Two of the largest non-ETF holders of Bitcoin (BTC) are now under simultaneous balance-sheet pressure, and the market is treating them as unrelated stories. They are not. Miners sold roughly 32,000 BTC while spot sat below production cost, and the digital asset treasury (DAT) sector — the second structural bid of this cycle — has now lost the mechanism that made it a buyer at all. Metaplanet, Japan’s largest corporate Bitcoin holder, is funding purchases with debt and options income while its own equity trades at a record discount to the coins it owns.
The capital engine only runs at a premium
The metric that governs the entire model is mNAV — the ratio of a treasury company’s market capitalisation to the dollar value of the crypto on its balance sheet. Above 1.0x, the company can issue shares at a premium and buy more Bitcoin per existing share, which is accretive. Below 1.0x, issuing equity to buy coins destroys value for existing holders: the company sells a dollar of stock to acquire less than a dollar of Bitcoin.
That threshold has now been breached across most of the sector. Strategy Inc (MSTR), the firm that invented the template under Executive Chairman Michael Saylor, saw its enterprise mNAV fall below 1.0 in June 2026, erasing a premium that once ran to seven times net asset value. Metaplanet’s mNAV is down 96% from its July 24, 2024 level, according to Protos, with the stock 87% below the all-time high set in July 2025.
The scale is not marginal. Roughly 200 public companies hold about $96 billion in Bitcoin and 68 treasuries hold more than $22 billion in Ethereum (ETH), per DL News, which counted only a handful of 195 treasury companies trading above net asset value.
Buybacks replace coin purchases
Metaplanet’s response is the one the mNAV arithmetic dictates. The company disclosed plans to repurchase up to 150 million common shares, equal to 13% of issued shares excluding treasury stock, explicitly to address the mNAV decline. When a share trades below the value of the Bitcoin backing it, buying the share is a cheaper way to acquire Bitcoin per share than buying Bitcoin.
It has not stopped accumulating outright — the firm added 2,823 BTC in the second quarter of its 2026 financial year, taking holdings to roughly 43,000 coins worth about $2.6 billion. But the funding has shifted to borrowed money and options premium rather than equity issuance, which converts a self-reinforcing flywheel into a leveraged carry trade with a maturity schedule attached.
That is the part the sector has not priced. Equity-funded accumulation has no repayment date. Debt-funded accumulation does.
What the discount does to supply
Here is the synthesis the individual stories miss. Through 2024 and most of 2025, DATs and spot ETFs were the two structural bids absorbing coins that miners issued and sold. Miners are now distributing into weakness. DATs have lost the ability to issue equity into strength. Both legs of the demand structure that offset miner supply have weakened in the same quarter, while $2.7 billion exited Bitcoin and Ether funds in a rotation toward XRP and HYPE products.
This does not mechanically force DAT selling. Most have no covenant requiring liquidation. But it removes a buyer that was, for two years, price-insensitive by design — at the same moment the newest cohort faces its first refinancing decisions.
The counter-case deserves stating plainly. A discount is only fatal if the company needs to raise. Firms with cash-generating operating businesses beneath the treasury can hold through a discount indefinitely, and consolidation may prove healthy: fewer, better-capitalised vehicles with genuine balance sheets rather than 195 competing wrappers around the same asset.
“The premium era is over,” said John Fakhoury of Stacking Sats, speaking to DL News. “We’re entering a phase where only disciplined structures and real business execution are going to survive.”
What to watch
Three signals will show whether this is a repricing or a structural unwind. First, whether any DAT actually sells coins to fund a buyback rather than borrowing — the first confirmed instance would reset how the sector is underwritten. Second, whether merger activity begins, which several practitioners expect. Third, whether the discount persists through a Bitcoin rally; a premium that fails to return on strength would confirm the equity-issuance channel is closed rather than merely shut for the cycle.
For exchanges and custodians the consequence is narrower but immediate: treasury companies that switch from accumulating to repurchasing move their flow from spot desks to equity market-making, and custody balances stop growing — a shift visible alongside the repricing of on-chain asset concentration.
