Cat Wu, the product leader behind Anthropic's Claude Code, is joining OpenAI to lead product management for its core products team, she announced on X on Wednesday. OpenAI confirmed the hire; Anthropic declined to comment. Wu had left Anthropic the previous week, and the move hands OpenAI one of the people most responsible for turning a rival's coding tool from an internal prototype into a commercial success.
Claude Code became one of Anthropic's defining products under Wu, driving both revenue and the company's standing with software developers, and she was among its most visible public advocates. At OpenAI she will work on the company's competing coding tool, Codex, alongside Nick Turley on enterprise products and Ashley Alexander on consumer products, reporting to Tibo Sottiaux. OpenAI has been pushing Codex toward non-technical work and trying to regain ground after falling behind Anthropic in enterprise sales earlier this year; coding assistants have become central to both companies' growth.
The timing is pointed. Wu's departure lands just weeks before Anthropic's planned initial public offering, which the company has been pitching to investors as a growth story, and at a moment when it is working to shore up that narrative. Wu wrote that she had "no idea" whether leaving early would let her sell shares sooner than other employees and said it "wasn't a factor." Asked whether she would take a break, she replied, "post agi!"
This is not Wu's first exit from Anthropic. She and Claude Code creator Boris Cherny left for the AI coding startup Cursor in 2025 before quickly returning, according to The Information, and the pair then led Claude Code's rapid rise into 2026. Before Anthropic, which she joined in the summer of 2024, Wu was a partner at Index Ventures, a firm that later helped co-lead Anthropic's September 2025 funding round.
Individual hires rarely move an industry, but senior product talent is a scarce resource the leading labs increasingly poach from one another, and this one touches the products at the center of their rivalry. It also underscores how porous the line between OpenAI and Anthropic has become in a market where the same handful of people have built the flagship tools on both sides. Whether Wu can lift Codex the way she lifted Claude Code is the open question, and it will not be answered on the timescale of a headline.
