Capital Research and Management Company — a key subsidiary of Capital Group, one of the world's largest traditional asset managers with roughly $3.3 trillion in AUM — filed a disclosure with Japanese regulators today revealing it now holds 136,059,120 common shares of Metaplanet Inc. (TSE: 3350), equivalent to 10.63% of voting rights.
The stake was increased from a previously reported 9.32% by adding approximately 17.4 million shares, with the change effective as of July 13, 2026. The position is worth roughly $203 million at current prices.
Metaplanet has aggressively pursued a Bitcoin-first treasury policy since 2024, raising capital through equity offerings and bonds specifically to purchase Bitcoin. The company currently holds 43,000 BTC valued near $2.9 billion at a BTC price of $66,200, making it the third-largest corporate Bitcoin holder globally behind Strategy (843,775 BTC) and Twenty One Capital (43,514 BTC).
What makes this notable is the investor: Capital Group is renowned for its long-term, fundamentals-driven approach through flagship funds like American Funds. This is not a crypto-native firm or a hedge fund making a speculative bet. It is one of the most conservative asset managers in the world choosing to become the largest shareholder of a leveraged Bitcoin holding company.
Capital Group already maintains a notable equity position in Strategy (MSTR). By adding Metaplanet, the firm now holds stakes in Bitcoin treasury companies across two jurisdictions — the United States and Japan.
The timing adds further weight. Metaplanet's stock has been down approximately 87% from its highs amid broader crypto market volatility and repeated equity dilution to fund Bitcoin purchases. Yet Capital Group chose to increase its position during this drawdown, suggesting the manager views current levels as attractive relative to the underlying Bitcoin holdings.
For traditional asset managers whose mandates limit direct crypto exposure, equity stakes in dedicated Bitcoin treasury companies offer a regulated, equity-market gateway. Capital Group's move signals validation of the corporate Bitcoin treasury model as an investable thesis — not just a single coin bet.
