Metaplanet Secures Historic Financial Deal

According to the announcement, the investment giant will shell out 21 billion yen to acquire all the outstanding shares of the boutique brokerage firm. 

Hence, this transaction is the first significant corporate acquisition in the history of the Bitcoin-focused treasury pioneer. 

The high-profile transaction is targeted to close by the end of July 2026, which is the deadline set by regulators.

Post-closure, the firm will immediately revise the licensed financial firm to Metaplanet Securities. 

Moreover, this newly acquired company will be the first consolidated subsidiary of this main enterprise. 

In a tweet on X, Metaplanet CEO Simon Gerovich said that the business had reached a deal to acquire all shares of Siiibo Securities Co., Ltd. 

For reference, the company is a Type I Financial Instruments Business Operator. 

It also features an online platform that allows private investors to offer corporate bonds.

Project Nova Drives Metaplanet Strategy

The historic acquisition officially launches an ambitious internal initiative known globally within the sector as “Project Nova.” 

Through this plan, Metaplanet aims to build a comprehensive, Bitcoin-centric financial ecosystem across Asia. 

The visionary company plans to integrate its legacy securities system with sovereign digital-asset treasuries.

The merged group will develop new income-producing financial products directly for Japanese institutional and retail investors, linked to Bitcoin.

Management will tap into its huge corporate treasury of 40,177 BTC to support these innovative products. 

As such, domestic investors will have one-of-a-kind access to institutional-grade digital asset yields in a fully regulated environment.

This is an additional alternative to foreign spot exchange-traded funds. 

Local institutions have frequently requested regulated access to sovereign digital capital.

Therefore, Project Nova meets this demand for corporations with an optimized native platform.

Capital Financing for the Siiibo Deal

The firm will fund this historic 21 billion yen transaction using cash reserves and strategic debt. 

Alternatively, corporate leadership is exploring Bitcoin-collateralized institutional loans worth up to $500 million. 

It is an innovative form of debt that allows the Company to use its large number of tokens without selling off its spot assets.

In the interim, management said the final purchase won’t affect its short-term financial reporting. 

Specifically, the effect of this acquisition on the fiscal year 2026 is still completely negligible.

The long-term view, however, provides a strong base for institutionalized digital asset banking in Japan.

Overall, this strategic acquisition solidifies the firm’s position as a leading institutional digital asset firm. 

It is believed this model will be emulated by other public corporations in Asia.
