Former Groq Engineers Sue Over Nvidia $20B AI Chip Deal

Nvidia’s reported $20 billion agreement with AI chipmaker Groq is facing a new challenge from two people who helped build the technology at its centre. Former Groq engineers and shareholders Benjamin Serebrin and Joshua Rubin have sued over the December 2025 deal, arguing that its unusual licensing-and-hiring structure left ordinary shareholders shortchanged.

The lawsuit was filed in Delaware on October 2, according to a Financial Times report published on Monday. It alleges that Groq’s leaders and affiliated investors captured benefits that were not shared fairly with other stockholders. These are allegations, not findings by a court, and the filing does not by itself establish that either company acted unlawfully.

The original arrangement was not presented as a conventional takeover. Groq described it as a non-exclusive technology licence, while founder Jonathan Ross and a large part of its technical team moved to Nvidia. Groq remained a separate company. That combination is precisely why the transaction has attracted attention: a buyer can gain technology and the people who know how to use it without buying all the shares in a startup.

For an engineer who holds company stock, the distinction is more than legal vocabulary. In an ordinary acquisition, shareholders generally know the purchase price and the terms on which their shares are being bought. A licence, recruitment package and other payments can distribute value through several channels. The plaintiffs say that made the outcome unfair to shareholders outside the group negotiating the deal. The defendants will have an opportunity to contest that account.

Groq developed processors designed to run AI models quickly at the inference stage, when a trained system responds to users. That capability is strategically valuable as AI companies try to reduce the cost and delay of serving millions of requests. Nvidia, already dominant in AI training hardware, had reason to want both Groq’s designs and the specialists behind them.

The deal has also drawn wider scrutiny. As the competition questions around Nvidia and Groq have grown, the shareholder case adds a different issue: whether a transaction that leaves a company legally independent can nevertheless transfer most of its value elsewhere. Antitrust authorities and a Delaware corporate court would examine different legal questions, so one process should not be confused with the other.

This is not just a dispute about a headline figure. The reported $20 billion value, the actual flow of money and the rights attached to different classes of shares are all important to understanding who benefited. Those details will matter as the court considers the complaint and any response. The public description of a deal as ‘non-exclusive’ does not settle how its economics should be treated.

AI companies have increasingly used licensing agreements and talent moves to secure technology quickly. The Groq case could become a useful test of how far that playbook can go before employees and smaller shareholders demand the protections they would expect from a sale. For now, the suit is at an early stage, and the central claims remain contested.
