Apple and OpenAI went from quiet collaborators to courtroom combatants in less than two years, and the fight now threatens both the future of the iPhone and OpenAI’s first AI device.

Early tensions and a talent drain

Through 2024–25, OpenAI began aggressively hiring from Apple, ultimately employing more than 400 former staffers, including longtime hardware executive Tang Tan and iPhone engineer Chang Liu, to build a new consumer device after its $6.5 billion acquisition of Jony Ive–linked startup io.¹² Commentators say OpenAI is defying Silicon Valley’s usual pattern of startups becoming suppliers or acquisition targets, instead positioning itself as a direct threat to Big Tech incumbents like Apple.³

The July 10 lawsuit

On July 10, Apple filed a 41-page complaint in federal court accusing OpenAI, io, Tan, and Liu of a “coordinated pattern of misconduct” to steal hardware trade secrets.⁴⁵ Apple alleges Liu kept a company laptop, exploited an unknown authentication bug, and over weeks downloaded “dozens of Apple’s confidential hardware-related files” on unreleased products and circuit-board designs while already working at OpenAI.⁶⁷

The suit paints OpenAI’s recruiting as a covert intel pipeline, claiming candidates were coached to study confidential documents, give “Technical Deep Dive” talks about Apple projects, and even bring batteries and logic boards to interview “show and tell” sessions.⁸⁹ Apple says this is just “the tip of the iceberg” and that OpenAI’s nascent hardware business is “rotten to its core” because it relies on misappropriated secrets.¹⁰

OpenAI and outside reactions

OpenAI flatly rejects the accusations, saying it has “no interest in other companies’ trade secrets” and is “not aware of any evidence that this complaint has merit,” insisting it believes in fair competition and worker mobility.¹¹¹² Legal experts note Apple is using the lawsuit to force discovery and “open OpenAI’s black box,” since it doesn’t yet know exactly what, if anything, was incorporated into OpenAI’s device designs.¹³

The filing immediately fed into broader industry drama. Elon Musk amplified a post noting that Apple and OpenAI “were partners a year and a half ago and now they’re in an all-out legal war over the post-smartphone device future,” highlighting how fast alliances have flipped in the AI race.Elon Musk (elonmusk)¹⁴

Escalation and stakes

In the days after the filing, Apple sent legal hold letters to around 40 former employees now at OpenAI, demanding they preserve documents and meet with Apple lawyers.¹⁵ Analysts say the case could delay OpenAI’s hardware launch and complicate already-delicate IPO planning, turning a trade-secret fight into a referendum on how much trust the public and regulators should place in AI companies’ handling of data and talent.¹⁶¹⁷
