Note that "market value"/market cap is a quite restrictive view of a companies size - it's a measure of the value of issued shares, not how big a company is! Some things that might intuitively contribute to a companies bigness but won't be reflected in market cap: * Debt vs equity funding - a company that issues debt to raise money will have a smaller market cap than a company issuing an equivalent amount of equity. Enterprise value is a different measure which does include this (and would rank e.g. Toyota higher) * Taxation differences * Obviously publicly owned companies won't appear here at all, e.g. famously many oil & gas companies are government owned etc
