$1 trillion valuation

A **$1 trillion valuation** refers to the estimated total market value of a company being equal to one trillion U.S. dollars. In public markets, this is typically measured by a company’s **market capitalization**—that is, the share price multiplied by the total number of outstanding shares. When a privately held company reaches such a valuation, it is based on investor assessments from fundraising rounds rather than stock market prices.
