In PwC’s 2017 projection of GDP at purchasing power parity (PPP), China ranks first, India second, the United States third and Indonesia fourth among the 32 economies covered. That is an economic-output scenario—not a definitive forecast of which countries will hold the most overall power in 2050.
What does the 2050 ranking actually measure?
PwC’s 2017 report, The World in 2050, compares projected GDP at PPP. PPP adjusts for differences in local price levels, making it useful for comparing the volume of goods and services economies produce. It is not the same as GDP converted at market exchange rates, and the order of countries can differ under those measures.
PwC examined 32 of the world’s largest economies, which it said accounted for around 85% of world GDP. Its ranking is therefore broad, but it is neither a ranking of every country nor a measure of every dimension of national influence.
Which economies lead PwC’s 2050 projection?
| PwC’s 2050 GDP-at-PPP position | Economy |
|---|---|
| 1 | China |
| 2 | India |
| 3 | United States |
| 4 | Indonesia |
These are projections from PwC’s 2017 report, not observed 2050 results. PwC also projected that China would account for 20% of world GDP at PPP by 2050; that figure, too, is a model estimate rather than a guaranteed outcome.

Why did PwC expect emerging economies to gain ground?
PwC projected average annual growth of almost 3.5% for its E7 economies from 2016 to 2050, compared with 1.6% for its G7 economies. These are modelled growth rates over that period, not a record of what has already happened.
The groups are specific: PwC’s E7 comprises Brazil, China, India, Indonesia, Mexico, Russia and Turkey. Its G7 comprises Canada, France, Germany, Italy, Japan, the United Kingdom and the United States. PwC’s long-run shift depends in part on emerging economies improving institutions and infrastructure; the report presents this as a condition, not an assured result.

How should newer long-run scenarios change the outlook?
The OECD’s 2025 publication, OECD global long-run economic scenarios: 2025 update, offers a more recent framework for thinking about economic growth and uncertainty. It does not provide a directly comparable headline ranking of 2050 “superpowers” in the reviewed material.
The OECD cautions: “Long-run scenarios should not be treated as predictions of the future but rather as illustrations of some of the long-run challenges facing the global economy, how they might evolve, and how they might affect different countries.” Its framework considers influences on long-run output including labour efficiency, capital per worker, employment, age structure and climate-transition assumptions. These factors can change countries’ economic paths; they do not turn a scenario into a certain ranking.
Rank #3
Why GDP cannot settle who will be a superpower
A large economy can support national influence, but GDP alone does not measure military capacity, diplomatic reach, technological leadership, financial influence, alliances or cultural power. PwC’s ranking is about economic output, and the OECD scenarios are about long-run economic paths. Neither source combines those dimensions into a single forecast of overall power.
There is also a measurement distinction within long-run economic analysis. The OECD’s real GDP long-term indicator describes trend GDP in real terms, assessed using model-based analysis and expert judgement, in constant 2021 US dollars at PPP. It is a different measure and basis from PwC’s 2017 ranking; the figures should not be silently combined. The indicator is associated with the September 2025 OECD Economic Outlook 117 long-term scenarios dataset: OECD real GDP long-term forecast.

How to read claims about future superpowers
- Check the metric: GDP at PPP and GDP at market exchange rates answer different comparison questions.
- Check the date and horizon: PwC’s cited ranking dates to 2017 and projects to 2050; the OECD’s 2025 work is a newer scenario framework, not the same ranking.
- Look for assumptions: demographics, employment, labour efficiency, capital formation, institutions, infrastructure and climate-related assumptions can affect economic paths.
- Separate economic size from broader influence: a GDP table cannot by itself establish a country’s military, diplomatic, technological, financial or cultural standing.
