitive pressure is arriving from a direction neither of them can license or tax. A second sportsbook is the one competitor New Hampshire can keep out. An exchange is not.

The part that is genuinely strange

DraftKings did not sit out the prediction market wave. It launched its own event contract product to compete with Kalshi and Polymarket. But it did not launch it everywhere: certain states are excluded, and New Hampshire is one of them.

The reading that requires the fewest assumptions is that offering unlicensed event contracts in the one state where you hold an exclusive licence, and where you hand the government 51 cents on the dollar of your licensed revenue, is not a trade you want to explain to that government. Whatever the reason, the effect is that New Hampshire residents can trade sports event contracts on Kalshi, and cannot trade them with the company that holds the New Hampshire sports betting monopoly.

This page does not claim to know DraftKings reasoning, and the company has not been asked to state it here. What is on the record is the exclusion itself.

Where the national fight stands

CircuitCaseResult
ThirdNew JerseyRuled for Kalshi, April 2026
NinthNevadaRuled for the state, August 2026
SecondConnecticutKalshi appeal pending

States with a reported cease and desist or suit include Nevada, New Jersey, Maryland, Montana, Illinois, Ohio, Arizona, Tennessee, Massachusetts, New York and Connecticut. New Hampshire appears on none of them. Every dated action is in the prediction market change log, and the current map is in the Kalshi legality tracker.

Massachusetts sits next door and has acted. If the Second Circuit sides with Connecticut, the pressure on a state collecting 51 cents on the dollar becomes considerable.

What this means in practice

A New Hampshire resident today can open a Kalshi account and can also bet with DraftKings, the only licensed book in the state. Neither fact is a legal opinion, and the first could change on any business day if New Hampshire decides to act, as eleven other states have. Kalshi has geofenced or withdrawn markets in states after orders were issued, so present access is not a guarantee of continued access.

Frequently asked questions

Is Kalshi legal in New Hampshire?

Kalshi operates in New Hampshire and no publicly reported New Hampshire cease and desist order or lawsuit targets it as of 11 September 2026. New Hampshire is not a party to the Kalshi litigation running through the Second, Third and Ninth Circuits.

Who is allowed to take sports bets in New Hampshire?

Only DraftKings. New Hampshire awarded a single exclusive licence in 2019 covering both online and retail sports wagering, and the Lottery Commission has extended that arrangement through the summer of 2028.

How much does New Hampshire take from sports betting?

DraftKings pays 51 percent of mobile gross gaming revenue and 50 percent of retail gross gaming revenue to the New Hampshire Lottery. That has generated more than $172 million in state revenue to date.

Why does New Hampshire keep the monopoly?

Because competition would cost it money. The revenue share drops to roughly 21 percent if additional operators are added, so opening the market would cut the state take per dollar by more than half.
