Metaplanet Agrees To Acquire Siiibo Securities For 2.1 Billion Yen To Launch Bitcoin Yield Products

Tokyo-listed Metaplanet has agreed to acquire Siiibo Securities Co., Ltd. in a 2.1 billion yen (around $13.1 million) deal, entering a share transfer agreement to purchase all outstanding shares and make it a wholly owned subsidiary.

The acquisition, described as the first major transaction under Metaplanet’s “Project Nova” initiative, is set to close around July 13, 2026, with existing customer services at Siiibo Securities remaining uninterrupted and the current management team largely staying in place.

After completion, Siiibo Securities will be rebranded as Metaplanet Securities, and the company expects the transaction to have a negligible effect on its consolidated financial results for the fiscal year ending December 2026.

Metaplanet said it aims to build a Bitcoin-focused financial platform that bridges traditional capital markets with innovative cryptocurrency offerings, using a regulated securities license to accelerate development of yield-generating products tied to Bitcoin, security tokens, and digital credit solutions.

Metaplanet framed the move as the “first step” in “Project Nova,” with CEO Simon Gerovich saying the company views Bitcoin as “the foundation of the next generation of financial ecosystems.”

In the same Project Nova context, Metaplanet said it intends to develop and distribute Bitcoin-related yield products directly to Japanese investors, supported by its Bitcoin holdings of 40,177 BTC on its balance sheet.

CryptoRank reported that Metaplanet plans BTC-linked bonds, joint underwriting, a security token pilot, and distribution to ~250,000 shareholders, funded by cash, borrowings, and optional Bitcoin-backed credit lines up to $500 million.

CryptoRank also said the deal gives Metaplanet a Type I Financial Instruments Business Operator registration, positioning the group to begin offering Bitcoin-linked investment products to individual Japanese investors through the renamed Metaplanet Securities.

Metaplanet’s securities expansion lands as Japan’s market infrastructure firms test how digital assets could fit into existing capital markets, including a plan by the Japan Securities Clearing Corporation to launch a proof of concept with Mizuho, Nomura, and Digital Asset to test Japanese government bonds as digital collateral using the Canton Network.

The same coverage tied the timing to a reported shift in Japan’s Lower House, which “reportedly passed a bill on Thursday that would bring crypto assets under Japan’s financial instruments framework,” potentially opening the door to crypto exchange-traded funds and improved tax treatment for digital assets.

Decrypt’s account of the transaction emphasized that Metaplanet expects the acquisition to close in July and that Siiibo Securities will become a wholly owned subsidiary renamed Metaplanet Securities, with the goal of issuing and distributing BTC-backed financial products.

Across the reporting, the core watch item going forward is how Metaplanet translates its treasury-backed positioning into actual offerings through Metaplanet Securities, including what the product terms look like and how they comply with Japan’s evolving treatment of digital assets in the financial instruments framework.
