Metaplanet has ascended to become the world's third-largest corporate bitcoin holder after adding 5,075 BTC to its treasury in Q1 2026 for $398 million. The Japanese company's aggressive accumulation strategy allowed it to overtake MARA Holdings, which recently executed a $1.1 billion bitcoin sell-off that dropped it from the top corporate holder rankings.
The $398 million bitcoin purchase represents a significant capital deployment by Metaplanet, demonstrating the company's commitment to building a substantial cryptocurrency treasury. MARA Holdings' decision to liquidate $1.1 billion worth of bitcoin created an opening in the corporate bitcoin holder rankings that Metaplanet quickly filled.
