AI’s productivity is finally hitting the real economy

A new report from the St. Louis Fed shows that economic output is trending higher, even though employee head-count has barely moved.

A few years ago, you might have blamed pent-up demand or a lucky sales run. In late 2025, the more honest explanation is that a growing share of your team has a chatbot open in the background.

The St. Louis Fed’s national U.S. adoption tracker, built on its Real-Time Population Survey, shows generative AI use jumping ten percentage points in a single year. Their new analysis of adoption and productivity argues those extra minutes are starting to show up in macro data.

Generative AI use is already a majority behavior for working-age Americans. The latest Real-Time Population Survey data show that by August 2025, 55 percent of adults aged 18 to 64 had used generative AI, up from 45 percent a year earlier. Work use rose from 33 percent to 37 percent and nonwork use from 36 to 49 percent.

Three years after launch, this adoption rate is far ahead of where personal computers and the early commercial internet were at comparable points in their rollout.

An earlier working paper on adoption using the same survey already found that nearly 40 percent of adults were using generative AI by late 2024, with between 1 and 5 percent of all work hours assisted by the technology. In other words, what looked like a wave of experimentation has hardened into routine use. For managers, that means your workforce is no longer waiting for a formal AI strategy. They are already automating pieces of their day, even if your policies and metrics have not caught up.

The picture is global, not just American. A 2024 global employee survey of more than 13,000 workers across 15 countries finds that about half of employees using generative AI save at least five hours a week. Nearly two-thirds of leaders say they are starting to redesign their organizations around it. Microsoft and LinkedIn’s 2024 Work Trend Index report similarly reports that 75 percent of knowledge workers worldwide are already using AI, with almost half starting within the previous six months and many doing so ahead of any official guidance.

Shadow use is now a structural feature of the workplace. A recent study of “bring your own AI” behavior based on payroll and survey........
