5 Largest Economies in the World by 2075

3. United States of America

Expected GDP in 2075 (in $ trillion): 51.5

While the U.S. may not be the biggest economy in the world by 2075, it will still have much higher GDP per capita than the two countries placing above it. By 2035, a century of dominance is expected to cede way and let countries currently categorized as emerging or developing countries become the biggest economies in the world.
