SBI Holdings is buying Bitbank for JPY 46.7 billion (around $300 million) in a deal that would combine the exchange with SBI VC Trade and create Japan's largest crypto platform group by custody assets.
The agreement was signed June 25, 2026, through SBI Crypto Asset Holdings GK (SBICAH), a wholly owned SBI subsidiary. The transaction still needs clearance from Japan's Fair Trade Commission before it can close.
If approved, the combined group would hold roughly 1.1 trillion yen (about $7 billion) in crypto assets under custody and around 2.92 million accounts, SBI said in a filing.
"Upon completion of the transaction, based on a simple aggregation of the figures of SBI VC Trade and Bitbank as of April 30, 2026, the Company Group is expected to have approximately JPY 1.1 trillion in assets under custody and approximately 2.92 million crypto asset accounts," SBI said.
The deal structure mixes share purchases and new share issuance. Bitbank will use funds from the capital increase to buy treasury shares from MIXI and CERES. After those steps, SBI expects to indirectly hold 100% of Bitbank's voting rights through its subsidiary.
Bitbank has operated out of Tokyo since 2014. One detail SBI highlighted in its filing: the exchange has maintained zero hacking incidents since founding.
Its financial performance has tracked the crypto cycle. Net sales jumped from 3.86 billion yen in 2023 to 7.95 billion yen in 2024, then dropped to 5.82 billion yen in 2025. Operating income swung from a 2.80 billion yen gain in 2024 to a 970 million yen loss in 2025.
SBI is betting that combining Bitbank's user base and trading activity with its own platform will create a larger domestic crypto group. The company noted that the combined entity "is expected to rank first in terms of assets under custody and to be among the top class in terms of number of accounts" among Japanese crypto exchanges.
Beyond scale, SBI pointed to stablecoins and on-chain finance as areas it wants to build out using the combined platform.
The first phase of the deal is expected around August 2026, with full completion targeted for October 2026 after regulatory approvals and other closing conditions.
Japan's three largest banks announced plans Wednesday to jointly issue a yen-pegged stablecoin and begin live commercial transactions before March, signaling broader institutional interest in the country's crypto infrastructure.
