-
Productivity jumped 4% as output grew 4% while hours worked barely moved, the kind of labor-light growth the AI spending boom promised, Meta Platforms (META) included.
-
Workers are getting a thinner slice: labor's share of output hit 53%, the lowest since 1947, while corporate profits climbed 21% from a year earlier.
-
Crediting AI is premature, since mining and manufacturing outpaced the information sector in output growth and the data don't isolate AI's contribution.

American businesses squeezed more output from each hour of work this summer than they have in a year. Nonfarm business labor productivity rose at a 3.6% annualized rate in the third quarter of 2026. That followed 2.1% in the second quarter and 1.4% in the first, making it the third consecutive quarterly improvement.
The detail behind the headline matters more than the headline. Nonfarm output grew 3.7% annualized while hours worked rose just 0.1%. Companies delivered a full quarter of growth without adding significant labor, exactly what the AI spending boom promised. The productivity revival looks real. The more important question for households is who keeps the gains, and so far the answer is shareholders.
Where the Extra Output Is Going
Hourly compensation rose 2.9%, but productivity grew faster, so unit labor costs slipped. The Bureau of Labor Statistics (BLS) index fell to 124.39 from 124.6 in the second quarter, the first quarterly decrease since Q2 2025. For a company, that is a margin gift: the same payroll covers more product.
Profits already show it. Corporate profits reached a $4.71 trillion annual rate in the second quarter, up 20.8% from a year earlier, according to the Bureau of Economic Analysis. Manufacturing profits jumped to $1.05 trillion from $812 billion one quarter earlier.

Many successful investors eventually reach the same moment. The saving is done, the portfolio is built, and the question quietly changes from how much can I grow this to how much can I take out? Get that second question wrong and decades of good investing can come apart in a handful of years.
That is exactly what The Definitive Guide to Retirement Income helps answer. It covers what your retirement could actually cost, which income sources are worth using, and the withdrawal math that decides whether the money lasts. It is free today from Fisher Investments. Read More Here ›
Workers are getting a thinner piece. Labor's share of nonfarm business output fell to 53.0%, the lowest in a BLS series dating to 1947. Real hourly compensation rose 1.1% in the quarter. Yet inflation-adjusted average hourly earnings for private workers stood at $11.26 in September, below $11.32 a year earlier.
Why Crediting AI Is Premature
The BLS data don't isolate AI's contribution. Output growth is also coming from heavy industry. In the second quarter, mining value added grew 13.7% and manufacturing 5.5%, outpacing the information sector's 2.7%. Factory and energy output explain part of the gain, alongside software and automation.
The pressure to keep it going is building anyway. A top executive at Meta Platforms( NASDAQ:META ) told the Financial Times this week that "population collapse" makes AI productivity gains vital. With labor supply growing slowly, output per hour is the only lasting way to expand the economy, and that explains the timing as companies facing tight labor markets use technology in place of new hires.
Inflation Relief Has Limits
In theory, faster productivity lets employers absorb raises without lifting prices. Average hourly earnings reached a preliminary $38.00 in October, up from $36.85 a year earlier. Unit labor costs still rose 2.4% year over year. The core Personal Consumption Expenditures (PCE) price index, the Fed's preferred measure, rose 0.3% in September to a new high. Real GDP grew at a 3.4% annualized pace in the third quarter. One strong productivity quarter will not convince the Fed that disinflation is certain.
What to Watch in the Next Two Reports
Start with the BLS revision of third-quarter productivity. If the gain holds above 3% and the fourth quarter adds a fourth straight improvement, the AI-dividend argument gets much stronger.
The more telling number is hours worked. If output keeps climbing while hours stay flat and labor's share sets another record low, the productivity boom becomes a profit story. Slow hiring is the cost. If hours start rising alongside output, workers will finally begin to share in the gains.
