US labor productivity jumped 3.5% in Q3—the strongest gain in a year and the third straight quarter of improvement.

What's driving it? Companies are pouring money into AI, software, and equipment. Output per worker is rising faster than wages, which means unit labor costs actually fell 0.7% last quarter.

Translation: businesses are getting more done with less cost per unit produced. That's the productivity story everyone's been waiting for.

Nonfarm business output—stripping out government spending—grew at a 3.7% clip. Hourly comp rose 2.9%, but productivity outpaced it.

This isn't just a one-off data point. It's a trend. AI adoption is real, and it's showing up in the numbers. If this holds, it changes the conversation around margins, inflation, and even Fed policy.

Productivity growth like this can support corporate earnings without triggering wage-driven inflation. That's the sweet spot for equities.
