SBI builds out a broader crypto stack with Bitbank, EDX, Gauntlet and Solana
SBI Holdings has stepped up its digital-asset push through a string of deals that span Japanese retail trading, U.S. institutional market infrastructure, on-chain risk management and stablecoin distribution. In less than a month, the Japanese financial group agreed to acquire licensed exchange Bitbank for 46.7 billion yen, led EDX Markets’ $76 million Series C, made a sole $125 million investment in Gauntlet, and announced a strategic partnership with the Solana Foundation. The sequence marks a noticeable shift for SBI, which has historically favored joint ventures, strategic stakes and outright acquisitions rather than taking the lead in venture rounds. The transactions also line up with several layers of SBI’s broader strategy: retail access in Japan, institutional trading and settlement rails abroad, on-chain treasury and vault management, and a domestic market for regulated stablecoins and tokenized real-world assets. Analysts and investors interviewed by The Block said the company appears to be assembling financial “pipes” rather than simply adding crypto exposure, while SBI said the recent acquisitions, investments and partnerships are part of a group-wide move toward an on-chain transition.
