Japanese investment company Metaplanet has strengthened its position among corporate Bitcoin holders, acquiring an additional 5,268 BTC worth roughly $600 million. The move, announced Wednesday, lifts its total Bitcoin holdings to 30,823 BTC, valued at about $3.6 billion at current market prices.
Metaplanet climbs to fourth place among corporate Bitcoin holders
The latest acquisition places Metaplanet ahead of the Bitcoin Standard Treasury Company, securing the fourth spot globally among corporate Bitcoin holders. According to data from BitcoinTreasuries.NET, the purchase was executed at an average price of 17.39 million yen ($116,000) per BTC.
Metaplanet’s aggressive accumulation strategy has already delivered results. The company now enjoys an unrealized profit of more than 7.5%, reflecting Bitcoin’s steady rise through 2025.
“This development underscores how corporates are adopting Bitcoin not just as a hedge, but as a core treasury asset,” said Naoki Takahashi, Head of Digital Strategy at Tokyo-based investment firm SBI Holdings, in a statement to Nikkei Asia.

Metaplanet’s rapid expansion and Bitcoin yield
Metaplanet began adding Bitcoin to its balance sheet in April 2024 and has since grown faster than nearly every other corporate buyer. By late 2024, its BTC Yield which tracks the percentage change in Bitcoin holdings relative to its fully diluted shares had soared to 309.8% before stabilizing at 33% in 2025.
A yield above 300% meant each Metaplanet share provided more than three times the Bitcoin exposure it did at the start of its strategy. While the pace of accumulation slowed this year, the company remains one of the most aggressive among corporate Bitcoin holders.
“Metaplanet’s Bitcoin play highlights the changing nature of corporate finance,” said Daniel Batten, managing partner at CH4 Capital. “Its BTC Yield shows how firms can significantly enhance shareholder exposure to Bitcoin while managing equity dilution.”

Corporate Bitcoin holders now control 1 million BTC
The rise of Metaplanet reflects a broader trend: public companies now hold over 1 million BTC, according to BitcoinTreasuries.NET. This equates to about 4.7% of Bitcoin’s capped supply, valued at $116 billion.
Beyond corporates, Bitcoin in treasuries spanning exchange-traded funds (ETFs), government reserves, exchanges, and private companies has climbed to 3.8 million BTC, or nearly $442 billion.
Other assets are also entering treasury portfolios. Data from the Strategic ETH Reserve shows that Ether-based treasuries now hold 12.14 million ETH, valued at $52 billion. Meanwhile, the Strategic SOL Reserve reports that Solana treasuries reached 20.92 million SOL, worth around $4.55 billion.
For investors, the growing participation of corporate Bitcoin holders is reshaping perceptions of digital assets from speculative plays to institutional-grade reserves.
Implications for crypto investors and policymakers
Metaplanet’s rise among corporate Bitcoin holders signals that Bitcoin is no longer confined to balance sheets of U.S. firms like MicroStrategy or Tesla. Japanese corporates, historically cautious in adopting risk assets, are now embracing Bitcoin as a long-term store of value.
This is not just about portfolio diversification; it’s about future-proofing against monetary instability, said Kenji Yamamoto, a blockchain policy researcher at the University of Tokyo.
For policymakers, the trend poses both opportunities and challenges. As more corporate Bitcoin holders emerge, governments must weigh potential risks to financial stability against the innovation benefits of blockchain adoption.
In Japan, regulators have so far supported innovation while maintaining strict compliance oversight, a balance that may attract more firms to follow Metaplanet’s lead.
What’s next for Metaplanet and corporate Bitcoin holders
Looking ahead, Metaplanet’s aggressive stance could encourage more Asian firms to adopt Bitcoin as part of their treasuries. With public companies already controlling nearly 5% of total supply, the growing influence of corporate Bitcoin holders raises questions about scarcity, liquidity, and market concentration.
For crypto investors, Metaplanet’s $600 million purchase reinforces Bitcoin’s role as a strategic corporate reserve asset. As the market continues to mature, analysts expect more firms to disclose large-scale Bitcoin holdings, further legitimizing the asset in global finance.
As Batten of CH4 Capital put it: “The rise of corporate Bitcoin holders is one of the strongest signals yet that Bitcoin has transitioned from the margins of finance to its core.”
