The world’s fastest-growing economies are expected to play a major role in shaping global economic expansion over the next five years. New forecasts indicate that while many countries will grow, a few large economies will produce most of the additional output (GDP) through 2030.
Projections from the International Monetary Fund’s (IMF) World Economic Outlook show that China, the United States, and India will account for nearly half of the increase in global GDP between 2026 and 2030.
Together, the three countries are expected to generate about 49.7% of the total economic output added worldwide during that period.
Major economies expected to drive global output
China is projected to lead in total economic expansion. The country is expected to add about $5.7 trillion to global GDP over the five-year period. The United States follows with an estimated increase of about $5.0 trillion.
Although growth rates in these large economies may appear modest compared with smaller developing nations, their economic size means even moderate expansion produces large gains in dollar terms.
India ranks third in projected GDP additions. Its economy is expected to grow by about $2.1 trillion by 2030. India also stands out among the world’s fastest-growing economies. It appears both among the countries adding the most output and among those recording strong percentage growth.
China (+$5.7T), the U.S. (+$5.0T), and India (+$2.1T) account for nearly half (49.7%) of total expected GDP added through 2030.

Several other major economies are also forecast to contribute significantly to global expansion. The United Kingdom is projected to add about $974.1 billion to GDP by 2030. Germany could add roughly $685.6 billion, while Japan is expected to contribute about $656.3 billion.
Large emerging markets are also expected to increase their economic output. Indonesia may add about $528.9 billion to global GDP, followed by Brazil with about $521.8 billion. Canada is forecast to add roughly $489.6 billion, and France about $450.6 billion. Mexico, Australia, Turkey, and Spain are also projected to record notable gains.
Overall, the top 10 economies contributing to GDP expansion are expected to account for about 66.5% of the total global growth by 2030.
World’s fastest-growing economies and emerging growth markets
While the largest economies dominate in total output gains, the fastest percentage growth is expected in smaller markets. According to IMF projections, Suriname is forecast to record the strongest growth. Its economy is expected to expand by about 137% between 2026 and 2030.
Other rapidly expanding economies include Malawi, with projected growth of about 75.4%, and Ethiopia, with roughly 73.3%.
Guinea, Uzbekistan, Yemen, Zambia, Egypt, and Uganda are also expected to see strong economic growth during the same period. India also appears in this ranking with a projected growth of about 47.1%.
