TL;DR
U.S. business-sector output rose 10.0% from the fourth quarter of 2022 to the second quarter of 2026, while hours worked increased 0.9%, according to calculations based on Bureau of Labor Statistics indexes. The figures point to faster productivity growth, but they do not show that AI caused it; employment gains, pay and outcomes for younger workers remain uneven.
U.S. business output has risen far faster than hours worked since late 2022, a productivity pattern now prompting debate about whether artificial intelligence is changing the labor market. The figures show a widening gap between output and labor input, but do not establish that AI caused it; hiring, wages and job growth remain uneven.
The Bureau of Economic Analysis said real U.S. gross domestic product grew at a 3.4% annual rate in the third quarter of 2026, up from 2.2% in the second quarter. Consumer spending, investment and government spending contributed to the increase. The GDP figure describes overall economic output; it is not the same measure as the Bureau of Labor Statistics’ productivity data, which cover the nonfarm business sector.
In that sector, BLS data show output grew 2.5% over the year to the second quarter of 2026, while hours worked rose 0.2%; measured productivity increased 2.2%. The source’s calculations from BLS indexes show output up 10.0% from the fourth quarter of 2022 to the second quarter of 2026, against a 0.9% rise in hours worked. That comparison is over the stated period and is not proof of what caused the difference.
Labor-market measures offer a more mixed picture. Payrolls increased by 496,000 over the 12 months to September, with health care and social assistance adding 520,000 jobs. Information industries lost 120,000 jobs over that period and remained 12% below their November 2022 peak. The source reports an overall unemployment rate of 4.2%, compared with 8.0% for people aged 20 to 24 and 7.0% for Black workers.

Productivity Gains, Uneven Labor Outcomes
The figures matter because productivity growth can support higher output without a matching increase in hours, but the benefits do not necessarily reach workers evenly. The source reports that the labor share of business output fell to 52.8% in the second quarter, its lowest level since the records began in 1947, and that real private-sector wages fell 0.6% over the year to September. Those measures point to pressure on workers’ share of the gains, though they do not by themselves explain why the changes occurred.
The employment pattern also differs by industry and age. Health care and social assistance accounted for more job growth than the total net increase across payrolls, while information-sector employment declined. The source says hiring has been slow even as layoffs remain low. For younger workers, an unemployment rate of 8.0% among 20- to 24-year-olds suggests a tougher labor market than the overall rate indicates. These figures are relevant to workers and employers assessing whether rapid output growth is translating into broad-based job opportunities and pay gains.
For businesses, the central issue is not simply whether productivity has improved, but what is driving it and how durable the change will be. If technology contributes, firms may be able to produce more with existing staff. But investment, changes in demand, workforce composition and other factors can also affect output per hour. The current data establish the productivity pattern, not its cause or the distribution of its gains.

How the Post-2022 Comparison Works
The analysis uses the fourth quarter of 2022 as a reference point, shortly after ChatGPT launched on November 30 of that year. That makes the period useful for examining what happened alongside the spread of generative AI, but the date is not a controlled test of AI’s effect. Productivity is calculated as output divided by hours worked; it can rise when output increases faster than hours, or when hours fall relative to output.
BLS’s nonfarm business-sector measure covers private businesses other than farms. It excludes government, nonprofits and households, so it does not describe every part of the economy. The source reports that productivity grew 2.1% a year from the end of 2019, compared with 1.5% a year from 2007 to 2019. This longer comparison suggests that productivity growth has been stronger than in the previous period, but it does not identify a single cause.
The source also reports that only about one in four U.S. businesses said it used AI in an early-October Census Bureau survey. That measure makes clear that AI adoption was not universal at the time, though it does not capture every kind or intensity of use. The source notes that technology-sector jobs began declining before generative AI was widely used in business. Together, those points counsel against treating the timing of productivity gains as evidence that AI alone produced them.
“Numbers can show that two things happen at the same time. They rarely show that one causes the other.”

AI’s Contribution Is Not Measured
The available figures do not isolate how much of the productivity increase came from AI, or whether AI caused any of it. The source says computers and software drove about a third of third-quarter GDP growth, with much of that attributed to AI-related investment, but this is not the same as measuring AI’s effect on output per hour across businesses. The precise composition and causal contribution are not established by the headline productivity statistics.
Other explanations may fit the same pattern, including investment in non-AI technology, shifts in industries or workers, and changes in business demand. The source notes that the information sector’s job losses began before generative AI was widely used. It also reports AI use by about one in four businesses, but that survey figure does not say how extensively firms use AI or whether adoption improved their productivity.
It is also unclear whether the stronger productivity growth will persist, how gains are distributed across occupations, or whether weaker hiring reflects changes in labor demand, worker supply or other conditions. The source’s comparison with Europe—more jobs alongside flat productivity—is a contrast, not evidence that one region’s pattern explains the other’s.
More Data Needed on Adoption and Jobs
The next evidence will come from updated BLS productivity and employment releases, further GDP estimates from BEA and new Census Bureau measures of business AI use. Those series can show whether the gap between output and hours continues and whether adoption spreads across industries, but they will not automatically identify causation.
Researchers and policymakers will need evidence linking firms’ technology adoption to changes in output, hours, hiring and pay over time. For workers, subsequent employment and wage data will help establish whether the current weakness in some groups persists. For now, the confirmed development is faster productivity growth alongside modest hiring and uneven outcomes—not a definitive finding that AI is replacing workers or producing the gains.
Key Questions
What is the main development?
U.S. business output has grown much faster than hours worked since late 2022, while recent GDP and productivity figures show continued economic growth. The pattern has renewed debate about AI’s role, but does not identify a cause.
Do the figures prove that AI is raising productivity?
No. The figures measure output and hours, not AI’s separate effect. They show a correlation in timing, not proof of causation, and other economic changes could contribute.
Which workers or industries show weaker employment?
The source reports that information industries lost 120,000 jobs over the 12 months to September and remained 12% below their November 2022 peak. It also reports 8.0% unemployment for people aged 20 to 24, compared with 4.2% overall.
Are workers receiving a larger share of output?
Not according to the figures cited in the source. The labor share of business output was 52.8% in the second quarter of 2026, while real private-sector wages fell 0.6% over the year to September. These measures describe outcomes but do not explain their causes.
What evidence could clarify AI’s role?
Updated productivity, employment and wage data, alongside more detailed measures of business AI adoption and firm performance, could clarify whether AI use is associated with changes in output and labor demand. The current data do not settle that question.
