The work problem
According to a report Anthropic published on October 16, 2026, the company grew rapidly but hired less per dollar of revenue than an earlier generation of large tech companies. Engineering teams found that writing code and finding bugs could increasingly be offloaded to Claude, and an executive assistant and a financial manager built their own agents to take on time-consuming work such as scheduling, email triage and purchase request review. The company analyzed internal data on employment, AI use, output metrics, employee surveys, calendars and hiring decision records and interviewed 17 employees to measure how these changes reshaped work and employment.
Technology and data
Employees write code and fix bugs with Claude agents, while fleets of agents take on routine tests and checks, maintenance of infrastructure code and large-scale codebase translation. Personal assistant agents monitor calendars and messages to schedule meetings, compile to-do lists from incoming messages and brief employees on the people and purpose of upcoming meetings. Sales representatives handed email drafting and customer management software integrations to agents, lawyers handed off risk scanning and legal question triage, and recruiters handed off candidate sourcing and application tracking. Standing written instructions for agents grew from a few hundred in July 2025 to 8,500 a year later, and human work shifted toward writing specifications for agents, reviewing their output and monitoring agent pipelines.
Results
According to the report, in March 2026 the combined work hours of autonomous and interactive agents passed human work hours for the first time, and by August agents deployed by individual employees worked 6 times as many hours as the employees. Code commits per engineer reached 5 times their rate of six months earlier. Comparing 192 engineers who adopted coding agents with 74 who did not, the amount of code added rose sharply after adoption, and there was no difference in the rates at which code written by agents and code written directly by people was later removed or reverted. Lawyers processed more contracts, accounts payable processed more invoices and salespeople closed more deals.
Limits and open questions
The report notes that the company's rapid business growth over the same period may also have raised output and that employees did not adopt the tools at random, which could bias the estimates.
