- Apple filed a 41-page complaint against OpenAI on Friday, July 10, 2026, in the U.S. District Court for the Northern District of California, alleging trade secret theft and breach of contract.
- The suit names OpenAI Chief Hardware Officer Tang Tan, a 24-year Apple veteran, and former engineer Chang Liu, quoting a text that reads: “LOL, I found out I can access the [network storage], so funny.”
- Apple claims more than 400 former Apple employees now work at OpenAI, and that io, the Jony Ive startup OpenAI bought for $6.5 billion, misused Apple’s confidential metal-finishing know-how.
- OpenAI responded that it has “no interest in other companies’ trade secrets,” even as its rumored iPhone-rival device now sits under a legal cloud.
More than 400 former Apple employees now work at OpenAI. On Friday, July 10, 2026, Apple told a federal judge that number is no accident. It is, the company argues, the human infrastructure of a coordinated campaign to lift the trade secrets behind Apple’s unreleased hardware and hand them to the AI lab now trying to build a phone of its own.
What Apple Actually Filed
Apple filed suit on Friday, July 10, 2026, in the U.S. District Court for the Northern District of California, accusing OpenAI of trade secret theft and breach of contract. The complaint runs 41 pages, and it names OpenAI’s device startup io, founded by former Apple design chief Jony Ive, as a co-defendant. Ive himself was not named. Apple is asking the court to bar OpenAI from using or disclosing its trade secrets, to force the return of any confidential Apple materials, and to preserve evidence before the legal discovery process begins.
The two sides are already talking past each other in public. In a prepared statement, Apple said “significant evidence has emerged suggesting individuals employed by OpenAI wrongfully took Apple’s secret and confidential information regarding our unreleased technologies, processes, and products,” adding that it would “always defend our teams’ hard work.” OpenAI, so far, has answered only with a short line posted to X on Friday: “We have no interest in other companies’ trade secrets. We remain focused on building innovative technology that empowers people everywhere.”
Trend Insight — Trade secret suits between giants are rarely just about the named individuals. Apple’s real target is the discovery process, where texts, emails, and internal documents get pulled into the open. The lawsuit is a lever to see inside a rival it says it cannot otherwise observe.
The Smoking-Gun Texts
The most vivid allegations center on Chang Liu, who spent eight years at Apple as a senior systems electrical engineer before leaving for OpenAI in 2026. Apple claims Liu failed to return his Apple-issued laptop and used it to download confidential technical documents, including specifications, engineering presentations, and proprietary project data tied to unannounced products.
“So funny”
According to the complaint, Liu messaged an Apple employee, Yu-Ting “Alyssa” Peng: “LOL, I found out I can access the [network storage], so funny.” Peng, Apple alleges, replied, “I’m ready.” Apple says Liu got in by exploiting an authentication bug, working from his former colleague’s Apple-issued computer, and that within hours of leaving the company he texted, “I still have another computer,” referring to a second Apple machine he allegedly planned to keep using. Peng later joined OpenAI herself and is not a defendant.
Trend Insight — The casual tone of these messages is the point. Apple is not just alleging theft; it is arguing that the alleged theft felt routine and low-risk to the people doing it, which is exactly how a company frames misconduct it wants a court to see as cultural rather than accidental.
“Normalized and Exemplified by Leadership”
Apple insists this is not a story about one rogue engineer. It points to OpenAI Chief Hardware Officer Tang Tan, who spent 24 years at Apple, most recently as vice president of product design for the iPhone and Apple Watch. The complaint accuses Tan of using Apple’s confidential project code names during OpenAI’s recruiting process and asking job candidates still at Apple to bring “actual parts,” “CAD/design artifacts,” and “prototypes” to interviews for “show and tell sessions.” One candidate was so surprised he reportedly admitted he “didn’t even know we could take those from the office.”
Apple further alleges that OpenAI coached departing employees on how to evade its security procedures, circulating an internal Apple document marked “Need to know” that explained how to avoid the “dreaded walkout,” the immediate removal of staff who give notice. Employees were allegedly told to alert OpenAI “asap” if Apple asked them to sign anything on their way out, and advised not to sign. With more than 400 former Apple employees now at OpenAI, Apple frames the named cases as a sample: “This is the tip of the iceberg,” the filing states, describing misconduct that is “normalized and exemplified by leadership.”
Trend Insight — Talent flows from incumbents to challengers are normal in tech. What Apple is testing here is where legal liability begins: at the moment an employee changes badges, or at the moment a competitor allegedly builds a recruiting playbook around what those employees carry in their heads and on their laptops.
Why This Is Really a Fight About a Phone
The subtext of the lawsuit is hardware. OpenAI is widely rumored to be building its first physical device, and in April 2026 analyst Ming-Chi Kuo suggested it could be a smartphone that relies on AI agents instead of apps, potentially one of the largest threats to Apple’s core business in years. OpenAI’s ambitions leaned on io, the design startup founded by Jony Ive that OpenAI acquired in 2025 for $6.5 billion. Now io is a defendant too.
Apple claims io used a proprietary metal-finishing technique after misleading one of Apple’s partners into believing it had Apple’s permission, and that OpenAI approached a battery and power supplier using “internal terminology” that “only Apple-insiders would know to ask.” The complaint’s harshest line ties the alleged theft directly to that device: OpenAI’s “nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets.” Apple says it first raised concerns in a letter to OpenAI in February 2026 and received no response, leaving it, in the filing’s words, “no choice.”
Trend Insight — For any company hiring aggressively from a rival, this case is a warning label. The exposure is rarely the resume; it is the artifact, the file, the “internal terminology” that follows a person out the door. Clean-room hiring, exit protocols, and device controls just moved up the boardroom agenda.
