Public companies investing in Bitcoin as treasury assets was once considered laughable. The leading cryptocurrency was deemed too volatile and niche for serious institutional adoption. Yet this taboo has been decisively shattered, with major corporations now aggressively accumulating BTC.
According to BitcoinTreasuries, publicly traded companies currently hold 2.8% of Bitcoin's total 21 million BTC supply. Below are the largest corporate holders as of 2025:
1. MicroStrategy (Formerly Strategy)
Holdings: 461,000 BTC (~$48 billion)
Industry: Business Intelligence → Bitcoin Treasury
The Virginia-based tech firm pioneered corporate Bitcoin adoption in August 2020 under CEO Michael Saylor, who famously claims to buy "$1,000 of BTC every second." Their BTC reserves now exceed 2% of Bitcoin's total supply.
