The mNAV Compression: What the Market Now Pays for a Bitcoin Balance Sheet

For three years, the pitch behind every bitcoin treasury company was the same: the market will pay more than a dollar for a dollar of bitcoin on a corporate balance sheet. For most of 2024 and early 2025 that was true, sometimes wildly so. It is no longer reliably true, and the gap between the companies the market still rewards and the ones it now discounts has become the defining divide of the sector.

What mNAV measures — and which mNAV you are looking at

mNAV is the multiple of a company's valuation to the value of the bitcoin it holds. The definitions matter more than they look. Bitcoin Treasuries' glossary defines the strict version as enterprise value — market cap of all share classes, plus debt and perpetual preferred, minus cash — divided by BTC held times spot price. A simpler basic variant divides market cap alone by bitcoin NAV; that is the variant our tracker publishes, with each company's debt broken out beside it. The same firm can sit above parity on one variant and below it on another — in November 2025, NYDIG's global head of research Greg Cipolaro called headline mNAV "woefully deficient" precisely because it tends to treat convertible notes as guaranteed future equity. Any serious read of the sector starts by asking which multiple is being quoted.

The compression, dated

The mania peaked in May 2025, when Nakamoto floated at roughly 23× mNAV, a sector record. The warnings began almost immediately: in late June 2025, VC firm Breed published a report arguing few treasury companies would survive a "death spiral" that starts exactly here — a falling bitcoin price compresses mNAV toward 1×, which shuts the equity-and-convert financing window the whole model depends on.

• August 22, 2025 — roughly 1 in 3 of 156 listed crypto treasury firms traded below the value of their coins, per Capriole Investments data reported by DL News.
• October 2025 — about a quarter of public BTC treasury companies sat below 1.0×, against historical premiums of 2–5×; Strategy touched a 19-month low and Metaplanet fell from a 237% premium toward parity (Protos).
• January 2, 2026 — at least 37 of the top 100 traded below NAV: DL News put Strategy at a 17% discount, Twenty One Capital at 17%, H100 at 32%, Vanadi Coffee at 61%. Days later, Bitcoin Treasuries printed the tail: Nakamoto 0.47×, Cango 0.40×, CIMG 0.26×.
• August 31, 2026 — partial recovery at the top on the enterprise-value measure: mnav.comshowed Strategy at 1.06× (52-week range 0.96–1.43×) and Metaplanet at 1.08×. The variant gap was on full display the same day — our tracker's basicmNAV for Strategy stood at 0.76×, matching Bitcoin Treasuries' basic figure — while Twenty One Capital traded around 0.7× enterprise mNAV after a $413.5M Q2 loss.

Why it happened

Four causes recur across the analyst record. Dilution fatigue: as CoinDesk's later reporting traced, analyst James Check argued as early as mid-2025 that most firms could not sustain accumulation aggressive enough to justify premium valuations — issuing shares at a premium to buy BTC only works while the premium lasts. Saturation: ParaFi's Kevin Li, via CoinDesk, pointed to a crowded field of near-identical crypto equities chasing the same allocators. Index risk: MSCI's consultation on excluding companies whose digital assets exceed half their balance sheet hung over the sector through late 2025, with analysts warning of $10–15B in forced selling before MSCI decided against exclusion in January 2026. And the financing flywheel in reverse: once mNAV nears 1×, accretive issuance stops, which is the Breed death-spiral mechanism doing its work.

What the discount did to behavior

Compression stopped being a chart and started being corporate strategy. Metaplanet filed no purchase notices for roughly three months after its mNAV slipped below 1.0 in late 2025, then arranged a $500M credit line supporting buybacks (Bitbo). Sequans sold 970 BTC in November 2025 to cut debt, redeemed its convertibles by May 2026, and ended its treasury experiment (Coinpedia). Twenty One Capital's new CEO put it plainly, per The Block: a persistent gap "could be viewed as a misallocation of capital." The wind-downs, pauses, buybacks and pivots all follow the same arithmetic: below 1.0×, a dollar of buyback retires more than a dollar of bitcoin exposure per share, so treasurers acting on BTC-per-share logic shift from accumulation to repurchase.

What a discount is not

A sub-1× multiple is not automatically a bargain. The deep-discount names tend to carry the reasons for their discounts with them — governance structures that block a liquidation, debt senior to the bitcoin, operating burn, or simple illiquidity. The "mNAV trap" argument — that 70% discounts are structural warnings, not mispricings — is the strongest single corrective to reading our tracker's discount column as a shopping list. It is a description of what the market will pay for a bitcoin balance sheet, nothing more.

What to watch from here

Three things decide whether the recovery at the top spreads down the roster: whether the largest holders keep mNAV above the financing threshold, whether the 2027–2029 convertible maturities get refinanced without forced BTC sales — mapped in our companion report, The Maturity Wall — and whether the discount tail keeps converting into buybacks, mergers and exits. All three are trackable, and we track them.
