Apple and OpenAI spent 2024 announcing a partnership. This month, they’re in federal court instead.
Apple filed a lawsuit against OpenAI on July 10 in the US District Court for the Northern District of California, alleging trade secret theft and breach of contract. According to the complaint, OpenAI and several individuals — including its chief hardware officer, a former senior Apple product-design executive — engaged in what Apple describes as “a coordinated pattern of misconduct at an institutional level,” aimed at helping OpenAI build its own consumer hardware.
This is a significant reversal. Apple integrated ChatGPT into Apple Intelligence in 2024, and the two companies were widely seen as allies in AI. This lawsuit suggests that relationship has curdled — though, notably, Apple hasn’t said the ChatGPT integration itself is affected.
What the lawsuit actually alleges
Court filings are one side of a story, told by the party bringing the case — so everything below is Apple’s account, not a finding of fact. With that caveat, here’s what Apple’s complaint claims:
- Tang Tan, OpenAI’s chief hardware officer and a 24-year Apple veteran who led iPhone and Apple Watch product design, allegedly emailed himself information about Apple’s suppliers before he left the company, and allegedly used internal Apple codenames when interviewing job candidates who still worked at Apple — a tactic Apple says was designed to extract more confidential information.
- Chang Liu, a former senior Apple electrical engineer who joined OpenAI in January 2026, allegedly failed to return an Apple-issued laptop and used it to download confidential technical documents, according to the complaint.
- A supplier, Apple claims, was approached by OpenAI using Apple’s confidential information about power and battery components, and was reportedly asked to carry out a proprietary Apple metal-finishing technique while “misleading the partner to believe they had Apple’s permission to do so.”
- Job candidates, Apple alleges, were directed by Tan to bring actual Apple hardware components to OpenAI interviews for what the complaint calls “show and tell” sessions — with one candidate reportedly surprised that Apple parts could even be taken off-site.
Apple’s complaint also names io Products — the hardware venture OpenAI acquired for $6.5 billion, built around former Apple design chief Jony Ive — though Ive himself is not named as a defendant. Apple says more than 400 former Apple employees are now at OpenAI, and frames the alleged conduct as reaching “at every level, from members of its Technical Staff to its Chief Hardware Officer.” Apple is asking the court to bar OpenAI from using any of its trade secrets and to require the return of confidential materials.
What OpenAI says
OpenAI has denied the allegations. “We have no interest in other companies’ trade secrets,” a company representative said in a statement. “We remain focused on building innovative technology that empowers people everywhere.” OpenAI hasn’t detailed what its rumored consumer hardware device actually is — CEO Sam Altman said in November 2025 that the company had finished its first prototypes, and OpenAI’s chief global affairs officer reportedly told Axios at Davos that a device could arrive in the first half of 2026.
Worth noting: this isn’t purely one-directional. Axios reports OpenAI had separately been preparing its own legal action against Apple over their partnership, reportedly weighing a breach-of-contract notice, according to earlier reporting from Bloomberg and the New York Times. That context suggests friction between the two companies predates this filing.
Why this matters beyond the courtroom
This is unusually direct, even for Silicon Valley. Big tech companies poach each other’s talent constantly — that’s not news. What makes this suit notable is that Apple is alleging a coordinated effort, not just “a rogue employee took some files on the way out,” and it’s happening between a company OpenAI is contractually tied to through Apple Intelligence and a company that may soon compete with the iPhone directly. If OpenAI is genuinely building consumer hardware, as Altman has suggested, this case will shape how much scrutiny that device gets before it ever ships. For context on how Apple’s AI relationships are already shifting, see our coverage of Apple bringing Alibaba’s Qwen AI to iPhones in China — the same week this lawsuit is playing out, Apple’s AI partnerships are clearly in flux on multiple fronts.

This is very early in the case — filed July 10, with discovery still ahead. Expect this to develop over weeks or months, not resolve quickly. We’ll update as it moves through the courts.

Frequently Asked Questions
Did Apple prove OpenAI stole its trade secrets?
No — as of publication, this is a lawsuit, not a court ruling. Apple has filed allegations in the US District Court for the Northern District of California, and OpenAI has publicly denied them. Courts haven’t made any findings yet; that will happen through the discovery process and, potentially, trial.
Does this affect ChatGPT in Apple Intelligence?
Apple hasn’t said the lawsuit changes its ChatGPT integration, and both companies’ commercial partnership appears to be continuing for now. The dispute is specifically about OpenAI’s alleged hardware ambitions, not the existing software partnership.
Is OpenAI actually making a physical device?
OpenAI hasn’t officially detailed a product. CEO Sam Altman said in November 2025 that early prototypes existed, and the company acquired Jony Ive’s hardware startup io Products in a $6.5 billion deal. A device has been rumored for release sometime in 2026, but OpenAI has not confirmed specifics.
| ✍️ Editor’s Observation
What stands out to me isn’t the allegations themselves — talent moving between rival companies and disputes following them is an old story in tech. It’s the specificity. Codenames used in interviews, a named metal-finishing technique, actual hardware parts allegedly brought to job interviews — these are the kinds of granular details that make a complaint either very strong or very risky to have filed if they don’t hold up. We’ll know a lot more once OpenAI formally responds in court. Until then, this is Apple’s account, not the final word. |
