The Adoption Curve
10.0% — up from 6.6% a year ago, nearly 3x the rate two years ago
What is the current The Adoption Curve?
17.3% of U.S. businesses reported using artificial intelligence in any business function, according to the Census Bureau's Business Trends and Outlook Survey (BTOS). AI adoption is accelerating across sectors, with the rate of adoption serving as a leading indicator of potential workforce displacement. Source: Census Bureau BTOS.
One in ten U.S. employer businesses now uses AI in production — nearly triple the share from two years ago, and the adoption curve is steepening, not flattening.
The Census Bureau's Business Trends and Outlook Survey reached 10.0% in its most recent reading for the share of U.S. employer businesses using AI in their operations. Two years earlier, in September 2023, that share was 3.7%. The line has bent upward in each successive reading, not flattened.
Ten percent sounds modest until you work through what it represents. The Census BTOS universe is employer firms — roughly 5.8 million businesses that together employ most of the private-sector workforce. A shift from 3.7% to 10.0% in 24 months is millions of workers whose employer has added AI to production workflows in the last two years.
Adoption is a leading indicator, not an outcome. The workforce consequences show up downstream in series like The AI Cut, where Challenger began tracking AI-attributed layoff announcements as a distinct category that didn't exist three years ago, and The Tech Drought, where information-sector job openings have fallen sharply from their 2025 highs. The Horizon tracks the capability side — how long a task AI can complete on its own — and that curve is steeper still.
The adoption curve is the upstream force. When it bends, the hiring data bends a few quarters later. American Default's American Worker Index treats this as the leading edge of AI-related household distress, not because adoption causes distress directly, but because the mechanism from adoption to displacement to lost income runs through it.

Frequently Asked Questions
What percentage of U.S. businesses use AI?
17.3% of U.S. businesses reported using AI in any business function, according to the Census Bureau's Business Trends and Outlook Survey. The rate varies significantly by industry, with technology and financial services showing the highest adoption.
Why does AI adoption matter for household financial distress?
Rising AI adoption is a leading indicator of potential workforce displacement. As businesses automate tasks previously performed by humans, workers in affected roles face layoffs, longer job searches, and potentially permanent earnings losses — all of which feed into household financial distress.
Where does AI adoption data come from?
The Census Bureau's Business Trends and Outlook Survey (BTOS) is a biweekly survey of U.S. businesses covering current and anticipated use of AI technologies. It is one of the few government-sourced measures of AI adoption across the economy.
