Groq engineers sue board over Nvidia's $20B deal
Chip money is colliding with employee equity to start the week — alongside a Cerebras rebound and Europe's newest robotics unicorn.
Two former Groq engineers have sued the company in Delaware, alleging the $20 billion Nvidia deal that absorbed most of the company short-changed rank-and-file employees. Benjamin Serebrin and Joshua Rubin filed the suit in Delaware around October 3–4, according to the Financial Times, which first reported it: the claim is that common shareholders "cashed out cheaply" while top Groq employees were allowed to take a discount on their own shares and be paid separately for following the technology to Nvidia. The structure under challenge is the December 2025 "non-exclusive" arrangement — roughly $17 billion in licensing fees plus a $3 billion Nvidia stock pool, with around 200 Groq engineers hired over, about 90% of the company. The allegations are unproven, but they land on top of the Justice Department's existing antitrust probe of the same deal, which we covered in September — DOJ probes whether Nvidia's Groq deal dodged antitrust review. When a deal that regulators already question also draws shareholder litigation, the "non-exclusive licensing" framing starts to look less like deal structure and more like a defense that has to be argued in two rooms at once.
Cerebras stock rebounded about 6% on Monday after Sam Altman publicly vouched for the partnership. "Cerebras is a close partner, and we have a deep engagement pushing on the frontiers of speed," Altman posted on X on Friday, after a week in which the stock fell roughly 19.5% on the news that OpenAI will run GPT-6.1 Sol's "Ultrafast" mode on Nvidia GPUs instead of Cerebras chips. The reassurance still leaves the shares around $177 — near half their May IPO-era peak, with a market value just over $39 billion versus $95 billion at debut — and Citi says it is "too early to read much into it," keeping its revenue outlook unchanged.
Germany's RobCo has become Europe's newest robotics unicorn, crossing a $1 billion valuation through a secondary share sale that let long-standing employees cash out. The Munich-based maker of autonomous industrial arms sold about $40 million of shares, doubling its roughly $500 million valuation in nine months, with existing backers Sequoia and Lightspeed joining new investors Cherry Ventures and European Tech Collective, the Wall Street Journal reports. RobCo raised a $100 million Series C in January and is preparing to launch Alfie, its autonomous factory robot, commercially in March 2027 while expanding in the US, its fastest-growing market.
What to watch: Cerebras lockup expirations on October 14 and 28, and whether the Groq suit pulls more discovery into the Nvidia deal.
When a deal's own employees sue over how it was structured, is the "non-exclusive" framing still credible? Tell us in the comments.
