Apple Files Lawsuit Against OpenAI, Alleging Widespread Trade Secret Theft Amidst Escalating Hardware Rivalry

Apple has initiated a comprehensive legal challenge against OpenAI, filing a 41-page lawsuit on Friday, July 11, 2026, that alleges widespread trade secret theft. This action marks a significant escalation in tensions between the two tech giants, who just two years prior, announced a strategic partnership at WWDC 2024 to integrate ChatGPT into the iPhone, branded as “Apple Intelligence.” The lawsuit comes as OpenAI intensifies its foray into hardware, a move Apple reportedly views as a direct threat to its core business. OpenAI’s hardware ambitions include the acquisition of Jony Ive’s stealth startup, IO, for an reported $6.5 billion, with Ive now collaborating with Sam Altman on a device rumored to be a screen-free home smart speaker designed to challenge the iPhone’s dominance.

The lawsuit details several bombshell allegations, asserting that OpenAI’s hardware business is “rotten to its core.” Apple claims that OpenAI and its subsidiary IO, along with former Apple employees, including OpenAI’s hardware chief and ex-Apple Vice President Tang Tan, are implicated in the alleged theft. Specific accusations include Tan allegedly instructing Apple engineers interviewing at OpenAI to bring “actual parts for show and tell.” Furthermore, Apple claims OpenAI circulated a “cheat sheet” designed to help recruits circumvent standard exit protocols, allowing them to remain at Apple for an additional two weeks to potentially exfiltrate confidential data. The complaint also highlights the case of a senior electrical engineer, identified as “Chang,” who allegedly exploited an authentication bug in Apple’s systems, accessed network storage from an Apple-issued laptop, and planned to retain a second company machine post-resignation, only to be discovered through communications on the monitored device.
