What this site is

MarketCap Rankings puts the world's largest companies, exchange-traded funds, national economies, and macro assets on a single ranked list so you can compare their scale at a glance. Everything is expressed in U.S. dollars.

How each type is measured

• Companies (8 ranked) — market capitalization: share price multiplied by shares outstanding. The standard measure of a public company's size.
• ETFs (3 ranked) — assets under management (AUM): the total value of everything the fund holds. Funds don't have a market cap of their own, so AUM is the closest equivalent.
• Countries (4 ranked) — gross domestic product (GDP). A country has no market cap, so we use GDP as a widely understood size proxy. Note that GDP measures annual economic output, not asset value, so treat cross-type comparisons as order-of-magnitude context rather than apples-to-apples.
• Macro assets (3 ranked) — estimated total market value of all units in existence (for example, all above-ground gold at the current price, or bitcoin's circulating supply times its spot price).

Data freshness and accuracy

Figures were last reviewed July 2026. Market values move every trading day — sometimes dramatically — so the numbers here are rounded, approximate snapshots meant for comparing scale, not live quotes. Rankings near each other (say, #4 vs. #5) can and do swap places between updates.

What this site is not

Nothing here is investment advice, a recommendation, or an offer to buy or sell any security or asset. If you're making financial decisions, use live data from your broker or a professional data provider.
