SBI Holdings now owns all of bitbank. The company said on October 1, 2026 that bitbank had bought its own shares from MIXI and Ceres that day, completing the transaction and making the crypto-asset business a wholly owned subsidiary.
How the exit worked
The route was a buyback, not a direct sale to SBI. SBI described the final step as bitbank's repurchase of treasury shares from the two sellers. SBI had announced the deal on June 25, 2026, and its completion notice gives no purchase price or regulatory step.
Ceres, which carried bitbank as an equity-method affiliate, supplied the numbers. It sold all 21,480 of its bitbank shares for ¥8.61bn, leaving it with zero shares and a 0% voting stake.
The day before, on September 30, bitbank issued new shares by third-party allotment to SBICAH, a wholly owned SBI Holdings subsidiary. That removed bitbank from Ceres's equity-method affiliates as of September 30.
What it means for the books
Ceres expects a gain of about ¥2.5bn from the change in its equity interest, to be booked in the third quarter of its year to December 2026. It also expects a gain of about ¥3.2bn on the sale of investment securities, recorded on October 1. Together that is about ¥5.7bn in special gains, which Ceres said is little changed from its June 25 estimate and already built into its full-year forecast. The amounts may still move.
SBI called the effect on its consolidated results for the year to March 2027 minor.
bitbank is based in Tokyo's Yaesu district, was founded on May 7, 2014, and has capital of ¥8.05bn including capital reserve. The SBI release does not give MIXI's share count or sale price.
