Global economic output is projected to grow 83% to $227 trillion by 2040, with the U.S. and China leading but narrowing their gap. India will rise to third place, while Asia's share of global GDP grows to 39%, reflecting a significant eastward shift in economic power.
Quick Facts
- Global economy projected to grow from $124 trillion to $227 trillion
- U.S. to remain largest economy at $52.9 trillion
- China to reach $47.9 trillion, narrowing gap with U.S.

The world economy is projected to grow 83% from approximately $124 trillion in 2026 to $227 trillion by 2040, according to projections from the Centre for Economics and Business Research (Cebr) in their World Economic League Table 2026. This expansion will substantially reshape global economic rankings, with the United States, China, and India collectively accounting for 51% of worldwide output by 2040.
The United States is projected to maintain its position as the world's largest economy, reaching $52.9 trillion in nominal GDP by 2040, while China will narrow the gap to approximately $5 trillion—down from $10.7 trillion in 2026. China's economy is expected to reach $47.9 trillion, with its share of global GDP rising from 17% in 2026 to 21% by 2040, while the U.S. share falls from 26% to 23%. According to IMF data, China already ranks as the world's largest economy by purchasing power parity in 2026.
India will rise to third place globally, climbing from fourth position in 2026. The Indian economy is projected to more than triple, growing from $4.5 trillion to $14.1 trillion, surpassing both Germany and Japan. Indonesia will also see significant gains, entering the top 10 and climbing from 17th place to 8th, overtaking Italy. Germany will drop from third to fourth place, while Japan falls from fifth to sixth.
Asia's share of global output is expected to expand from 32% in 2026 to 39% by 2040, reflecting broader economic reorientation in the region. Europe's share will decline from 26% to 21%, while North America's falls from 30% to 27%. These projections reflect nominal GDP in current U.S. dollars and are not adjusted for inflation, based on estimated output across approximately 190 economies.
Why This Matters
These projections affect capital allocation, trade relationships, and geopolitical influence over the next 15 years. Investors, multinational corporations, and policy makers use such forecasts to assess market opportunities and supply chain resilience. The narrowing GDP gap between the U.S. and China, combined with Asia's rising share of global output, signals structural shifts in where economic activity concentrates and where currency valuations and investment returns may shift. India's projected rise to third place reflects growing working-age population and labor cost advantages, which will influence outsourcing decisions and consumption markets.
