SBI Holdings has completed its takeover of Japanese crypto exchange Bitbank, closing a deal worth roughly 46.7 billion yen and folding one of Japan’s best-known trading platforms into the country’s largest online financial group — with promises that nothing changes for customers.

In an announcement on Oct. 1, Bitbank confirmed it had completed the repurchase of shares held by MIXI and Ceres, the final step in a multistage acquisition agreed with SBI Holdings earlier this year. The exchange is now a wholly owned subsidiary of the SBI group. For Bitbank’s users, the immediate takeaway is reassurance: the company said existing services continue unchanged, and customers can keep using the exchange exactly as before. The bigger story is what the deal says about Japan’s consolidating crypto market — where giants are swallowing standalone exchanges one by one.
The Hook: A 46.7 Billion Yen Deal, Done in Stages
This was never a simple purchase. SBI pursued the acquisition through its wholly owned unit SBICAH GK in a sequence designed around Bitbank’s existing shareholders. First, SBICAH acquired 53,704 Bitbank shares from CEO Noriyuki Hirosue and other individual shareholders. Bitbank then issued 48,952 new shares to the SBI unit through a third-party allotment, with those funds used to buy back the stakes held by MIXI and Ceres. Completing those repurchases on Oct. 1 closed the remaining steps and left SBI as Bitbank’s sole parent. The full transaction was valued at roughly 46.7 billion yen, including share transfers and the capital injected through the allotment.
The Backstory: From Planned Listing to Group Shelter
The path here took years. Bitbank had previously pursued a possible public listing in Japan, and MIXI became one of its major shareholders through a capital and business alliance back in 2021. SBI first disclosed in May that it was considering buying Bitbank shares and making the exchange a consolidated subsidiary, subject to due diligence and internal approvals. SBI’s board approved the definitive agreement in June. Instead of braving public markets alone, Bitbank ends up inside a financial conglomerate with banking, securities and insurance arms — a pattern increasingly common in a market where regulatory compliance costs favor deep-pocketed parents.
The Core Conflict: Two Exchanges, One Group
The deal raises an obvious question: SBI already runs its own crypto exchange, SBI VC Trade, which handles trading, custody and digital asset services in Japan. Why own two? The management reshuffle hints at the answer — integration rather than competition. Tomohiko Kondo, president of SBI VC Trade, has joined Bitbank’s board, while Bitbank CEO Noriyuki Hirosue stays on as representative director, president and CEO and takes a planned outside director position at SBI VC Trade. Three outside directors — Satoshi Takagi, Nobuhiro Kanayama and Masaya Kubota — stepped down as part of the new structure. Bitbank said it plans to tap SBI Group’s financial functions, customer network and management resources to grow its exchange and digital asset businesses. Notably, this is SBI’s second exchange absorption: Bitpoint Japan was folded into SBI VC Trade in April 2026.
Market Implications: SBI’s Digital Asset Empire Grows
Beyond exchanges, SBI has been assembling a full digital asset stack, and Bitbank slots into it:
- Stablecoins — SBI VC Trade became the distribution platform for Ripple USD after RLUSD launched in Japan in June following regulatory approval, and the group is developing yen-based stablecoins through its JPYSC project, issued via SBI Shinsei Trust Bank.
- Cross-border payments — In September, SBI and Kyobo Life Insurance completed a Korea-Japan test using yen and won stablecoins on the Canton Network, handling transfers, FX and settlement without routing through the U.S. dollar.
- Institutional infrastructure — In July, SBI led a 76 million USD Series C round for U.S. exchange operator EDX Markets to support its trading, clearing and settlement expansion.
For regular investors, consolidation cuts both ways. A bigger, better-capitalized parent can mean stronger security, deeper liquidity and more product offerings — Bitbank already offers spot trading plus an EPOS Crypto Card arrangement letting eligible users settle monthly credit card bills with bitcoin held through the exchange. On the other hand, fewer independent exchanges means less competition, and Japanese traders now face a market where a handful of group-owned platforms dominate.
The Verdict
Bitbank customers should notice nothing beyond a new board — same services, same app, same arrangements. But the deal is a landmark for Japan’s crypto market: the country’s largest online brokerage group now directly controls two major exchanges, a stablecoin pipeline and institutional trading infrastructure spanning Tokyo and New York. Japan was early to license crypto exchanges, and it is now leading a second phase — consolidation under traditional financial giants. If you hold assets on Bitbank, nothing needs doing today; just remember your counterparty is now part of a much larger machine, which is arguably a strength in a market where exchange failures, not regulation, have historically cost users the most.

46.7 billion yen for one of the last independents is cheap when you count the license alone. SBI bought market share at a discount
been trading on bitbank since 2018. as long as the fee schedule stays put i am fine, but sbi owning everything in japan makes me a bit nervous
consolidation is brutal out there. bitpoint folded into sbi vc trade in april, now bitbank. give it 5 years and 3 exchanges will be left
3 might be generous. sbi and mufg are basically eating the whole market at this point
kondo from vc trade joining the bitbank board says everything. merge is coming, just a matter of when
46.7 billion yen and the official message is nothing changes for users, trust us. meanwhile MIXI and Ceres quietly took their exit at the top of the cycle
SBI keeps swallowing every standalone exchange in Japan. few more years and its one group, one app, zero negotiating power for users. consolidation never ends well for fee schedules
one app zero negotiating power is exactly right. sbi already sets the fee floor the others follow, no chance this makes spreads better for anyone trading jpy pairs
fee floor already moved once when they absorbed the last exchange. expecting anything different this time is optimism
MIXI cashing out at 46.7 billion yen after holding since the early days is the cleanest exit you will see all cycle. someone at that fund called the top
bitbank was one of the last independents that actually worked. watch the spread widen 6 months after the integration finishes and everyone pretends its always been like that
six months is generous, the last integration showed up in the spreads around month three. same playbook, bigger target
services unchanged is what every exchange says at close. ask again when the sbi vc trade migration notice drops, thats when the fee table gets quietly rewritten
