TOKYO, June 12, 2026 – Metaplanet has announced its first major acquisition, agreeing to purchase 100% of Siiibo Securities as part of its plan to expand Bitcoin-focused financial services in Japan. The deal is expected to close in July, after which the company will operate under the new name Metaplanet Securities.
The acquisition marks an important step in Metaplanet’s long-term growth strategy and highlights its ambition to move beyond simply holding Bitcoin on its balance sheet.
Metaplanet Advances Project Nova Strategy
The transaction supports Metaplanet’s broader “Project Nova” initiative, which aims to build a complete Bitcoin-centered financial ecosystem. By acquiring Siiibo Securities, the company gains access to a licensed securities platform and a direct entry point into Japan’s regulated financial market.
Instead of spending years building a securities business from the ground up, Metaplanet can immediately leverage Siiibo’s existing infrastructure, regulatory approvals, and customer network.
Key benefits of the acquisition include:
- Access to Japan’s regulated securities market
- Existing financial licenses and operational infrastructure
- Connections with retail and corporate investors
- Faster development of Bitcoin-related investment products
New Bitcoin Investment Products Could Follow
Siiibo Securities has earned recognition for its online marketplace focused on corporate bond issuance and investment opportunities. The platform helped expand access to fixed-income products for individual investors across Japan.
Following the acquisition, Metaplanet may introduce new Bitcoin-linked financial offerings. Management has suggested potential products could include:
- Bitcoin yield-generating instruments
- Digital securities tied to BTC
- Bitcoin-backed bond products
These offerings could attract investors seeking alternative income opportunities connected to digital assets.
Growing Beyond a Bitcoin Treasury Company
Metaplanet currently holds more than 40,000 BTC, making it one of the largest corporate Bitcoin holders in the world. However, the company now appears focused on creating financial infrastructure around those holdings.
Industry analysts believe this move represents the next stage of the corporate Bitcoin treasury model. If successful, Metaplanet could emerge as a leading provider of regulated Bitcoin investment products in Japan while setting an example for companies exploring digital asset integration within traditional finance.
