New Hampshire Signs First U.S. State Bitcoin Reserve Law
Governor Kelly Ayotte signed HB 302 on May 6, 2025, making New Hampshire the first U.S. state to authorize its treasurer to hold Bitcoin as a reserve asset, after Arizona vetoed, Florida withdrew, and eight other states rejected similar bills.
HB 302 was signed on May 6, 2025. This piece covers the law's structure, what preceded it, and why it remains the benchmark for state-level Bitcoin reserve legislation.
The Granite State crossed the finish line nine other states could not reach, capping public fund allocation at 5% with a $500 billion market-cap floor that functions as a Bitcoin-only filter.
Key takeaways
- Governor Kelly Ayotte signed HB 302 on May 6, 2025, making New Hampshire the first U.S. state to enact a law authorizing Bitcoin as a treasury reserve asset.
- The law caps investment at 5% of total public funds and requires eligible digital assets to have a market cap exceeding $500 billion averaged over the prior calendar year. Only Bitcoin currently clears that bar.
- Arizona vetoed, Florida withdrew, and eight other states had already rejected similar legislation before New Hampshire's bill survived, making this the first functioning state-level proof of concept.
New Hampshire Governor Kelly Ayotte signed HB 302 on May 6, 2025, authorizing the state treasurer to invest up to 5% of total public funds in digital assets that meet the statutory eligibility threshold. It is the first law of its kind enacted anywhere in the United States, and it landed only after a full gauntlet of failures across ten other states.
The bill passed the House 192 to 179 and cleared the Senate committee 4 to 1. Primary sponsor Rep. Keith Ammon (R-Hillsborough) and Majority Leader Jason Osborne shepherded it through. The model legislation was drafted by the Satoshi Action Fund, whose CEO Dennis Porter has been the leading architect of state-level Bitcoin reserve strategy.
What the Law Actually Does
HB 302 does not mandate a purchase. It authorizes one. The state treasurer retains full discretion over timing, amount (subject to the 5% ceiling), and method of exposure. Custody can be direct state custody via a secure multisignature solution, a qualified custodian, or a U.S.-regulated exchange-traded product.
That last option means the treasurer could satisfy the law by buying into a product like BlackRock's IBIT without ever holding a private key.
The $500 billion trailing market-cap threshold is the law's most structurally significant feature. It is not Bitcoin by name, but Bitcoin is the only asset that has sustained that valuation on an annual average basis. The threshold insulates the bill from altcoin lobbying in committee and keeps the legal door technically open if another asset eventually crosses the bar on a sustained basis. That is a flag worth watching: the threshold is a Bitcoin moat today, but it is not a permanent one by statute.
The House margin (192 to 179) tells the real story about durability. This passed on party-line discipline. A shift in the governorship or a sustained bear market could put repeal on the table.
The authorization sitting unused through a full budget cycle would be the clearest signal that this is symbolic politics rather than a structural shift. That is the test.
Why the Gauntlet Matters
Arizona vetoed a similar bill, Florida withdrew before a floor vote, and eight other states, Oklahoma, South Dakota, Montana, North Dakota, Pennsylvania, and Wyoming among them, had already rejected similar legislation before New Hampshire signed. The legislative record across those states is the reason New Hampshire's signature carries weight. Every statehouse advocate now has a live example to point to: a functioning legal framework, enacted, with an effective date.
Dennis Porter framed it plainly: the first one is the hardest by far. Having a state that has already crossed the line increases political momentum for the rest.
The federal picture adds a parallel layer of pressure. Trump's March 2025 executive order established a federal Strategic Bitcoin Reserve funded only from law enforcement seizures, with no fresh taxpayer purchases authorized beyond budget-neutral strategies. New Hampshire's law goes further: it explicitly allows the treasurer to allocate new public funds. That distinction matters for anyone comparing the state and federal approaches.
Corporate treasuries are moving in the same direction. The CLARITY Act's commodity-pool provisions remain a live risk for entities trying to hold Bitcoin in fund structures, which makes state-level direct authorization frameworks more relevant, not less.
What to Watch
The first signal of real conviction will be an actual allocation announcement from the New Hampshire state treasurer, specifying the amount, the custody method, and the timing. Direct custody would signal genuine conviction; an ETP allocation would be a compliance-minimizing half-measure. Either outcome is informative.
The second signal is whether any other state enacts a law in 2025 or 2026 that cites HB 302 as precedent. If the model replicates, the dam is cracking. If New Hampshire remains the only state with an enacted law through the next legislative cycle, the thesis needs a harder look.

Frequently Asked Questions
No. HB 302 authorizes but does not mandate a purchase. The state treasurer retains full discretion over whether to invest, how much (up to the 5% cap), and which custody method to use. Whether any allocation has actually been deployed is a separate question from the law's passage.
Yes, in principle. The law's eligibility gate is a $500 billion market capitalization averaged over the prior calendar year, not Bitcoin by name. As of signing, only Bitcoin met that threshold. If another digital asset sustains that valuation on an annual average, it would qualify under the statute's current text.
Trump's executive order establishing the federal Strategic Bitcoin Reserve limits the reserve to Bitcoin already seized through law enforcement. No fresh taxpayer purchases are authorized beyond budget-neutral strategies. New Hampshire's law explicitly permits the treasurer to allocate new public funds, up to 5% of total holdings, for fresh Bitcoin acquisition.
