Bitcoin has gained significant traction among public companies, with several firms amassing large portfolios. As of August 2025, Strategy (formerly MicroStrategy) leads with 628,946 BTC, valued at over $73 billion, marking it as a primary corporate holder. Other notable companies include Marathon Digital, which holds 50,639 BTC; Twenty One, expected to hold 43,514 BTC; and Bitcoin Standard Treasury Company with over 30,000 BTC anticipated by late 2025. Additionally, Riot Platforms holds 19,273 BTC, and CleanSpark has 12,703 BTC. Coinbase and Tesla round out the list with 11,776 BTC and 11,509 BTC, respectively. This trend reflects a significant institutional shift towards Bitcoin as a mainstream reserve asset, a notion once deemed laughable. The cumulative Bitcoin held by these firms now constitutes nearly 4.5% of the total Bitcoin supply, indicating a profound transformation in corporate financial strategies and investment portfolios.
