This list comprises the world's largest companies by consolidated revenue as of 2018, according to the Fortune Global 500 tally. American retail corporation Walmart has been the world's largest company since 2014.
The list is limited to 50 companies, all of which have annual revenues exceeding $110 billion US dollars. 21 companies are from North America, 17 from Asia and 12 from Europe. Only companies that publish financial data and report figures to a government agency are included. Therefore, this list is incomplete as it excludes large companies such as Cargill, Koch Industries, Kuwait Petroleum Corporation, and Saudi Aramco that don't publish financial data.
