Corporate bitcoin accumulation reached unprecedented levels in June 2025, with Relab Labs' latest data showing the top ten corporate bitcoin holders collectively owning 445,175 bitcoins, representing 2.12% of the total supply. MicroStrategy leads the list with 205,000 bitcoins worth over $12.5 billion, after purchasing an additional 1,045 bitcoins for $66.5 million at an average price of $63,636 in early June 2025. The Enterprise Software-maker had already announced a $1.3 billion debt offering in mid-May to finance further bitcoin purchases, clearly indicating the company's ongoing accumulation strategy.
The corporate bitcoin accumulation trend is also strengthening in Europe, where Relai, one of Switzerland's largest bitcoin brokers, established Europe's first bitcoin treasury company, Bitcoin Reserve Ltd, in May 2025 with an initial investment of €50 million, planning to increase this to €340 million for further bitcoin purchases. BlackRock's bitcoin ETF is also breaking records, with total assets under management for all bitcoin-holding ETFs reaching $59.62 billion, indicating that traditional financial institutions are increasingly investing in the cryptocurrency. Marathon Digital Holdings has accelerated its accumulation strategy, amassing 17,545 bitcoins worth nearly $1.1 billion by the end of May 2025, while Coinbase holds 25,000 bitcoins on its balance sheet, valued at approximately $1.5 billion.
The corporate bitcoin accumulation trend continued alongside a significant rise in bitcoin's price, which climbed from $70,000 on June 7, 2025, to above $73,000 by June 10, representing a 4.3% increase. This trend is driven by factors such as seeking inflation protection, diversification strategies, and clarification of crypto market regulations, particularly in the US where the SEC approved spot bitcoin ETFs in early 2024. The growth in corporate bitcoin ownership signals long-term confidence in the digital asset as the market becomes more mature and stable, expected to attract more institutional investors in the future.
