Bitcoin Treasury Growth Accelerates

The company has been scaling up its Bitcoin Treasury Operations since making Bitcoin an official business line in December 2024. In just five months, Metaplanet’s holdings surged from 4,046 BTC in March 2025 to 20,000 BTC by September.

Quarterly performance metrics show robust returns on this strategy. The firm reported a BTC Yield of 309.8% in Q4 2024, followed by 95.6% in Q1 2025, 129.4% in Q2 2025, and 30.7% for Q3-to-date. BTC Yield measures the ratio of Bitcoin per fully diluted share, designed to show accretive growth despite dilution from share issuances.

During Q2, the company’s Bitcoin per fully diluted share rose to 0.016 BTC per 1,000 shares, before increasing again to 0.021 BTC in Q3, signaling consistent shareholder exposure growth to Bitcoin despite capital market activities.

Capital Markets and Strategic Positioning

Metaplanet funded much of its expansion through equity issuance and bond redemptions. In July and August 2025, the company redeemed over ¥20 billion in bonds, which was financed through the exercise of stock acquisition rights. This enabled sustained purchases, pushing weekly Bitcoin buys as high as 1,500 BTC in August. As of September, Metaplanet’s 20,000 BTC stash places it among the largest publicly listed Bitcoin holders globally, underscoring Japan’s growing presence in institutional Bitcoin adoption.

Meanwhile, the organization strengthened its Bitcoin treasury strategy with the acquisition of an additional 103 BTC, valued at ¥1.736 billion. The purchase was made at an average price of ¥16.85 million per Bitcoin, raising the company’s total holdings to 18,991 BTC.
