Tokyo-listed investment firm Metaplanet’s largest shareholder, U.S. investment adviser Capital Research and Management Company, has increased its voting stake to 10.63% from 9.32%, according to a July 21 disclosure. The adjustment became effective on July 13, crossing the 10% threshold that triggers additional regulatory review in Japan.
Capital Research, a prominent asset manager within the Capital Group, has been gradually raising its position in Metaplanet over recent quarters. The move reflects deepening institutional confidence in Metaplanet’s unconventional treasury strategy, which centers on holding Bitcoin as a primary reserve asset.
Metaplanet currently holds approximately 43,000 Bitcoin, valued at roughly $2.8 billion at current market prices. This makes it the world’s third-largest corporate holder of Bitcoin among publicly listed companies, behind MicroStrategy and Marathon Digital Holdings. Since 2023, the firm has used debt issuance and operational cash flows to systematically acquire Bitcoin, regularly disclosing transactions to the Tokyo Stock Exchange.
The stake increase by a major U.S. institutional investor signals cross-border acceptance of Bitcoin-centric corporate models. It also strengthens Metaplanet’s access to capital markets and may encourage other asset managers to consider similar strategies. The news comes amid a broader trend of traditional finance warming to digital assets as a legitimate treasury component.
