SBI Holdings agreed to acquire Tokyo-based crypto exchange Bitbank, which roughly doubles its crypto assets under custody to 1.1 trillion yen and increases customer accounts by nearly 1 million million, according to Decrypt’s coverage and CoinDesk’s coverage. This deal makes SBI the largest crypto exchange operator in Japan by asset value, a $289 million Bitbank purchase that reflects ongoing consolidation in Japan’s crypto market: Architect Partners, who explain how this trend reshapes market share concentration among fewer players.

SBI Holdings, a diversified financial services group worth nearly $11 billion, announced the purchase of Bitbank in late June 2026. Bitbank manages 570 billion yen, or roughly $3.5 billion, in assets under custody and serves about 960,000 crypto accounts, per CoinDesk and Kucoin’s report data. When combined with SBI’s existing exchange, SBI VC Trade, the platform will hold around 1.1 trillion yen across 2.9 million million accounts, cementing SBI’s leadership in Japan’s regulated crypto sector.

CoinDesk reveals that nearly 90% of Japan’s licensed crypto exchanges operate at a loss. Half of the 27 registered exchanges face closure risk. Bitbank reported a fiscal 2025 operating loss amid a 27% revenue drop.

Regulatory Reforms Driving Market Consolidation

Japan’s lower house passed legislation on June 11, 2026, which places crypto assets under the Financial Instruments and Exchange Act transferring. CoinDesk reports that this move aligns digital assets with securities laws, enforcing stricter compliance and transparency while reducing crypto gains tax to a flat 20%, down from higher progressive rates. This tax cut gives investors a more predictable cost framework.

Among Japan’s 27 registered exchanges, about half face viability challenges due to these reforms, as CoinDesk states. High compliance expenses and legal uncertainty have pushed vigorous players like SBI to acquire weaker platforms, consolidating liquidity and customer bases in the process.

Market Impact and Scale Effects

Combining SBI VC Trade with Bitbank lifts assets under custody to approximately 1.1 trillion yen and expands the platform to about 2.9 million active crypto accounts, per Decrypt. This increased volume and customer aggregation should bring SBI operational efficiencies, lower transaction costs, and improve liquidity pools. Kucoin

How the Acquisition Will Be Structured

The deal is expected to close by October 2026, pending regulatory approvals. The Japan Fair Trade Commission’s review should finish before this date. According to Pricepredictions’ report, SBI will first purchase shares from Bitbank’s founders and individual shareholders in August, then proceed to buy out stakes held by corporate shareholders MIXI and Ceres by October’s end.

SBI’s Strategy in Stablecoins and Tokenized Financial Markets

SBI aims to capitalize on the expanding market for tokenized real-world assets, which global trends suggest could hit sizable scale by 2033, per CoinDesk.

The acquisition places SBI at the forefront of Japan’s crypto consolidation amid rising regulatory scrutiny and industry rationalization, according to Kucoin and CoinDesk. Serving nearly 3 million combined accounts boosts SBI’s edge in customer reach, asset custody, and compliance capacity.

Smaller exchanges face user and revenue declines, reflecting a survival-of-the-fittest dynamic. The licensed exchanges might reduce from 27 to a more robust group able to meet stricter standards. SBI’s Bitbank deal shows how consolidation leverages regulatory clarity and scale to grow market share in Japan’s evolving crypto economy, per CoinDesk.

Future Implications for Japan’s Crypto Market

The Bitbank acquisition marks a major shift triggered by regulatory reform, according to Pricepredictions and market experts. By 2027, crypto assets will fully fall under Japan’s Financial Instruments and Exchange Act, imposing tighter rules that will likely drive further consolidation.

Structural Shift Toward Regulated Scale

SBI’s acquisition of Bitbank signals Japan’s crypto market moving toward fewer, larger regulated entities. Bitbank brings $3.5 billion in assets and nearly 1 million client accounts to SBI, affirming SBI’s claim as a strategic market leader amid regulation and competitors’ struggles. According to Decrypt, the consolidation is critical to securing market stability and integrating crypto within Japan’s financial system, as SBI Holdings declares.

SBI is acquiring Bitbank for approximately $289 million, a valuation of 46.7 billion yen.
