Architect Partners posits that SBI is primarily acquiring a regulated operational scale rather than immediate earnings. This strategy is in direct response to Japan's evolving and increasingly stringent digital asset regulations, which are making it more challenging for standalone exchanges to operate profitably. The acquisition will substantially boost SBI’s crypto assets under custody, nearly doubling them to approximately 1.1 trillion yen, and significantly expanding its customer base by adding almost 1 million accounts.
This move by SBI Holdings, a diversified financial services group with a market capitalisation of around $11 billion, aligns with its long-term strategy of achieving growth through mergers and acquisitions rather than organic expansion. This approach is not new for the company; its SBI VC Trade unit previously integrated TaoTao in 2020, absorbed DMM Bitcoin’s customer accounts and custody assets in 2024, and fully integrated Bitpoint Japan (wholly owned by SBI since 2023) in April of the same year.
The addition of Bitbank, which currently manages 570 billion yen ($3.5 billion) in assets under custody and serves 960,000 accounts, will bring SBI's combined platform to an impressive 1.1 trillion yen in assets under custody across 2.9 million accounts. This firmly positions SBI to become a dominant force in Japan's regulated digital-asset market.
Steve Payne, co-founder and partner at Architect Partners, expects this trend of consolidation to persist. He predicts that as the market thins out, other major players like bitFlyer, a prominent independent and private-equity-owned exchange, could be the next to be acquired. Furthermore, foreign platforms aiming to enter the Japanese market are likely to find acquiring an existing licensed entity more efficient and cost-effective than building one from scratch.
SBI Holdings, based in Tokyo, is recognised as one of Japan's most proactive traditional finance participants in the digital asset sector. Its extensive involvement spans crypto trading, liquidity provision, tokenisation, stablecoins, and blockchain-based settlement solutions. Bitbank, a key player in the Japanese crypto landscape, is one of the nation's largest licensed cryptocurrency exchanges, offering a range of services from spot trading to custody for both retail and institutional clients amidst a brisk M&A environment in 2026 for crypto firms.
