Claude Code Product Leader Cat Wu Leaves Anthropic to Join OpenAI

Cat Wu, who played a major role in developing Anthropic’s Claude Code, has announced her departure from the company to join OpenAI. Wu confirmed the move on November 5, 2026, revealing that she would lead product management for OpenAI’s Core Products team. Her appointment represents a significant talent acquisition for OpenAI as competition between the two artificial intelligence companies continues to intensify.

Wu joined Anthropic in 2024 and helped transform Claude Code from a small internal experiment into one of the company’s most successful AI products. The coding assistant allows developers to delegate complex programming tasks, automate software development and manage large codebases. During her time at Anthropic, she also worked on other products, including Cowork. In her departure announcement, Wu described building Claude Code into an industry-defining product as one of the most important experiences of her career.

At OpenAI, Wu will report to Thibault Sottiaux and collaborate with enterprise product leader Nick Turley and consumer product leader Ashley Alexander. She said she respected OpenAI for bringing artificial intelligence to more than one billion people and emphasised her ambition to build AI agents that support individuals and businesses while keeping users in control. OpenAI confirmed the appointment, while Anthropic declined to comment on her departure.

The move comes at a critical time for both companies, particularly as OpenAI continues expanding its Codex coding platform to compete with Claude Code. Anthropic is also preparing for a major initial public offering, making the departure of a prominent product leader especially notable. Wu has not publicly explained why she left, but her move highlights how competition for experienced AI talent is becoming just as important as the race to develop more powerful artificial intelligence models.
