Capital Group's Bitcoin Bet Soars: $1B to $6B in Four Years

Led by seasoned portfolio manager Mark Casey, Capital Group's aggressive Bitcoin investment approach has converted a $1 billion gamble into more than $6 billion in only four years, challenging the conservative foundation of the business. After meeting advocate Wences Casares in 2013, inspired by value investing giants such as Benjamin Graham and Warren Buffett, Casey adopted Bitcoin as a commodity equivalent to gold. Rather than direct crypto investments, his strategy emphasizes "Bitcoin treasury businesses"—public corporations with Bitcoin on their balance sheets.

Initially purchased for more than $500 million in 2021, Capital Group's strategy now has a 7.89% share in Strategy (previously MicroStrategy), valued around $6.2 billion following a 2,200% stock increase over five years. With a 5% stake in Japan's Metaplanet, a hotel operator turned Bitcoin accumulator, and shares in mining corporation MARA Holdings, the company also diversified. Using this varied strategy, public companies are used to acquire Bitcoin exposure, therefore fitting with a general tendency whereby public companies possess over 1 million BTC worth. As of August 2025, more than $117 billion.

Though corporate Bitcoin hoarding slowed in August 2025, with 47,718 BTC added against July's over 100,000 BTC, overall institutional holdings reached 3.68 million BTC, valued about $400 billion. The success of Capital Group as a $3 trillion asset manager points toward a change in conventional investing, fusing emerging digital assets with rigorous value criteria. This success might motivate other institutional investors to investigate Bitcoin exposure via publicly listed surrogate companies, therefore transforming the investment scene.
