Metaplanet Moves to Acquire Siiibo Securities

Metaplanet has confirmed an agreement to acquire 100% of Siiibo Securities, a licensed Type I securities firm in Japan. Siiibo is famous for its role in Japan’s online corporate bond market and will be renamed Metaplanet Securities after the deal closes.

Notably, the acquisition is expected to be completed in July. It is the company’s first major acquisition and marks the first clear step under its long-term strategy, Project Nova. Simon Gerovich said the move is aimed at building a Bitcoin-focused financial ecosystem in Japan.

By bringing Siiibo Securities into the group, Metaplanet gains a regulated platform that can support new financial products tied to Bitcoin. Siiibo’s Type I license is a key part of the deal.

It allows broader securities operations under Japan’s financial rules. That gives Metaplanet a compliant structure for issuing and distributing investment products.

The company also disclosed Japan’s household savings base of about $7.4 trillion held in cash, deposits, and low-yield products. Metaplanet believes this pool is beginning to shift as inflation slowly returns and investors search for higher returns.

With Siiibo Securities integrated, Metaplanet plans to develop and distribute Bitcoin-related yield products directly within Japan’s regulated market.

Metaplanet Shares Rise as Bitcoin Treasury Strategy Expands

Market reaction to the announcement showed mild strength in Metaplanet stock pricek. The company’s shares on the Tokyo exchange rose 3.57%, or ¥8, closing at ¥232 during the session.

Still, Intraday trading ranged from ¥226 to ¥240. That reflected active investor attention following the acquisition news. The stock has also moved far below its 52-week high of ¥1,930 but remains above its 52-week low of ¥220.

Market capitalization currently stands at about ¥297.26 billion, with average trading volume near 31.93 million shares. The recent volume reached about 15.21 million shares during the session.

The price movement comes as Metaplanet continues to expand its Bitcoin treasury strategy. The company holds 40,177 BTC on its balance sheet, making it one of the largest corporate Bitcoin holders in Asia. Investors are watching how the acquisition of Siiibo Securities may affect future revenue models.

The addition of a licensed brokerage arm could allow Metaplanet to move beyond holding Bitcoin into structured financial product offerings. The market response suggests cautious optimism, with the stock gaining modestly but still trading well below its yearly peak.

Project Nova Push and Bitcoin Yield Plans

Metaplanet described the acquisition as a core step in Project Nova, its long-term plan to build a Bitcoin-centered financial system in Japan. The goal is to combine regulated securities infrastructure with Bitcoin treasury exposure. Thus, it can create investment products that can be offered within Japan’s legal framework.

Metaplanet Securities, once formed, will serve as the main platform for this strategy. The company said its Bitcoin holdings of 40,177 BTC will support the design of yield-linked products. These products are expected to be distributed through Siiibo’s existing online corporate bond platform after integration.

Metaplanet believes this structure can attract Japanese investors who are currently holding large amounts of cash in low-yield accounts. The firm sees this as an opportunity to introduce Bitcoin-linked returns through regulated channels.

The strategy also reflects a broader shift in Metaplanet’s identity. The company is moving from a Bitcoin treasury holder into a financial services operator with exposure to both digital assets and securities markets.

It is important to state that, alongside the announcement, market commentary noted that the Coinbase Bitcoin premium remains negative.

This is a sign of softer U.S. exchange demand compared to offshore markets. This highlights mixed conditions in the broader Bitcoin market even as corporate adoption continues.

Metaplanet’s focus remains on long-term positioning rather than short-term price movement. The company is building a regulated system that integrates Bitcoin into financial products rather than treating it solely as a reserve asset.
