DOJ Launches Formal Antitrust Probe into Nvidia's Groq Deal

The U.S. Department of Justice has formally opened an antitrust investigation into Nvidia's licensing arrangement with AI chip startup Groq. [2] The agency sent Nvidia a formal demand for information regarding the December 2025 agreement, which brought Groq founder Jonathan Ross and president Sunny Madra to Nvidia. [2] Reports vary on the deal's exact size, placing it between $17 billion and $20 billion. [1][2] In response to the probe, Nvidia stated that the Groq story demonstrates the American system working as designed to promote innovation, reward entrepreneurs, and benefit consumers. [2]

The investigation marks the first time a U.S. regulator has moved from stated concern to an active formal probe of a reverse-acquihire deal structure. [2] The Justice Department is examining whether Nvidia structured the agreement specifically to bypass premerger notification requirements under the Hart-Scott-Rodino Antitrust Improvements Act, which has a notification threshold of $119.5 million. [2] While the agency is reportedly unlikely to seek to unwind the transaction, it could impose financial penalties if it concludes a filing was required. [2] If the arrangement is deemed illegal, the precedent could impact a variety of other deals within the AI industry. [1]

This formal probe tests a legal playbook that has already channeled over $100 billion in capital across the AI sector while bypassing mandatory merger reviews. Nvidia's integration of Groq's inference technology and executive talent reflects a broader industry strategy that initially appeared designed to avoid tripping antitrust wires. If the DOJ successfully penalizes Nvidia under the Hart-Scott-Rodino Act, it will likely chill similar reverse-acquihire maneuvers from other tech giants seeking to absorb AI startups without formal acquisitions.
