What Wu said about leaving Anthropic
Wu’s farewell post said, “Friday was my last day at Anthropic,” referring to October 30, 2026. She thanked the Claude Code team and its users. Reporting on the post also says she thanked the teams behind Cowork and Tag. 13
15
Her farewell did not give a reason for leaving. Nor did it announce her next role: Wu shared the OpenAI news separately on November 5, saying she would lead product management for Core Products. 6

Wu’s role at Claude Code
Wu led product for Claude Code and was also associated with Cowork, according to reports on her departure and subsequent move. Coverage describes her as a prominent product leader for Claude Code, alongside creator Boris Cherny. 3

26
That establishes her reported role, but it does not by itself verify every account of the tool’s early development or quantify Wu’s individual contribution to Anthropic’s business. The company-wide financial figures reported around Anthropic’s IPO are not a standalone measure of Claude Code revenue. 37
How her exit fits the IPO timeline
Wu’s departure came amid Anthropic’s IPO preparations and followed October 24 departure announcements from Claude Code team members Thariq Shihipar and Anthony Morris. That timing is documented, but the available reporting does not show that the IPO caused Wu to leave. 5

Anthropic made its S-1 public on October 26 and planned to list on Nasdaq under the ticker ANT. An amended filing followed on November 2, according to contemporaneous IPO coverage. 37
39
A possible listing during the week of November 16 was reported as a target, not a confirmed date. Reports available at the time also said a price range and listing date had not been set. 43
46
The clearest account, then, is a two-step transition: Wu announced that she had left Anthropic, without giving a reason, and later disclosed that she was joining OpenAI. Her departure coincided with Anthropic’s IPO preparations, but the evidence does not establish a link between the two.
