TL;DR
The Bureau of Economic Analysis estimated that U.S. real GDP grew at a 3.4% annual rate in the third quarter of 2026, above the 3% forecast cited by the Associated Press. Computers, other information-processing equipment and software contributed 1.09 percentage points, about 32% of growth, although imports of computer equipment complicate how much of that activity was produced in the United States.
The U.S. economy grew at a 3.4% annual rate in the third quarter of 2026, with computers and software contributing about 32% of the increase, according to the Bureau of Economic Analysis’ advance estimate published October 29. Consumer spending was the largest overall driver, while a sharp rise in business purchases of computer equipment put investment in technology near the center of the growth report.
The 3.4% figure is an annualized rate: it describes what the July-to-September pace would amount to over a year if it continued. The economy’s actual growth within the quarter was 0.8%. The estimate topped the 3% forecast in a FactSet survey cited by the Associated Press and followed a 2.2% annual rate in the second quarter.
BEA contribution figures show consumer spending added 2.52 percentage points to growth. Business fixed investment added 1.66 points, and inventories added 1.61. Imports subtracted 2.64 points, while exports subtracted 0.68. These components describe contributions to GDP growth, not separate growth rates for each category.
Business spending on computers and peripheral equipment rose at a 66.7% annual rate and contributed 0.72 percentage points. Adding other information-processing equipment and software brings the contribution to 1.09 points, or about 32% of the 3.4% total. Those categories together accounted for 65% of the increase in private fixed investment, based on the figures in the source material.

Where the 3.4% came from
Consumers carried most of the growth. Equipment, software and a big inventory build added the rest, and a surge in imports took a large slice back.
Contributions to growth, in percentage points
Each bar is one kind of spending. Bars right of the line added to growth, bars left of it subtracted. Together they make the 3.4%.

Advance estimate, the first of three; the second follows on 25 November 2026. “Annual rate” means the quarterly pace extended to a full year.

Technology Investment in the Growth Mix
The figures show why technology investment matters to the quarterly growth picture: equipment and software made a sizable contribution even as consumer spending remained the largest driver. The estimate does not mean that one-third of all U.S. economic activity was AI-related. The BEA does not publish a separate AI category, and the computer and software lines include purchases that may serve many purposes.
The reported investment also does not all translate into domestic production. Imports are subtracted from GDP because they were produced abroad. The report says imports rose at a 19.7% annual rate, with capital goods among the leading contributors. The source author estimates imported computer equipment reduced growth by about 1.1 percentage points, compared with a 0.72-point contribution from business computer purchases. That is the author’s calculation, not a distinct BEA estimate of AI’s net contribution.
For businesses and communities, the possible effects extend beyond technology firms. The source reports that private data-center construction was running at an $85 billion annual rate in August, 73% above a year earlier, while factory construction was down 20%. Data centers can support construction, utilities and equipment suppliers, but the figures alone do not establish how many lasting jobs or how much domestic value the projects will generate.

The Data Behind the AI Proxy
There is no official GDP line for artificial intelligence investment. The source uses computers and peripheral equipment as a narrow proxy because that category can include servers used in AI infrastructure. A broader measure adds other information-processing equipment and software. Neither measure identifies which purchases are specifically for AI, so the attribution should be treated as an estimate of technology spending, not a direct tally of AI’s contribution.
The source’s calculations from BEA tables put the combined contribution of information-processing equipment and software at an average of about 0.93 percentage points per quarter over the four quarters through September 2026, against average GDP growth of 2.1%. The source author calculates that as roughly 45% of growth over that period. The same analysis says business purchases of computer gear reached an annualized $504 billion in the third quarter, compared with $263 billion in the second quarter of 2025.
Other indicators provide a mixed picture of the investment boom. Census Bureau figures cited in the source show rapid growth in data-center construction, but a decline in factory construction. The Bureau of Labor Statistics reported that employers added 29,000 jobs in September, below the preceding year’s monthly average of 45,000. Those figures do not establish that technology investment caused the slower hiring.
“The BEA has no “AI” line. Economists use proxies.”

Imports and the Final GDP Estimate
The third-quarter figure is an advance estimate, the first of three BEA estimates. It relies partly on assumptions because some September data were not yet available, and later releases can revise the growth rate and its components. The second estimate is scheduled for November 25.
It is also unclear how much of the computer spending was specifically for AI, how much equipment was produced domestically, and how much of the investment will persist if companies reduce spending. The source’s estimate that imported computer gear offset about 1.1 percentage points is its own calculation; the supplied material does not present a BEA figure isolating AI-related imports or a definitive net AI contribution to GDP.
The source reports that the Nasdaq fell 2.9% on Friday after TechCrunch described “cracks” in the AI spending boom. That market move and characterization do not establish that technology investment has begun to fall or that the GDP contribution will reverse. The source provides no detailed evidence about which firms, projects or lenders would be most exposed to a slowdown.
The November Revision and Spending
The next scheduled data milestone is the BEA’s second GDP estimate on November 25, which will incorporate additional information and may change the headline rate or investment breakdown. Readers can then compare revised computer-equipment, software and import contributions with the advance figures.
Subsequent GDP releases and construction, employment and business-spending data will help show whether the surge in technology investment continues. For now, the official report establishes that computer and software categories made a large contribution to estimated third-quarter growth; it does not establish how much of that spending was AI-specific or how durable the pace will be.
Key Questions
How fast did the U.S. economy grow in the third quarter?
The BEA’s advance estimate was 3.4% at an annual rate for July through September 2026. The actual increase within the quarter was 0.8%.
How much did computers and software contribute?
Computers and peripheral equipment contributed 0.72 percentage points. Including other information-processing equipment and software raises the combined contribution to 1.09 points, about 32% of total growth.
Does the report show that AI produced one-third of growth?
No. The BEA has no separate AI line in GDP. Computers and software are proxies for technology investment, and the data do not identify which purchases were specifically for AI.
Why do imports matter to the computer-spending figures?
GDP measures production in the United States, so imports are subtracted even when U.S. businesses buy the goods. The source author estimates imported computer equipment offset some of the growth contribution, but that calculation is not a separate official BEA estimate of AI’s net effect.
When will the GDP estimate be updated?
The BEA’s second estimate is due November 25, 2026. It may revise the advance estimate as more data become available.
