Wall Street’s Six Biggest Banks Escalate Generative AI Race

Generative AI has moved from pilot programs to core infrastructure at JPMorgan Chase, Goldman Sachs, Citigroup, Morgan Stanley, Bank of America and Wells Fargo. The banks are embedding models in research, trading, software development and customer service, reshaping workflows and staffing. Investors are watching whether the spending can deliver durable revenue growth, lower operating costs and stronger risk controls rather than merely adding another layer of expensive technology.

By August 2026, the six banks’ related technology budgets had reached the tens-of-billions-of-dollars range. JPMorgan, Goldman and Citi are expanding proprietary AI platforms and employee assistants, while Morgan Stanley is deepening its work with OpenAI. Bank of America and Wells Fargo are broadening digital-assistant capabilities. The next test is measurable productivity gains alongside safeguards against hallucinations, data leakage, biased outputs and regulatory breaches.
