The Fortune 500 is an annual list, published by Fortune magazine, of the 500 largest companies in the United States ranked by total revenue for their fiscal year.
That's the whole definition. Revenue — not profit, not market cap, not employee count. The company that sells the most sits at number one.
Simple concept. But if you sell B2B, "Fortune 500" is more than trivia. It's shorthand for the biggest, most complex, most lucrative accounts you can chase. This guide covers what the list actually is, how it's built, how it differs from the Global 500 and Fortune 100, and what it really means to sell into these companies.
What Is the Fortune 500?
The Fortune 500 ranks the 500 highest-revenue companies in America. Fortune magazine has published it every year since 1955, when General Motors topped the first edition.
Key facts about how the list works:
- Ranked by revenue. The metric is total revenue for the company's fiscal year. A company can lose money and still rank high — profitability doesn't affect position.
- US companies only. The list covers companies incorporated and operating in the United States that file financial statements with a government agency.
- Public and private. It's not just publicly traded companies. Private companies qualify too, as long as their revenues are available through required filings.
- Refreshed annually. Fortune publishes a new edition each year, typically in early summer, based on the most recent fiscal year results. Companies rise, fall, merge, and drop off constantly.
- Walmart dominates. Walmart has held the number one spot for most of the last three decades on the strength of its enormous retail revenue.
Making the list requires billions in annual revenue — the cutoff moves each year with the economy, but every company on it is a giant by any normal standard.
One more thing worth knowing: "Fortune 500" is a trademark of Fortune Media. That's why you'll see careful phrasing like "Fortune 500 company" in marketing — companies love the label because it signals scale instantly.
How Is the Fortune 500 List Built?
Fortune's methodology is refreshingly mechanical. No panels, no votes, no vibes.
- Gather revenue data. Fortune collects total revenues for the fiscal year from company filings — 10-Ks for public companies, other government filings for private ones.
- Apply eligibility rules. The company must be incorporated in the US, operate in the US, and file financial statements with a government agency. Subsidiaries of foreign companies don't qualify on their own.
- Rank by revenue. Sort descending. Position 1 through 500. Done.
Because it's purely revenue-ranked, the list skews toward industries that move huge dollar volumes: retail, energy, healthcare, tech, and finance fill the top ranks. A wildly profitable software company can rank below a thin-margin grocery chain that moves more total dollars.
That's also why the list is a moving target. Mergers combine two entries into one. Acquisitions by foreign parents remove companies. A commodity price swing can shuffle energy companies dozens of places in one year.
Fortune 500 vs Global 500 vs Fortune 100: What's the Difference?
People mix these up constantly. The differences are simple:
| List | Scope | Size | Ranked by |
|---|---|---|---|
| Fortune 500 | US companies | 500 | Annual revenue |
| Fortune Global 500 | Companies worldwide | 500 | Annual revenue |
| Fortune 100 | US companies | Top 100 | Annual revenue |
| Fortune 1000 | US companies | 1,000 | Annual revenue |
- Fortune Global 500 applies the same revenue ranking to the whole world. Chinese, European, and Japanese giants appear alongside American ones, so plenty of Fortune 500 companies don't crack the Global 500's upper ranks.
- Fortune 100 is simply the top 100 entries of the Fortune 500 — the elite of the elite. When a vendor says "we serve Fortune 100 companies," they're claiming the very largest accounts in America.
- Fortune 1000 extends the same ranking to 1,000 companies. The back half (501-1000) gets less press but includes thousands-of-employees enterprises that many B2B sellers find more reachable than the top tier.
Related terms you'll hear: the S&P 500 is a stock market index chosen by committee with different criteria entirely — being in one says nothing about being in the other. And "enterprise" in sales usually means any company big enough to have complex buying processes, which extends far beyond any Fortune list.
Why Do Salespeople Care About the Fortune 500?
Because the label is a proxy for three things every B2B seller wants to know about an account: budget, complexity, and reference value.
Budget. Fortune 500 companies spend enormous sums on software, services, and suppliers. A single enterprise contract can be worth more than a hundred SMB deals. That's why account-based selling teams build target lists straight from the Fortune 500 and Fortune 1000.
Complexity. The money comes with process. Buying committees with many stakeholders. Procurement reviews, security questionnaires, legal redlines. Sales cycles measured in quarters, not weeks. Selling into a Fortune 500 account is a campaign, not a conversation.
Reference value. Landing one household name changes how every future prospect sees you. "Trusted by a Fortune 500 retailer" answers the risk question before it's asked. Many startups deliberately take a modest first enterprise deal because the logo is worth more than the revenue.
There's a fourth, quieter reason: the list is public. Anyone can see exactly which companies qualify, which industries they're in, and how they're trending. As targeting data goes, it's free and clean.
What does outreach to Fortune 500 companies look like?
Different from SMB outreach in almost every way:
- You sell to a committee. Multiple contacts per account — the user, the budget owner, the technical evaluator. One champion isn't enough.
- Multi-threading is survival. People change roles constantly at big companies. If your only contact leaves, the deal dies with them unless you've built more relationships.
- Follow-up runs for months. Enterprise deals go quiet for weeks at a time between procurement steps. The seller who follows up patiently and consistently is often the one who wins.
- Relevance beats volume. A VP at a Fortune 500 company gets flooded with vendor emails. Deep account research and a message about their specific initiatives is the only way through.

How ClickReach Fits Enterprise Outreach
Long sales cycles are where follow-up discipline breaks down. A rep juggling twenty enterprise accounts across six-month cycles cannot reliably remember who needs a nudge this week — and forgotten follow-ups are how enterprise deals silently die.
ClickReach is built for exactly that persistence problem: multi-step sequences that keep gentle follow-ups going automatically, a CRM workspace that tracks every contact and conversation per account, and sender rotation to keep deliverability healthy while you multi-thread. Flat $25/month, 15-day free trial.
Honest note: no tool shortcuts enterprise sales. The research, the relationships, the patience — that's on you. ClickReach just makes sure that six weeks into a quiet procurement phase, your follow-up still goes out on time.
Frequently Asked Questions
What is the Fortune 500 in simple terms?
The Fortune 500 is a yearly list of the 500 biggest companies in the United States, ranked by how much revenue each earned in its fiscal year. Fortune magazine has published it since 1955. Bigger revenue means a higher rank — profit, stock price, and company size in employees don't affect the ranking at all.
How does a company get on the Fortune 500?
A company must be incorporated and operating in the US, file financial statements with a government agency, and earn enough annual revenue to rank among the top 500. There's no application. Fortune compiles revenue figures from filings each year and ranks them. Both public and private companies qualify if their financials are available.
What is the difference between the Fortune 500 and the Global 500?
The Fortune 500 covers only US companies, while the Fortune Global 500 ranks the 500 largest companies in the world by revenue. Both are published by Fortune and both rank purely on revenue. Many American Fortune 500 companies appear on the Global 500 too, alongside giants from China, Japan, and Europe.
Is the Fortune 500 the same as the S&P 500?
No. The Fortune 500 is a magazine's revenue ranking that includes private companies. The S&P 500 is a stock market index of publicly traded companies selected by a committee using criteria like market capitalization and liquidity. A company can be in either list without being in the other.
Why do B2B sellers target Fortune 500 companies?
Three reasons: budget, scale, and proof. These companies spend heavily with suppliers, a single contract can outweigh dozens of small deals, and winning one gives you a reference logo that reassures every future buyer. The trade-off is longer sales cycles, buying committees, and procurement processes that demand patient, well-organized follow-up.
