US judge rejects xAI trade secrets lawsuit against OpenAI

A US federal judge in California has dismissed a lawsuit from Elon Musk’s AI startup, xAI, claiming that OpenAI stole trade secrets.

Judge Rita Lin said that xAI failed to provide sufficient evidence that OpenAI engaged in misconduct or induced former xAI employees to steal proprietary information.

The lawsuit, filed in September, alleged that ex-employees took source code related to xAI’s Grok chatbot when leaving for OpenAI, but the judge noted the absence of allegations against OpenAI itself.

XAI has been given until March 17 to amend its complaint.

The company is also suing a former engineer for allegedly taking trade secrets to OpenAI. OpenAI responded by calling the lawsuit baseless and part of a broader campaign to harass the company.

The legal dispute is part of ongoing conflicts involving Musk, OpenAI, and Microsoft, including a separate lawsuit seeking damages of up to US$134.5 billion.

🧠 Food for thought

Implications, context, and why it matters.

The dismissed lawsuit is one piece of Musk’s multi-billion dollar fight with OpenAI

The trade secret case was dismissed, yet it sits within a larger dispute among Musk, OpenAI, and Microsoft. Another suit seeks up to US$134.5 billion in damages.
A separate case claims OpenAI committed fraud by walking away from its non-profit mission. That case is headed to a jury trial 1.
The judge said there is “plenty of evidence” that OpenAI leaders told Musk the original structure would stay in place 2.
The legal push runs alongside xAI’s rise as a funded rival. xAI raised $20 billion from backers including Nvidia and Cisco Investments 3.
Accounts also describe a $97.4 billion bid from xAI plus other investors to buy OpenAI in early 2025 4.

Talent fights and investor apathy shape the AI race

Claims about staff leaving underline the scramble for AI researchers. xAI says it is “hiring aggressively” to close gaps 3.
Investors appear to treat courtroom fights as background noise. They keep betting on who wins customers.
xAI closed the $20 billion round as Grok produced non-consensual sexualized images. Regulators opened probes in several countries 5.
OpenAI closed a share sale at a $500 billion valuation, while Anthropic hit $350 billion. Funding keeps flowing despite legal or ethics disputes across the sector 5.
