When you think of the Midwest, you probably picture cornfields or maybe the Chicago skyline. But honestly, if you're looking for where the actual money is moving, you've gotta look at the "Queen City." Cincinnati isn't just a river town with a weird obsession with chili on spaghetti. It's a massive corporate engine.
It’s kinda wild.
A lot of people assume the largest companies in Cincinnati are just a few old manufacturing plants. Wrong. We are talking about global titans that literally dictate what you wash your hair with and how you buy your groceries. In 2026, the local economy is a bizarre, fascinating mix of "old school" Fortune 500s and a healthcare sector that has basically become its own zip code.
The Retail King in Your Backyard
Let's start with the obvious one. Kroger.
Basically everyone knows the name, but most don't realize that The Kroger Co. is a legitimate behemoth. Headquartered right on Vine Street, they are doing roughly $150 billion in annual revenue. That’s not a typo. They aren’t just a grocery store anymore. They’re a tech company that happens to sell milk.
They’ve got over 414,000 employees globally, though a huge chunk of that brainpower stays right here in the Cincy region. Recently, their massive push into automated fulfillment centers—those giant "sheds" where robots pick your groceries—has changed the game. If you've ever used their delivery app, you’re interacting with tech built by people sitting in downtown Cincinnati offices.
The "Invisible" Giant: Procter & Gamble
Then there’s P&G.

If Kroger is the king of the shelf, Procter & Gamble is the king of the products on the shelf. You’ve probably got five of their products in your bathroom right now. Tide, Crest, Pampers—it’s all P&G. They’ve been here since 1837. Back then, it was just two brothers-in-law making candles and soap.
Now? They’re pulling in over $84 billion a year.
What's cool about P&G isn't just the money, though. It’s the talent magnet effect. They employ around 12,000 people locally. Because they’re so big, they’ve basically turned Cincinnati into a "branding" capital. Half the marketing agencies in the city exist because P&G is here. It’s a ripple effect that most people don't see from the outside.
Why Healthcare is Taking Over
Honestly, if you ask a local who the biggest employer is, they might not say a retail brand. They’ll say a hospital.
Cincinnati Children’s Hospital Medical Center is a beast.
In early 2025, Forbes ranked them as the #1 best large employer in Ohio. They have nearly 20,000 employees. It’s a city within a city. You go to the Burnet Avenue campus and it’s just endless buildings and specialized research centers. They handle over 1.6 million patient encounters a year.
But it’s not just about size. It’s about the fact that they draw people from all over the world. It’s a massive economic driver that doesn't rely on selling "stuff" but on providing specialized, high-tier care. When you add in TriHealth and UC Health, the medical sector is arguably the most stable part of the local job market.

The Financial Powerhouses
You can't talk about the largest companies in Cincinnati without mentioning the banks and insurance firms.
- Fifth Third Bank: They’re a regional powerhouse with over $200 billion in assets. Their headquarters at Fountain Square is an icon of the city.
- Western & Southern Financial Group: These guys own the Great American Tower—the building with the "tiara" on top. They manage over $120 billion in assets.
- American Financial Group: A specialized insurance giant that’s been a staple for decades.
It’s a lot of suits. But these companies provide the capital that keeps the rest of the city growing. They are the reason the skyline looks the way it does.
The Uniform King: Cintas
Ever wonder who provides those floor mats at your local gym or the uniforms at the mechanic? It’s probably Cintas.
They are technically headquartered in Mason, just a short drive north of the city limits, but they are intrinsically tied to the Cincinnati economy. They’ve got about 48,000 employees and pull in over $10 billion. They’ve been on a tear lately, recently moving to acquire competitors and solidifying their spot as the "undisputed heavyweights" of corporate services.
The Reality of the "Big Seven"
If you’re looking at the pure numbers, the Fortune 500 list for Cincinnati usually hovers around seven to eight companies.
| Company | Main Industry |
|---|---|
| Kroger | Retail / Grocery |
| Procter & Gamble | Consumer Goods |
| GE Aerospace | Aviation / Tech |
| Fifth Third Bancorp | Finance |
| Western & Southern | Insurance |
| Cintas | Business Services |
| American Financial Group | Insurance |
GE Aerospace is another one that confuses people. They’re technically based in Evendale. But they are a massive part of the region's identity. They make the engines that power half the planes you fly on. When GE split into three separate companies, the aerospace division—the "crown jewel"—stayed right here.
What This Means for You
If you're moving here or looking for a career change, don't just look at the names. Look at the industries. Cincinnati is weirdly resilient because it isn't a one-trick pony. It’s not just "tech" like San Francisco or "finance" like Charlotte. It’s a mix of food, health, soap, and jet engines.
That diversity is why the city doesn't crash as hard during recessions. People still need to eat (Kroger), wash their clothes (P&G), and go to the doctor (Children's).
If you want to dive deeper into the Cincinnati business scene, your best bet is to follow the Cincinnati Business Courier. They keep a running "Book of Lists" that tracks the exact employee counts for every firm in the metro area. You can also check out REDI Cincinnati, which is the economic development group that helps these companies expand. They have some of the most up-to-date data on who is hiring and who is building new facilities in the 2026-2027 pipeline.
Keep an eye on the riverfront development too. A lot of these big players are pouring money into the "Banks" area between the stadiums. It’s not just about offices anymore; it’s about creating a "live-work-play" environment to attract the next generation of talent that these giants desperately need.
Start by looking into the "Innovation District" near the University of Cincinnati. That’s where the big corporate money is meeting the startup world. It's the best place to see how these legacy giants are trying to stay relevant in a tech-heavy future. You’ll find research outposts for Kroger and P&G right next to student labs. It’s the future of the city’s economy in one city block.
