Approximately 1 out of every 3 of the nearly 156 listed crypto treasury companies are currently worth less than the Bitcoin they hold on their balance sheets: they are trading below their mNAV. The mNAV (market net asset value, the ratio between market capitalization and the market value of its BTC reserves) is the metric that explains everything, and the data is compiled by Capriole Investments via DL News. It describes a regime shift: for nearly three years, the "MicroStrategy" model consisted of issuing shares above the value of their reserves to buy more Bitcoin and increase Bitcoin-per-share. That premium—what the market paid over the BTC in the vault—was the product. And the premium is dead. When a treasury trades below 1x its mNAV, the same engine that drove its growth begins to spin in reverse: every new share issued to buy BTC dilutes the Bitcoin attributable to each shareholder instead of increasing it. This article deconstructs those mechanics with numbers, explains why the avalanche of imitators compressed the premium until it broke, and answers the question readers are truly asking—"is a Bitcoin treasury company safe?"—using the mathematics of the discount rather than headlines.
What is mNAV and why was the premium the real product?
A Bitcoin treasury company is a listed wrapper around a pile of BTC: you buy the stock and indirectly own a fraction of its reserves, and the mNAV measures how much that fraction costs compared to buying Bitcoin directly.
The mNAV (market net asset value) multiple addresses this. It is the company's market capitalization divided by the market value of its Bitcoin net of debt. An mNAV of 2x means the market pays two dollars for every dollar of BTC the company holds. 1x means parity. And below 1x, the stock is worth less than the Bitcoin backing it: a discount.
During the first three quarters of 2025 (Q1-Q3 2025), according to reports from DL News and Capriole, treasuries enjoyed substantial premiums. Strategy—formerly MicroStrategy—reached trading levels around 3.3-3.4x at its peak in November 2024, according to estimates cited by DL News and Coindesk. That premium was not an irrational market whim: it was the fuel for the model. As long as the stock trades above the underlying BTC, the company can issue new shares, sell them at a high price, use the proceeds to buy Bitcoin, and end up with more Bitcoin-per-share than before. It is the carry trade (borrowing or issuing cheaply to invest in something with a higher yield) that turned a software company into the largest corporate holder of BTC on the planet, with over 840,000 coins (843,738 declared on May 26, 2026).
The key that almost no one explains: the shareholder wasn't buying Bitcoin, but rather a machine for increasing Bitcoin-per-share that only works if the market continues to pay the premium. The premium was the product; BTC was the raw material.
Why does the model break below 1x?
Imagine a treasury with 100 BTC and 100 shares outstanding. The Bitcoin-per-share is 1.0.
Premium scenario (mNAV 2x). The market pays double the underlying BTC. The company issues 50 new shares and, since each share is worth two market Bitcoins, it raises the equivalent of 100 BTC. It buys 100 BTC. Now it has 200 BTC spread across 150 shares: 1.33 Bitcoin-per-share. The shareholder who did nothing is 33% richer in BTC. This is how it worked for two years.
Discount scenario (mNAV 0.80x). Same company, 100 BTC and 100 shares, but now the market pays only 0.8 Bitcoins for each share. The company issues 50 new shares and raises the equivalent of 40 BTC. It buys 40 BTC. Now it has 140 BTC spread across 150 shares: 0.93 Bitcoin-per-share. The existing shareholder has just lost Bitcoin without anyone touching the BTC balance. The issuance, which previously created value, now destroys it.
| Same issuance: 50 new shares | With premium (mNAV 2x) | With discount (mNAV 0.80x) |
|---|---|---|
| BTC raised and purchased | 100 BTC | 40 BTC |
| Resulting BTC-per-share | 1.33 (+33%) | 0.93 (−7%) |
The engine is the same—issue shares, buy Bitcoin—but the sign flips as soon as the mNAV crosses below 1x. Above parity, issuing is accretive (it raises BTC-per-share). Below, it is dilutive (it lowers it). In practice, there is no neutral middle ground: fees and placement discounts push the real threshold slightly above 1x.
Hence the nickname circulating in the industry: the "spiral" or spiral of doom. If the stock falls to a discount, the company loses its growth tool; without growth, the market withdraws more of the premium and the discount deepens. And if it also has dividends or debt to pay, it may be forced to sell the very BTC that was supposed to be untouchable.
How widespread is the discount right now?
It is not an isolated case. According to Capriole Investments via DL News, about 1 in 3 of the approximately 156 listed crypto treasury companies were at an mNAV discount in mid-June 2026. Other counts show similar figures: some pointed to 1 in 4 among purely Bitcoin firms, and another cited by DL News raised the proportion to 40% when including Ether and Solana. The exact number depends on which firms are included in the sample and what debt is subtracted, but the direction is unmistakable: the discount is no longer the exception.
Most revealing is who is on the list. It's not just small projects without a business. Strategy itself and Twenty One Capital—a Bitcoin treasury backed by Tether and SoftBank, launched in 2025 and one of the five largest in the sector—have traded at a discount: Twenty One Capital was around 17% below its NAV according to data cited by DL News (Apr-2026).
| Metric | 2024 Peak | June 2026 |
|---|---|---|
| Strategy (MSTR) mNAV | ~3.3-3.4x | ~0.82x |
| Premium/discount over BTC | approx. +230-240% | −18 to −21% |
| Listed crypto treasuries (Capriole sample) | — | ~156 |
| Proportion at discount (mNAV < 1x) | marginal | ~1 in 3 |
| Twenty One Capital discount | — | ~17% |
Figures as of June 23, 2026; mNAV is volatile and moves every session. The drop from ~3.3x to 0.82x in Strategy is the clearest snapshot of the regime change: same company, same model, same founder, and a market that went from paying over three dollars for every dollar of BTC in the vault to charging a near double-digit discount.
Why has the premium compressed?
Two forces, both direct consequences of the model's own success.
The first is competition. Strategy's trick was replicable, and it was replicated. Standard Chartered already warned—in a note dated September 15, 2025—that the original formula had generated roughly 89 imitators, joined by waves of Ether and Solana treasuries. When there is only one wrapper around Bitcoin, the market pays for rarity. When there are 156, it pays for what the contents are worth and little more. The premium is, in part, a price for the scarcity of the vehicle, and that scarcity vanished.
The second is the spot ETF. Since low-fee Bitcoin exchange-traded funds have existed, investors seeking clean exposure to BTC no longer need a corporate wrapper with debt, preferred dividends, and management risk on top. If you can buy Bitcoin almost directly through an ETF, why pay a premium for a leveraged and opaque version of the same thing? The ETF drained exactly the marginal demand that sustained the premium. To understand this competing vehicle, it is worth reviewing what a spot crypto ETF is and how it differs from holding the coin.
The result is a pincer movement: from above, ETFs offer cheaper exposure; from the sides, dozens of imitators dilute rarity; and the premium, caught between both, compresses until it crosses 1x. What killed the premium wasn't a Bitcoin crash: it was the maturation of the very market the model helped create.
What signals separate survivors from those entering the spiral?
A company trading below 1x is not doomed by that fact alone. What determines if the discount is a passing inconvenience or the start of a spiral is the balance sheet structure. These are the signals industry analysts watch.
- Mandatory payment obligations. Preferred dividends and debt coupons must be paid in cash, come rain or shine. A company without these burdens can simply stop issuing shares and wait for the premium to return. One with a large preferred dividend has a clock ticking: if fresh cash doesn't come in, the temptation—or necessity—to sell BTC to cover the payment grows every quarter.
- Convertible debt maturities. Convertibles were issued on the assumption that the stock would rise and they would convert into equity. With the stock at a discount, that conversion becomes unlikely, and the debt must be refinanced or repaid in cash, just as the tool for raising cheap capital has broken.
- Liquidity and operating business. A treasury that also generates revenue from a real business has a cushion. Those that are pure BTC vaults, with no income, depend 100% on capital markets to survive.
- The perverse incentive of the value trap. Capriole points out: below 1x, repurchasing own shares is accretive (you buy cheap BTC via your own shares), which pushes some firms to sell Bitcoin to fund the buyback. It's the trap: the rational path for the short-term shareholder is to dismantle the BTC pile.
The practical distinction is stark: with a premium, issuing shares is the optimal move; with a discount, repurchasing shares (by selling BTC) can be. The model has no "wait without doing harm" mode when mandatory payments are due.
What signal did Strategy's first Bitcoin sale since 2022 send?
The most discussed episode featured Strategy itself. According to SEC filings reported by Coindesk and Cryptobriefing, the company sold 32 BTC for approximately $2.5 million between May 26 and 31, 2026—its first Bitcoin sale since 2022—at an average price of around $77,135 per coin. The stated goal: to cover the dividend on its STRC preferred shares.
In absolute terms, it is a trifle—0.004% of reserves—and Michael Saylor and voices like Adam Back presented it as simple balance sheet flexibility, not capitulation. They have a point: selling a tiny fraction to meet a financial payroll is not a bearish pivot.
But the signal is disproportionate to the size. For years, "never sell" was the central dogma of the narrative. That the company touches its BTC—however little and for however good a reason—to cover a preferred dividend confirms exactly the mechanism described by the discount theory: when capital markets close (stock at a discount, premium dead), mandatory payments must be covered from somewhere, and the only place is the Bitcoin vault. We analyze that specific move and its interpretation in Saylor's BTC sale as inoculation, and the mechanics of the preferreds that create that payment obligation in Strategy's STRC/STRK/STRF preferred shares explained.
STRC, Strategy's "Stretch" preferred designed to trade near its $100 par via a dividend that rises when the price falls, hit an intraday all-time low of $82.53 on June 18, 2026 (closing near $89), according to Crypto Briefing and CoinDesk. The most revealing signal is not the BTC sale, but the paper it can no longer place. To sustain STRC, Strategy has already raised the dividend from an initial 9% to 11.50% annually, and even so, the declared coverage for that payment dropped from 71 years in November 2025 to about 31-32 in June 2026 (Protos). The detail that closes the circle: with STRC below 100, the company cannot issue more shares of that series above par, so the self-financing tap used to buy Bitcoin clogs just when it is needed most. The preferred that funded the purchases has become the burden forcing the sales.
Is there systemic risk for the price of Bitcoin?
This is the question making regulators and institutions nervous, and where precision is necessary.
First, the size. As of mid-2026, listed companies hold a combined total of roughly 1.15 to 1.17 million BTC, according to counts from Bitget and other aggregators—between 5.3% and 5.6% of the total 21 million supply. Strategy alone concentrates over 840,000 coins (May-2026 data), the vast majority of that total.
The risk described by Coinbase Institutional (2026) is a negative feedback loop: if mNAVs fall, some treasuries are forced to sell BTC; those sales pressure the price downward; a lower price further deteriorates balance sheets and mNAVs; which forces more sales. In an adverse scenario, selling pressure from treasuries would drag down both their stock price and that of Bitcoin itself. Standard Chartered, along the same lines, lowered its BTC price targets throughout 2026 and warned that corporate buying, previously a pillar of demand, had stalled because companies no longer had the valuation or the incentive to accumulate aggressively.
Catastrophism should be tempered. The extreme concentration in Strategy—which has declared reserves for several quarters of dividends and a founder notoriously reluctant to sell—means a mass liquidation scenario is neither mechanical nor imminent. Its capital structure also matters: after repurchasing $1.5 billion in convertibles (operation completed May 25, 2026), it carries roughly $6.7 billion in convertible debt (post-repurchase) and over $15.5 billion in its set of preferred shares (press release May 26, 2026), whose coupons and dividends are the mandatory payments straining the balance sheet when the premium disappears. The real risk is not a single mega-seller, but the long tail of small, leveraged treasuries that, trapped under 1x and with payments to cover, could be forced to sell simultaneously: the sum of many small spirals, not the implosion of the large one.
What are the lessons for understanding these companies?
The central lesson is that a Bitcoin treasury company is not a clean proxy for Bitcoin: it is a leveraged bet on the premium. While the market paid it, it multiplied the upside. Without it, what remains is a wrapper that can be worth less than its contents and that, in some cases, has incentives to sell those contents.
To the headline question—"is a Bitcoin treasury company safe?"—the honest answer is "it depends on the balance sheet and the mNAV." A firm with a premium, no mandatory debt, and an operating business is in a very different place than a leveraged BTC vault trading at 0.80x with a preferred dividend to pay. The mathematics of the discount is what separates them, and it is independent of the price of Bitcoin: the engine reverses at 1x regardless of what happens to BTC. Leverage cuts both ways; the premium was the product, and products, when the market stops paying for them, are discounted.
