Metaplanet Inc. has expanded its Bitcoin reserves to 18,113 BTC as of August 12, 2025, following the purchase of an additional 518 BTC at an average price of ¥17.54 million per coin, bringing the company’s total investment to ¥270.36 billion.
The Tokyo-based firm has been executing an aggressive Bitcoin accumulation strategy since making Bitcoin Treasury Operations an official business line in December 2024, using capital market activities and operating income to fund acquisitions.
The company’s BTC Yield, a key performance indicator measuring the percentage change in Bitcoin per fully diluted share, has surged across consecutive quarters, recording 309.8% in Q4 2024, 95.6% in Q1 2025, 129.4% in Q2 2025, and 26.5% so far in Q3 2025. From July 1 to August 12, the company’s BTC Gain reached 3,549 BTC, equivalent to ¥63.19 billion at a reference price of ¥17.8 million per Bitcoin.
Metaplanet’s acquisitions have been supported by significant capital markets activity, including the early redemption of ¥12.75 billion from its 19th Series Ordinary Bonds in July, funded by proceeds from the exercise of stock acquisition rights. During the same period, the company issued over 39 million shares in multiple tranches, including 9 million each on July 10 and July 14.
