Reports emerged this week that the U.S. Department of Justice is formally investigating whether NVIDIA structured its $20 billion licensing agreement with AI chip startup Groq to deliberately dodge antitrust review — a probe that threatens to redefine the rules of mega-deals across the entire AI industry. NVDA shares slid to a daily low of $217.20 on September 10 , down from $230.36 just days earlier , as investors priced in a new tier of regulatory risk for the world's most valuable chipmaker.
The Deal That Wasn't Technically a Deal
Investigators opened the probe shortly after the December 2025 announcement and are now examining whether NVIDIA structured the arrangement as a license, rather than a takeover, specifically to skip the antitrust review a normal merger would trigger.
NVIDIA paid roughly $20 billion for a non-exclusive license to Groq's inference chip technology, hired away founder Jonathan Ross and much of the senior team, while Groq kept operating on paper under a new CEO.
If found at fault, NVIDIA could be fined.
Washington Is Watching the Playbook, Not Just the Player
Earlier this year, senators urged regulators to scrutinize large tech arrangements that could work like mergers while avoiding the usual filing requirements, arguing such deals consolidate talent and resources without triggering standard review.
Federal rules state that transactions structured to avoid filing requirements can be disregarded, with regulators instead judging the deal's substance. This means any forced unwinding or restructuring could strand the $14.4 billion in goodwill NVIDIA already booked on its balance sheet, along with $2.5 billion in intangible assets tied to the deal.
Market Dominance Makes NVIDIA a Bigger Target
NVIDIA dominates the AI data center chip market with an estimated 81% share in 2026, according to IDC, with no competitor holding more than about 10%. That concentration gives regulators a clear narrative: a near-monopolist absorbing a rival's technology and talent. Senators Warren and Blumenthal characterized the deal as a potential illegal attempt to evade antitrust laws that could entrench NVIDIA's ~90% GPU market share.
NVIDIA's Defense Has Teeth — But So Does the Risk
By late 2025, Groq faced financial pressure, had conducted layoffs, and was struggling to secure resources to scale production. NVIDIA argues it preserved a failing competitor. Groq retained its technology rights and raised $650 million in June 2026 to rebuild as an independent cloud provider — a fact that supports NVIDIA's case. Yet with fiscal 2026 revenue of $215.9 billion (up 65% year-over-year) , the company can absorb fines. What it cannot easily absorb is a precedent that blocks future "license-and-hire" deals — the very strategy powering its expansion beyond GPUs into inference hardware. Shareholders should watch whether this probe produces a fine or a framework.
