Metaplanet is positioning its ¥2.1 billion acquisition of Japanese broker-dealer Siiibo Securities as the foundation for bitcoin-linked bond issuance, a move that could give companies with Bitcoin treasury strategies a domestic route to raise fixed-income capital for additional BTC purchases.
The plan, described by Metaplanet director of bitcoin strategy Dylan LeClair in a meeting with Benchmark analysts, centers on a proposed product called “Bitbonds.” The instruments would be tied to Bitcoin and designed to offer yields of roughly 4% to 6%, according to Benchmark’s note. Metaplanet ultimately aims to move issuance and settlement on-chain, using stablecoins and a secondary market for trading the debt.
Siiibo Securities brings a Type-1 Financial Instrument Business Operator license, a regulatory authorization that permits the structuring and distribution of securities in Japan. LeClair told Benchmark that securing such a license independently can take at least several quarters, making the acquisition a faster route into securities issuance than building a licensed operation from scratch.
Broker-dealer acquisition expands Metaplanet’s funding options
Metaplanet has built its public-market identity around accumulating Bitcoin, and the Siiibo purchase extends that strategy beyond equity issuance and conventional corporate financing. A broker-dealer platform could allow the company to structure debt products for its own use and, over time, offer financing tools to other businesses seeking to establish or expand Bitcoin treasury positions.
The proposed Bitbonds would sit at the intersection of corporate debt and Bitcoin-linked treasury management. Fixed-income buyers would receive a targeted yield, while issuers could use the proceeds to acquire BTC. The arrangement could appeal to companies that want Bitcoin exposure but prefer financing structures that do not rely solely on issuing new shares, which can dilute existing shareholders.
That model also presents clear execution challenges. The terms of any eventual bond, including its collateral, Bitcoin-price exposure, repayment protections, eligible buyers, and treatment under Japanese securities rules, will determine whether it resembles a conventional corporate note with Bitcoin-related features or a more novel crypto-linked security. Metaplanet has outlined the concept and expected yield range, but has not publicly detailed final issuance terms in the information provided.
Project nova links treasury strategy with financial infrastructure
The debt platform is part of Metaplanet’s longer-term “Project Nova” roadmap, which combines acquisition plans for cash-flowing businesses with the creation of Bitcoin-focused financial infrastructure. The approach suggests the company is seeking to develop recurring financial-services revenue alongside gains or losses tied to the Bitcoin held on its balance sheet.
That distinction could become increasingly relevant as Metaplanet’s BTC holdings grow. Benchmark said the company holds 43,000 BTC, valued at nearly $2.8 billion in its note, placing it third among publicly traded Bitcoin treasury companies in the compiled rankings cited by the firm. At that scale, financing decisions can materially affect how quickly the company expands its holdings and how much market risk it takes to do so.
A securities platform could also give Metaplanet more control over the design and distribution of its funding products. Rather than approaching a bank or outside securities firm for each transaction, an in-house licensed subsidiary would allow the group to develop specialized issuance capabilities. The company’s stated ambition to add on-chain issuance and stablecoin settlement would seek to reduce operational friction in the bond lifecycle, though that phase remains a longer-term objective rather than an announced launch.
A test of demand for bitcoin-linked fixed income
The proposed 4% to 6% yield range places Bitbonds in a market where buyers will likely focus closely on the issuer’s credit profile, Bitcoin volatility, and the legal rights attached to the notes. Companies using debt to buy Bitcoin can benefit if the asset appreciates, but the same structure can increase pressure on the issuer if BTC declines sharply or refinancing conditions deteriorate.
Metaplanet’s approach may therefore be most relevant to corporate treasuries that already accept Bitcoin’s price risk and want alternatives to direct equity fundraising. A bond structure could match different pools of capital: some buyers may seek contracted income rather than direct BTC ownership, while issuers may seek to preserve more upside from their Bitcoin holdings.
Benchmark maintained its buy rating on Metaplanet and set a ¥405 price target, equivalent to about $2.47 in the note. The broker’s view rests in part on the prospect that Metaplanet can turn its Bitcoin treasury strategy into a financial-services platform rather than remain only a corporate BTC holder.
For now, the acquisition of Siiibo provides the regulatory and operational base for that ambition. The next measure of Project Nova’s progress will be whether Metaplanet can translate the Bitbonds proposal into a defined offering with terms that satisfy Japanese securities requirements and attract fixed-income buyers willing to finance Bitcoin-focused corporate balance sheets.
