Metaplanet To Acquire Japanese Securities Platform Siiibo for $13mn

It's Metaplanet's first major acquisition for Project Nova, the company’s long-term plan to build a Bitcoin-centric financial ecosystem in Japan.

"With 40,177 BTC on our balance sheet, the largest corporate treasury in Asia, we intend to meet demand [for yield] with regulated, Bitcoin-backed yield products," Metaplanet CEO Simon Gerovich told Sandmark. "Buying a licensed platform compresses years of build time into a single transaction, and it is the first concrete step in that direction."

Siiibo will be renamed Metaplanet Securities after the transaction closes, expected on 13 Jul.

Licence provides distribution channel

Metaplanet said the acquisition price reflects the cost and time required to obtain a Type I licence from scratch, as well as access to Siiibo’s existing investor base. The company plans to use the platform to develop and distribute yield products linked to its Bitcoin holdings.

"Japanese households hold roughly $7.4tn in cash, deposits and low-yield products, and as Japan shifts from deflation to inflation, that capital has begun searching for yield," Gerovich wrote on X.

Metaplanet has previously stated plans to partner with businesses involved in digital asset custody, stablecoin payments, collateralized lending and Bitcoin-related software and hardware.

Bitcoin treasury remains core holding

Metaplanet held 40,177 BTC as of 31 May, with a net asset value of over $2.8bn. In its most recent earnings, the company reported a net loss of ¥114.5bn ($730mn) for Q1 FY2026, driven by a ¥116.4bn ($740mn) unrealized valuation loss on its Bitcoin holdings under Japanese GAAP. This more than offset a 282.5% year-on-year surge in operating profit to ¥2.3bn. The company has borrowed $302mn against its Bitcoin via a $500mn collateralized credit facility.

The acquisition will be funded from cash and borrowings. Metaplanet has also indicated it may draw further on its Bitcoin-backed credit facilities.
