What Apple v OpenAI means for anyone hiring from a rival

Apple filed a lawsuit last week that alleges that OpenAI’s chief hardware officer told candidates who were still working at Apple to bring “physical hardware components” to their interviews. The complaint alleges items like batteries, logic boards, and SIPs were taken in for what the filing calls “show and tell” sessions.

Picture actually doing that – you’ve got an offer conversation going with the most talked-about company on the planet, you’re still badging into Apple every morning, and someone senior suggests you bring a component along next time. Whatever the court eventually makes of the allegation, somewhere inside it is a person who had to decide what to do with that request.

Two years ago these companies were announcing a partnership that put ChatGPT inside the iPhone. Now Apple is in court accusing OpenAI of a coordinated campaign to take its hardware secrets. Here’s what the takeaway should be for anyone in AI hiring from a competitor.

What Apple is actually claiming

These are allegations and not findings, and OpenAI has denied them flatly: it says it has “no interest in other companies’ trade secrets”.

The complaint names OpenAI, its hardware subsidiary io Products, and two people. Tang Tan spent years as a vice president at Apple, co-founded io, and now runs hardware at OpenAI. Apple says he used its internal codenames to draw confidential detail out of candidates in interviews, told serving Apple employees to bring components along, and passed around an Apple offboarding document to coach new hires on getting through Apple’s exit security.

The other name is Chang Liu, an engineer who spent eight years at Apple. The complaint says he kept his Apple-issued MacBook when he left for OpenAI in 2026, and within weeks of leaving had found a bug that left him with access to Apple’s internal file storage, and used it to download dozens of confidential documents, including a thousand-plus-page compilation of technical documents and information on unreleased products.

He’s also said to have advised at least one Apple colleague on what to study before an OpenAI interview.

One of the strangest claims is that OpenAI misled one of Apple’s exclusive industrial design partners to perform to carry out a specific trade secret metal-finishing technique, misleading the partner to believe they had Apple’s permission to do so.

The complaint also contains language that is remarkably aggressive by Apple’s standards, calling OpenAI’s hardware business “rotten to its core”. Apple wants an injunction, its materials returned or destroyed, and damages.

Why this was always coming

Apple says more than 400 of its former employees now work at OpenAI, and OpenAI’s hardware effort in particular is substantially built from Apple’s alumni network. The $6.5bn acquisition of io brought in Jony Ive, Apple’s former design chief, along with Tan and Evans Hankey, who ran Apple’s design team after Ive left. Ive and Hankey aren’t accused of anything in the filing, but you can see why Apple’s lawyers knew where to look.

And Apple has been on the losing end of this market for a while. It lost around a dozen AI researchers in 2025 to Meta, OpenAI, xAI and Cohere, including Ruoming Pang, who ran its foundation models team and left for a Meta package reported at more than $200m. Apple didn’t counter, the number was beyond what it pays almost anyone.

Pang then left Meta for OpenAI within eight months anyway, so in a year had spent time within three of the biggest AI employers globally.

In terms of a wider analysis of this kind of talent movement, it’s a reminder of something most employers are aware of – that when the profiles are this rare and the money is this aggressive, people move in clusters. And clusters look like patterns, and while nobody sues over one hire they certainly would sue over patterns.

Where the courts have previously drawn the line

Interesting to note that only three weeks before Apple filed, a federal judge threw out a case that looked superficially identical: xAI’s trade secrets suit against OpenAI, which accused it of orchestrating a hiring push to pull confidential information out through departing engineers. Judge Rita Lin dismissed it without leave to amend.

Her reasoning was that asking a candidate about their past work was indicative of routine hiring, not inducement. Working out where someone would fit, also routine. Even a new hire arriving with confidential things in their head: “mere possession of trade secrets is not sufficient”. Rule the other way, she noted, and every employer is at risk every time they ask about a candidate’s experience.

But in this case, everything Apple alleges is active. Directing candidates to bring parts, using codenames used to pull out specifics, a circulated offboarding document, and coached exits. Apple isn’t claiming OpenAI passively benefited from what its hires happened to know, but claiming OpenAI ran the operation.

Can they prove it? That’s a different question, and discovery is going to be uncomfortable in both directions. But if you hire people, the map is pretty clearly drawn. Interviewing someone hard on their capability: safe. Touching on their former employer’s materials or specifics: not.

None of this is new so much as re-learned. Waymo v Uber set the price back in 2018: 0.34% of Uber’s equity, about $245m, to settle claims built on 14,000 files an engineer downloaded before leaving.

What this means if you’re hiring, or moving

If you’re hiring from competitors, the line the courts have drawn runs straight through your interview room. Ask about capability, judgement and how someone thinks. Don’t ask about artefacts, specifics, or anything with a codename on it.

Structure the process, write it down, brief everyone on the panel. And if a candidate volunteers confidential material, shut it down and record that you did. The xAI ruling favours employers who ran a routine process, but it does nothing for employers who can’t show their process was routine.

If you’re the candidate, the blunt version is your exit is even more a part of your reputation now. Give the laptop back. Don’t take files “just in case”, even the harmless-feeling ones. The people named in these cases are engineers, not top execs, and their names sit in federal filings that will outrank their LinkedIn profiles for years.

Speaking with a prospective employer on how they’ll handle their move is fair to ask in an interview process, and it’s a fair question, because a company that’s casual with your old employer’s IP will be casual with you.

Where this goes

Apple v OpenAI will run for years, and most of what’s alleged will be fought line by line. The pattern underneath it won’t wait, talent is the asset these companies are fighting over, the courts are now part of the fight, and every hiring process between competitors runs a little in its shadow.

Most companies will never be named in a filing like this. But every one of them is now hiring people who’ve read about it or known first hand people who have. It is basically impossible to not step into competitor territory when hiring, so working out how to bring senior people across from a competitor without importing anyone’s problems is paramount.
