Market Context 2025 — Digital Banking’s Acceleration
The digital-banking market has matured into a core pillar of U.S. consumer finance. By 2025, neobanks control roughly 22% of new checking-account openings, according to McKinsey Digital Banking Survey 2025. Rapid adoption is driven by convenience, instant onboarding, and higher interest yields on deposits compared with traditional branch banks. The industry’s key differentiator is technology: API-based systems allow real-time transactions, integrated budgeting tools, and predictive analytics for customer behavior.
Major players—SoFi Bank, Chime, Varo Bank, and Revolut U.S.—operate under full or partner-bank charters. Their agility in adjusting savings rates and launching new features like early-pay access or crypto-linked accounts reflects how financial technology is redefining the savings-to-spending cycle. Traditional banks are responding by investing heavily in digital infrastructure or launching separate online brands.
