Summary
The transaction structure unfolds in two phases. An SBI subsidiary will begin purchasing Bitbank shares from individual investors and the exchange's founder starting in August 2026, with existing institutional shareholders MIXI and Ceres selling their stakes by the end of October. This phased approach allows SBI to methodically increase its ownership while managing shareholder transitions. Upon completion, SBI's total crypto holdings across its consolidated exchange operations are projected to exceed the ¥1 trillion threshold, substantially outpacing domestic competitors bitFlyer and Coincheck.
The acquisition builds on a capital and business alliance initially disclosed in May 2026, reflecting SBI's methodical approach to full operational control. Bitbank has established itself as a leading domestic trading venue and recently expanded its service offerings through Japan's first crypto-linked credit card in partnership with EPOS Card. The timing proves strategic, as Japan's regulatory environment shifts toward stricter oversight under pending reforms that would classify digital assets under the Financial Instruments and Exchange Act, imposing heightened compliance and capital requirements on market participants.
SBI's acquisition strategy reflects broader consolidation efforts across the Japanese crypto sector. The company has previously integrated DMM Bitcoin customer accounts and BITPoint Japan into its operating structure. Beyond domestic expansion, SBI is pursuing a majority investment in Singapore-based Coinhako to strengthen its positioning across Asian digital asset markets, signaling ambitions to leverage domestic market dominance into regional scale.
Combined crypto assets under custody across the consolidated SBI platform will reach approximately $6.2 billion, substantially reinforcing the company's competitive moat in Japan's institutional and retail crypto trading landscape amid an evolving regulatory framework.
