Corporate treasuries around the world have increasingly allocated BTC to their balance sheets. By 2026, dozens of publicly traded companies have adopted what’s known as a Bitcoin treasury strategy — holding large amounts of Bitcoin to preserve value, hedge inflation, or signal confidence in digital assets.
This article breaks down the largest Bitcoin treasury companies in 2026, and takes a look at their strategies, as well as how much Bitcoin they each hold:
- Strategy (Formerly MicroStrategy) – Market-leading Bitcoin treasury, aggressive accumulation, long-term digital asset store
- MARA Holdings, Inc. (Marathon Digital) – Bitcoin mining-focused, operational retention, corporate treasury accumulation strategy
- Twenty One Capital – Digital finance corporate, Bitcoin reserve asset, investor-friendly accumulation approach
- Metaplanet Inc. – “MicroStrategy of Asia,” strategic BTC holding, long-term asset allocation
- Bitcoin Standard Treasury Company – Corporate Bitcoin acquisition, value-aligned strategy, substantial treasury holdings
1. Strategy (Formerly MicroStrategy)
Bitcoin Held: ~687,410 BTC (≈ 3.27% of total Bitcoin supply)
At the top of the corporate Bitcoin holder list in 2026 is Strategy, the company formerly known as MicroStrategy (ticker: MSTR). Under CEO Michael Saylor’s leadership, the enterprise software firm shifted its treasury strategy in 2020 to prioritize Bitcoin as its primary store of value. Since then, Strategy has aggressively accumulated BTC through debt raises and equity issuance.
By early 2026, Strategy holds an estimated 687,410 BTC, making it by far the largest corporate Bitcoin holder in the world. This represents more than 3% of the total 21 million Bitcoin that will ever exist. Strategy’s large treasury also makes it one of the most visible bellwethers for institutional interest in Bitcoin.

2. MARA Holdings, Inc. (Marathon Digital)
Bitcoin Held: ~53,250 BTC
MARA Holdings, Inc., commonly known as Marathon Digital, is a prominent Bitcoin mining company that transitioned into holding mined Bitcoin in its corporate treasury. While Marathon’s primary operation remains mining — generating BTC through data centers — the company has also kept a big portion of its production as treasury reserves.
As of late 2025/early 2026, Marathon reported holding around 53,250 BTC, making it one of the largest Bitcoin treasuries among mining and public companies. This sizeable stash was gathered through operational output and strategic retention rather than acquisition in open markets.
3. Twenty One Capital
Bitcoin Held: ~43,514 BTC
Twenty One Capital (ticker: XXI) is a corporate entity that has adopted a Bitcoin treasury strategy similar to Strategy but on a smaller scale. It’s focused on accumulating Bitcoin as a reserve asset and also operates in the broader digital finance ecosystem. With around 43,514 BTC on its balance sheet by early 2026, Twenty One Capital ranks among the top 3 BTC-holding public companies.
The company has attracted attention for its investor-friendly approach to Bitcoin accumulation and integration with financial markets.
4. Metaplanet Inc.
Bitcoin Held: ~35,102 BTC
Metaplanet Inc. is a Japanese firm dubbed by some analysts as the “MicroStrategy of Asia.” While originally diversified in sectors such as hospitality and technology, Metaplanet adopted a strategic Bitcoin holding approach — boosting BTC allocations as a long-term asset.
By 2026, the company reportedly holds around 35,102 BTC, expanding Bitcoin treasury strategies beyond North America.
5. Bitcoin Standard Treasury Company –
Bitcoin Held: ~30,021 BTC
The Bitcoin Standard Treasury Company is another key player among publicly traded firms holding Bitcoin. It focuses on acquiring and retaining BTC with the aim of aligning corporate value with Bitcoin’s long-term trajectory.

From Strategy’s market-leading treasury to the mining-driven reserves of MARA and the diversified holdings of players like Twenty One Capital and Metaplanet, these companies prove that institutional Bitcoin adoption isn’t slowing — it’s accelerating.
