In a dramatic reversal of their high-profile partnership, Apple filed suit against OpenAI in Northern California federal court on July 10, 2026, alleging a systematic, coordinated campaign to steal Apple's most sensitive hardware trade secrets.
The complaint names Tang Tan — a former Apple VP of Hardware and the man who oversaw Apple Silicon's physical design — as the alleged architect of the scheme. According to Apple, after Tan joined OpenAI as a senior hardware executive, he directed recruiting teams to target Apple hardware engineers specifically, and coached departing employees on how to evade Apple's offboarding security procedures.
The "Show and Tell" Interviews
The most striking allegation is what Apple describes as "show and tell" job interviews. Apple claims OpenAI recruiters instructed candidates to physically bring Apple hardware prototypes, unreleased components, or internal design documents to their interviews — framing it as a way to demonstrate their work. In at least one documented case, a hire allegedly walked out of Apple's campus with an actual company laptop.
Apple frames this not as a few bad actors but as a structured, repeatable playbook applied across hundreds of hires over roughly 18 months. The suit seeks both injunctive relief and damages.
A Partnership Turned Legal War
The lawsuit is a jarring turn for two companies that announced a deep integration at WWDC 2024, embedding ChatGPT directly into iOS, iPadOS, and macOS. That deal — celebrated as a landmark moment for on-device AI — now sits in an awkward legal limbo. Apple has not announced whether it intends to unwind the integration, but the suit's language leaves little room for goodwill.
OpenAI has not yet filed a formal response, but a spokesperson told press the allegations are "without merit."
Why This Matters Beyond the Headlines
The case touches something deeper than corporate rivalry. Apple Silicon — the M-series and forthcoming generations — represents one of the most sophisticated chip architectures in consumer hardware. If the suit's allegations are proven, the implications extend well past this litigation: it would suggest that AI hardware ambitions are now intense enough to drive systematic IP extraction from the world's most secretive hardware company.
For the broader AI industry, the lawsuit is a signal that the race to build custom silicon for AI inference has reached a level of competition where normal competitive boundaries are being tested. Whoever controls the next generation of efficient inference chips controls the economics of AI at scale — and apparently, some players are willing to take serious legal risks to get there faster.
The case is expected to move to discovery within 90 days. Apple is requesting a jury trial.
