USA vs China vs India GDP 2026: Nominal, PPP, Growth and the Per-Capita Gap

There is no single winner — it depends on how you measure. By nominal GDP the order is the United States ($32.4T), China ($20.9T), then a distant India ($4.2T). By purchasing-power-parity GDP the order flips: China is #1 at ~$43.5T, ahead of the US ($32.4T) and India ($19.1T). By per-capita GDP the US is on a different tier entirely — ~$96,100 versus China's $30,900 and India's $13,200 PPP. India is the fastest-growing of the three by a wide margin (6.5% in 2026 vs China's 4.4% and the US's 2.3%), though INR depreciation has pulled its nominal ranking to 6th globally — behind Germany ($5.5T) and Japan ($4.4T). Aggregate size and individual living standard are not the same story.
