Bitcoin adoption among public companies reached new levels in early 2025, with a growing number choosing the cryptocurrency as a core treasury reserve asset. And still, Saylor’s Strategy (formerly known as MicroStrategy) holds a commanding lead in this trend, according to data compiled by Coingecko and shared on March 27. The business intelligence firm holds a staggering 506,137 BTC, worth over $44.2 billion at current prices (near $87k/BTC.)

Strategy Inc.’s Dominance: How Big Are Its Bitcoin Holdings?

Strategy Inc.’s Bitcoin position is substantial by multiple measures. Its holdings represent roughly 2.5% of Bitcoin’s entire current circulating supply. These holdings also account for nearly 84% of the combined Bitcoin reserves held just by the top 10 publicly traded corporate holders. 

The company, heavily influenced by Executive Chairman Michael Saylor’s Bitcoin advocacy, aggressively built this position through calculated debt offerings and equity sales starting in 2020. Only one modest sale of 704 BTC, reported in December 2022, was conducted, primarily for tax optimization purposes. This sheer scale places Strategy Inc. in a league of its own among corporate Bitcoin accumulators.

How Do Bitcoin Miners Benefit from Holding BTC?

Beyond Strategy Inc., Bitcoin mining firms represent another major category of corporate BTC holders. Companies like Marathon Digital (currently holding ~26,842 BTC) and Galaxy Digital (~15,449 BTC) benefit directly from holding the asset they produce. They mine Bitcoin at operational costs significantly below its market value. 

This model allows them to build substantial asset reserves without the typical capital expenditure required for direct market purchases. As mining hardware and energy efficiency improve over time, this approach can become even more profitable, strengthening their balance sheets. Hut 8 Mining is also frequently cited among significant miner holders.

Beyond Miners: Other Firms and New Entrants Embrace Bitcoin

Several non-mining public companies have also emerged as key Bitcoin holders, demonstrating diverse motivations. Block Inc. (formerly Square) holds around 8,038 BTC (worth ~$702M), reflecting its early entry and continued conviction in the asset. 

Tesla, despite selling a portion of its initial purchase in 2022, still maintains 11,509 BTC on its balance sheet. Coinbase, as a leading crypto-native exchange, naturally holds about 9,183 BTC for operational and reserve needs.

Additionally, newer entrants signal potentially broadening corporate adoption. Tokyo-based investment firm Metaplanet, for instance, has aggressively accumulated 2,888 BTC, drawing some comparisons to Strategy Inc.’s approach.

Video platform Rumble Inc. also made headlines by purchasing 188 BTC as part of its stated digital transformation strategy. This growing wave of diverse corporate interest suggests Bitcoin is becoming increasingly embedded within modern corporate finance considerations.
