Metaplanet Launches Securities Subsidiary After Siiibo Acquisition

• Metaplanet launches a licensed securities subsidiary to develop Bitcoin-linked financial products in Japan.
• Siiibo acquisition strengthens Metaplanet’s ability to structure regulated digital asset investments.
• Project Nova explores Bitcoin-backed credit products using blockchain and stablecoin infrastructure.

Metaplanet has launched Metaplanet Securities after completing its acquisition of Siiibo Securities, expanding its Bitcoin-focused strategy into regulated financial services in Japan.

The newly established subsidiary will develop Bitcoin-backed financial products while operating under Japan’s securities regulatory framework. The move marks a shift from Bitcoin accumulation toward building investment solutions linked to digital assets.

Metaplanet Expands Into Regulated Bitcoin Financial Products

Metaplanet completed the acquisition of Siiibo Securities on July 13 after announcing the transaction in June. The company acquired the Tokyo-based securities platform for approximately ¥2.1 billion, strengthening its position within Japan’s financial sector.

Following the acquisition, Siiibo Securities has been rebranded as Metaplanet Securities. The subsidiary operates under a Type I Financial Instruments Business Operator license from Japan’s Financial Services Agency.

This regulatory approval allows Metaplanet Securities to structure and distribute securities products within Japan’s financial markets. Therefore, the company can explore Bitcoin-linked investment products while following established regulatory requirements.

Siiibo Securities previously supported more than 40 companies and facilitated over 100 bond issuances. These activities included private placement corporate bonds and venture debt financing for businesses seeking alternative funding options.

Metaplanet said the new securities arm will support its broader Project Nova initiative. The project aims to create Bitcoin-focused financial infrastructure by connecting digital assets with traditional investment markets.

The company is working with yen stablecoin issuer JPYC and blockchain infrastructure provider Progmat on a Bitcoin-backed digital credit ecosystem. The initiative focuses on using Bitcoin as collateral or credit enhancement for future financial products.

However, Metaplanet has not confirmed any specific product launches, yield structures, or distribution timelines. Any future offerings will require additional approvals and regulatory discussions.

Project Nova Builds on Metaplanet’s Bitcoin Treasury Strategy

Metaplanet’s securities expansion follows its aggressive Bitcoin accumulation strategy. The company has positioned Bitcoin as a productive financial asset rather than only a long-term treasury reserve.

Through Metaplanet Securities, the company plans to explore opportunities involving Bitcoin-backed bonds, structured credit products, and tokenized financial instruments. These products could provide regulated exposure to Bitcoin-related returns for Japanese investors.

Meanwhile, Metaplanet continues increasing its Bitcoin holdings. The company reported holding approximately 43,000 BTC after purchasing 2,823 BTC during the second quarter.

Additionally, Metaplanet has outlined plans to expand its holdings to 210,000 BTC by the end of 2027. The company believes its Bitcoin reserves could support future financial products under Japan’s regulated securities environment.

The launch of Metaplanet Securities represents a broader attempt to combine Bitcoin treasury management with traditional finance. As regulatory frameworks develop, the company is positioning itself as a bridge between digital assets and institutional investment markets.
