As Bitcoin continues to cement itself as a mainstream financial asset, top companies are adding it to their portfolios. This is a windfall for Bitcoin as the premier cryptocurrency maintains market dominance. As of 2025, public companies own more than 3.3% of the Bitcoin in circulation — roughly 693000 BTC. Here’s the list of the top 10 companies accounting for more than 90% of this figure.
Formerly known as MicroStrategy, Strategy, a business intelligence specialist, mobile software developer, and cloud-based service provider, tops this list with a staggering 531,644 Bitcoin as of April 2025. This amount makes it the largest BTC holder by a big margin. To put this into perspective, the other companies have a little above 161,000 Bitcoin out of approximately 693,000 owned by all public companies.
MicroStrategy made the first purchase in late 2020, accumulating 21,454 BTC worth $250 million. In 2021, the company bought over 50,000 BTC, boosting its portfolio significantly. From 2022 onward, the company increased its Bitcoin holdings, spending over 10 billion in 2024 alone and adding another 22,000 BTC. With BTC trading at $94,000, MicroStrategy’s Bitcoin portfolio is valued at over $50 billion.
Marathon Digital Holdings, a publicly owned United States company, is next on this list with about 47,531 BTC. MARA is a digital asset technology that deals with cryptocurrency mining, digital asset generation, and other blockchain-related activities. MARA is the second-largest BTC holder after Strategy. 2024 was Marathon Digital Holdings’ most active year in Bitcoin (BTC) accumulation. In 2024 alone, the company’s portfolio doubled, growing from 20,000 to 40,000. It may repeat a similar buying pattern in 2025 since the top Bitcoin holder has already acquired more than 7,000 BTC four months into the year.
Presently valued at over $4.5 billion, Marathon Digital Holding is set to keep increasing its portfolio since it’s one of the biggest miners in the world.
Riot Platforms is a big name in the crypto world, especially in its mining aspect. In its April report, Riot Platforms stated that it now has 19,223 BTC as of May 2025. The news report from the giant holder attributes some of its BTC to mining activities. Riot Platforms runs North America’s largest Bitcoin mining facility at press time. The company doesn’t focus on other types of cryptocurrencies; it focuses only on Bitcoin. With its specific interest in the premier cryptocurrency, Riot Platforms’ Bitcoin size may soon surge.
Another U.S.-based mining company on this list is CleanSpark. Ranked the fourth company with the largest Bitcoin holding, CleanSpark has about 12,000 BTC worth over $1.2 billion. CleanSpark has been expanding its mining facilities since 2024, when it acquired three Bitcoin mining facilities in Mississippi to increase its mining activities.
CleanSpark gets a decent amount of Bitcoin through mining. According to a report, in 2024, the company mined a little over 400 BTC in just one month — a feat analysts would have deemed impossible. CleanSpark has been keen on growing its Bitcoin bag mainly through mining rather than buying, as many other top holders do.
Tesla is synonymous with electric cars and technology as a whole. In 2020, however, Tesla moved to buy Bitcoin and started talks of using crypto as a payment option. The company had Bitcoin valued at $1.5 billion in the 2020 fiscal year. The CEO, Elon Musk, played a huge part in the firm’s journey to amass Bitcoin. By 2021, Elon Musk hinted at Tesla having a sizable number of Bitcoins.
Although Tesla sold one-tenth of its Bitcoin holdings at some point to verify the coin’s liquidity, it currently owns 11,509 BTC. It’s unclear if the number will increase anytime soon since Elon Musk cited environmental concerns as the reason Tesla will stop accepting Bitcoin until there are cleaner and safer ways to mine the digital asset.
Hut 8 Corporation is a Canadian-based company with a decent share of the Bitcoin in circulation. It is also a Bitcoin mining company that invests heavily in expanding its mining facilities to compete at a high level. In 2023, it merged with a US-based mining company to boost mining activities. Hut 8 Corporation holds over $870 million worth of Bitcoin, equivalent to 10,2654 BTC.
Current mining efforts and dedication to increasing the value of its BTC indicate a possible increase in Hut 8’s crypto portfolio. Additionally, the company leverages its mining stockpile to generate income through a yield strategy.
Galaxy Digital Holdings is a top crypto and blockchain solution provider. Known for managing assets, venture investing, offering trading services, and more, Galaxy Digital Holdings is ranked as one of the largest Bitcoin holders in 2025. With 11,242 BTC, the crypto company is part of institutions with over $1 billion worth of Bitcoin. Starting in 2022, Galaxy Digital Holdings acquired thousands of BTC, then added 850 BTC in 2024. According to a financial statement, the crypto solution company added to its portfolio to bring its tally above 11,000 BTC.
The latest additions include assets used as collateral and borrowed digital assets. Galaxy Digital Holdings manages a U.S. spot Bitcoin ETF alongside notable firms.
Founded in 2009 by Jack Dorsey, former Twitter owner and crypto enthusiast, Block is a financial technology and financial services firm registered in the United States. Block started investing in Bitcoin as far back as 2020, spending $50 million to test the waters. Four years later, the company has 8,485 Bitcoins to its name. With BTC trading slightly above $100,000, Block’s portfolio is worth arguably $900 million.
Like Tesla, Block is also owned by a pro-crypto CEO, Dorsey, who has always been vocal about the capabilities and importance of cryptocurrency in the modern world. Little wonder Block has dedicated its resources to developing mining chips for Bitcoin and a cryptocurrency wallet. A report from Block also reveals the firm is focused on improving its Bitcoin products and services by reinvesting part of its profit.
Coinbase, a big name in the crypto industry, is next on the list with 6,885 BTC. With a Bitcoin portfolio worth almost $700 million, Coinbase tripled its holding within the last four years after making its first purchase in 2021.
Coinbase is big on Bitcoin products and services. Lending Bitcoin is one such service. Although the crypto firm once halted this service, it resumed recently. The Coinbase-wrapped Bitcoin product is a notable innovation from the crypto giant, further emphasizing its commitment to Bitcoin adoption and spread.
Metaplanet holds 4,425 BTC, making the management company the 10th on this list. Metaplanet is popularly known for its hotel business and investment in real estate. In recent years, the company has diversified into crypto. NFT-related investments, Web3 developments, and blockchain services are some fields Metaplanet has been exploring of late. Apart from the sizable Bitcoin holding, the company named one of its hotels “ The Bitcoin Hotel. “ Listed on the Tokyo stock exchange, Metaplanet is one of the top public companies with significant Bitcoin purchases within the last 7 months. It acquired more than 4100 BTC between the 3rd quarter of 2024 and the second quarter of 2025.
