What Happened?
Japanese Bitcoin treasury company Metaplanet has agreed to acquire Siiibo Securities, a Tokyo-based licensed securities firm, in a transaction valued at approximately JPY 2.1 billion ($13.1 million). The acquisition is expected to close on July 13, 2026, after which Siiibo Securities will be renamed Metaplanet Securities.

Metaplanet Moves Beyond Bitcoin Treasury Holdings
Metaplanet has become one of the world’s most closely watched corporate Bitcoin holders after adopting a Bitcoin treasury strategy similar to that of Strategy. 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 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 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:
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:
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, 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.
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.
