Amazon CEO Andy Jassy reportedly raised security concerns about Anthropic’s AI models with U.S. government officials, a disclosure that preceded a government-imposed export control ban on two Anthropic models in June 2026.
According to The Wall Street Journal, Jassy told Treasury Secretary Scott Bessent and other government officials that Amazon researchers had used Anthropic’s Claude Fable 5 model to obtain information that could be used in cyberattacks. Following those discussions, the government imposed an export control ban on both the Fable 5 and Mythos 5 models, cutting off worldwide access to the two products.
An Amazon spokesperson confirmed to the WSJ that the company does engage with governments on security matters, but said it does not “share the details of those discussions.” The Information and Reuters also reported that Amazon — a major investor in Anthropic — had communicated concerns about the security of Anthropic’s models.
David Sacks, Trump’s former AI czar who now co-chairs the President’s Council of Advisors on Science and Technology, offered a separate account of events. Sacks said “a highly credible trusted partner of both Anthropic and the USG” came forward with information about a jailbreak. He added that the administration asked Anthropic CEO Dario Amodei to fix the jailbreak or take the model offline, and that Amodei refused.
The episode highlights the intersection of private AI investment and government security oversight, with one of Anthropic’s biggest financial backers appearing to have played a direct role in triggering federal action against the company’s own models. Anthropic has not publicly disputed the sequence of events described by Sacks or the WSJ’s reporting.
