As of May 31, 2026, the company held **40,177 BTC**, making it the **largest corporate Bitcoin holder in Japan**, the **largest in Asia**, and the **third largest corporate holder globally**. Those holdings were valued at approximately **JPY 457.6 billion**, providing the company with a substantial [Bitcoin](https://coinlaw.io/bitcoin-statistics/) reserve that it now plans to use as a foundation for new financial products. Until now, Metaplanet’s growth story has largely focused on acquiring and holding Bitcoin. The Siiibo acquisition signals a broader ambition to monetize that position by developing investment products tied to its digital asset holdings. ## Why Siiibo Securities Matters? Siiibo Securities is a licensed **Type I Financial Instruments Business Operator** in Japan. The company is known for its online [corporate bond](https://coinlaw.io/corporate-bond-default-statistics/) platform and has supported more than **100 bond issuances for over 40 companies**. By bringing Siiibo into the group, Metaplanet gains access to important regulatory licenses, securities expertise, and an existing network of both retail and corporate investors. The acquisition provides the infrastructure needed to structure and distribute a range of investment products that could appeal to Japanese investors seeking alternatives to traditional low yield savings products. Following the completion of the transaction, Metaplanet also plans to appoint two directors to the securities firm’s board. ## Project Nova Takes Shape Metaplanet described the acquisition as the first major milestone in **Project Nova**, a long term strategy designed to create a Bitcoin-focused financial services ecosystem. Future offerings could include: - **Bitcoin linked bonds** - **Bitcoin related yield products** - **Digital securities** - **Security tokens** - **Tokenized financial instruments** - **Bitcoin-backed investment products** Commenting on the deal, Metaplanet CEO **Simon Gerovich** said: “ We view Bitcoin not merely as a treasury reserve asset, but as the foundation of the next generation of financial ecosystems. Simon GerovichCEO – Metaplanet Gerovich also highlighted the opportunity within Japan’s financial market, noting that Japanese households hold roughly **$7.4 trillion** in cash, deposits, and other low yield products. In a post on X, he stated: “ By bringing Siiibo’s Type I registration and online securities platform into the group, we will develop and distribute Bitcoin-related yield products directly to Japanese investors, supported by the 40,177 BTC on our balance sheet, the largest corporate Bitcoin treasury in Asia. Simon GerovichCEO – Metaplanet ## Funding and Market Reaction Metaplanet said the acquisition will primarily be funded through cash reserves and borrowings. The company may also utilize its [Bitcoin backed credit facilities](https://coinlaw.io/metaplanet-bitcoin-loan-expansion-130m/), which provide borrowing capacity of up to **$500 million**. Investors initially reacted positively to the announcement, with Metaplanet shares rising more than **3.6%** following the news. However, the stock remains heavily influenced by Bitcoin’s price movements and has experienced significant volatility in recent months. ![Metaplanet Stock Price 12th June](https://coinlaw.io/wp-content/uploads/2026/06/metaplanet-stock-price-12th-june.png)Image Credit – [Google Finance](https://www.google.com/finance/quote/3350:TYO?sa=X&ved=2ahUKEwiX0o-GwYGVAxVlRmwGHUuzI9sQ3ecFKAN6BAgpEAQ) ## CoinLaw’s Takeaway In my experience, this deal is much more important than a standard acquisition. Many companies have built large **Bitcoin treasuries**, but very few are taking meaningful steps toward creating financial products around those holdings. I found Metaplanet’s strategy particularly interesting because it is moving from simply holding Bitcoin to building an entire investment ecosystem around it. If **Project Nova** succeeds, Metaplanet could become one of the first publicly listed companies to directly connect a massive corporate Bitcoin treasury with regulated investment products for everyday investors. That could create a new model for how companies use Bitcoin as more than just a balance sheet asset.
