Metaplanet buys Siiibo Securities to accelerate bitcoin financial ecosystem plans

Metaplanet (3350) acquired Siiibo Securities, a Tokyo-based Type I Financial Instruments Business Operator, in a deal valued at approximately 2.1 billion yen ($13.1 million), the Japanese bitcoin treasury company announced on Friday.

Following the completion of the transaction, Siiibo Securities will become a wholly owned subsidiary, renamed Metaplanet Securities.

The acquisition marks the first major step in Metaplanet’s “Project Nova,” a long-term strategy aimed at building a bitcoin-focused financial ecosystem. The company, which holds 40,177 BTC ($2.6 billion) as of May 31, views bitcoin not only as a treasury asset but also as the foundation for a new generation of financial products and services.

Siiibo Securities specializes in corporate bond issuance and distribution through an online platform and has supported more than 100 bond offerings for over 40 companies. Metaplanet believes the firm’s regulatory licenses, customer base, and securities expertise complement its ambitions in digital assets and tokenized finance.

The companies expect synergies including the development of bitcoin-linked investment products, expanded securities distribution capabilities, and the creation of tokenized financial instruments. Metaplanet also plans to leverage Siiibo’s platform to provide new yield-generating opportunities for investors and strengthen its presence in Japan’s evolving digital asset market.
