Metaplanet raised its Bitcoin reserves to 18,113 BTC with its August 2025 purchase. The company uses equity and bond issuances to finance its aggressive buying strategy. It remains the sixth largest publicly traded Bitcoin holding company.
Metaplanet Inc. bought 518 more Bitcoin in August 2025, increasing its total reserve to 18,113 BTC and bringing its total investment close to $1.85 billion. Listed on the Tokyo Stock Exchange, the company’s accelerating treasury strategy positions it among the world’s significant public Bitcoin holders.
Since adopting Bitcoin as its core business line in December 2024, Metaplanet has aggressively expanded both its assets and goals. Recent regulatory filings and financial presentations demonstrate rapid acquisitions, new performance metrics, and a dynamic approach to capital markets financing.
Metaplanet Acquires Additional BTC
In August 2025, Metaplanet made a significant move by purchasing 518 Bitcoin for approximately 9.1 billion yen. This latest step brought its total holdings to 18,113 BTC. According to official statements, the company is now among the leading institutional Bitcoin treasury holders worldwide. The total purchase cost amounted to 270.364 billion yen ($1.85 billion), with an average price of about 14.9 million yen ($100,000) per Bitcoin.
Metaplanet’s announcement also introduced performance tracking innovations. Instead of focusing only on traditional metrics, the company uses a unique KPI called “BTC Yield,” which measures the ratio of total Bitcoin assets to fully diluted shares over time. According to filings, BTC Yield rose to 309.8% in Q4 2024, registered at 129.4% in Q2 2025, and recorded 26.5% between July and August 2025.

“BTC Yield reflects the percentage change in the ratio of Total Bitcoin Assets to Fully Diluted Shares during a specific period. The company uses BTC Yield to evaluate the performance of its Bitcoin purchase strategy aimed at benefiting shareholders,” Metaplanet stated.
This method reflects Metaplanet’s intensifying focus—since December 2024, Bitcoin treasury operations have become a central business activity, and the pace of acquisitions has accelerated.
Metaplanet Maintains 6th Place Ranking
Metaplanet finances its multi-billion yen Bitcoin purchases primarily through capital markets. The company raises cash by issuing shares and bonds; this strategy is detailed in financial reports and benchmark equity research. Official presentations show Metaplanet’s journey from zero Bitcoin at the start of 2024 to 1,762 by fiscal year-end.
Equity research also tracks the rise from 141 BTC in mid-2024 to 12,345 in June 2025 and 18,113 in August. The report details ambitious goals such as reaching 100,000 BTC by the end of 2025. Public disclosures emphasize clear, goal-oriented messaging.
Following the recent purchase, Metaplanet still holds the sixth largest public Bitcoin reserve. The company trails closely behind Trump Media & Technology Group Corp for fifth place. Strategy (formerly MicroStrategy) leads with 628,946 BTC, valued at around $74 billion at current market prices. On Monday, Michael Saylor announced an additional purchase of 155 BTC worth about $18 million.
