Despite decades of innovation, Fintech firms have yet to disrupt the core banking model of deposits and loans, with major U.S. banks like JPMorgan, Bank of America, and Citi reporting strong profits and growing deposits. While Fintechs like SoFi and LendingClub gained traction, their deposit growth and credit card innovations pale compared to the massive lending and user bases of traditional banks. Fintechs are gaining ground in areas like small business lending, payments, and commercial cards but struggle to scale to the dominance of big banks, which have adapted well with mobile platforms. Coexistence may define the future.
