Apple sued OpenAI on Friday, alleging that the company systematically stole iPhone technology and trade secrets through more than 400 former Apple employees, including senior hires like hardware chief Tang Tan. The lawsuit alleges that Tan and other former Apple staff emailed confidential supplier information to personal accounts and used knowledge of Apple's proprietary designs to help OpenAI build AI devices. The case arrives amid public sparring between Elon Musk, who co-founded OpenAI, and CEO Sam Altman over the company's commercial direction.

Apple filed a lawsuit against OpenAI on Friday, alleging that the company engaged in coordinated misconduct by stealing iPhone technology through former Apple employees. The suit names Tang Tan, OpenAI's hardware chief and former Apple vice president of product design, and Chang Liu, a former Apple electrical engineer, as having colluded to take confidential information. Apple claims that Tan emailed himself supplier information before joining OpenAI and asked prospective OpenAI candidates still at Apple to bring "actual parts" to interviews, while Liu used a former colleague's Apple-issued laptop to access the company's network and downloaded hardware files on unreleased products. Meanwhile, Elon Musk, who co-founded OpenAI, publicly attacked CEO Sam Altman on X over the weekend, accusing him of "scamming," and Altman fired back at Musk's SpaceX over space-based data center plans.
Why it matters
The lawsuit exposes potential risks for companies that hire talent from competitors, particularly in hardware and AI development. Apple alleges that OpenAI currently employs more than 400 former Apple workers, suggesting a broad pattern rather than isolated incidents. For businesses investing in proprietary hardware or AI products, the case underscores the stakes of protecting trade secrets and the legal exposure of hiring former employees who may retain access to confidential information. The public spat between Musk and Altman also reflects deeper tensions over OpenAI's shift from nonprofit to commercial operations—Musk has separately lost a lawsuit against OpenAI and its backer Microsoft over the company's direction.
What to watch
Apple's court filing on Friday marked the formal launch of the legal action; OpenAI has stated it has "no interest in other companies' trade secrets" and remains focused on building AI devices. The suit's outcome could set precedent for what constitutes misappropriation of trade secrets in AI and hardware development.
The lawsuit between Apple and OpenAI represents a significant escalation in competitive tensions within AI and hardware development. Apple's allegation of "coordinated pattern of misconduct at an institutional level" suggests the company views the hiring of former employees and their alleged transfer of confidential information not as isolated incidents but as a systematic practice. The specificity of the allegations—from Tan's emails of supplier lists to Liu's network access using a colleague's credentials—paints a detailed picture of how proprietary information may have moved from Apple to OpenAI.
The case also occurs against the backdrop of public disputes between Musk and Altman over OpenAI's evolution. Musk, who co-founded the organization expecting it to remain a nonprofit, has already lost a separate lawsuit against Altman, Brockman, and Microsoft over the company's shift to a for-profit structure. His weekend attack on Altman, accusing him of "scamming," reflects lingering grievances about OpenAI's commercial direction. Altman's retort about SpaceX's space-based data centers suggests tensions between the two figures extend beyond OpenAI's governance to competitive technology bets.
For businesses in AI and hardware sectors, the Apple-OpenAI dispute raises practical questions about the enforceability of trade secret protections when talent moves between companies. With Apple citing the employment of more than 400 former staff at OpenAI, the lawsuit may become a test case for whether large-scale hiring of competitors' employees—even absent explicit non-compete agreements in some jurisdictions—can expose a company to liability for misappropriation of confidential information.
