Apple sues OpenAI over alleged hardware trade‑secret theft

Apple sued OpenAI in federal court on July 10, 2026, alleging a systematic effort to steal confidential iPhone hardware designs, a move that could stall OpenAI’s push into consumer‑device AI and intensify legal battles between the two tech giants【2】.

Allegations and legal framing

Apple’s complaint claims that former Apple engineers, now at OpenAI, were encouraged to bring proprietary hardware information to interviews, effectively “stealing” trade secrets tied to OpenAI’s consumer‑device ambitions. The suit specifically names Tang Tan, OpenAI’s hardware chief who spent 24 years at Apple, and engineer Chang Liu as participants in the alleged scheme【2】. Apple describes the operation as “at every level,” suggesting a coordinated campaign rather than isolated incidents. OpenAI has responded only that it is “reviewing the filing” and maintains it has “no interest” in competitors’ trade secrets, leaving the allegations untested in court【2】.

Context and market impact

The lawsuit follows OpenAI’s $6.5 billion acquisition of IO Products, a startup co‑founded by former Apple design lead Jony Ive and other ex‑Apple executives, underscoring OpenAI’s aggressive hardware push. The filing also notes that OpenAI has hired more than 400 former Apple employees, highlighting the depth of talent migration from Apple to its AI rival【1】. Apple’s stock closed at $315.32, down 0.28% on the day, but remains up 16.2% year‑to‑date, indicating that while the legal news nudged the share price, broader investor sentiment stays positive【2】.

The timing coincides with OpenAI’s confidential filing for an IPO targeting a valuation north of $1 trillion, a milestone that could be jeopardized by prolonged litigation. Market bettors currently assign a 51.5% probability to a $1 trillion year‑end valuation, reflecting uncertainty around the company’s valuation trajectory amid the lawsuit and other partnership strains【2】.

Public sparring

Elon Musk amplified the dispute on X, labeling OpenAI CEO Sam Altman “Scam Altman” and accusing him of “stealing all of Apple’s phone technology”【2】. Altman retorted by critiquing Musk’s own space‑data‑center ambitions and called Apple an “s‑tier company,” while emphasizing he is “not afraid” of the lawsuit【2】. The exchange underscores how the legal battle has become a public arena for broader tech rivalries, potentially influencing investor sentiment and partner relationships.

What to watch

• Court proceedings: Monitor the docket for motions or settlement talks, which could affect OpenAI’s IPO timeline.
• OpenAI hardware rollout: Look for any delays or redesigns of the consumer‑device projects tied to the alleged stolen designs.
• Apple‑OpenAI partnership: Track whether Apple resumes or terminates its prior integration of ChatGPT on iPhones, signaling the lawsuit’s impact on product collaborations.

The lawsuit pits Apple’s aggressive protection of its hardware IP against OpenAI’s rapid talent acquisition strategy, raising questions about how legal pressures will shape the AI firm’s hardware ambitions and its upcoming public offering.
