TL;DR
US real GDP grew at a 3.4% annual rate in the third quarter of 2026, while business output has risen much faster than hours worked since late 2022. The figures show stronger productivity, but they do not establish that AI caused it: business adoption remains limited, and other explanations are possible.
US economic output is growing faster than the hours people work, but the latest figures do not establish that artificial intelligence is responsible. Real GDP grew at a 3.4% annual rate in the third quarter of 2026, while nonfarm business output rose 2.5% over the year to the second quarter as hours worked increased just 0.2%, according to the Bureau of Economic Analysis and Bureau of Labor Statistics.
The gap is also visible over a longer period. Calculations based on BLS indexes show that from the fourth quarter of 2022 through the second quarter of 2026, nonfarm business output rose 10.0% while hours worked rose 0.9%. Productivity—output per hour—grew about 2.5% a year over that span. The period begins around the public launch of ChatGPT, but timing alone cannot show that generative AI produced the increase.
The broader productivity trend has strengthened compared with the years before the pandemic. BLS data show productivity growing at an average annual rate of 2.1% since the end of 2019, compared with 1.5% a year from 2007 to 2019. In the year to the second quarter of 2026, productivity rose 2.2%, with output up 2.5% and hours up 0.2% in the nonfarm business sector.
Employment growth has been uneven by industry. Payrolls increased by 496,000 in the 12 months to September, according to the source’s account of BLS data. Health care and social assistance added 520,000 jobs, while information industries lost 120,000 and remained 12% below their November 2022 peak. The reported figures suggest that job growth was concentrated outside some technology-related industries; they do not identify AI as the cause of those losses.

Productivity Gains, Uneven Payoffs
The debate matters because productivity growth can support higher living standards over time, but its benefits depend on how the gains are shared. The source reports that the labor share of business output fell to 52.8% in the second quarter, its lowest level in the records dating to 1947, and that real private-sector wages declined 0.6% over the year to September. Those figures describe distributional pressures alongside growth; they do not by themselves show why wages or labor’s share changed.
Weak hiring can also affect people entering the workforce even when overall economic output is expanding. The source reports unemployment of 4.2% overall, compared with 8.0% for people aged 20 to 24 and 7.0% for Black workers. These rates indicate different labor-market conditions across groups, but the supplied material does not establish that AI caused the disparities. For workers and employers, the practical question is whether output gains lead to more opportunities and pay, or are achieved with fewer workers and a smaller share of income going to labor.
For policymakers, the distinction between a productivity trend and its cause matters. If AI is contributing, its effects may vary by occupation and industry, and could include changes to tasks rather than immediate job losses. If other forces account for much of the data, treating AI as the explanation could misdirect responses to slower hiring or wage pressure.

What the Economic Measures Show
Productivity is output divided by hours worked. It can rise when workers produce more in the same time, or when the same output is produced with fewer hours. The BLS figures cited here cover the nonfarm business sector: private businesses excluding farms. They do not cover every part of the economy, including government, nonprofits and households.
The discussion intensified after a Financial Times opinion column on October 31 asked whether the data were the first clear evidence of AI’s impact on the labor market. A Wall Street Journal headline the following day focused on strong growth that does not benefit everyone equally. Thorsten Meyer’s November 1 analysis says the full articles were behind paywalls and bases its discussion on official statistics from the BLS, BEA, Census Bureau, Federal Reserve and Eurostat. Its central caution is that correlation in the timing of AI and productivity growth does not establish causation.
There is evidence of investment associated with the AI build-out: the source says computers and software accounted for about a third of third-quarter growth, and that information industries contributed 0.52 percentage points to second-quarter growth of 2.2%. Those are sector and investment observations, not a measurement of how much AI itself added to productivity. The Census Bureau figure cited in the analysis says about one in four US businesses reported using AI in early October, without detailing how much that use changed output or staffing.
“Output grew 2.5% over the year to the second quarter while hours worked grew 0.2%, so productivity rose 2.2%.”
— Thorsten Meyer, citing the Bureau of Labor Statistics data
AI’s Role Is Not Measured
The main unresolved question is how much, if any, of the productivity increase is caused by AI. The figures show that output per hour rose during a period when generative AI tools became available and businesses invested in computers and software. They do not isolate AI’s contribution from other possible influences, such as conventional investment, changes in demand, staffing decisions or measurement effects.
Adoption figures also leave important gaps. The source says about one in four businesses reported using AI in early October, but does not specify the intensity of use, which tasks were affected, or whether adoption led to higher output, fewer hours or fewer jobs. It also says technology jobs began shrinking before generative AI was in wide business use. Layoffs were described as low while hiring slowed, but the supplied information does not establish how much of that pattern reflects AI.
The source additionally points to Europe as a contrast, describing more jobs alongside flat productivity, but provides no detailed figures here for a direct comparison. The timing and cause of US job changes, the durability of productivity gains and who ultimately receives the resulting income remain unsettled.
Watch Adoption and Labor Data
The next evidence will come from updated productivity, hours, employment and wage releases from federal statistical agencies, alongside Census Bureau measures of business AI use. Researchers and policymakers will need to compare changes across industries and time, while accounting for investment and other economic conditions, before assigning a share of productivity growth to AI.
For now, the data support a narrower conclusion: the US economy has recently produced more output with relatively little growth in hours, and productivity has outpaced its 2007–2019 pace. Whether AI is a major cause, whether the pattern will persist, and whether workers will share broadly in the gains are questions that subsequent releases may help answer.
Key Questions
Is AI responsible for US productivity growth?
The available figures do not establish that. Output and productivity rose during the period when generative AI became widely discussed, but the data cited do not separate AI’s effect from other causes.
How much did output and hours worked change?
From the fourth quarter of 2022 through the second quarter of 2026, calculations using BLS indexes show nonfarm business output up 10.0% and hours worked up 0.9%. These are changes over that period, not proof that AI caused the difference.
What does productivity mean in these figures?
Productivity means output per hour worked. It can increase when workers make more in the same amount of time or when businesses produce the same amount using fewer hours.
Are technology jobs falling because of AI?
The source reports that information industries lost 120,000 jobs in the 12 months to September and were 12% below their November 2022 peak. It also says tech employment began shrinking before generative AI was widely used, so the cause of the decline is not established.
What should readers watch next?
Follow upcoming productivity, employment, hours, wage and business AI-adoption data. More detailed evidence across industries will be needed to determine whether AI is changing output, staffing or both.
