## What technology stack does U.S. Bank run its AI on?

U.S. Bank's stack is a reusable digital platform being moved to public cloud, with an in-house agentic layer on top. CFO John Stern said in September 2025 that technology investment runs at about $2.5 billion a year and that the priorities are 'simple architecture', using the cloud to help the mainframe and hollow out the core, product development, and reusability, which he called a differentiator. In May 2026 the bank agreed a multiyear move of hundreds of mission-critical applications to AWS, with Amazon Bedrock, Nova Sonic and Connect Customer as the base for generative AI and agents. Chief digital officer Dominic Venturo built an enterprise platform that is 80% reusable, so teams ship in months, and the Developer Portal, created in 2019, serves billions of API requests and now has a GenAI Developer Assistant. CIO Dilip Venkatachari says in-house agentic software underpins the early AI use cases, and in October 2026 described a federated model with shared guardrails and an internal AI marketplace. Engineers use GitHub Copilot, Cognition and Claude Code, and a GenAI code-review assistant cuts review time by 75%. Cloud split, data platform vendor and engineering headcount are not disclosed.

## Where does U.S. Bank already run machine learning in operations?

Treasury and payments teams combine machine learning with optical character recognition to digitise business clients' signatory information and improve sanctions screening, according to a U.S. Bank treasury insights article. ([U.S. Bank](https://usbank.com/corporate-and-commercial-banking/insights/payments-hub/trends/treasury-management-ai.html))

STAT reads inconsistent merchant statements with vision AI for Elavon sales reps, and the 2025 10-K names algorithmic bias, explainability and flawed datasets as risks of models built on AI or machine learning.

## Common questions

### Is U.S. Bank moving to the cloud?

Yes. In May 2026 U.S. Bank announced a multiyear agreement to move hundreds of mission-critical applications to Amazon Web Services and to use Amazon Bedrock, Nova Sonic and Connect Customer for generative AI and AI agents. CFO John Stern had said in 2025 that the bank uses the cloud to help the mainframe and hollow out the core.

### How much does U.S. Bank invest in technology?

About $2.5 billion a year, CFO John Stern said at the Barclays conference in September 2025, split roughly two-thirds on offense, such as new products, and one-third on defense, such as maintenance. CEO Gunjan Kedia added that the bank invests further operating expense in sales, marketing and partnerships.

### What is U.S. Bank's internal AI marketplace?

CIO Dilip Venkatachari described it in October 2026 as part of moving AI from a prove-it to a scale-it phase: a common platform with shared services and guardrails where teams can find and reuse each other's AI tools, so the first use case may take a village but the tenth should take an afternoon.

### What coding tools do U.S. Bank engineers use?

Engineers started on GitHub Copilot and now also have Cognition and Claude Code, Chief AI Officer Prashant Mehrotra said in July 2026. The 2025 annual report says a GenAI-powered code-review assistant cuts review time by 75%, and the CIO said 70% to 75% of engineers were trained and using AI tools within three months.
