The Companies That Borrowed to Hoard Bitcoin Are Now Being Forced to Sell It
The cleverest trade in crypto last year has quietly become the most dangerous one. Companies stacked Bitcoin onto their balance sheets, paid for it by selling their own stock at a fat premium, and watched their share prices climb faster than the coin itself. That was 2025. In 2026 the same machine runs backward, and a handful of these firms are now selling the very Bitcoin they once vowed never to touch.
Digital asset treasury companies — public vehicles built for the single purpose of hoarding crypto — are learning that financial leverage cuts both ways. The premium that funded the whole strategy has evaporated. What's left is a balance sheet full of a falling asset and a stock market that no longer wants to pay extra for the privilege of owning it secondhand.
The premium was the entire business model
Strip away the slogans about "digital gold on the balance sheet" and the trade was an arbitrage on investor enthusiasm. A company would trade above the value of its crypto — sometimes at two or three times the worth of the coins it held — then issue fresh shares into that excitement and use the cash to buy more Bitcoin. Each round added coins per share. The premium printed money, and the money bought more premium.
The number that governs all of this is mNAV: market net asset value, the ratio of a company's market capitalization to the dollar value of the crypto it holds. Above an mNAV of 1.0, a firm can sell new shares and buy more crypto, growing each share's backing; below 1.0, the trade reverses and every share sold shrinks what's behind it. One number separates a buyer from a forced seller. Most of the sector now sits on the wrong side of it.
By June, the discount had become the norm rather than the exception. Of the 18 largest treasury vehicles tracked by 21Shares, 13 traded below the market value of their own holdings, and roughly 40% of the top 100 Bitcoin treasury firms were valued at less than the net asset value of their coins. When the wrapper is worth less than what's inside it, the magic trick stops working.
When the loudest bull calls the top
You know a phase is over when its champions start writing the obituary. Tom Lee, chairman of the Ethereum treasury company BitMine and one of crypto's most reliable optimists, said plainly that the "bubble has burst" for digital asset treasuries as many slipped below net asset value. That was last autumn. The months since only deepened the point.
The damage to shareholders has been brutal and specific. Shares of crypto-hoarding firms fell by a median of around 62% over the past year — far worse than Bitcoin's own slide — and investors now describe the "premium era" as finished. The stocks were supposed to be a turbocharged way to own Bitcoin. They turned out to be a turbocharged way to own its downside.
Bitcoin did its part to make things worse. After crossing roughly $126,000 at its October 2025 peak, it fell close to half from that high. A 50% drawdown is survivable for a holder with no debt and no shareholders demanding a story. It is a different thing entirely for a company that borrowed against those coins and sold stock on the promise they would only ever rise.
The spiral nobody wants to name
Here is the mechanism that keeps treasury skeptics awake. A firm trading below its crypto value can no longer raise cheap equity to buy more. If it also carries debt — convertible notes, term loans, anything with a maturity date — it may have to sell coins to meet obligations. Selling pressures the price. A lower price pushes more treasury firms below their net asset value. Which forces more selling. The polite term is deleveraging. The impolite one, now circulating among analysts, is the spiral of doom.
It is not hypothetical. Smaller players have already been pushed into selling at a loss to keep the lights on, and even larger names have liquidated holdings to clear debt. MARA Holdings sold off more than 15,000 BTC to retire convertible debt, while Nakamoto Holdings sold Bitcoin at roughly a 40% realized loss to fund operations, its shares down about 99% from their 2025 peak. The "never sell" ethos is a luxury good. It requires a balance sheet that can afford it.
The ETF quietly removed the reason to pay a premium
There's a deeper reason the premium was always living on borrowed time, and it has nothing to do with leverage. When the first treasury companies launched, buying a public stock was one of the only ways an ordinary brokerage account could get Bitcoin exposure at all. Scarcity of access justified the markup. You paid extra for the wrapper because the wrapper was the door.
That door is now wide open. Regulated spot Bitcoin ETFs give investors direct exposure with low fees and none of the corporate baggage, which raises an awkward question for anyone holding a treasury stock at a premium: why pay more for indirect, leveraged, debt-laden Bitcoin when a cheaper, cleaner version trades on the same exchange? An ETF can't go bankrupt. It can't be forced to sell at the bottom to service a convertible note. It just holds the coin.
The treasury bulls have an answer — that a well-run company can grow its Bitcoin-per-share faster than a static fund ever could, turning the balance sheet into a compounding engine. That's true precisely while the premium holds and capital stays cheap. It stops being true the instant the stock falls below its net asset value, at which point the "engine" runs in reverse and the ETF's boring simplicity starts to look like a feature. The arrival of easy direct access didn't kill the treasury trade. It removed its excuse.
The strong survive, and that's the actual story
The case for the defense is real, and worth stating fairly. Not every treasury company is a casualty. The firms that funded themselves with patient, long-dated capital rather than short-fuse debt can sit through a drawdown without becoming forced sellers. They bought Bitcoin as a conviction position, not as fuel for a share-price flywheel, and a falling market is exactly when conviction is supposed to be tested. For them, mNAV below 1.0 is uncomfortable, not fatal.
That distinction is the point. The shakeout isn't proving that holding Bitcoin on a corporate balance sheet is foolish. It's proving that holding Bitcoin with borrowed money and a promise of perpetual premium was always a bet on sentiment wearing the costume of a treasury strategy. The companies confusing the two are the ones being marched to the exit.
Scale matters here too, against the panic. Even with the carnage, the category remains large. Public companies still hold well over a million Bitcoin between them, and most of that supply sits with firms that aren't being forced to sell. The risk isn't that corporate Bitcoin vanishes. It's that the marginal, overleveraged holders dump into a thin market and make a bad quarter worse for everyone.
What 2026 is really clearing out
Expect consolidation rather than extinction. Healthy treasuries with cheap capital will buy distressed ones for less than the value of their coins — acquiring Bitcoin at a discount by acquiring the company that holds it. Some firms will abandon the pure-hoard model entirely and pivot toward operating businesses that throw off cash, because a treasury that produces nothing has no defense when its premium disappears. The survivors will look less like leveraged Bitcoin ETFs and more like companies that happen to own a lot of crypto.
The uncomfortable lesson for the next cycle is that a treasury strategy is only as sound as its weakest financing assumption. As long as Bitcoin rose and equity stayed cheap, the model looked like genius. The moment both reversed, it revealed itself as a carry trade with a mission statement.
So the question worth asking now isn't whether Bitcoin recovers — it has buried plenty of obituaries before. It's whether the next batch of executives, watching the survivors emerge leaner and unlevered, learns the right lesson, or simply waits for the premium to return so the whole machine can be rebuilt and broken again.
