Apple sues OpenAI over trade secrets; IPO timeline at risk

Apple's lawsuit arrives at a critical juncture for OpenAI. The company has been preparing for a public offering, but major legal disputes—especially those alleging trade secret theft—typically require resolution or at least substantial progress before institutional investors and regulators approve an IPO. The specific focus on OpenAI's chief hardware officer suggests Apple's claims target the company's competitive efforts in hardware development, an area where Apple holds deep expertise and proprietary knowledge.

The scale of the alleged employee movement (more than 400 former Apple staff) is unusual and speaks to broader talent flows between Silicon Valley's giants. For OpenAI, the lawsuit carries dual risk: it questions the company's hiring practices and corporate governance to potential IPO investors, while simultaneously raising public questions about trust and data security in AI companies—a theme that has been gaining prominence across the industry this year.
