Large banks that have invested in artificial intelligence for years are beginning to see the real impact of the technology on their business operations and workforce.

Bank of America CEO Brian Moynihan told investors on Tuesday's Q2 2026 earnings call that more than 200,000 employees at the bank are using AI-enabled capabilities. Employees use AI-based productivity tools, coding assistants, and advanced agentic workflows, generating over 400,000 prompts daily.

As of last week, the banking giant had more than 300 approved AI use cases, including 114 generative AI use cases. Moynihan revealed that 34 of those approved AI use cases have been fully implemented in the bank's operations.

"These tools are designed to help our client relationship managers prepare more thoroughly for client meetings," Moynihan told investors on the call. "Our developers are coding more efficiently, and all team members can improve productivity, consistency, and client service levels while creating significant opportunities ahead of us."

Bank of America CFO Alastair Borthwick said the business is benefiting from strong financial advisor productivity driven largely by AI. Earlier this year, the bank's wealth management team launched an AI-driven tool for its financial advisors to better access Salesforce CRM data.

"AI-enabled tools are now more deeply embedded in the workflows of operations, risk, finance, technology, and client-facing teams," Borthwick said on the earnings call. "This helps reduce manual effort, increase speed, and enhance consistency in client and team member experiences."

AI-Driven Operations and Productivity Gains

Bank of America is not the only institution reporting operational changes and employee usage of AI tools. Wells Fargo launched AI Teammate earlier this week, and its CEO Charles Scharf noted that the company's AI investments are helping boost productivity.

Meanwhile, Citigroup CEO Jane Fraser said that as the company's transformation work nears completion, business leaders have been able to apply experience from large-scale technology implementations to integrating AI into banking processes and functions. Citi appointed Brian Saluzzo as chief information officer in March to help further scale AI adoption across the organization.

"Nearly 90% of our employees are using our AI tools," Fraser told investors on the bank's Q2 earnings call Tuesday. "This is not only driving productivity and client experience improvements, but also fueling growth and helping us significantly accelerate time-to-market."

At BNY Mellon, CEO Robin Vince said AI is creating value by increasing employee productivity, helping the bank build better products and client experiences, and bringing new capabilities to market through the bank's platforms and data.

Vince said on the bank's Q2 earnings call Wednesday that AI is becoming an important source of long-term value creation for the bank's clients, employees, and shareholders.

JPMorgan Chase CEO Jamie Dimon offered a slightly different perspective on AI's benefits during his investor discussions on Tuesday.

Dimon said on the Q2 earnings call that the bank has nearly 1,000 active AI use cases in areas such as risk, fraud, marketing document reading, and others. However, while he expects the technology to improve efficiency in certain parts of the company, Dimon said the biggest winners will be clients.

Dimon noted that AI is expensive, and as usage scales, he does not expect AI to boost the company's profit margins in the near term.

"You won't get unique benefits from AI," Dimon said. "The ultimate beneficiaries of AI will be our clients."
