Sells core account processing, digital banking, card issuing and payments to banks and credit unions under multi-year contracts, and since May 2026 has sold AI on top of that installed base through agentOS, a governed agent platform built with OpenAI and AWS.
What is Fiserv, and which banks use it?
Fiserv (Nasdaq: FISV), the Milwaukee core and payments processor formed in 1984, launched agentOS in May 2026. It is a platform for AI agents that run on its cores, built with OpenAI and AWS. First Interstate Bank is piloting its commercial-loan onboarding agent. Bank OZK and SouthState are co-developing the next agents. Pricing is not published. Fiserv charges account- and transaction-based fees, and says agentOS agents are paid for with credits (per query, per outcome or by subscription), with no figures given.

- agentOS launched on May 14, 2026 with four Fiserv-built agents (Commercial Loan Onboarding, Daily Operational Analysis and Reporting, Agentic Deposit Intelligence and Agentic AML Triage Analysis) and nine third-party agents. At launch two institutions were running agents in beta, and Fiserv expected wide availability by August 2026.
- Fiserv said six financial institutions were co-developing agentOS. First Interstate Bank and Boulder Dam Credit Union were running pilots, and Salem Five, City National Bank, Bank OZK and SouthState were co-developing the next agents, with deployments due to start in summer 2026.
- On its August 6, 2026 earnings call, Fiserv said the number of financial institutions interested in agentOS had grown to more than 100 since the launch. Two institutions were named as running pilots at launch.
- The AI runs on outside models. agentOS uses Amazon Bedrock AgentCore, Fiserv builds some of its own agents with OpenAI, and Fiserv also uses Microsoft 365 Copilot, Microsoft Foundry, GitHub Copilot and Cognition's Devin across its own workforce and engineering.
- Fiserv is in a turnaround. Its stock fell 44% on October 29, 2025 after it cut its 2025 outlook. CEO Mike Lyons left in June 2026 to run Truist. Co-President and later President Dhivya Suryadevara, who helped lead agentOS, resigned in July 2026. Second-quarter 2026 revenue fell 4%, with Financial Solutions down 8% on an organic basis.
- Pricing is not published. Fiserv's 10-K says processing and services revenue (80% of 2025 revenue) comes mainly from account- and transaction-based fees under multi-year contracts. The agentOS page describes credits spent per query, per outcome or by subscription, but gives no prices.
- American Banker reported in May 2026 that Fiserv has about 6,000 financial-institution customers, 3,000 of which use its core systems, so agentOS is sold to an existing installed base rather than to new logos.

How much does Fiserv cost?
How it is charged: Account- and transaction-based fees under multi-year platform contracts; agentOS agents bought with credits spent per query, per outcome or by subscription (no figures)..
Fiserv does not publish a price list.
- Fiserv's 2025 Form 10-K says processing and services revenue, 80% of its $21.2 billion 2025 total revenue, is primarily generated from account- and transaction-based fees under multi-year contracts that generally have high renewal rates. This is Fiserv's own disclosure of its revenue model, not a price for its AI products. (Dec 31, 2025)[7]
Pricing is not published. Fiserv's agentOS page describes buying credits and spending them across agents, each priced per query, per outcome or by subscription, with a sandbox to test before paying, but it states no prices. Platform contracts are account- and transaction-based and negotiated with each institution.

What is agentOS?
An agentic AI operating system launched on May 14, 2026 that runs natively across Fiserv's core, payments, issuer-processing and servicing platforms. Banks can use Fiserv-built agents, build their own or deploy third-party agents from a marketplace, under shared identity, policy, audit and kill-switch controls. It runs on Amazon Bedrock AgentCore, and Fiserv builds some of its own agents with OpenAI. At launch two institutions were running agents in beta, and Fiserv expected wide availability by August 2026.[1][2][4]

Which rules apply to a bank using Fiserv?
| Authority | Why it matters here | Documents |
|---|---|---|
| OCC | For an OCC-supervised bank, agentOS agents that read from and write to its Fiserv core are both a third-party relationship with its most critical provider and vendor models. OCC Bulletin 2023-17 due diligence and 2026-13 model-risk expectations apply to each agent the bank turns on. | OCC Bulletin 2023-17 OCC Bulletin 2026-13 |
| Federal Reserve | A state member bank using Fiserv-built or partner agents must manage them under SR 23-4. Its due diligence should reach the model providers beneath Fiserv (OpenAI, Amazon Bedrock) and the machine-learning components validated under SR 26-2. | SR 23-4 SR 26-2 |
| FDIC | State non-member banks fall under the FDIC's copy of the interagency third-party guidance when they add AI agents to a Fiserv core contract. | FDIC FIL-29-2023 |
| FinCEN | A bank that uses Fiserv's Agentic AML Triage Analysis agent still owns its BSA/AML program outcomes. FinCEN's 2026 AML/CFT program proposal frames how automated triage fits into a risk-based program. | 2026 AML/CFT Program Proposed Rule |

What should a bank note before buying Fiserv?
Analysis by BankingNewsAI from the sources cited on this page. Observations, not advice or a recommendation.
01
Most agentOS evidence is announcements, not production
At launch two institutions were running agents in beta (one bank in our set, First Interstate, and one credit union). Four others were co-developing, and Fiserv reported interest from more than 100 institutions. We found no public source confirming that agentOS reached wide availability in August 2026 as targeted.
02
Pricing is not published
Fiserv's own agentOS page describes a credit model (per query, per outcome or subscription) without figures. Its filings describe account- and transaction-based platform fees but give no price for AI features.
03
Results are customer or vendor statements
The only quantified agentOS result, report times cut from 10 minutes to seconds, is a credit union CEO's statement in Fiserv's own release. First Interstate reports reduced data entry and cycle times without figures.
04
Leadership changed after the launch
Within two months of launching agentOS, Fiserv changed CEOs, and the president who had helped lead agentOS resigned. Interim co-heads now run Financial Solutions, the unit that sells it.
05
The AI sits on several outside providers
agentOS uses Amazon Bedrock AgentCore and OpenAI-built agents, and Fiserv's engineering uses Microsoft and Cognition tools. A bank's third-party review of an agent covers that chain, not only Fiserv.

How much does Fiserv agentOS cost?
Fiserv does not publish prices. Its agentOS page says institutions buy credits and spend them across agents, each priced per query, per outcome or by subscription, and can test an agent on their own data in a sandbox before paying. No figures are given. Fiserv's 10-K says its platform revenue comes mainly from account- and transaction-based fees under multi-year contracts, so AI features are negotiated as part of each institution's contract.
Which banks use Fiserv's AI agents?
Among the 100 largest US banks tracked here, First Interstate Bank is piloting Fiserv's Commercial Loan Onboarding Agent, co-created with Fiserv, according to Fiserv's May 2026 launch release and American Banker. Bank OZK and SouthState are named as co-developing the next agents, with deployments due to start in summer 2026. Fiserv also names Salem Five, City National Bank and Boulder Dam Credit Union.
Who owns Fiserv?
Fiserv is a public company. Since November 2025 it has traded on Nasdaq as FISV, after moving from the New York Stock Exchange, where it traded as FI. It is headquartered in Milwaukee, Wisconsin, and was formed in 1984. Takis Georgakopoulos has been CEO since June 2026, succeeding Mike Lyons, who left to run Truist.
What AI models does Fiserv agentOS use?
Fiserv says agentOS runs on Amazon Bedrock AgentCore, which gives access to several AI models. Fiserv is building some of its own agents with OpenAI. The agentOS page describes routing each task across general models and specialized small language models. Nine third-party companies, including Sardine, Sierra and Trulioo, had signed up to provide agents at launch, per American Banker.
Is Fiserv agentOS generally available?
At its May 14, 2026 launch, Fiserv said two institutions were running agents in beta and that it expected wide availability by August 2026. On its August 6, 2026 call it said interest had grown to more than 100 institutions. We found no public Fiserv source confirming general availability, and the product page still marks agent-building by banks as coming soon.
Is Fiserv a bank or regulated like one?
No. Fiserv is a technology and payments company, not a chartered bank. Banks that use its core systems and AI agents must oversee it as a critical third party under the banking agencies' third-party risk guidance. They must also bring its models under their model-risk management programmes, since the agents act on the bank's own core data.
How does Fiserv's AI compare with FIS's?
Fiserv built agentOS with OpenAI on Amazon Bedrock, and American Banker reported in May 2026 that FIS had built a financial-crimes agent with Anthropic. Fiserv's distinguishing feature is a marketplace of first- and third-party agents under one set of controls. Its evidence so far is two beta pilots and interest from more than 100 institutions.
