Mark Gurman breaks down the Apple vs OpenAI lawsuit: smoking gun employee, Tang Tan's tactics, and what Apple already won

Apple vs. OpenAI: What the Lawsuit Already Won

Apple's lawsuit against OpenAI is less about what happens in court than what it has already accomplished. That's Mark Gurman's central read — and it's a compelling one.

The filing's proximate cause is a junior iPhone engineer who moved from Apple to OpenAI earlier this year, then allegedly kept accessing Apple's cloud network through a woman he had a relationship with who was still at Apple and later followed him to OpenAI. Gurman describes this as Apple's "smoking gun." But the deeper story had been building for over a year: OpenAI, led on the hardware side by Tang Tan, Apple's former head of iPhone product design, hired roughly 400 Apple employees in a compressed period spanning hardware engineering, cloud, and other divisions.

“OpenAI had been pillaging Apple's hardware engineering ranks, cloud department, many other aspects of the company for over a year. 400 people hired by OpenAI — one company hiring 400 people from another company in such a short period of time, it's absolutely insane. By just filing the lawsuit, Apple accomplished quite a bit — if you're an Apple employee thinking about joining OpenAI right now, you're going to keep your mouth shut.”

Tang Tan and the internal history

Tan left Apple at the end of 2023. John Ternus, now CEO-designate, let him stay through February 2024 because Tan's role was so embedded that Apple had to split his responsibilities across five to seven people to unwind it. Before his departure, Tan had already been working behind the scenes with Jony Ive and Sam Altman on what became IO, OpenAI's hardware subsidiary. Gurman says the origin story of IO was always an acquisition — OpenAI had already owned roughly 25% of IO for a year or more before the deal was publicly announced.

The Tan-Ternus rivalry runs through all of this. In 2020, Tan was the preferred candidate among the iPhone-side hardware team for the SVP hardware engineering role that Ternus ultimately won. Ternus had felt that Tan's priorities consistently favored the iPhone over iPad and Mac. Apple alleges that Tan then used his deep institutional knowledge — and, by implication, his willingness to play aggressively — to systematically recruit from Apple's ranks. Gurman says people who knew Tan at Apple describe him as someone who "flew very close to the sun," without necessarily crossing the line, but who did whatever it took to win.

What Apple actually achieved by filing

Even if Apple struggles to prove its trade secret claims at trial — and Gurman is skeptical, noting that hardware is highly commoditized and the complaint repeatedly acknowledges Apple doesn't yet know what IP ended up where — the lawsuit immediately creates several practical problems for OpenAI.

Any Apple employee now considering joining OpenAI will be watched closely, walked out carefully, and acutely aware of the legal exposure. Tang Tan and his team will spend significant time in depositions and working in "clean room" environments to demonstrate they haven't used Apple IP. That friction slows product development regardless of the legal outcome. Apple needed to stop the talent bleeding, and filing the suit does that without winning a single motion.

The cleaner trade secret cases, Gurman notes, tend to involve silicon. Apple successfully forced changes at Rivos, a chip startup that Meta acquired, using its proprietary chip design IP. But OpenAI's hardware is understood to be using Qualcomm and third-party chip providers, not Apple-derived silicon — which narrows Apple's strongest argument considerably.

The broader Apple picture

Separately, Gurman flags that iPhone prices are heading up sharply in September. Memory costs have made each unit $150–$200 more expensive to build, and Apple has decided to pass that through rather than compress margins. The Vision Pro, which already saw a $200 price increase due to memory, illustrates the posture: Apple does not absorb cost increases. Johnny Srouji, who now oversees hardware engineering alongside Ternus, is a silicon visionary — but whether he can drive product vision at the level the role requires remains an open question as Apple heads into what Gurman calls its biggest new product period ever.

The lawsuit is a defensive maneuver dressed as a legal action. Whether Apple wins in court is almost secondary to whether it slows down the people who know exactly how it builds things.
