Metaplanet Adds 2,823 Bitcoin, Reaches 43,000 BTC and Becomes World’s Third-Largest Corporate Treasury

Metaplanet crossed the 43,000 BTC threshold on July 2, a milestone that places the Tokyo-listed firm as the world’s third-largest corporate Bitcoin holder. The company now trails Strategy and Twenty One Capital across the global corporate ranking, and its climb underscores Japan’s role in the corporate Bitcoin accumulation race.

Metaplanet acquired an additional 2,823 BTC during the second quarter of 2026, a purchase worth about $170.7 million. The buy brought total holdings to 43,000 BTC, valued near $2.6 billion. Shares of the company (ticker 3350) closed 3.5% higher at 207 yen ($1.28) on Thursday following the announcement.

The average acquisition price for the quarter landed at roughly 12.71 million yen (about $80,000) per Bitcoin, according to the company. The effective purchase price fell to around 12.09 million yen (about $77,000) once income from the firm’s Bitcoin Income Generation business is counted. 

That segment produced approximately 1.75 billion yen ($10.85 million) in operating revenue for the quarter, lifting first-half revenue to about 4.72 billion yen. On a trailing 12-month basis, the division’s revenue reached about 11.4 billion yen.

Metaplanet’s total Bitcoin investment now stands at approximately 659.25 billion yen (about $4.2 billion), with holdings valued near 409 billion yen (about $2.6 billion) as of June 30. The overall average cost basis sits at 15.33 million yen (about $102,500) per BTC.

The company reported a BTC Yield of 6.6% for the quarter ended June 30, 2026, a metric that tracks growth in Bitcoin per share. That figure remains a core indicator for corporate treasury strategies of this type.

The corporate Bitcoin leaderboard is now well defined. Strategy, the former MicroStrategy, leads with holdings above 847,000 BTC. Twenty One Capital holds second place. Metaplanet takes third, a position that puts it ahead of other large players such as MARA Holdings, according to data tracked by Bitcoin Treasuries.

Michael Saylor marked the occasion on X, tweeting, “Congrats to Metaplanet on reaching ₿43,000 and becoming the #3 corporate Bitcoin treasury in the world. You are proving that the Bitcoin treasury strategy is global.”

The strategy behind Metaplanet

Metaplanet has scaled at speed since it adopted the treasury model in 2024. CEO Simon Gerovich has drawn on equity offerings, debt instruments, and options strategies to build the position, an approach designed to limit the shareholder dilution that comes with large corporate purchases. The Bitcoin Income Generation business uses Bitcoin options to create recurring cash flow while the company expands its holdings.

The balance sheet leaves room to grow. Total debt and preferred stock represent about 23% of the net asset value of the firm’s Bitcoin, a cushion that gives Metaplanet capacity to keep buying.

The dual model, one part aggressive accumulation and one part recurring income, cements Japan as a rising force in the corporate push to hold Bitcoin as a reserve asset.
