Apple Sues OpenAI Over Alleged Trade Secret Theft

Apple filed a lawsuit against OpenAI in the District Court of Northern California, alleging the company misappropriated trade secrets and breached contracts to accelerate its development of new AI-powered hardware [2]. The litigation marks a sharp escalation in the rivalry between the two tech giants, potentially complicating OpenAI’s plans for a high-profile initial public offering [2].

The allegations of theft

Apple’s complaint centers on the actions of former employees who transitioned to OpenAI, specifically Chang Liu and hardware chief Tang Tan [2]. Apple alleges that Liu, who joined OpenAI in January 2026, failed to return a work-issued laptop and accessed a former colleague’s computer after his departure [2]. The suit claims Liu downloaded dozens of confidential hardware files, including engineering presentations and proprietary project data related to unreleased products [2].

The lawsuit further accuses Tang Tan of instructing job candidates to bring Apple parts to interviews and coaching employees on how to exit the company [2]. Apple claims Tan also emailed himself information regarding meetings with company suppliers before leaving his role [2]. OpenAI spokesperson Drew Pusateri stated that the company has "no interest in other companies’ trade secrets" and remains focused on building innovative technology [2].

A shifting competitive landscape

The legal battle follows a breakdown in a 2024 partnership that saw the two companies integrate ChatGPT into Apple products [2]. Tensions reportedly mounted in May, when reports surfaced that OpenAI was considering its own legal action against Apple for failing to sufficiently promote its products [2].

OpenAI has been aggressively recruiting talent from Apple, with at least ten engineers moving directly from the iPhone maker to the AI firm, according to an analysis of LinkedIn profiles [2]. While OpenAI has remained quiet about its hardware ambitions, reports suggest the company is developing a smart speaker and devices capable of environmental awareness [2]. These efforts are part of a broader industry push to place AI agents at the center of the consumer experience, potentially reducing reliance on traditional smartphone screens and apps [2].

What to watch

• Hardware Unveiling: OpenAI is expected to reveal its secretive AI device later this year, though the lawsuit may impact that timeline [2].
• Siri Revamp: Apple is scheduled to launch a revamped version of Siri later this year, designed to personalize answers by referencing local iPhone data [2].
• IPO Progress: Market observers are monitoring how the litigation affects OpenAI’s preparations for a potential public offering [2].

The lawsuit leaves the future of OpenAI’s hardware division in legal limbo while highlighting the intense competition to define the next generation of computing. Whether the court finds evidence of systemic intellectual property theft remains the central question that will determine the trajectory of both companies' AI strategies.
