The snake is eating its own tail in Silicon Valley…

Over 90% of Anthropic’s internal codebase is now written by Claude, a striking metric for the AI sector.

A hot potato: It feels like we’re in the middle of a bragging-rights fight over which company has the most AI-written code. Google, Microsoft, Snap, and others have all talked about how much of their code is now AI-generated, but Anthropic appears to be leading the pack: its CFO said “90%-plus” of its code is written by Claude.

Speaking on an episode of Patrick O’Shaughnessy’s Invest Like the Best podcast, Anthropic CFO Krishna Rao mentioned the shockingly high figure.

Rao added that Claude is being used beyond coding tasks at the company. He talked about it being almost like an assistant or digital coworker.

Rao also mentioned Claude’s use in the finance department. He said the AI produces financial statements and can generate the company’s monthly financial review at a point where it is 90% to 95% complete.

It’s this sort of talk that brings up the inevitable question of what effect AI will have on jobs. Rao claims that because Claude is acting as a productivity “accelerant,” Anthropic has actually hired a lot more people.
