US economy grew at a 3.4% rate in Q3 2026, helped by AI spending

In short: The U.S. economy grew at a 3.4% annual rate in the third quarter of 2026, with steady consumer spending and more business investment tied to AI.

What happened

The U.S. economy grew at a 3.4% annualized rate in the third quarter of 2026. That was the fastest pace in a year and slightly above economists’ 3.2% forecast.

A big support came from consumers. Consumer spending rose at a 3.8% annualized pace, matching the previous quarter. This matters because consumer spending is a large part of the economy, it is like the main engine that keeps day to day business activity moving.

Businesses also spent more on AI-related projects. That included purchases of equipment, spending on “intellectual property” (things like software and research work), and construction of data centers (large buildings filled with computers that run online services). Higher oil prices linked to conflict in the Middle East were a headwind, but they did not stop overall growth.

There was one offset. Imports of AI-related capital goods, meaning advanced machines and hardware bought from other countries, weighed on GDP. In GDP math, imports are subtracted because they are counted as spending that happened outside the U.S.

The government described this number as an advance estimate, which means it can be revised as more data comes in. Analysts also said the expansion looks uneven, with strong stock-market gains and higher-income households doing much of the spending.

Why it matters

AI spending is showing up in the same place as roads, factories, and office buildings, as a real part of economic growth. The open question is whether this investment wave will keep going, and whether it will pay off enough to justify the costs.
