Cat Wu, Anthropic's former head of product for Claude Code, joins OpenAI to lead product management for Core Products, according to her post and press reports
Cat Wu, Anthropic's head of product for Claude Code, says she is joining OpenAI to lead product management for Core Products. Start date not given.
On November 5, 2026, Cat (Catherine) Wu said on X that she is joining OpenAI. According to AI Weekly, which cites Business Insider, and OfficeChai, both relaying her post, she will lead product management for OpenAI's Core Products. This is neither investment nor legal advice.
The essentials
- The announcement: her post reads, as quoted by AI Weekly: "I'm joining OpenAI to lead product management for Core Products."
- The scope: Core Products covers ChatGPT, the API and Codex, according to AI Weekly. The two outlets describe her job differently.
- Her background: at Anthropic since August 2024, where she became head of product for Claude Code and later Cowork; she did not lead Claude Code as a whole.
- Not established: the exact title, the reporting line, the start date and the reasons for the move.
What does the announcement say?
She also says, as the outlets report, that she wants to work on reliable agents that keep users in control, and she expresses respect for OpenAI for showing that scaling works. Her last day at Anthropic was October 30, according to AI Weekly. OfficeChai says her start date at OpenAI was not disclosed. Neither source reports a reaction from Anthropic.
What exactly is the job?
AI Weekly says she will work alongside Thibault Sottiaux, whose Core Products scope covers ChatGPT, the API and Codex; it does not say she reports to him. OfficeChai calls her head of product management for the Core Products team and reports that she works alongside Nick Turley (enterprise products) and Ashley Alexander (consumer products) and, reportedly, reports to Thibault "Tibo" Sottiaux. The two descriptions do not match exactly, so the title and reporting line stay open.

What was her path at Anthropic?
Before Anthropic, OfficeChai says, she was a partner at Index Ventures. She joined Anthropic in August 2024 in the Research Product Management team, then became head of product for Claude Code and, later, Cowork (AI Weekly, OfficeChai). OfficeChai adds that she was a public voice for Claude Code alongside engineer Boris Cherny. She therefore led the product management of Claude Code, not Claude Code as a whole.

What do the outlets say about the context?
AI Weekly says hers is the third departure from the Claude Code team in about two weeks, after engineer Thariq Shihipar and Anthony Morris, developer of the desktop app; their next steps are unknown. The framing is the outlets' own: AI Weekly's editor's note calls her Anthropic's sharpest competitive threat and notes the move comes just before Anthropic's planned IPO; OfficeChai speculates about a wider exodus after the IPO and notes Anthropic's low voluntary attrition. These are comments, not facts.
What is not established?
The exact title, the reporting line and the start date; the reasons for the departure; whether more departures will follow; the effect on Claude Code or Codex; any link with Anthropic's IPO.
