Apple had the world’s largest market capitalization at the end of 2021.
At the close of 2021, Apple’s equity value was approximately $2.9 trillion, placing it ahead of Microsoft and Saudi Aramco in widely reported global rankings. The exact figure changed with daily share prices, but Apple remained the leading listed company at that year-end date.
Apple’s position reflected the scale of its hardware ecosystem and the recurring income generated by services. The company’s stock had also benefited from investor confidence in its brand, customer base, supply chain, and ability to introduce new products.
Year-end rankings are snapshots, not permanent titles. Companies can exchange positions within hours when their share prices move. Rankings may also differ slightly if data providers use different share counts, currencies, or closing times.
