Metaplanet disclosed that it has agreed to acquire Japanese securities firm Siiibo Securities for 2.1 billion yen. Following the completion of the transaction, the firm will be renamed Metaplanet Securities. This deal demonstrates that the company, known for its Bitcoin treasury strategy, is expanding into the issuance and distribution of Bitcoin-related financial products.
Access a licensed Japanese securities platform
The core of this acquisition lies in Metaplanet gaining direct control of a Japanese Type I Financial Instruments Business operator. This license enables the design, underwriting, and distribution of securities products, and provides the company with an established compliance platform to launch Bitcoin-linked products for Japanese investors.
The company refers to this transaction as the first major acquisition under the Project Nova financial ecosystem initiative. Metaplanet stated that it will develop income-generating products and other investment tools centered around its Bitcoin assets in the future.
40,177 BTC serve as the underlying asset.
As of May 31, 2026, Metaplanet holds 40,177 BTC. The company states that this is the largest corporate Bitcoin holding in Japan and the third-largest globally. According to the company’s disclosed figures, the net value of these assets is approximately ¥457.6 billion.
Management stated that the company no longer views Bitcoin solely as a reserve asset on its balance sheet, but aims to transform this holding into a foundation for financial products. Potential future directions may include BTC-linked bonds, digital securities, security tokens, and other Bitcoin-related investment products.
Connect to the bond platform and existing investor network
Siiibo's existing business includes an online corporate bond platform, as well as private placement bond and venture debt financing services for enterprises. According to the information provided, the company has served over 40 enterprises and supported more than 100 bond issuances. Following its acquisition by Metaplanet, Metaplanet will also inherit Siiibo’s existing investor network.
The company stated that Siiibo holds the necessary licenses to distribute financial products, along with a base of retail and institutional investors. This means Metaplanet has not only obtained the required licenses but also gained immediate access to an established sales channel.
