Advancing how the world pays, banks and invests - software that runs quietly behind more than 20,000 financial institutions.
FIS is one of the largest financial technology companies most people have never heard of. When a paycheck lands, a debit card clears, a fraud alert fires or a trade settles, there is a reasonable chance a Fidelity National Information Services system was somewhere in the chain. The company sells the software and processing that banks, credit unions, lenders, asset managers and corporates depend on - and it does so almost entirely out of view of the consumers those institutions serve.
Headquartered in Jacksonville, Florida, and traded on the New York Stock Exchange under the ticker FIS, the company organizes its sprawling product line around a single, unusually clear idea: money exists in three states - at rest (deposits and accounts), in motion (payments and transfers) and at work (investing and capital markets). FIS builds technology for all three.
That breadth is the point. A regional bank can license a core banking platform, add card issuing and fraud tools, and plug into real-time payment rails without building any of it in-house. An asset manager can run trading, custody and treasury software from the same vendor. FIS turns dense, regulated financial infrastructure into something institutions can actually buy and ship.
FIS serves more than 20,000 institutions in over 100 countries: global and money-center banks, US regional and community banks, credit unions, commercial lenders, asset managers, custodians, treasurers, clearing agents, corporates and developers. Its customers share a common problem - modern finance demands software that is reliable, secure, compliant and always on, but building that software from scratch is prohibitively expensive.
Community banks and credit unions need the same digital experience customers get from a megabank. Shared FIS core platforms give them modern tools at a scale they could never build alone.
Cards, transfers and real-time payments must clear 24/7 across borders and networks. FIS runs the processing and money-movement rails that keep transactions flowing.
Every transaction is a potential attack surface. FIS layers real-time fraud detection, compliance and risk tooling on top of the payments and banking flows it powers.
Asset managers, custodians and treasurers juggle trading, settlement and reporting. FIS provides the specialized software - much of it inherited from its 2015 SunGard acquisition.
The FIS catalog is broad, but it maps cleanly onto those three states of money. Here is how the major pieces fit together.
Core processing and digital banking platforms that run deposit, loan and account systems for banks and credit unions of every size.
Card issuing, processing, electronic funds transfer and network services for institutions and merchants.
Account-to-account transfers and real-time payment rails connecting institutions and their customers.
Real-time fraud detection, compliance and risk analytics across payments and banking.
Trading, custody, treasury and clearing software for asset managers, traders and clearing agents.
Technology for wealth management and retirement providers.
An AI-powered banking capability built with Anthropic - described by FIS as a first in financial services, expected in market in the second half of 2026.
Software licenses, SaaS subscriptions and per-transaction processing fees under long-term institutional contracts.
After acquiring payments giant Worldpay for about $43B in 2019 and then divesting it between 2023 and 2025, FIS has refocused on banking and capital-markets technology. Recent revenue figures (approximate, per public reporting):
FIS competes in a market defined by scale, trust and switching costs. Core banking contracts run for years, and migrating off a platform is a major undertaking - which favors incumbents that can offer breadth across banking, payments and capital markets under one roof. Its chief rivals span several categories:
| Rival | Where they overlap with FIS |
|---|---|
| Fiserv | Core banking & payment processing for US financial institutions |
| Jack Henry & Associates | Core systems for community and regional banks |
| Global Payments | Merchant and card payment processing |
| Temenos / Finastra | Core banking software, especially internationally |
| Oracle Financial Services | Enterprise banking platforms |
| ACI Worldwide | Real-time and electronic payment systems |
FIS's edge is the combination of that breadth with deep incumbency: many institutions already run one FIS system, making it easier to add another. Its 2026 move into AI-native banking tools, including the Anthropic partnership, is an attempt to keep that incumbency durable as the technology stack shifts.
