Which country has the highest GDP?

The United States and China are the two countries in the world with the largest GDPs. Their position, however, varies depending on how GDP is calculated. The United States ranks top in nominal GDP, with a GDP of $20.93 trillion in 2020, compared to $14.7 trillion in China. Many economists, on the other hand, feel that using purchasing power parity (PPP) GDP as a measure of national wealth is more accurate. China is the world leader in this category, with a PPP GDP of $24.2 trillion in 2020, followed by the United States with $20.9 trillion.
