Anthropic CFO says AI now writes 90% of its code, changing white-collar jobs from execution to oversight

"“90 plus percent of our code is actually written by Claude Code,” he said, referring to Anthropic's AI coding product. The company's finance team is undergoing a similar transformation, Rao said. Anthropic now uses Claude to produce financial statements, while its monthly financial review process is “90 to 95% ready” before humans step in to review and interpret the results."

"“What used to take hours to produce,” Rao said of some internal reports, “now comes down to 30 minutes.” Rao argued that the productivity gains have allowed Anthropic employees to spend less time gathering information and more time making decisions about it. The shift is already happening inside Anthropic itself, Rao said."

"“We've hired a lot more people because of that,” Rao said, adding that he sees Claude as a productivity “accelerant.” “That actually means that we can get a lot more done, and that even as we grow the team, those people are more productive as they come up the curve on how to use Claude within our company.”"

"Rao described a workplace inside Anthropic where AI systems increasingly handle the execution layer of knowledge work—from software engineering to financial reporting—while humans shift toward oversight, judgment, and strategy. The comments offer a glimpse into how one of Silicon Valley's leading AI companies believes artificial intelligence will reshape white-collar jobs: not necessarily by eliminating workers outright, but by automating large portions of their day-to-day tasks and turning employees into supervisors of AI systems."

AI increasingly handles the execution layer of knowledge work, including software engineering and financial reporting. At Anthropic, Claude Code writes more than 90% of the company’s code. The finance team uses Claude to produce financial statements, with monthly financial reviews already 90 to 95% complete before human review and interpretation. Some internal reports that previously took hours are produced in about 30 minutes. Productivity gains reduce time spent gathering information and increase time spent making decisions. Humans focus more on oversight, judgment, and strategy while AI acts as a productivity accelerant that helps teams ramp up faster.
