Apple OpenAI Lawsuit: iPhone Maker Accuses ChatGPT Giant of Stealing Hardware Secrets

by Zaira Varghese 13. July 2026 Apple 0

The Apple OpenAI lawsuit filed in federal court has thrown the year’s fiercest talent war into open legal combat, with Apple accusing the ChatGPT maker of orchestrating a coordinated campaign to lift its most closely guarded hardware secrets. The complaint, lodged in the Northern District of California, frames OpenAI’s aggressive recruitment of Apple engineers not as ordinary job-hopping but as a deliberate scheme to extract confidential technology for OpenAI’s own consumer devices.

What the Apple OpenAI Lawsuit Actually Alleges

Apple claims the theft happened “at every level” of the departure process. According to the filing, OpenAI’s hardware chief Tang Tan, a former Apple vice president, allegedly directed Apple employees interviewing for jobs to bring “actual parts” from Apple to their interviews for “show and tell” sessions. The company also alleges that OpenAI coached departing staff on how to evade Apple’s security and offboarding processes on their way out the door.

One named engineer, Chang Liu, spent eight years at Apple as a senior systems electrical engineer. Apple says he failed to return his company-issued laptop after leaving for OpenAI and used it to download confidential technical documents covering unannounced technologies, features, and products.

Why 400 Former Employees Matter

The headline number driving the Apple OpenAI lawsuit is stark: Apple says more than 400 of its former employees now work at OpenAI, many drawn from its silicon, on-device AI, and hardware design teams. Those are precisely the groups behind Apple’s custom chips and the secretive product pipeline that has long been the company’s crown jewel.

Silicon expertise: Engineers who built Apple’s A-series and M-series chips carry deep knowledge of design tradeoffs rivals would kill for.
On-device AI: Apple’s approach to running models locally on phones is a distinct edge OpenAI would love to replicate in hardware.
Product secrecy: Apple’s culture of confidentiality means even roadmaps are treated as trade secrets.

The IPO Overhang

The timing could hardly be worse for OpenAI. The company is reportedly preparing a confidential IPO filing with Goldman Sachs and Morgan Stanley, eyeing a public debut as soon as September at a valuation near the mid-hundreds of billions. A trade-secret suit from the world’s most litigious hardware company is exactly the kind of legal overhang that makes bankers nervous weeks before a filing.

OpenAI pushed back firmly. “We have no interest in other companies’ trade secrets,” the company said in a statement. “We remain focused on building innovative technology that empowers people everywhere.”

What Happens Next

Trade-secret cases are notoriously hard to prove, hinging on whether the information was genuinely secret, whether reasonable steps were taken to protect it, and whether it was actually used. Discovery could drag on for years, and much of the juiciest evidence may end up sealed. But the reputational stakes are immediate: Apple is signaling it will fight to protect its hardware moat as OpenAI pushes deeper into physical devices.

For an industry that has normalized nine-figure poaching packages and wholesale team lift-outs, the Apple OpenAI lawsuit could set a precedent. If Apple wins even a narrow ruling, expect every major lab to tighten how it recruits from rivals — and expect a lot more Apple-issued laptops to get returned on time.
