Bitcoin Treasury Companies: The Corporate BTC Accumulation Trend
More and more public companies are turning Bitcoin into their core balance sheet strategy: 2026 brings record amounts of BTC onto corporate books, but also the first serious cracks in the model that started it all.
Table of contents:
When MicroStrategy first put part of its balance sheet into Bitcoin in 2020, it looked like an experiment by one unusual software company.
Six years later, that experiment has become an entire category on the stock market.
Today, nearly 200 public companies hold Bitcoin as part of their corporate strategy, and the total value of those reserves exceeds $100 billion.
In 2026, that model is going through its biggest test yet.
What Are Bitcoin Treasury Companies
A Bitcoin treasury company, often called a "DAT" (digital asset treasury company) in industry jargon, is a publicly traded company whose core corporate strategy is buying and holding Bitcoin on its balance sheet long-term, rather than selling products or services.
Some of these, like former MicroStrategy, now operating under the name Strategy, still formally run a software business, but that revenue stream has long since become secondary to the value of their Bitcoin reserves.
Mining companies, on the other hand, deliberately hold onto part of the Bitcoin they mine instead of selling it, keeping it as a treasury asset.
The idea is simple: instead of holding cash that loses value to inflation, these companies redirect part or most of their capital into Bitcoin, betting on its long-term appreciation and limited supply.
How Much Bitcoin Do Public Companies Hold Today
According to data from specialized services tracking corporate reserves, by September 2026, nearly 200 public companies collectively held over 1.29 million BTC, worth more than $100 billion at the time and representing roughly 6% of Bitcoin's total future supply. The structure of this market is highly concentrated:
Strategy (MSTR)
Strategy remains the undisputed leader with more than 840,000 BTC on its balance sheet, at an average purchase price well below market value. Michael Saylor remains synonymous with this strategy.
MARA Holdings
A major mining operator that deliberately holds part of the Bitcoin it mines as a treasury asset, with tens of thousands of BTC on its balance sheet, alongside occasional sales to fund operations.
Twenty One Capital (XXI)
A company formed through a merger with a special purpose acquisition company (SPAC), backed by Tether and SoftBank, holding more than 43,000 BTC.
Metaplanet
A Japanese company that describes itself as "Asia's MicroStrategy" and is the third-largest corporate Bitcoin holder in the world, with around 43,000 BTC.
Tesla
A smaller but symbolic player with roughly 11,500 BTC purchased at a far lower price than today's market value.
The model is also expanding beyond Bitcoin. Some companies, like SharpLink, have built a comparable strategy around Ether, so the term "digital asset treasury companies" is increasingly used more broadly, not just for Bitcoin.
How the "Flywheel" Model Works
At the heart of the entire strategy is a metric called mNAV (market Net Asset Value), the ratio between a company's market capitalization and the value of the Bitcoin it holds.
When a stock trades at a premium (mNAV above 1), the company can issue new shares at that premium price, invest the capital raised into additional Bitcoin, and thereby increase the amount of Bitcoin "belonging" to each existing share.
In a rising market, this mechanism acts as an amplifier: Bitcoin's price goes up, the premium goes up, the company buys even more, and shareholders profit twice over.
It's precisely this "flywheel" effect that allowed Strategy to raise more than $25 billion in capital in 2025, making it one of the largest corporate stock issuers in the US that year.
Cracks That Surfaced in 2026
A model that works brilliantly while the market is rising becomes far more vulnerable when it stagnates or falls, and that's exactly what happened during 2026.
The premium that powered the entire system has largely disappeared: Strategy's mNAV fell from nearly 4x in late 2024 to close to 1, and a number of smaller treasury companies started trading below the value of the Bitcoin they hold.
This raises several serious concerns:
Dilution Without Benefit
Once the premium disappears, issuing new shares to buy Bitcoin stops increasing Bitcoin per share and simply starts diluting existing shareholders.
Risk of Forced Selling
Analysts warn that a combination of debt, preferred dividend payments, and an mNAV falling below 1 could force some smaller treasury companies to sell part of their Bitcoin reserves, or even shut down entirely.
Systemic Risk to the Market
Since dozens of companies base their value on the same model, a drop in Bitcoin's price hits all of them at once, raising the possibility of a negative spiral: falling Bitcoin prices push mNAV lower, which increases selling pressure, which pushes the price down further.
Lack of a "Real" Business
Critics, including Wall Street analysts, point out that most of these companies generate no revenue or profit outside their Bitcoin position, their value depends entirely on the movement of a single asset and on the market's confidence in management.
What This Means for Investors and for the Broader Bitcoin Story
The Bitcoin treasury company phenomenon illustrates the broader institutionalization of Bitcoin well, its move from the margins into a tool of corporate balance sheet management.
At the same time, 2026 makes it clear that buying shares in a treasury company is not the same as buying Bitcoin: investors in that case take on not just exposure to BTC's price, but also management risk, capital structure risk, debt, and the risk of future access to capital markets.
For regulated markets within the EU, these models further underscore the importance of transparency and a clear distinction between direct ownership of crypto assets and exposure through corporate vehicles, a topic that's becoming increasingly relevant in the context of retail investor protection.
Bitcoin treasury companies certainly aren't going to disappear overnight. The biggest players, like Strategy, still hold hundreds of thousands of Bitcoin and can "survive a long winter."
But 2026 has shown that this is a strategy with two faces: while the market rises, it accelerates Bitcoin accumulation on corporate balance sheets, but once the momentum stops, the same mechanism can turn against those who built the most on it.
