You probably paid at least five of these companies this week without thinking about it. You ordered something on Amazon, picked up groceries at Walmart or Kroger, filled up at a Chevron or Exxon pump, scrolled Instagram, paid your phone bill to Verizon or AT&T. That’s how big they are. They are in your morning, your bank account and your medicine cabinet.
But when you search “top 100 companies in USA” you get a mess. One site ranks by revenue, another by stock market value, and some are still showing Walmart at #1 even though that changed in June 2026. Some show only 10 names and ask you to pay for the rest.
So here is the full list in one place. We ranked the 100 biggest publicly traded US companies by revenue for fiscal 2025, using the 2026 Fortune 500 numbers. You get the ticker, sector, headquarters and number of employees for each one. Then we show you the top 10 by market value, what changed this year, which states and industries own the list, the giant private companies you can’t buy shares in, and how you can own most of this list with one fund.
The Top 10 at a Glance
| # | Company | Ticker | Revenue (FY2025) | What they do |
|---|---|---|---|---|
| 1 | Amazon | AMZN | $716.9B | Online store, AWS cloud, Prime |
| 2 | Walmart | WMT | $713.2B | Stores, Sam’s Club, online grocery |
| 3 | UnitedHealth Group | UNH | $447.6B | Health insurance and Optum clinics |
| 4 | Apple | AAPL | $416.2B | iPhone, Mac, App Store, services |
| 5 | Alphabet | GOOGL | $402.8B | Google Search, YouTube, Google Cloud |
| 6 | CVS Health | CVS | $402.1B | Pharmacies, Aetna insurance |
| 7 | Berkshire Hathaway | BRK.B | $371.4B | GEICO, BNSF railroad, energy, stock holdings |
| 8 | McKesson | MCK | $359.1B | Ships medicine to pharmacies and hospitals |
| 9 | Exxon Mobil | XOM | $332.2B | Oil, gas and chemicals |
| 10 | Cencora | COR | $321.3B | Drug wholesaler (used to be AmerisourceBergen) |
Each of the top 10 made more than $320 billion, and together they brought in $4.5 trillion.
How This List Is Ranked (and Why Your #1 Depends on It)
There are four common ways to rank a company, and each one gives you a different winner.
- Revenue (sales): Amazon is #1 with $716.9 billion. This is what Fortune uses and it’s what this list uses.
- Market cap (what the stock market says the company is worth): Apple is #1 at $5.06 trillion on 10 November 2026. Nvidia was ahead of Apple earlier in the year, so this one flips around.
- Profit: Alphabet was the most profitable company on the 2026 Fortune 500, with a record $132 billion.
- Employees: Walmart, with about 2.1 million people. Amazon is second with about 1.58 million.
That’s why Nvidia is #16 here even though it’s the second most valuable company in the country. It sells fewer dollars of stuff than CVS or McKesson, but investors pay a lot more for each dollar it earns. McKesson is the reverse. It moves $359 billion of medicine a year, but on thin margins, so you won’t find it anywhere near the market cap top 10.
If you are an investor, market cap and profit matter more to you. If you are looking for a job or want to know who really runs the economy, revenue and employees tell you more. We give you both below.

The Top 25, Company by Company
Most people know Apple and Ford. Fewer can tell you what Cencora or Centene do, even though they are bigger than Ford. Here’s a quick look at the top 25.
1. Amazon (AMZN)
Amazon finally took the #1 spot in 2026 with $716.9 billion in revenue, ending Walmart’s 13-year run at the top. It got there with its online store, third-party seller fees, Prime subscriptions, ads and Amazon Web Services, the cloud business that runs a big chunk of the internet. It also employs about 1.58 million people.
2. Walmart (WMT)
Walmart missed first place by about $3.8 billion, which is close to a rounding error at this size. This is the first time since 2012 that Walmart is not #1. It is still the biggest private employer in the country with around 2.1 million workers, and it owns Sam’s Club too.
3. UnitedHealth Group (UNH)
The largest health insurer in the US. UnitedHealthcare sells the insurance plans, and its Optum side runs doctor groups, clinics and the pharmacy benefits business. Revenue was $447.6 billion. If your insurance card says UnitedHealthcare, a slice of your premium shows up in this number.
4. Apple (AAPL)
$416.2 billion in revenue, most of it from the iPhone, plus Macs, iPads, the Watch and a fast-growing services business (App Store, iCloud, Apple Music). Apple is the most valuable company in the US by market cap at $5.06 trillion on 10 November 2026.
5. Alphabet (GOOGL)
Google’s parent moved up two spots to #5. It made $402.8 billion from search ads, YouTube and Google Cloud, and it earned a record $132 billion in profit, more than any other company on the Fortune 500.
6. CVS Health (CVS)
You know the drugstores. What you might not know is that CVS also owns Aetna, the health insurer, and Caremark, one of the biggest pharmacy benefit managers. That mix took revenue to $402.1 billion.
7. Berkshire Hathaway (BRK.B)
Warren Buffett’s company owns GEICO, the BNSF railroad, Berkshire Hathaway Energy, Dairy Queen and dozens of other businesses, plus a huge stock portfolio. Revenue was $371.4 billion. Greg Abel took over as CEO from Buffett at the start of 2026.
8. McKesson (MCK)
McKesson buys medicine from drug makers and delivers it to pharmacies, hospitals and clinics. It’s the biggest drug distributor in the country, with $359.1 billion in revenue and only about 44,000 employees.
9. Exxon Mobil (XOM)
The largest US oil company, with $332.2 billion in revenue from oil and gas production, refining and chemicals. Exxon moved its headquarters from Irving to its Spring, Texas campus near Houston.
10. Cencora (COR)
Another drug wholesaler, formerly called AmerisourceBergen. It changed its name in 2023. Revenue was $321.3 billion, based in Conshohocken, Pennsylvania.
11. Microsoft (MSFT)
Windows, Office, Xbox, LinkedIn and, most of all, the Azure cloud. Revenue was $281.7 billion. Microsoft is the third most valuable US company at $3.96 trillion.
12. JPMorgan Chase (JPM)
The biggest bank in the US, with $280.4 billion in revenue and around 319,000 employees. It runs Chase consumer banking, credit cards, investment banking and asset management. You can read more in our list of top 15 banking stocks in the USA.
13. Costco Wholesale (COST)
The membership warehouse store made $275.2 billion. A big part of its profit comes from membership fees, not from the hot dog combo that has cost $1.50 since 1985.
14. Cigna Group (CI)
A health insurer that also owns Express Scripts, a pharmacy benefit manager. Revenue was $274.9 billion.
15. Cardinal Health (CAH)
The third big drug distributor on this list, plus a medical supplies business. Revenue was $222.6 billion, headquartered in Dublin, Ohio. McKesson, Cencora and Cardinal Health together moved more than $900 billion of products in a year.
16. Nvidia (NVDA)
Nvidia makes the chips that train and run most AI models. Revenue was $215.9 billion, which puts it at #16, but it became the first $4 trillion company on the Fortune 500 and it is the second most valuable US company today at $4.07 trillion.
17. Meta Platforms (META)
Facebook, Instagram, WhatsApp and Threads. Almost all of its $201 billion in revenue comes from ads.
18. Elevance Health (ELV)
Formerly Anthem. It runs Blue Cross Blue Shield plans in 14 states and Medicaid plans in others. Revenue was $199.1 billion.
19. Centene (CNC)
The biggest Medicaid insurer in the country and a big seller of Affordable Care Act marketplace plans. Revenue was $194.8 billion, based in St. Louis.
20. Bank of America (BAC)
The second largest US bank, with $191.6 billion in revenue and Merrill Lynch under the same roof.
21. Chevron (CVX)
The second biggest US oil company, at $189.0 billion. It moved its headquarters from California to Houston.
22. Ford Motor (F)
$187.3 billion in revenue. The F-Series pickup has been the best-selling truck in America for decades.
23. General Motors (GM)
Chevrolet, GMC, Cadillac and Buick brought in $185.0 billion.
24. Citigroup (C)
The third largest US bank, at $168.3 billion, with the biggest overseas presence of the big US banks.
25. Home Depot (HD)
The biggest home improvement retailer, with $164.7 billion in revenue and about 472,000 employees. Lowe’s, its main rival, is #51.
What Changed in 2026
The 2026 Fortune 500 came out on 3 June 2026 and a lot moved.
- Amazon passed Walmart. First time Walmart is not #1 since 2012.
- Alphabet climbed two spots to #5 and posted the biggest profit of any company, $132 billion.
- Nvidia hit $4 trillion, the first Fortune 500 company to do it, and passed Apple as the most valuable company at the time the list came out.
- Carvana jumped 94 spots to #220 after its revenue grew 49%. Biggest climb on the list.
- 12 companies joined for the first time, including Galaxy Digital (#76 on Fortune’s list, #72 here), Medline (#159), Amentum (#313), Venture Global (#328) and Arista Networks (#444).
- The bar went up. You needed $7.5 billion in revenue to make the Fortune 500, 5% more than last year.
- The whole 500 made $21.0 trillion in revenue (up 5%) and $2.1 trillion in profit (up 12%), is worth $55 trillion (up 19%) and employs 30.5 million people.
- 55 companies, or 11%, have a woman CEO.
Then there’s SpaceX. Elon Musk’s rocket and Starlink company went public on Nasdaq on 12 June 2026 under the ticker SPCX. It priced at $135 a share, a $1.77 trillion valuation, the biggest IPO ever, and closed its first day at $161. Its revenue is too small for the top 100 by sales (Forbes estimated about $13 billion when it was still private), but by market value it’s #6 in the country right now.
Top 10 Most Valuable US Companies by Market Cap
Market cap is share price times the number of shares. These numbers are from the close on 10 November 2026 and they change every trading day.
| # | Company | Ticker | Market cap | Revenue rank |
|---|---|---|---|---|
| 1 | Apple | AAPL | $5.06T | 4 |
| 2 | Nvidia | NVDA | $4.07T | 16 |
| 3 | Microsoft | MSFT | $3.96T | 11 |
| 4 | Alphabet | GOOGL | $3.53T | 5 |
| 5 | Amazon | AMZN | $2.93T | 1 |
| 6 | SpaceX | SPCX | $1.94T | Not on the list |
| 7 | Meta Platforms | META | $1.64T | 17 |
| 8 | Broadcom | AVGO | $1.58T | 67 |
| 9 | Tesla | TSLA | $1.50T | 42 |
| 10 | Eli Lilly | LLY | $1.28T | 65 |
Just outside the top 10 sit Berkshire Hathaway ($1.24T), Walmart ($996B), JPMorgan Chase ($908B), AMD ($845B) and Micron ($820B).
Look at the last column. Only Amazon, Apple, Alphabet and Microsoft are in the top 11 for both revenue and value. Broadcom, Tesla and Eli Lilly are worth over $1 trillion each while ranking in the 40s and 60s on sales. Investors are paying for the growth they expect, AI chips at Broadcom, robotaxis and robots at Tesla, weight loss drugs like Zepbound and Mounjaro at Lilly.
Top 100 US Companies by Sector
We grouped the 100 companies into 10 sectors. Here’s how they split.
| Sector | Companies | Combined revenue |
|---|---|---|
| Health care (insurers, drug distributors, pharma, hospitals) | 19 | $3.16T |
| Finance (banks, insurers, Berkshire, Fannie Mae, Freddie Mac) | 18 | $2.36T |
| Retail (incl. Amazon) | 9 | $2.35T |
| Tech (hardware, software, chips, internet) | 15 | $2.14T |
| Energy (oil, refining, pipelines) | 9 | $1.15T |
| Telecom and media | 6 | $0.58T |
| Food, drinks and consumer goods | 8 | $0.55T |
| Autos | 3 | $0.47T |
| Aerospace and industrial | 7 | $0.47T |
| Transport (airlines, UPS, FedEx, Uber) | 6 | $0.41T |
Health care is the biggest. Eight of the top 25 companies are health care companies, and together the 19 on this list made over $3 trillion. Most of that money is passing through: an insurer collects premiums and pays them out to hospitals, and a drug wholesaler buys pills and sells them on. That’s why these companies have huge revenue and fairly small profits.
On the full Fortune 500, finance has the most companies (95, with $4.1 trillion in revenue), then energy (61), tech (53), health care (47) and retail (41). If you want to dig into one sector, see our lists of top 15 industrial stocks in the USA, top 10 construction stocks and top clothing stocks.
Which States Have the Most Top 100 Companies?
California and Texas tie with 16 companies each in the top 100. New York has 13, then Ohio, Virginia and Illinois with 6 each.
- California (16): Apple, Alphabet, Nvidia, Meta, Wells Fargo, Disney, Broadcom, TD Synnex, Cisco, HP, Intel, Ingram Micro, Uber, Molina Healthcare, Netflix, Qualcomm. Mostly tech, mostly in the Bay Area.
- Texas (16): McKesson, Exxon Mobil, Chevron, Phillips 66, AT&T, Valero, Dell, Tesla, Energy Transfer, Sysco, Caterpillar, ConocoPhillips, Oracle, American Airlines, Enterprise Products, Plains GP. Lots of oil and gas, plus companies that moved in from California (Tesla, Oracle) and Illinois (Caterpillar).
- New York (13): JPMorgan, Citigroup, Goldman Sachs, Morgan Stanley, Verizon, American Express, MetLife, Pfizer, IBM, PepsiCo, StoneX, Galaxy Digital, Travelers. Mostly Wall Street.
Across the whole Fortune 500, Texas leads with 57 headquarters, California has 56 and New York 53. The 500 are spread over 229 cities in 39 states.
The Biggest Private Companies in the US
Some huge American companies don’t sell shares, so they don’t show up on stock lists. Here are the 10 largest, from Forbes’ December 2025 list of America’s top private companies.
| # | Company | Revenue | What they do |
|---|---|---|---|
| 1 | Cargill | $154B | Grain, meat, food ingredients (Minnesota) |
| 2 | Koch | $125B | Pipelines, refining, chemicals, paper cups and more |
| 3 | Publix Super Markets | $59.7B | Supermarkets, owned by its employees |
| 4 | Mars | $55B | M&M’s, Snickers, pet food and vet clinics |
| 5 | H-E-B | $49.6B | Supermarkets in Texas and Mexico |
| 6 | Reyes Holdings | $44B | Beer and food distribution |
| 7 | Enterprise Mobility | $38B | Enterprise, National and Alamo car rental |
| 8 | Fidelity Investments | $32.7B | Brokerage, 401(k) plans, mutual funds |
| 9 | Southern Glazer’s Wine & Spirits | $25B | Alcohol distribution |
| 10 | Cox Enterprises | $23.5B | Cable and internet, Cox Automotive |
Cargill would rank around #27 on our main list, between Fannie Mae and Kroger. Koch would sit in the mid 30s. You can’t buy either one. Publix is a special case: it files with the SEC and shows up on Fortune’s list, but only employees and a few others can own the stock.
How to Invest in the Top 100 US Companies
You don’t need to buy 100 stocks. Almost all of these companies are in the S&P 500, so one S&P 500 index fund gets you most of this list at once.
- Vanguard S&P 500 ETF (VOO): 0.03% a year in fees
- iShares Core S&P 500 ETF (IVV): 0.03%
- SPDR S&P 500 ETF Trust (SPY): 0.0945%, the oldest and most traded
With a 0.03% fee you pay $3 a year on every $10,000 you invest. The fund weights by market cap, so Apple, Nvidia and Microsoft make up a much bigger share of your money than McKesson or Kroger.
A few names on this list are not in the S&P 500. Fannie Mae and Freddie Mac have traded over the counter since 2010 under government conservatorship, and there have been plans to relist them, so check their status before you buy. Energy Transfer and Enterprise Products Partners are pipeline partnerships, which the index leaves out, and they send you a K-1 tax form instead of a 1099. Plains GP Holdings is not in the index either. Newer listings like Galaxy Digital and SpaceX may not be in the index yet, so check before you assume your fund owns them.
If you’d rather pick, start with the ones you already use and understand. Compare a few on revenue growth, profit and price to earnings, and read the latest quarterly report.

Frequently Asked Questions
What is the biggest company in the USA?
By revenue, Amazon, with $716.9 billion in fiscal 2025. It passed Walmart ($713.2 billion) on the 2026 Fortune 500. By market value, Apple, at $5.06 trillion on 10 November 2026. By employees, Walmart, with about 2.1 million.
Is the Fortune 100 the same as the top 100 US companies?
Close, but not exactly. The Fortune 100 is the first 100 companies on the Fortune 500, ranked by revenue. It includes mutual insurers like State Farm and New York Life and employee-owned Publix, which you can’t buy on a stock exchange. Our list only includes publicly traded companies, so a handful of names differ.
Which is bigger, Amazon or Walmart?
Amazon, by a little. Amazon made $716.9 billion and Walmart $713.2 billion in fiscal 2025. Walmart has far more employees, about 2.1 million against Amazon’s 1.58 million. On market value Amazon is much bigger, $2.93 trillion against Walmart’s $996 billion.
What is the most valuable company in the US right now?
Apple, at $5.06 trillion at the close on 10 November 2026, ahead of Nvidia at $4.07 trillion. These two have traded places more than once in 2026, so check a live quote.
Which state has the most big companies?
Texas has the most Fortune 500 headquarters (57), just ahead of California (56) and New York (53). In our top 100, California and Texas tie at 16 each.

Cargill, the Minnesota food and agriculture company, with about $154 billion in revenue, according to Forbes. Koch is second at $125 billion.
How much revenue does a company need to make the Fortune 500?
$7.5 billion for the 2026 list, up 5% from the year before. To make our top 100 you needed about $44 billion. Qualcomm is #100 at $44.3 billion.
Can I invest in all of the top 100 US companies at once?
Almost. An S&P 500 index fund like VOO, IVV or SPY holds nearly all of them. The ones it misses are Fannie Mae, Freddie Mac, the pipeline partnerships and some newer listings.
