U.S. architecture is a $121.7 billion business. That’s how much firms generated in gross billings in 2025, according to “The Business of Architecture 2026,” a new report from the American Institute of Architects. New construction accounted for 54% of firm revenue, and the findings draw on data from nearly 900 firms.
Artificial intelligence has become part of the daily routine at most of them. AIA reports that 74% of firms use AI in day-to-day operations, with adoption reaching firms of all sizes. More firms are also developing formal AI strategies and workflows.
The report puts numbers on how firms are performing, too. Firms averaged $152,000 in net billings per employee in 2025. Billings and profitability grew, though financial performance varied significantly by firm size. The mix of work is changing as well, with shifts across institutional, commercial, residential and data center projects.
Beyond the balance sheet, the report documents gains in workforce diversity, with increases in both architecture staff and firm leaders who are women or members of racially and ethnically diverse groups. Firms are weaving resilience, climate adaptation and sustainability measures more deeply into project delivery. They are also paying closer attention to business continuity and succession planning, including ownership transition plans and written business plans.
