U.S. GDP Grows 3.4% Annualized in Q3 2026, Driven by Investment and Spending

U.S. economic growth accelerated in the third quarter, with real gross domestic product expanding at a 3.4% annualized rate after growing 2.2% in the second quarter, according to the U.S. Bureau of Economic Analysis’ advance estimate released Thursday.

“Real gross domestic product (GDP) increased at an annual rate of 3.4 percent in the third quarter of 2026 (July, August, and September), according to the advance estimate released today by the U.S. Bureau of Economic Analysis (BEA),” the agency said.

The pickup reflected stronger domestic demand during the summer. “The contributors to the increase in real GDP in the third quarter were increases in investment, consumer spending, and government spending that were partly offset by a decrease in exports. Imports, which are a subtraction in the calculation of GDP, increased,” the BEA said.

GDP is the broadest measure of U.S. economic output, and the third-quarter figure shows the economy grew faster in the summer than it did in the prior quarter. The composition of the report pointed to strength in spending and investment at home, even as trade acted as a drag because exports fell and imports rose. In the national income accounts, imports count as a subtraction from GDP.

Thursday’s figure is the advance estimate, the first of the BEA’s three regular readings on quarterly growth. The agency later issues second and third estimates as more complete data become available. Because the advance estimate is based in part on incomplete source data and assumptions for the final month of the quarter, it is subject to revision.

That matters because early GDP readings often change. Historically, the average absolute revision from the advance estimate to the third estimate has been about 0.5 to 0.6 percentage points, based on BEA revision data.

The third-quarter reading also extends a firmer growth pattern than earlier in the year. U.S. real GDP had been running at about a 2.5% pace in the first quarter of 2026 and 2.2% in the second quarter, making the 3.4% annualized gain in the July-through-September period a clear acceleration from the first half.

The result was broadly in line with economists’ expectations for stronger summer growth. Forecasters had generally looked for third-quarter GDP to come in above the second quarter’s pace, with many models and consensus estimates clustered in the low-3% range. The 3.4% reading fits that broader expectation rather than marking a major surprise.

The report arrived a day after the Federal Reserve held interest rates steady at its Oct. 27-28 meeting, though the GDP release itself centered on the economy’s faster growth pace and the balance between solid domestic demand and a trade-related drag.
