The deal is expected to close in July, and will give Metaplanet access to a Type I securities license and an online investment platform that it plans to use for Bitcoin-linked yield products. The acquisition supports the company's strategy to expand beyond Bitcoin accumulation and offer investment products backed by its treasury holdings.
Metaplanet Buys Siiibo Securities
Japanese Bitcoin treasury firm Metaplanet is expanding, and announced plans to acquire Siiibo Securities for 2.1 billion yen, which is approximately $13 million.
According to Metaplanet Chief Executive Officer Simon Gerovich, the company agreed to acquire 100% of Siiibo Securities, a licensed Type I securities firm that established itself as a major player in Japan’s online corporate bond market. The transaction is expected to be completed in July, after which the company plans to rename the business Metaplanet Securities.
The acquisition is the first major corporate purchase under Metaplanet’s long-term initiative known as Project Nova. Gerovich described the move as the first concrete step toward building a comprehensive bitcoin-centric financial platform capable of serving investors directly.
While Metaplanet is known for its aggressive Bitcoin accumulation strategy, the company now seems focused on expanding its business model into financial products and services that leverage its growing Bitcoin reserves.
Gerovich explained that bringing Siiibo Securities into the Metaplanet group will provide access to a valuable securities license and an established online investment platform. This infrastructure will allow the company to create and distribute Bitcoin-related yield products directly to Japanese investors. The strategy will be supported by Metaplanet’s Bitcoin holdings, which currently stand at more than 40,000 BTC.

The company believes the timing is favorable due to changing economic conditions in Japan. For decades, Japanese households have traditionally favored holding cash and bank deposits over higher-risk investments. Data from the Bank of Japan shows that households held approximately 1,140 trillion yen, or around $7.1 trillion, in cash and deposits at the end of 2025, which is nearly half of all household financial assets in the country.
However, Japan’s shift from a long period of deflation toward a more inflationary environment is encouraging investors to look for better returns on their savings. Metaplanet sees this trend as an opportunity to introduce alternative investment products that combine the potential benefits of Bitcoin with more traditional financial structures.
Siiibo Securities operates as an independent Type I financial instruments business operator. The company specializes in providing retail investors with access to privately placed corporate bonds, which is a market that has historically been dominated by institutional investors and wealthy people.
