Fiserv has introduced agentOS, a new operating system designed to help financial institutions deploy and manage agentic AI across banking operations in a secure and governed environment. Announced in New York City, the platform is expected to become broadly available by August 2026 and is already being co-developed with six financial institutions, with two banks currently running pilot programs.
The new platform is built to work directly across Fiserv’s banking ecosystem, including core banking, payments, issuer processing, and servicing systems. The company says agentOS is intended to help banks move beyond isolated AI experiments by offering enterprise-grade governance, auditability, and human oversight within AI workflows.
A key component of the launch is the introduction of the industry’s first banking-focused AI agent marketplace. The marketplace will initially feature four AI agents developed by Fiserv alongside nine third-party partner agents. These tools are designed to support functions such as anti-money laundering analysis, commercial loan onboarding, operational reporting, regulatory compliance, and reconciliation tasks.

“AI will fundamentally reshape how financial institutions operate,” said Dhivya Suryadevara, Co-President of Fiserv. “agentOS is the first place where banks can run Fiserv’s agents, build their own, and deploy from a curated set of partners all under the same governance, identity, and audit controls. The pilots are already proving it works delivering measurable gains today, with six financial institutions co-developing the next wave with us.”
Fiserv is also collaborating with OpenAI and Amazon Web Services to strengthen the platform’s AI capabilities. OpenAI is supporting the development of select first-party AI agents, while AWS is providing the infrastructure through Amazon Bedrock and AgentCore.
Early adopters are already reporting operational improvements. Boulder Dam Credit Union said its reporting processes have been reduced from minutes to seconds, while First Interstate Bank reported faster commercial loan onboarding through AI-driven automation.
The launch reflects a broader industry shift as banks increasingly seek practical, compliant ways to integrate AI into everyday operations while maintaining strict regulatory controls.
