Metaplanet finalized its 100% acquisition of Siiibo Securities — a licensed Type I securities firm, pioneer of Japan’s online corporate bond market. Not a partnership. Not a joint venture. Full acquisition. That closing is what unlocks the WebX 2026 announcement chain: bonds, preferreds, and structured products issued against a Bitcoin balance sheet. Not an aspiration — a licensed platform, owned. The Capitalist read: Saylor built Strategy inside a decade of software cash flow. Metaplanet is compressing the same evolution into 18 months by acquiring the rail, not renting it. Vertical integration lowers cost of capital and speeds structured-product iteration.
