Apple and OpenAI were scheduled to appear in federal court in San Jose, California, on October 14, 2026. The hearing was set to consider Apple’s request for a preliminary injunction barring OpenAI from using any allegedly misappropriated trade secrets, as well as OpenAI’s motion to dismiss the lawsuit.

Apple alleges that OpenAI hired more than 400 former Apple employees to systematically obtain confidential information about product design, manufacturing processes and supply chain details. Apple claims OpenAI is using the information in its push into consumer hardware.

The legal dispute adds a challenge for OpenAI as it reportedly pursues a major valuation and a potential IPO.
