Tokyo-listed Metaplanet Inc. has revealed a dramatic acceleration in its corporate Bitcoin strategy, reporting a year-to-date BTC Yield of 568.2% for 2025 while boosting total holdings to 35,102 BTC.
The disclosure highlights the company’s aggressive accumulation approach, positioning it among the world’s largest publicly disclosed corporate holders of Bitcoin.
Metaplanet Buys More Bitcoin
The company acquired an additional 4,279 BTC in the fourth quarter of 2025, paying an average of ¥16.33 million ($104,642) per coin, according to CEO Simon Gerovich.
This brings the aggregate investment in Bitcoin to approximately ¥559.7 billion, with an average price of ¥15.95 million ($102,207) per BTC for the year.
Metaplanet’s Bitcoin accumulation is part of its officially designated Bitcoin Treasury Operations, a strategic business line launched in December 2024.
Purchases are executed through a combination of operating income, capital market activities, and Bitcoin-backed credit facilities. This reflects a sophisticated treasury strategy that integrates market timing, equity management, and corporate financing tools.
In Q4 alone, BTC Yield reached 11.9%, a steady contribution to the annual performance, following earlier quarters that posted yields of 95.6%, 129.4%, and 33.0%.
The company’s proprietary BTC Yield metric measures the change in Bitcoin holdings per fully diluted share, isolating the impact of dilution from new equity issuance. This provides investors with a framework to assess shareholder accretion from Bitcoin accumulation rather than direct profit.
BTC Gain and BTC ¥ Gain translate these holdings into quantitative metrics in BTC and Japanese yen. This offers insight into the hypothetical value growth driven purely by the treasury strategy.
Metaplanet Ranks 4th Globally as Corporate Bitcoin Adoption Gains Momentum Despite Market Volatility
Despite the headline yield, data from Bitcoin Treasuries shows that Metaplanet’s portfolio is down 18.9% in market value terms. This reflects Bitcoin’s price volatility over the year.
The company emphasizes that BTC Yield is a KPI rather than a measure of realized gains or operational performance. It provides a lens into strategic accumulation rather than traditional financial returns.
Metaplanet now ranks as the fourth largest corporate Bitcoin holder globally, following Strategy (672,497 BTC), MARA (53,250 BTC), and Twenty One Capital (43,514 BTC).
Its approach, which blends disciplined accumulation, capital market activity, and leveraged facilities, highlights a trend among Japanese and global corporates to adopt Bitcoin as a treasury asset, balancing risk with strategic positioning for potential upside.
The announcement reinforces the growing role of corporate treasuries in Bitcoin markets, where companies like Metaplanet are quietly amassing significant positions while using metrics like BTC Yield to communicate strategy and performance to shareholders.
However, while headline yields are impressive, investors should differentiate between proprietary performance metrics and realized financial gains. This distinction is increasingly critical as institutional participation in Bitcoin scales globally.
With 35,102 BTC under management and a record BTC Yield, Metaplanet’s quiet accumulation strategy in 2025 positions it as a notable force in corporate Bitcoin adoption. It signals that publicly listed companies are increasingly using crypto as a strategic treasury tool rather than a speculative asset.
