Woofun AI reports that Metaplanet, a Tokyo-listed investment firm, disclosed on July 21 that its largest shareholder, U.S. investment adviser Capital Research and Management Company, has increased its voting stake to 10.63%. This adjustment, which took effect on July 13, reflects continued confidence from a major institutional investor in the company’s aggressive Bitcoin accumulation strategy. The move underscores a growing alignment between traditional asset managers and corporate entities adopting digital assets as primary treasury reserves.

The stake increase from 9.32% to 10.63% represents a 1.31 percentage point gain, crossing the 10% threshold that often triggers additional regulatory scrutiny and disclosure requirements in Japanese markets. Capital Research, a well-established asset manager overseeing hundreds of billions in global assets, has steadily raised its position in Metaplanet over recent quarters. This incremental buildup suggests a calculated, long-term commitment rather than a speculative short-term trade. The crossing of the 10% mark is particularly significant, as it mandates greater transparency and indicates a level of conviction that exceeds passive indexing or minor tactical allocations.

Metaplanet currently holds approximately 43,000 Bitcoin, valued at roughly $2.8 billion based on current market prices. This positions the company as the world’s third-largest corporate holder of Bitcoin among publicly listed firms, trailing only MicroStrategy and Marathon Digital Holdings. The sheer scale of these holdings distinguishes Metaplanet from smaller competitors and places it at the forefront of the corporate Bitcoin adoption narrative. By maintaining such a substantial reserve, the firm demonstrates a clear strategic preference for digital assets over traditional cash or bond holdings, a stance that continues to draw attention from global financial observers.

The company’s strategy, which began in earnest in 2023, involves using debt issuance and operational cash flows to acquire Bitcoin as a primary treasury reserve asset. This approach has been executed with a degree of transparency, with the firm regularly disclosing acquisition details to the Tokyo Stock Exchange. Such openness has helped attract both retail and institutional investors seeking indirect exposure to Bitcoin’s price movements without directly holding the cryptocurrency. The mechanics of this strategy—leveraging debt to buy a non-yielding asset—remain controversial in traditional finance, yet Metaplanet’s consistent execution has provided a real-world case study for other corporations considering similar moves.

Woofun AI data shows that the stake increase by Capital Research carries weight beyond a single company, reflecting a broader trend of traditional institutional investors gaining comfort with Bitcoin-focused corporate strategies. When a major U.S. investment adviser increases its position in a Japan-listed Bitcoin treasury company, it signals cross-border confidence in both the asset class and the corporate model. For Metaplanet, the strengthened backing from a top-tier institutional investor could improve its access to capital markets and reduce perceived risk among other potential shareholders. This validation adds credibility to the argument that Bitcoin can serve as a legitimate corporate treasury asset, a thesis that remains debated in mainstream finance but is gaining traction among forward-looking asset allocators.

Capital Research’s increased voting stake in Metaplanet underscores growing institutional acceptance of Bitcoin-centric corporate strategies. With 43,000 BTC on its balance sheet, Metaplanet continues to carve a unique position in global equity markets, challenging conventional wisdom about corporate treasury management. Investors will watch closely to see whether this trend prompts other major asset managers to follow suit, potentially accelerating the integration of digital assets into the broader financial system. This marks a significant step toward the normalization of Bitcoin as a standard component of diversified corporate portfolios.
