SBI to Acquire Bitbank in $289 Million Deal as Japan’s Crypto Exchange Industry Consolidates

MakeCryippreferred on

Japan’s financial conglomerate SBI Holdings has agreed to acquire cryptocurrency exchange Bitbank in a transaction valued at approximately ¥46.7 billion ($289 million), advancing a broader consolidation trend in Japan’s regulated digital asset industry.

The companies signed a basic agreement and share transfer agreement on June 25. The acquisition will be carried out through SBI’s wholly owned subsidiary, SBICAH LLC, with the initial share transfer expected in August and the overall transaction targeted for completion around October, subject to regulatory approvals.

Bitbank said customers will continue using its exchange without interruption during the ownership transition, adding that existing trading and custody services will remain unchanged.

A strategic expansion rather than a rescue

Unlike many exchange acquisitions driven by financial distress, Bitbank enters the transaction from a position of operational stability. The exchange has built its business around spot cryptocurrency trading, lending services, and payment products while maintaining a reputation for strong security in Japan’s tightly regulated crypto market.

The acquisition allows SBI to add an established exchange platform instead of building additional infrastructure internally, while giving Bitbank access to the capital, compliance resources and financial ecosystem of one of Japan’s largest financial groups. The deal reflects a growing preference among Japanese financial institutions to expand through acquisitions rather than launch new crypto businesses from scratch.

Transaction highlights

• Acquirer: SBI Holdings via SBICAH LLC
• Target: 100% ownership of Bitbank
• Deal value: Approximately ¥46.7 billion ($289 million)
• Share transfer: Expected around August 2026
• Completion target: Around October 2026, pending regulatory approvals

Following completion, Bitbank will no longer be an equity-method affiliate of existing shareholders MIXI Inc. and Ceres Inc.

Bitbank strengthens SBI’s digital asset ecosystem

Founded in 2014, Bitbank has grown into one of Japan’s leading licensed cryptocurrency exchanges. Beyond spot trading, the company has expanded into crypto lending and recently introduced crypto-linked payment services, reflecting the industry’s shift toward broader financial applications.

For SBI, Bitbank adds another regulated exchange to an expanding digital asset portfolio that already includes SBI VC Trade. The group has spent the past year broadening its presence across crypto trading, stablecoins, tokenized assets, digital payments and custody infrastructure, with the SBI Holdings stablecoin initiatives further reinforcing its long-term digital asset strategy.

Once integrated, SBI expects its combined crypto businesses to oversee roughly ¥1.1 trillion in customer assets across approximately 2.92 million accounts, positioning the group among Japan’s largest cryptocurrency operators by assets under custody and customer base.

Regulation is reshaping Japan’s exchange market

The acquisition comes as Japan prepares for a more comprehensive regulatory framework for digital assets. Authorities are considering moving crypto assets under legislation more closely aligned with the Financial Instruments and Exchange Act, a shift expected to introduce stricter governance, disclosure and compliance standards for exchanges. Those requirements could increase operating costs for smaller platforms while encouraging consolidation among regulated operators. The Bitbank Polymarket warning also highlighted Japan’s cautious stance toward offshore prediction markets and reinforced the importance of regulatory compliance within the country’s crypto sector.

SBI has positioned itself ahead of those changes by steadily expanding its crypto operations. Earlier this year, the company integrated Bitpoint Japan into SBI VC Trade, launched crypto rewards payment products, and introduced RLUSD-related services in Japan through its digital asset businesses.

Industry analysts view the Bitbank acquisition as another step toward building an integrated digital asset platform that combines exchange services with banking, securities, payments and tokenization under a single financial group.

What happens next?

Before the acquisition is finalized, several milestones remain:

• Regulatory approval from Japanese authorities
• Completion of the scheduled share transfer
• Capital restructuring and share repurchase process
• Final integration into the SBI Group

Neither SBI nor Bitbank has announced immediate changes to the exchange’s branding, listed assets, fee structure or customer accounts. For users, the short-term impact is expected to be minimal. The longer-term significance lies in how the acquisition strengthens institutional participation in Japan’s crypto market at a time when regulatory expectations and competitive pressures continue to rise.
