Market capitalisation – or ‘market cap’ – reflects the total value of a company’s outstanding shares, calculated by multiplying the share price by the number of shares. It’s a useful way to compare the size of listed companies across sectors and regions.

The rankings are based on reported market cap in USD, along with the latest available share price and each company’s primary listing country – as of 15 August 2025. A higher market capitalisation results in a higher rank.
