The legal battle between Apple and OpenAI signals a new front in the race to build AI hardware.
SAN FRANCISCO: Apple filed a lawsuit against OpenAI on Friday in the US District Court for the Northern District of California, accusing the AI company along with its hardware unit, io Products and two former Apple employees of systematically stealing trade secrets to accelerate development of a new consumer hardware device. The filing marks a stunning reversal for two companies that stood together at Apple’s 2024 developer conference to announce ChatGPT’s integration into iOS, a partnership that has since unraveled into open legal warfare.
From Partners to Adversaries in Two Years
To understand how quickly this fell apart, it helps to look back at where things started. When Apple and OpenAI announced their alliance in June 2024, Apple paid nothing in direct licensing fees, betting instead that access to a billion iPhone users would be reward enough for OpenAI. That confidence didn’t last. As OpenAI began building its own hardware ambitions through its 2025 acquisition of Jony Ive’s startup io Products for roughly $6.5 billion, tension between the two companies started building quietly beneath the surface. By January this year, Apple had already begun shifting away, signing a deal worth about a billion dollars annually to power its next-generation Siri with Google’s Gemini model instead. That decision effectively sidelined ChatGPT within Apple’s own ecosystem well before Friday’s lawsuit made the rift public.
What Apple Actually Alleges
The complaint reads less like a routine corporate dispute and more like a workplace thriller. According to the filing, OpenAI’s chief hardware officer Tang Tan, who spent 24 years at Apple before departing to co-found io Products, allegedly used confidential internal project codenames during OpenAI’s own recruiting interviews and quizzing Apple employees still on the payroll. More strikingly Apple claims Tan directed job candidates to physically bring unreleased hardware components, things like batteries, logic boards and shielding, into interviews for what the filing calls “show and tell” sessions. Separately, Chang Liu, a former Apple electrical engineer who joined OpenAI earlier this year, allegedly retained a company laptop after leaving and later exploited a security flaw in Apple’s internal network to download dozens of confidential files covering unreleased products and manufacturing schematics. Apple also alleges that OpenAI coached departing staff on how to avoid the company’s usual practice of immediately escorting resigning employees off the premises, giving them extra time to quietly gather material before leaving.
A Talent Pipeline That Kept Flowing
None of this happened in isolation from a much broader pattern, according to Apple’s filing. The company says more than 400 of its former employees now work at OpenAI, spanning teams that once worked on camera systems, chip design, the Apple Watch and the Vision Pro headset. That kind of migration is not unusual in Silicon Valley on its own and California law generally protects employees who simply want to change jobs. What makes this case different, according to intellectual property experts, is the specific allegation that departing staff carried confidential material with them rather than just their skills and experience.
The Stakes Extend Well Beyond the Courtroom
For OpenAI, the timing could hardly be worse. The company is preparing for what could become one of the largest public listings in tech history, having confidentially filed paperwork with regulators in May while pursuing a valuation that could approach a trillion dollars. A prolonged legal battle, complete with discovery requests that could force OpenAI to hand over internal communications and development logs, threatens to complicate that process considerably. Some analysts believe the litigation could push OpenAI’s IPO timeline into 2027, potentially letting rival Anthropic go public first instead.
Why India Is Watching Closely Too
This dispute isn’t confined to Silicon Valley boardrooms either, since both companies have built substantial stakes in the Indian market over recent years. Apple has posted eighteen straight quarters of record revenue growth in India and now leads the country’s smartphone market by value, driven largely by strong demand for premium iPhone models. OpenAI meanwhile, counts India as its second-largest market worldwide with over 100 million weekly active users. The company has recently appointed former Uber India executive Prabhjeet Singh to lead its local operations from September. The company has also struck an infrastructure partnership with the Tata Group to run its models through a dedicated data center, underscoring just how much both firms now have riding on staying competitive in India, even as their relationship in the US falls apart.
What Happens Next
Apple is asking the court for an injunction to stop OpenAI from using any of the disputed material, along with an order forcing the company to return confidential documents and preserve evidence for inspection. OpenAI for its part, issued a brief statement saying it has “no interest in other companies’ trade secrets.” Whatever the eventual outcome, legal experts say the case marks a meaningful shift in how the technology industry is approaching the next phase of computing, one where the fight is no longer just about who builds the smartest AI model, but about who gets to control the physical device people actually use to reach it.
