bitFlyer
Regulated Japanese crypto exchange offering custody, trading, and IEO services.
On the record
Checkpoint: SBI-Bitbank merger closes, resetting Japan's custody rankings
The call
bitFlyer still leads Japan's regulated exchange market but is losing ground on custody, IPO timing, and product speed to both a domestic rival and AI-driven trading tools.
bitFlyer lets people in Japan, New York, and Europe buy and sell cryptocurrencies and holds their money safely under government rules. It is hard to copy because getting those government licenses takes years and millions of dollars, which is why AI software alone cannot replace it. However, SBI Holdings just bought a bigger competitor called Bitbank in June 2026, megabanks are entering the market with their own products, and bitFlyer promised to go public in January 2025 but has not yet, leaving its owners stuck without an exit. The one thing that could change everything is if bitFlyer finally goes public, if the crypto market bounces back from being down half its value, or if SBI's larger combined platform stumbles.
Why
01
AI pressure: Bitrue's AI trading copilot. Bitrue's July 2026 AI copilot targets retail trading UX, an area where bitFlyer has shipped no AI feature yet. Could AI do the core job? Unlikely.
02
Bigger players: SBI Holdings (via Bitbank acquisition, June 2026). SBI's Bitbank deal creates a combined ~¥1.1T custody base, overtaking bitFlyer's ¥960B and Japan's custody lead. Could a giant copy it? Probably.
03
What protects it. Licenses from Japan's FSA, NYDFS, and EU MiCA give bitFlyer regulatory access that new AI or crypto entrants cannot copy quickly.

Named risks

- IPO repeatedly promised (Jan 2025) but not closed by mid-2026, leaving no equity liquidity path.
- Unresolved CEO identity conflict (Kano vs Hayashi) signals possible unreported governance issue.
- Crypto market down about 50% from ATH as of July 2026 pressures trading volume and custody values.
- Peer AI trading tools (Bitrue) commoditize trading UX layer while bitFlyer shows no in-product AI.

Questions people ask
- Is bitFlyer profitable in 2026?
- Exact profitability figures are not disclosed publicly. bitFlyer is privately held, and third party revenue estimates (around $12.5M) appear stale relative to its scale, with custody assets around 960 billion yen as of December 2025, per a June 25, 2026 report.
- Is bitFlyer going to IPO?
- CEO Yuzo Kano said in a January 6, 2025 report he wanted to pursue an IPO 'in the next few months', but no listing had closed as of mid 2026, and no bitFlyer entry appears in 2025 US IPO trackers as of December 22, 2025.
- Who is bitFlyer's biggest competitor?
- SBI Holdings poses the sharpest threat: its June 25, 2026 announced acquisition of Bitbank for 289 million dollars would create a combined custody base of about 1.1 trillion yen, surpassing bitFlyer's roughly 960 billion yen as of December 2025.
- Could AI replace bitFlyer?
- No. bitFlyer's Japan FSA registration, NYDFS BitLicense, and EU MiCA CASP license (first for a Japan-originated exchange, approved July 1, 2026) require regulated legal entities for custody and fiat settlement, which pure AI products cannot substitute for.
- Who owns bitFlyer?
- bitFlyer is privately held. Co-founder Yuzo Kano personally holds roughly 40% of the company, per a March 30, 2023 report, and was reinstated as CEO that month following a shareholder vote after a governance dispute.
- Who is bitFlyer's CEO?
- Most 2026 sources, including a June 30, 2026 bitFlyer disclosure, name Yuzo Kano as CEO, but a Wikipedia snapshot from July 21, 2026 lists 'Kuniyoshi Hayashi' as CEO instead, an unresolved discrepancy in current reporting.
