Three exchanges under one roof. SBI Holdings filed a letter of intent to acquire Bitbank on May 1, 2026, and the move is less surprising than the speed behind it. In under 30 days, the group has already absorbed Bitpoint Japan through SBI VC Trade and is now targeting the last major independent exchange left in Japan.
SBI Holdings President Yoshitaka Kitao was direct in the official statement: bringing Bitbank into the group would “establish a dominant position in the domestic crypto sector.” For a company with a market capitalization of roughly 1.48 trillion yen, according to Tokyo Stock Exchange data, that kind of language is a strategy, not a slogan.
Bitbank: Twelve Years, Zero Security Incidents
Founded in May 2014, Bitbank has built one of the cleanest track records in Japanese crypto: no security breaches across twelve years of operation. That matters enormously in a market still living in the shadow of the Mt. Gox collapse. SBI recognized the commercial value of that record immediately.
The group intends to make Bitbank a consolidated subsidiary, pending two mandatory steps: due diligence and approval from Japan's Financial Services Agency (FSA). Standard timelines for transactions of this kind run three to six months, which places a hypothetical close somewhere between late 2026 and early 2027.
Bitbank had been pursuing an independent listing on the Tokyo Stock Exchange, a plan in development since mid-2025. That path is now effectively closed. Joining a conglomerate and listing independently are incompatible trajectories. In 2021, Mixi invested 7 billion yen in Bitbank for a 26.2% stake, according to company disclosures. That shareholding position now waits on whatever structure SBI negotiates.
Visa Card, Singapore, and the Regional Play
Functionally, four days before the acquisition announcement, on April 27, Bitbank launched Japan's first crypto-linked credit card in partnership with EPOS Card Co. The “EPOS CRYPTO Card for bitbank” runs on the Visa network and offers a 0.5% cashback in cryptocurrency on monthly purchases. SBI is acquiring an exchange that has already made the leap into retail payments.
The broader strategy is visible. In February, SBI signed an agreement for a majority stake in Coinhako, a MAS-regulated exchange in Singapore. Separately, SBI launched a dedicated blockchain for tokenized asset trading with Web3 firm Startale, designed for 24-hour institutional operations. Three fronts: domestic Japan, Southeast Asia, and real-world asset infrastructure.
The regulatory calendar is pushing everything forward. On April 10, 2026, the Japanese government approved an amendment to the Financial Instruments and Exchange Act that reclassifies crypto assets as financial instruments, placing them on equal legal footing with stocks and bonds. If the Diet ratifies the text, the new rules take effect in fiscal year 2027.
For platforms unprepared for that shift, the FIEA deadline is a problem. For SBI, it's a window. As WuBlockchain wrote in a post on X on May 1: “SBI is consolidating the domestic crypto sector at a rapid pace. The timing is deliberate.”
SBI Holdings shares (5839.T) saw a notable uptick in trading volume on May 1, per TradingView data, signaling that the market has priced in the strategic weight of the deal. With Bitbank, SBI VC Trade, and the former Bitpoint Japan under one roof, Kitao is not assembling a simple exchange group. What SBI is building looks more like the crypto infrastructure backbone for Northeast Asia, timed precisely to the FIEA transition.
