Apple Sues OpenAI Over Alleged Theft of Hardware Trade Secrets

Apple filed a lawsuit against OpenAI in federal court on July 10, 2026, alleging a systematic campaign to misappropriate confidential hardware designs and supply chain strategies to bolster the AI company’s consumer device ambitions [3]. The litigation marks a sharp reversal in a relationship that previously saw the two companies integrate ChatGPT into the iPhone ecosystem [2].

Allegations of a Coordinated Scheme

The complaint details a pattern of behavior involving two former Apple employees now employed by OpenAI: Tang Tan, the former Vice President of Product Design for iPhone and Apple Watch, and Chang Liu, a former senior system electrical engineer [2]. Apple alleges that Tan methodically emailed himself internal industry summaries and supplier information before his departure, while also encouraging job candidates to bring proprietary Apple parts to interviews at OpenAI for "show and tell" sessions [2].

Further, the company claims that Liu retained an Apple-issued laptop after his departure and utilized an authentication bug to access Apple’s internal network, where he allegedly downloaded dozens of confidential hardware files [2]. Apple asserts that this information is being used to jumpstart OpenAI’s hardware division, which includes the assets acquired through its $6.5 billion purchase of Jony Ive’s startup, io Products [2]. Apple stated it attempted to resolve these concerns privately in February, but received no response from OpenAI [1].

Market and Competitive Implications

The legal action arrives at a critical juncture for OpenAI, which has confidentially filed for an initial public offering targeting a valuation exceeding $1 trillion [3]. While OpenAI spokesperson Drew Pusateri stated the company has "no interest in other companies’ trade secrets," the lawsuit introduces significant uncertainty for investors, with Polymarket bettors currently assigning only a 52% probability to the company reaching its target valuation [3].

The dispute has also drawn public commentary from Elon Musk, who criticized OpenAI’s leadership on X, while OpenAI CEO Sam Altman countered by questioning the viability of SpaceX’s orbital data center projects [3]. For Apple, the lawsuit serves as a protective measure for its intellectual property as it navigates a competitive landscape where more than 400 former Apple employees are now employed by OpenAI [2]. The tension coincides with Apple’s recent, long-delayed overhaul of Siri, which was designed to integrate more deeply with AI capabilities [2].

What to watch

• Court Proceedings: Monitor for OpenAI’s formal response to the allegations in the U.S. District Court for the Northern District of California [2].
• IPO Progress: Watch for updates on OpenAI’s confidential IPO filing and whether the litigation impacts the company’s valuation or timeline [3].
• Hardware Strategy: Observe if OpenAI provides further details on its "non-traditional" consumer hardware project, which remains the primary focus of Apple’s trade secret claims [1].

The lawsuit forces a public confrontation between two of the most influential players in the AI race, potentially complicating OpenAI's transition from a software-focused entity to a hardware developer. Whether the legal discovery process reveals a systemic breach or remains a dispute over talent mobility will likely determine the long-term impact on both companies' product roadmaps.
