Profit Margins of the Largest Companies

Nvidia leads Fortune Global 500's largest companies with a 55.6% profit margin, followed by Big Tech giants Microsoft, Alphabet, and Meta, all keeping over 30% of revenue as profit. In contrast, retailers, healthcare companies, and energy firms at the bottom of the ranking retain less than 5% of revenue as profit, reflecting differences in business models where software platforms have lower incremental costs than inventory-heavy or capital-intensive operations. Major tech companies are significantly increasing investments in AI infrastructure, which may reshape these profit margins as the industry becomes more capital-intensive.
