How this ranking is built

Ranks are recomputed from one source of truth: the latest delayed quote for each ticker multiplied by the share count on file, converted to US dollars. Preferred shares, warrants, units and rights are excluded before ranking, and multiple common share classes belonging to the same issuer are consolidated into a single entry. Foreign listings are converted at the prevailing FX rate, so a company can move several places on currency movement alone.

Frequently asked questions

Which company has the largest market cap in the world?

The lead rotates with every trading session. Through 2025 and 2026 NVIDIA, Apple and Microsoft have each traded above $3 trillion, with Saudi Aramco and Alphabet close behind.

How is a company's market cap calculated?

Share price multiplied by shares outstanding, summing all common share classes, converted to US dollars for non-US listings.

Why do market cap rankings differ between websites?

Different share counts (basic versus diluted, and whether all classes are included), different quote timestamps, and different FX rates applied to foreign listings.

Are private companies included?

Only companies with a listed, tradable share price can be ranked. Private funding-round valuations are negotiated prices for a slice of equity and are not market caps.
