Money talks.
But in the world of corporate giants, it doesn't just talk—it screams. If you’re looking at the largest companies in the united states by revenue, you might think it’s all Silicon Valley hoodies and AI startups. Honestly? You’d be wrong.
While Nvidia and Meta get all the "cool kid" press, the actual list of revenue titans is dominated by something much more grounded. We’re talking about groceries, pills, and the literal oil that keeps the gears turning. As of early 2026, the hierarchy is shifting in ways that would have seemed impossible five years ago.
The Battle for the Top Spot: Amazon vs. Walmart
For thirteen years, Walmart sat on the throne. It was the undisputed king of the hill. But we are living through a massive "changing of the guard" moment.
Analysts at Fiscal.ai and various market trackers have been holding their breath as Amazon finally closed the gap. In 2025, Amazon’s total revenue was projected to hit roughly $691.3 billion. Walmart, the brick-and-mortar behemoth from Bentonville, wasn't far behind with about $681 billion for its fiscal year.
It's a razor-thin margin.
What's wild is how they make that money. Walmart is essentially the world's biggest pantry. They move physical goods at a scale that defies logic. Amazon, however, is a weird hybrid. They sell you a toaster, sure, but they also own the digital "pipes" (AWS) that half the internet runs on.
Why Amazon is "Winning" (Even if the Gap is Small)
- Growth Rates: Amazon’s revenue has been growing at a compound annual rate of about 20% lately. Walmart? More like 4% to 5%.
- The Profitability Trap: Revenue is just the top line. It's the total cash coming in the door before you pay a single bill. Amazon’s AWS division generates massive profits that allow it to "subsidize" its retail side.
- The 13-Year Streak: Seeing Walmart potentially drop to #2 is like watching a record-breaking sports streak end. It feels weird.
The Healthcare Giants Nobody Talks About
You probably use an iPhone. You definitely buy stuff on Amazon. But you might not realize that UnitedHealth Group and CVS Health are basically the third and fifth largest companies in the country by revenue.

It's massive.
UnitedHealth Group is a monster. For the full year 2025, they reported a staggering $445.5 billion to $448 billion in revenue. Think about that for a second. That is more than the GDP of many medium-sized countries. They aren't just an insurance company; their Optum wing handles everything from pharmacy benefits to data analytics.
CVS Health is right there too. Most people think of the corner store where they buy snacks and prescriptions. In reality, CVS is a vertically integrated titan that brought in over $357 billion recently.
The 2026 Revenue Leaderboard (The Heavy Hitters)
If we look at the raw data from the most recent fiscal reports, the top of the mountain looks like this:
- Amazon: ~$691 Billion (Retail/Cloud)
- Walmart: ~$681 Billion (Retail)
- UnitedHealth Group: ~$447 Billion (Healthcare)
- Apple: ~$391 Billion (Technology)
- CVS Health: ~$373 Billion (Healthcare)
- Berkshire Hathaway: ~$371 Billion (Conglomerate)
- Alphabet (Google): ~$350 Billion (Technology)
- ExxonMobil: ~$345 Billion (Energy)
- McKesson: ~$309 Billion (Healthcare)
- Cencora: ~$294 Billion (Healthcare)
Notice something? Half of the top ten are healthcare or pharmacy-related.
The Tech Mirage
We often confuse "Market Cap" (what the stock market thinks a company is worth) with "Revenue" (how much money they actually collect).
Take Nvidia. In 2025, Nvidia became one of the most valuable companies in history because everyone is obsessed with AI chips. Their stock price went to the moon. But in terms of revenue? They brought in roughly $155 billion.

That's huge, obviously. But it’s less than half of what CVS Health brings in.
It’s a great reminder that the "real" economy—the stuff we eat, the medicine we take, and the cars we drive—still generates more raw cash flow than the speculative tech that dominates our news feeds. Meta (Facebook) sits even further down the list at about $164 billion. They are giants, but they aren't Walmart-sized giants.
What This Means for You
Why should you care about the largest companies in the united states by revenue? Because these companies are the weather makers.
When Walmart decides to raise its minimum wage, the entire retail sector feels the pressure to follow. When UnitedHealth Group changes its reimbursement policy, your doctor's office has to scramble. These firms have more influence over your daily life than most local governments do.
The "Squeeze" on Mid-Sized Players
The sheer scale of these companies creates a "gravity" effect. They can negotiate lower prices from suppliers, which lets them undercut smaller competitors. If you're a small pharmacy, competing with the purchasing power of a CVS or a Walgreens is basically a nightmare.
Investing Nuance
Just because a company has the highest revenue doesn't mean it's the best stock to buy. Revenue is "vanity," profit is "sanity," as the old saying goes.
Berkshire Hathaway, run by Warren Buffett, is a perfect example of a revenue giant that isn't just "selling stuff." They own GEICO, Dairy Queen, and massive railroads. Their revenue reflects the health of the entire American consumer.

The Road Ahead: Will We See a $1 Trillion Revenue Company?
It sounds fake. A trillion dollars?
But Amazon is on a trajectory to potentially hit that mark by the late 2020s or early 2030s if their cloud and advertising businesses continue to explode. We've seen trillion-dollar market caps for years, but a trillion-dollar revenue year is the final boss of capitalism.
One thing to watch is the impact of trade policies and tariffs. Companies like Apple and Ford have already warned that supply chain shifts could mess with their top-line numbers. If it gets more expensive to import parts, these revenue numbers might look "inflated" as companies pass costs to consumers, even if they aren't selling more units.
Actionable Takeaways for 2026
If you're tracking these giants, keep these three things in mind:
- Watch the "Healthcare 5": UnitedHealth, CVS, McKesson, Cencora, and Cardinal Health. They are the quiet rulers of the U.S. economy. As the population ages, their revenue is only going one direction: up.
- Revenue vs. Margin: Don't get blinded by big numbers. A company like Apple has "lower" revenue than Walmart but much higher profit margins. They keep more of every dollar they make.
- E-commerce is the Floor, Not the Ceiling: Walmart’s e-commerce growth (now over $100 billion) shows that the "old" companies are learning new tricks. The gap between digital and physical is disappearing.
The list of the largest companies in the united states by revenue is a living document. It tells the story of what Americans value—or at least, what we're spending our money on. Right now, we're spending it on Prime packages, life-saving medication, and keeping our lights on.
Stay focused on the cash flow, not just the hype.
