Metaplanet is acquiring Siiibo Securities for $13 million to launch Bitcoin-linked financial products and expand its crypto-focused financial ecosystem in Japan.
Metaplanet has agreed to acquire Siiibo Securities for 2.1 billion yen ($13 million), giving the Japanese Bitcoin (BTC) treasury company a licensed securities platform to develop and distribute Bitcoin-linked yield products to retail investors in Japan.
Metaplanet CEO Simon Gerovich announced the deal on X on June 12. The transaction is expected to close in July 2026. Metaplanet plans to rebrand Siiibo Securities as Metaplanet Securities following the close.

Siiibo Securities holds a Type I financial instruments business license in Japan. It operates an online platform that allows retail investors to participate in privately placed corporate bonds, a market that has historically been accessible only to institutions and high-net-worth individuals. Since its founding in 2019, Siiibo has facilitated more than 100 bond issuances for over 40 companies.
Bitcoin-Centric Financial Ecosystem Takes Shape
Gerovich described the acquisition as the first concrete step in "Project Nova," Metaplanet's long-term strategy to build a Bitcoin-focused financial ecosystem in Japan. He said integrating Siiibo's Type I registration and online securities platform into the group would allow Metaplanet to move beyond $BTC accumulation and into investor-facing financial products. The company currently holds 40,177 BTC, which Gerovich said would support the new business.
Japanese households held 1,140 trillion yen ($7.1 trillion) in cash and deposits at the end of 2025, representing approximately 48.5% of their total financial assets, according to data published by the Bank of Japan in March 2026. Gerovich said that as Japan transitions from deflation to inflation, that capital has "begun searching for yield."
"Our mission is to deliver new yield-generating opportunities through a bitcoin-centric financial platform, and to build, from Japan, a financial ecosystem that unites bitcoin with traditional finance," Gerovich said in a separate statement.
Metaplanet and Siiibo Post Net Losses Ahead of Deal
Siiibo posted a net loss of 175.4 million yen ($1.1 million) in 2025, up from a net loss of 162.1 million yen ($1 million) in 2024. Metaplanet recorded a net loss of 114.5 billion yen ($715.4 million) in Q1 2026, driven by mark-to-market valuation losses on its Bitcoin holdings at the end of the period.
Metaplanet's Tokyo-listed shares closed up 3.6% on June 12. The stock remained down approximately 31.7% over the prior 30 days. The company's move into securities distribution marks its first major corporate acquisition and its first step toward building a regulated DeFi-adjacent financial infrastructure in Japan.
