US vs China GDP: the gap widened to a record $11.3 trillion in 2025

Key takeaways

US GDP reached $30.8 trillion in 2025, up 5.0 percent, its third straight year of roughly 5 percent nominal growth. China's dollar GDP reached $19.5 trillion, up 4.1 percent.
The gap between the two is $11.3 trillion, the widest in the 65-year World Bank series. China's economy peaked at 76.7 percent of US size in 2021 and has slipped to 63.4 percent since, so forecasts built on the 2021 trend have the crossover receding, not approaching.
Per person the economies are not close: $90,027 of output per American against $13,862 per Chinese resident, a 6.5-times difference. China's total size rests on population, not income.

What's happening

In current dollars, American output reached $30.8 trillion in 2025, growing 5.4 percent in 2024 and 5.0 percent in 2025. China's GDP reached $19.5 trillion, and its 4.1 percent dollar growth in 2025 was its fastest since 2021, after three years of nearly flat dollar output: 0.7 percent in 2022, a slight decline in 2023, 2.5 percent in 2024.

Because the US is growing from a larger base, similar growth rates still widen the distance. The gap has grown every year since 2021: $5.5 trillion that year, then $7.7, $9.5, $10.6, and now $11.3 trillion.

$11.3T

The US-China GDP gap in 2025: $30.8 trillion against $19.5 trillion, in current dollars. It is the widest in the World Bank series, which begins in 1960. In 2021 it was $5.5 trillion.

What the dollar comparison does and does not say

These figures are nominal and converted at market exchange rates, so the gap moves with the yuan as well as with growth. The reversal since 2021 reflects both: strong US nominal growth, and a Chinese economy whose dollar value stalled for three years. A comparison at purchasing-power parity would look different, but the dollar measure is the one that prices trade, debt, and markets.

The practical readings are two. Anyone extrapolating the 2010s, when China closed the gap from 11.9 percent of US size in 2000 to 76.7 percent in 2021, has four years of contrary data to absorb. And the per-person measures, $90,027 for the US against $13,862 for China, show how differently the same totals are produced: one economy from high output per person, the other from four times the people.

What the long chart shows

The chart's two curves compress a 65-year arc. China's line is barely distinguishable from zero until the 1990s: $1.2 trillion in 2000, 11.9 percent of US size. It crossed $10 trillion in 2014 and reached 41.1 percent of the US level by 2010 and 76.7 percent by 2021, the closest the two have ever been. The US line crossed $20 trillion in 2018 and has added more than $7 trillion since 2021 alone, a 29.7 percent rise over four years in which China's dollar economy grew 7.1 percent.

What to watch

The arithmetic of the gap: 5 percent growth on $30.8 trillion adds about $1.5 trillion a year, while 4 percent on $19.5 trillion adds about $0.8 trillion, so the gap keeps widening until China's dollar growth rate exceeds the US rate by roughly the ratio of the two economies. China's 2025 reacceleration is the first move in that direction in four years. The other variable is the exchange rate, which can move the dollar gap without any change in real output.

Common questions

What is the GDP of the United States in 2025?

$30.8 trillion in current dollars, per the World Bank measure. It grew 5.0 percent in 2025, following 5.4 percent in 2024.

How big is China's economy compared to the US?

China's GDP was $19.5 trillion in 2025, 63.4 percent of the US total. Per person the difference is larger: $13,862 of output per resident against $90,027 in the US.

Is China's economy still catching up to the US?

Not in dollar terms since 2021. China peaked at 76.7 percent of US GDP in 2021 and the ratio has fallen every year since, while the absolute gap widened from $5.5 trillion to $11.3 trillion, the largest in the series.

Why do these figures differ from GDP at purchasing-power parity?

These are nominal figures converted at market exchange rates, so they move with currencies as well as output. PPP comparisons adjust for local prices and put China closer to or above the US. The market-rate measure is used here because it is what prices trade, debt, and cross-border investment.
