A Bitcoin treasury company is a public company built around holding crypto on its balance sheet, giving investors exposure through a stock instead of a wallet. Buyers do not need to handle custody, private keys, or on-chain transfers. They buy shares, and the company holds Bitcoin or ether.
These firms are often described as digital asset treasury companies, or DATs. Unlike a conventional listed business that is valued on revenue and operations, a treasury company is centered on accumulating crypto, often by raising money in capital markets and using the proceeds to buy more coins. According to the source material, the model was scaled first by Michael Saylor’s Strategy, formerly MicroStrategy, and by 2026 it had spread to more than 200 companies with combined crypto holdings worth well above $100 billion.
The model works only when the stock trades above its holdings
The core mechanism is simple but easy to miss. If a company’s shares trade above the value of the crypto it already owns, the company can issue new shares, raise cash, and buy additional Bitcoin or ether. Because those shares were sold at a price richer than the value of the underlying holdings, existing shareholders can end up with more crypto exposure per share rather than less.
That is the flywheel behind the sector. A higher coin price lifts the value of the balance sheet, which can push the stock higher, which improves fundraising terms, which funds more crypto purchases. Some companies highlight this by tracking how much crypto they hold on a per-share basis. The structure is powerful in an upcycle. It is also fragile, because the whole process relies on one condition: the stock must keep trading at a premium.
mNAV tells investors whether the engine is alive or stalling
The main valuation metric is mNAV, or multiple of net asset value. NAV in this context is the market value of the crypto held by the company. If the company’s market capitalization is above the value of its coins, mNAV is above 1 and the stock trades at a premium. If market value falls below the value of those holdings, mNAV drops under 1 and the stock is at a discount.
This distinction is not a side detail. It determines whether the structure can keep compounding. At a premium, issuing stock can support growth in crypto per share. At a discount, issuing new equity becomes destructive for existing holders because new buyers would receive more underlying crypto value for each dollar invested than current shareholders already have. The source notes that through late 2025 and into 2026, a growing number of treasury companies slipped toward or below NAV, and their growth engines started to stall.
Convertible debt and preferred stock increase both upside and strain
Many treasury companies do not rely on common stock alone. They also use convertible debt, bonds, and preferred shares to raise more capital and increase their crypto exposure. In a rising market, this structure can magnify gains because it gives the company more firepower than ordinary equity issuance by itself.
The trade-off is fixed obligation. Debt must be serviced, and preferred dividends do not disappear because Bitcoin falls. The source says that in June 2026, a group of Bitcoin-backed preferred instruments dropped sharply below their intended stable value in a single session driven by leverage selling. That move served as the first real stress test for the so-called “digital credit” structure marketed as high-yield income backed by crypto-heavy balance sheets.
Concentration, reflexivity, and discount risk define the category
The risk profile follows directly from the structure. First, these companies are highly concentrated, with most of their value tied to one volatile asset. Second, they are reflexive. On the way up, rising crypto supports the stock and opens cheap financing channels; on the way down, weaker crypto drags the stock lower, makes capital raising harder, and removes a source of buying that had supported the underlying asset.
The most distinctive danger is the discount trap. Once a treasury company falls from premium to discount, the mechanism that justified the model starts to break. In a severe downturn, especially where leverage and preferred obligations are layered in, a company can face pressure to sell holdings and turn balance-sheet stress into real selling pressure. The source also notes that stronger names with deeper liquidity, and in some cases staking income, have held up better than weaker copycats. Even so, a treasury stock is not the same as owning spot Bitcoin or a Bitcoin ETF. It is a leveraged equity wrapper whose behavior depends on valuation, market access, and capital structure.
