Apple’s former AI partner OpenAI has become its most high‑stakes courtroom rival, as a fast‑escalating trade‑secrets fight now threatens the timeline for next‑generation AI hardware and a potential OpenAI IPO.

From partnership to legal war

About a year and a half after Apple and OpenAI were partners, Apple filed a 41‑page federal complaint accusing the startup of “stealing Apple’s trade secrets for the benefit of OpenAI” across product development, manufacturing, and supply‑chain operations, which it calls “one of the most valuable intellectual assets in all of American business.”¹ Coverage of the filing highlighted that Apple sees OpenAI’s alleged conduct as part of a broader scheme to shortcut development of an AI device that could rival the iPhone.²

On July 13, detailed reports laid out Apple’s most explosive claims: that ex‑engineer Chang Liu used a “rare” authentication bug to keep accessing Apple’s network for weeks after joining OpenAI, downloading “dozens of Apple’s confidential hardware‑related files,” including presentations on complex circuit boards Apple says would be “invaluable to anyone developing hardware.”³ Other allegations include “show and tell” interviews where candidates were asked to bring unreleased Apple components, and leaders who allegedly “normalized and exemplified” misconduct.⁴

OpenAI’s push into hardware – and its defense

The lawsuit lands just as OpenAI is building a consumer device business, fueled by its $6.5 billion acquisition of Jony Ive‑linked hardware startup io, a deal widely seen as driven by the desire to launch its own AI device.⁵ Apple’s complaint argues that “OpenAI’s nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets,” and asks courts for injunctions blocking OpenAI and io from using any Apple secrets.⁵

OpenAI denies the accusations. “We have no interest in other companies’ trade secrets,” a spokesperson said, adding that the company is “not aware of any evidence that this complaint has merit” and that it believes in “fair competition” and “allowing people the freedom to work wherever they choose.”⁶

Escalation: letters, discovery, and IPO jitters

Lawyers say Apple’s suit is also a way to force a look inside OpenAI’s “black box,” using discovery to learn what, if anything, was taken and whether it has been integrated into hardware designs.⁷ Apple itself describes the known conduct as “the tip of the iceberg” and predicts discovery will show misappropriation “on a scale many times greater” than the documented incidents.⁴

As Apple presses its advantage, it has reportedly sent legal letters to around 40 former employees now at OpenAI, demanding they preserve documents and meet with Apple’s lawyers,⁸ a move echoed by reports that “dozens” of OpenAI staffers have been targeted.⁹

Analysts warn the case could delay OpenAI’s hardware roadmap and complicate its path to an IPO, already under consideration for next year.¹⁰ One legal expert calls the fair‑use and trade‑secret questions facing OpenAI a “trillion‑dollar” issue for the AI industry.¹

Meanwhile, Silicon Valley watchers frame the dispute as a break with the usual unwritten code: instead of becoming a supplier or acquisition target, OpenAI has hired more than 400 Apple employees and is openly challenging Big Tech incumbents, helping explain why Apple is “fighting so hard.”¹¹

On X, Elon Musk amplified this bigger‑picture tension, sharing a post noting that “the two companies were partners a year and a half ago and now they’re in an all‑out legal war over the post‑smartphone device future. How quickly do the tables turn.”Elon Musk (elonmusk)¹²
