Justice Department opens formal antitrust probe into Nvidia's $20 billion Groq deal

The Justice Department has opened a formal antitrust investigation into whether Nvidia structured its $20 billion licensing agreement with AI chip startup Groq specifically to dodge the government review that ordinary corporate acquisitions must undergo, according to a report first published by The New York Times and confirmed by wire services on Wednesday. The department's antitrust division has sent Nvidia a formal demand for information, the paper reported, escalating an inquiry that began quietly within days of the deal's announcement last December.

The arrangement at the center of the probe let Nvidia absorb the technology and top talent of its most credible rival in low-latency AI inference chips without buying the company outright — a structure critics call a "reverse acquihire." Regulators are now testing, in a live case, whether that structure is a legitimate licensing deal or a disguised merger that should have triggered a Hart-Scott-Rodino filing and the waiting period that comes with it.

The numbers

Nvidia and Groq announced their agreement on December 24, 2025, describing it publicly as a non-exclusive licensing agreement for Groq's inference technology rather than a takeover. Nvidia paid roughly $20 billion in cash for a perpetual license to Groq's patent portfolio and software, a figure most outlets have used since the announcement; the Times' account of the current investigation put the core license payment closer to $17 billion, with the remainder tied to related commitments. Either way it stands as Nvidia's largest transaction on record, dwarfing anything else in the company's history.

Groq had been valued at roughly $7 billion in a funding round completed before the deal — meaning Nvidia paid close to three times that figure for a license and a talent raid rather than the company itself. Groq's founder and chief executive, Jonathan Ross, and its president, Sunny Madra, both moved to Nvidia as part of the agreement, along with a substantial share of Groq's engineering staff. Groq's own chief financial officer, Simon Edwards, was elevated to chief executive of what remains of the company, which continues to run its GroqCloud inference service as a nominally independent business. Nvidia itself, now valued at roughly $5.4 trillion, disclosed in its annual report to the Securities and Exchange Commission that it "entered into an intellectual property license arrangement with Groq, Inc., or Groq, that required significant, nonrefundable payments" — the company's own regulatory acknowledgment that real money, not stock or contingent consideration, changed hands.

How we got here

Deals like this one have become a recognizable pattern across the AI industry over the past two years: a cash-rich incumbent pays a smaller rival's investors to license its technology, hires away its founders and best engineers, and lets a hollowed-out shell keep operating under its own name. The structure avoids the automatic merger review that a straightforward acquisition would trigger, because no company is technically being bought and no controlling stake changes hands. Regulators at the Federal Trade Commission and Justice Department have grumbled about the tactic for months without bringing a case that tests it directly — until now.

Groq's Language Processing Units were widely seen as the most serious near-term threat to Nvidia's dominance in the fast-growing market for AI inference — running trained models cheaply and quickly, as opposed to training them, which remains Nvidia's stronghold. Removing that competitive pressure, rather than simply acquiring useful engineering talent, is precisely what antitrust enforcers are examining. The Justice Department's inquiry began "shortly after" the December announcement, according to the Times, and has grown from informal questions into a formal information demand over the intervening nine months — a timeline that itself signals the department sees enough substance to keep pressing rather than let the matter quietly close.

Who's watching, and what they're saying

Congress moved faster than regulators did. In March, Democratic Senators Elizabeth Warren of Massachusetts and Richard Blumenthal of Connecticut sent Nvidia chief executive Jensen Huang a letter demanding he explain the deal's structure and its consequences for competition, giving the company until early April to respond.

"In practice, NVIDIA's acquisition of Groq's assets allows NVIDIA to consolidate and further entrench its market share... By licensing its technology and hiring its most important employees, NVIDIA has effectively acquired Groq in all but name," Senators Elizabeth Warren and Richard Blumenthal wrote to Nvidia chief executive Jensen Huang.

Nvidia has firmly rejected the idea that anything improper occurred. "The Groq story is a prime example of the American system working as designed to promote innovation, reward entrepreneurs, and benefit consumers," a company spokesperson said in response to the DOJ report. Groq and the Justice Department both declined to comment when contacted by reporters. Wall Street's early reaction to the original deal was notably more skeptical of the "non-exclusive" framing than Nvidia's public messaging: Bernstein analyst Stacy Rasgon argued at the time that structuring the transaction as a license rather than a purchase served mainly to "keep the fiction of competition alive."

Coverage of the investigation has also noted that the DOJ's interest follows complaints from rival chipmakers and cloud providers, who argue the deal let Nvidia quietly neutralize a competitor in the exact market — cheap, fast inference — where challengers had their best shot at chipping away at its grip, a detail first surfaced in reporting on the regulatory scrutiny building against Nvidia. The company already faces separate antitrust attention over its dominant position in AI training chips generally; the Groq matter adds a second, more novel front focused specifically on deal structure rather than market share.

• Nvidia — the company under investigation, its largest-ever transaction now under formal review
• Groq — reduced to a shell operating GroqCloud under new leadership after losing its founder, president and core engineering team
• Rival AI-chip and cloud companies — whose complaints reportedly helped prompt the inquiry, and who could benefit if the structure is curtailed industry-wide
• Other tech giants using similar "reverse acquihire" licensing deals — whose own arrangements could face fresh scrutiny depending on the outcome

What happens next

Investigators told the Times they do not currently expect to seek unwinding of the transaction, but say Nvidia could face fines if the department concludes the deal was deliberately engineered to evade review. That would make this less a fight over Groq itself — whose technology is already being folded into Nvidia's product roadmap — and more a test case for how the Justice Department intends to treat an entire category of AI-industry transactions going forward. A finding against Nvidia would put every company that has copied the same playbook on notice; a finding that clears the deal would effectively bless the structure as a loophole other giants can keep using.

For now, the investigation remains open with no set timetable for a decision, and Nvidia has given no indication it will alter its integration of Groq's technology while the inquiry proceeds. The company said in August that server racks built around the licensed Groq architecture were on track to go live before the end of 2026, a rollout regulators are watching just as closely as the underlying legal question of whether the deal should have been reviewed in the first place.
