Metaplanet, the Tokyo-listed company that has become Asia’s largest public Bitcoin treasury holder, saw its stock jump over 12% after announcing plans to acquire a securities firm and launch Bitcoin-backed yield products targeting Japanese investors.
The company is buying Siiibo Securities for 2.1 billion yen, roughly $13 million. The deal is expected to close in July 2026 and will grant Metaplanet something it has been chasing: a Type I securities license in Japan.
From Bitcoin hoarder to Bitcoin bank
Metaplanet has spent the last couple of years doing what MicroStrategy made famous: buying Bitcoin and putting it on the balance sheet. As of April 2026, Metaplanet holds approximately 40,177 BTC, acquired at an average cost basis of around $97,593 per coin.
Under what the company calls “Project Nova,” Metaplanet is pivoting from pure treasury accumulation to regulated product distribution. The acquisition of Siiibo Securities, which will be rebranded as Metaplanet Securities, is the infrastructure needed to make that happen. A Type I securities license in Japan allows a firm to deal in a wide range of securities products, and getting one from scratch is notoriously difficult and time-consuming.
