What the Fortune 500 Is
The Fortune 500 is Fortune magazine’s annual ranking of the 500 largest U.S. companies by total revenue, published since 1955 (originally industrials only; expanded in 1995 to include service companies). Its companion, the Fortune Global 500, applies the same revenue rule to companies worldwide.
It is the definitive “biggest companies” list in American business culture — a ranking whose entire methodology fits in one sentence, by design.
What the Fortune 500 Ranks
The list ranks companies that do business in the United States and publicly report financial data — both listed corporations and private companies that file financial statements with a government agency.
Excluded: private companies that don’t report financials, and companies consolidated inside others.
Core Inputs Used by the Fortune 500
Exactly one ranking input:
- Total revenue — as reported for each company’s most recent fiscal year, including subsidiaries
Fortune publishes profit, market value, assets, and employee counts alongside — as data columns, not ranking factors.
How the Ranking Works (High-Level)
The method is pure ordering:
- Collect reported revenues for all eligible companies.
- Sort descending by total revenue.
- The top 500 publish as that year’s list; rank changes versus the prior year are noted.
Because fiscal years differ, the list compares companies across slightly different twelve-month windows — an accepted simplification.
Conceptual model: Line every company up by last year’s top line — biggest first, no questions asked.
Update Frequency
The Fortune 500 is published annually, typically in mid-year, from the most recently reported fiscal-year data.
Known Limitations and Criticisms
- Revenue ≠ success — the list ranks size, not health; a company can lose billions and climb the list
- Ignores market value — the stock market’s verdict (market cap) often tells a different story than revenue, especially for tech
- Accounting dependence — revenue recognition choices and M&A activity can shift rank without operational change
- Reporting gate — large private companies that don’t disclose financials are invisible to the list
Where the Fortune 500 Is Used
The list is used for:
- Corporate prestige and recruiting narratives (“a Fortune 500 company”)
- Economic analysis of U.S. business concentration
- B2B marketing segmentation and sales targeting
- Media framing of the American corporate landscape
Summary
The Fortune 500 is ranking reduced to its essence: one eligibility gate, one input, one sort. Its refusal to judge — size only — made it a durable neutral yardstick; the same refusal is why “biggest” and “best” remain permanently confused in the conversations it starts.
