America is producing more with each hour of work, but workers are receiving a smaller share of the result. The latest official data put that tension in unusually stark terms: nonfarm business productivity was 2.2% higher than a year earlier in the second quarter, while labor’s share of output fell to 52.8%—the lowest reading in a series that begins in 1947.
That combination is favorable for margins in the short run. It is less reassuring for an economy that still depends on household spending to turn technological progress into durable growth. For investors, the question is not simply whether artificial intelligence and automation are raising output. It is who captures the gains, how long that distribution can persist, and whether stronger profits eventually produce broader wage growth or weaker demand.
The big picture
Productivity is the cleanest route to higher living standards. When output per hour rises, companies can pay workers more, preserve margins and expand production without generating the same inflation pressure. It is also the economic promise behind the enormous flow of capital into data centers, software, advanced machinery and energy infrastructure.
The recent U.S. numbers offer evidence that the productive side of that story is real. The Bureau of Labor Statistics said nonfarm business productivity rose at a 1.4% annualized rate in the second quarter and 2.2% from a year earlier. Since the fourth quarter of 2019, productivity has grown at a 2.1% annualized pace—above the 1.5% rate in the previous business cycle and equal to the long-run rate since 1947.
The distribution of those gains is the complication. Real hourly compensation fell at a 3.3% annualized rate in the quarter and was down 0.1% from a year earlier. Unit labor costs rose only 1.4% over the year. Meanwhile, unit profits at nonfinancial corporations jumped at a 43.0% annualized rate in the quarter and were 17.8% higher than a year earlier.
One quarter does not establish a permanent regime. These measures are revised, cover different sectors and can be volatile. Even so, the direction is clear enough to matter: output per hour and profits are advancing faster than workers’ inflation-adjusted compensation.
What happened
The second quarter combined moderate aggregate growth with strong private demand and a sharp increase in profits. The Bureau of Economic Analysis estimated that real GDP grew at a 1.5% annual rate. Real final sales to private domestic purchasers—a measure of consumer spending plus private fixed investment—rose 4.2%. Profits from current production increased by $400.9 billion, after a $74.4 billion increase in the first quarter.
The productivity report shows how businesses converted that demand into income. Nonfarm output increased at a 1.7% annualized rate while hours worked rose only 0.3%. In manufacturing, output rose 5.4% and productivity increased 2.4%. Manufacturing unit labor costs declined 0.3% in the quarter, the first drop since the second quarter of 2021.
The labor market is not collapsing. Employers added 162,000 jobs in August, the unemployment rate held at 4.1%, and average hourly earnings rose 3.1% from a year earlier. But the composition was uneven. Food services and local government education accounted for much of the monthly gain, while the information sector lost 23,000 jobs. Over the prior 12 months, payroll growth averaged only 31,000 a month.
That is a different kind of expansion from one driven by broad hiring and accelerating real wages. Businesses are increasing output with limited growth in hours, keeping unit labor costs contained and protecting profits. The macroeconomy can look resilient even as the link between productivity and pay weakens.
Why it matters
A productivity boom becomes socially and economically durable when its benefits spread. Higher wages support consumption. Lower prices expand purchasing power. New investment creates complementary jobs. Competition transfers some of the surplus from producers to customers.
If the gains remain concentrated instead, the economy can develop a demand problem. Households that rely mainly on wages have a higher tendency to spend than wealthy asset owners. A smaller labor share can therefore weaken the broad consumer base even while equity holders benefit from higher margins. It can also intensify political pressure over automation, market concentration, taxes and trade.
Federal Reserve officials are openly debating this distribution question. Chair Kevin Warsh said at Jackson Hole that it is not yet clear whether the returns from AI will accrue first to owners of scarce assets—labs, chipmakers, energy producers and cloud providers—or eventually spread to businesses and consumers. Governor Michael Barr has outlined both possibilities: AI could democratize useful capabilities, or it could reinforce concentration and widen income and wealth gaps.
The monetary-policy effect is equally ambiguous. Productivity can lower inflation by reducing unit costs. But the investment required to build AI capacity can lift demand for capital, electricity and specialized labor before the supply benefits arrive. A profit-heavy productivity boom may therefore support equity earnings while keeping interest rates higher than investors accustomed to the pre-pandemic economy expect.
Chain reaction
The first link is capital spending. Companies buy computing equipment, software, machinery and power capacity because they expect higher future output.
The second is operating leverage. If production rises faster than labor hours, unit labor costs grow slowly or fall. The immediate benefit goes to margins, especially at firms that own scarce infrastructure or can deploy technology across a large revenue base.
The third is market structure. High fixed costs and scale advantages can concentrate returns among a small group of firms. Suppliers of chips, cloud capacity, power and proprietary models gain bargaining power, while smaller companies pay for access.
The fourth is household income. If wage growth and job creation do not keep pace with the value produced, consumers receive less of the expansion directly. Asset owners may gain through profits and stock prices, but ownership is uneven. The resulting spending pattern can become narrower and more sensitive to market wealth.
The final link is policy. Weak diffusion of gains raises pressure for training, competition policy, tax changes and worker protections. It can also change the Fed’s task: stronger potential output is disinflationary, but concentrated income and investment demand can produce a less predictable mix of growth, inflation and financial risk.
Market implications
Equities
The near-term earnings signal is constructive for companies with pricing power, scalable technology and modest labor intensity. Rising productivity with contained unit labor costs supports margins. The risk is concentration: valuations can assume that today’s leaders will retain most of the surplus even as competition, regulation and falling technology costs redistribute it.
Investors should separate firms that sell the infrastructure from those that can convert it into durable cash flow. Heavy capital spending is not proof of high future returns. The strongest position belongs to businesses with measurable output gains, repeatable demand and financing capacity—not merely large technology budgets.
Treasuries
Sustained productivity growth can raise the economy’s speed limit and ease inflation pressure. It can also lift the equilibrium interest rate if profitable investment keeps demand for capital high. Those forces point in different directions for bonds. The key evidence will be whether productivity gains show up in lower price growth and stronger real wages, or mainly in profits and investment demand.
Credit
Productivity divides borrowers. Firms able to automate successfully can defend cash flow and interest coverage. Labor-intensive businesses without pricing power may face a double squeeze from competitors with lower costs and financing markets that reward scale. Credit analysis should test whether announced technology spending has actually reduced unit costs.
The dollar and global markets
If the United States sustains faster productivity growth than its peers, capital can continue to favor U.S. assets and the dollar. But a more concentrated growth model also exports pressure: foreign markets may struggle to finance competing infrastructure, while global companies become more dependent on a small set of U.S. suppliers. The benefit to American markets is real, but so is the valuation and concentration risk.
Decision brief
- Track unit economics, not AI announcements. Look for output growth relative to hours, lower unit costs and cash returns on capital spending.
- Separate productivity from distribution. Rising output per hour is positive; a falling labor share shows that the gains are not yet reaching workers proportionately.
- Test consumer exposure. Companies dependent on broad discretionary spending are vulnerable if real compensation stays weak.
- Watch concentration. Scarce infrastructure supports pricing power today, but it also invites competition and policy scrutiny.
- Demand confirmation. The September 30 annual update to the national accounts and the November 5 productivity release can revise the picture.
Three horizons
Three months
Watch real wage growth, unit labor costs, corporate guidance and whether information-sector employment stabilizes. The September 30 BEA annual update will provide a major benchmark for GDP, income and profits. One strong profit quarter and one record-low labor-share reading are signals, not a settled trend.
One year
Look for diffusion. Productivity should spread beyond technology and durable manufacturing into services and smaller firms. The stronger version of the investment case includes rising real compensation, broader hiring and lower inflation—not profits alone.
Three years
The durable winners will be determined by who owns the scarce inputs and who turns them into lower prices, better products and higher worker output. If gains remain concentrated, expect more policy intervention and a less stable consumer base. If they broaden, productivity can support higher wages, healthy margins and faster noninflationary growth at the same time.
Bottom line
America’s productivity acceleration is an economic asset. The latest data also show that its rewards are arriving unevenly. Output per hour is rising, unit labor costs are contained and profits are strong, while labor’s share of output has fallen to a record low in the available series.
For investors, that split is both an opportunity and a warning. It supports near-term margins and the relative appeal of scalable U.S. businesses. Its durability depends on the next step: whether productivity gains reach paychecks and purchasing power before concentrated growth becomes a demand, political or valuation problem.
