Japanese Banking Conglomerate SBI Finalizes Acquisition of Bitbank, Establishing Dominant Crypto Platform
SBI Holdings completed its acquisition of Japanese cryptocurrency exchange Bitbank on October 1 for approximately ¥46.7 billion, making it a wholly owned subsidiary and consolidating SBI's crypto operations. The combined entity now manages roughly ¥1.1 trillion in crypto assets across approximately 2.92 million accounts, positioning it as Japan's largest crypto platform by custodied assets. The acquisition represents part of a broader consolidation trend in Japan's regulated crypto market, driven by increasing compliance costs and regulatory shifts including proposed flat-rate taxation on crypto gains.
SBI Holdings has consolidated its Japanese cryptocurrency operations by absorbing Bitbank into a single entity managing over 1.1 trillion yen in digital assets. The October 2026 transaction involved Bitbank retiring shares held by major investors MIXI and Ceres, leaving SBI as the sole shareholder. This combined platform now serves approximately 2.92 million accounts with spot trading, lending, and custody services denominated in Japanese yen.
The consolidation reflects structural pressures reshaping Japan's crypto sector. Regulatory requirements under the upcoming Financial Instruments and Exchange Act and proposed flat taxation on crypto earnings are increasing operational costs for independent exchanges. SBI has pursued an aggressive acquisition strategy, previously absorbing TaoTak in 2020 and assuming customer accounts from DMM Bitcoin following its 2024 security breach, while expanding internationally with stakes in Singapore-based Coinhako and U.S. blockchain platforms.
The acquisition may reshape Japan's retail crypto market, potentially reducing competition among regulated platforms while creating a dominant operator with consolidated custodied assets. Smaller independent exchanges could face increasing pressure to either consolidate or exit the market. However, the transition could improve consumer protections through unified compliance standards and stronger operational infrastructure. Market participants and regulators may observe whether concentration enhances or inhibits innovation and access to crypto services for Japanese investors.
