The US Justice Department is investigating Nvidia's acquisition of Israeli AI startup Run:ai, suspecting that it may violate antitrust laws. In April of this year, Nvidia announced the acquisition but did not disclose the price, which is estimated to be around $700 million. The Justice Department has inquired about the transaction's competitive impacts from market participants, but the scope of the investigation is unclear. Nvidia stated that it complies with the law, supports industry innovation, and is willing to provide any necessary information. Run:ai has not responded to requests for comment. US regulators are ramping up scrutiny of anticompetitive behavior in the AI sector, particularly concerning large tech companies.
