Bitcoin Treasury Companies: The Complete List of Public Firms Holding BTC

Public companies now hold approximately 1.19 million Bitcoin between them, equivalent to roughly 5.7% of the total Bitcoin supply that will ever exist. Strategy alone, the company formerly known as MicroStrategy, owns nearly 800,000 of those coins. The corporate Bitcoin treasury has gone from a single-company experiment in 2020 to a recognised category of public-market exposure, with dozens of firms now structuring their balance sheets around BTC accumulation.

This guide covers what a Bitcoin treasury company actually is, lists the largest public holders, and explains how their strategies differ in practice.

A Bitcoin Treasury Company Holds BTC as a Reserve Asset

A Bitcoin treasury company is a publicly traded firm that holds Bitcoin on its balance sheet as a strategic reserve. The model was effectively created by Michael Saylor at MicroStrategy in August 2020, when the company announced it would convert a portion of its corporate cash into Bitcoin as a hedge against currency debasement. The thesis was that fiat reserves lose value over time, while Bitcoin's fixed supply made it a more durable long-term store of value.

That single decision evolved into a full corporate strategy. Strategy now raises capital through equity issuance and convertible debt, then deploys that capital into Bitcoin purchases, increasing the BTC owned per share over time. Other companies have followed, either fully restructuring around the treasury model or simply adding Bitcoin to existing balance sheets as a portion of their reserves. The shared logic is the same: Bitcoin is treated as a strategic long-term asset rather than a speculative trade.

Three Distinct Strategies Sit Behind These Holdings

The list above looks uniform on the surface, but the strategies behind the holdings vary significantly. Three broad categories cover most of what is happening.

Pure treasury companies like Strategy, Twenty One Capital, BSTR and Metaplanet are structured almost entirely around BTC accumulation. They raise capital through equity issuance and convertible debt, then deploy it into Bitcoin, with the explicit goal of increasing BTC owned per share over time. Their stock prices effectively trade as a leveraged play on the BTC price, often at a premium to net asset value when investor sentiment is strong.

Bitcoin miners like MARA, Riot, Hut 8 and CleanSpark accumulate BTC as a by-product of their core business. Holdings can grow through mining output or shrink when companies sell to fund operations, repay debt or finance expansion into other areas such as AI infrastructure. MARA, for example, sold around 15,133 BTC in early 2026 to retire debt. Miner treasuries are therefore less predictable than pure treasury company holdings.

Operating companies with BTC reserves like Tesla and Coinbase hold Bitcoin as one component of a broader treasury strategy. Their core businesses are not crypto-native, but they have allocated a portion of cash reserves to BTC for the same reasons as Strategy: hedging against currency debasement and gaining exposure to a long-duration asset.

The Risks Investors Often Underestimate

The treasury model has a few structural risks that are easy to miss when prices are rising. Treasury companies that rely on continuous capital raises to fund BTC purchases are exposed to equity issuance fatigue, where the market becomes reluctant to absorb new shares. Convertible debt creates obligations that must be serviced regardless of where the Bitcoin price sits. A sustained BTC drawdown can compress mNAV premiums to near zero, hurting the stock price even when BTC holdings are unchanged.

Concentration risk is the other side of the same coin. Strategy holds nearly 5% of the total Bitcoin supply alone. A forced sale, whether driven by debt servicing, regulatory action or shareholder pressure, could move the market materially. For the broader category, the question is whether the corporate treasury thesis holds up through a full Bitcoin cycle, since most of the public treasury companies have only operated through the post-2023 recovery and not a deep multi-year drawdown.

What Comes Next for the Treasury Category

The treasury company category is now mature enough that institutional infrastructure is built around it. ETF managers track them. Index providers include them. Analysts cover them as a distinct asset class. The next chapter is likely to involve more non-US firms joining the model, more Ethereum and Solana treasury companies following the same playbook, and more scrutiny of how these vehicles behave when the underlying asset moves sharply in either direction.

The thesis Saylor put into practice in 2020 has now been adopted by over 100 public companies. Whether the next 100 see it as a generational opportunity or a cautionary tale depends on what happens to BTC prices over the next two years.
