Warren questions Nvidia's $20bn Groq deal as antitrust scrutiny mounts
Senators warn licensing agreement may be structured to evade regulatory review, raising fresh challenges for the AI chip giant
Senator Elizabeth Warren has questioned whether Nvidia's $20 billion agreement with artificial intelligence chip startup Groq is structured to evade antitrust review, placing the company's dominant market position under renewed political scrutiny.
The Massachusetts lawmaker, joined by Senator Richard Blumenthal, sent a letter to Nvidia chief executive Jensen Huang on March 23 demanding an explanation of the December 2025 transaction, according to a press release from Warren's office. The senators allege the arrangement amounts to a "reverse acquihire"—acquiring a competitor's key assets and personnel without formally purchasing the company itself.
"By licensing its technology and hiring its most important employees, NVIDIA has effectively acquired Groq in all but name," the senators wrote. "We are concerned that this takeover could stifle competition, further entrenching NVIDIA's dominance in the AI chip industry and ceding our technological leadership to China."
Nvidia shares fell 0.3% to $175.20 on Tuesday, giving the company a market valuation of $4.27 trillion. The stock has traded in a range between $86.60 and $212.17 over the past 52 weeks, reflecting investor volatility around regulatory developments in the artificial intelligence sector.
The Groq transaction, structured as a licensing agreement rather than an acquisition, granted Nvidia a non-exclusive license to Groq's chip technology while bringing CEO Jonathan Ross and other key personnel into the company. Groq continues to operate as an independent entity, according to reports of the deal structure.
This arrangement has allowed Nvidia to avoid premerger notification requirements typically triggered by acquisitions exceeding $119.5 million, a threshold designed to give regulators time to assess competitive impacts before deals close. The senators warned that Nvidia is pursuing a strategy that could become increasingly common across the technology industry if left unchecked.
The regulatory pressure comes at a critical moment for Nvidia, which already controls approximately 90% of the market for graphics processing units used in AI training and inference. The company on March 16 announced a new inference processor incorporating Groq's technology, signaling rapid integration of the licensed assets.
The senators highlighted a pattern of behavior, noting Nvidia's similar licensing deal with chip interconnect startup Enfabrica in September 2025. They also referenced previous antitrust investigations by the Department of Justice and regulators in the European Union and United Kingdom, indicating mounting global concern about Nvidia's market power.
Competitive impacts are already evident. OpenAI had reportedly been evaluating Groq's energy-efficient inference chips as an alternative to Nvidia's offerings but "shut down" those discussions after Nvidia's licensing agreement was announced, according to the senators. The ChatGPT creator subsequently increased its chip purchases from Nvidia.
"By further consolidating NVIDIA's control over the AI chip industry, the Groq deal limits consumer choice and innovation, which will ultimately raise prices and threaten domestic firms' ability to compete with China," Warren and Blumenthal wrote.
The lawmakers have given Huang until April 3 to respond to questions about the deal's structure and strategic rationale. The Federal Trade Commission and Department of Justice retain authority to review such transactions for antitrust violations even when formal notification thresholds are not met.
Analysts remain broadly bullish on Nvidia despite the regulatory headwinds, with 60 of 62 analysts rating the stock a buy or strong buy and an average target price of $269.58, according to market data. The company reported 95.6% year-over-year earnings growth in its most recent quarter, with profit margins of 55.6% reflecting its pricing power in the AI chip market.
The increasing scrutiny of unconventional deal structures comes as Washington regulators intensify their focus on the technology sector. The FTC has signaled growing concern about tactics that allow dominant companies to consolidate market share without triggering traditional merger review processes.
Nvidia did not respond to requests for comment on the senators' letter or the specifics of the Groq agreement.
