US Government Lifts Export Ban on Anthropic's Latest Models After Three-Week Dispute

The Trump administration lifted extraordinary export controls on Anthropic's most advanced models, Mythos 5 and Fable 5, overnight between Tuesday and Wednesday. Commerce Secretary Howard Lutnick announced the decision, ending a dispute lasting nearly three weeks that had cut off access to the models for thousands of users outside the United States and disrupted operations for global corporate clients.

The ban itself caught the industry off guard with its suddenness. On June 12, the White House issued an export directive that immediately cut off all users outside the United States from access to Mythos 5 and Fable 5, Anthropic's newest and most advanced systems. The restriction even applied to the company's own employees working outside the US.

Reason for the Ban

According to a classified cybersecurity assessment, US intelligence agencies determined that the Mythos model could expose vulnerabilities in secure code used by government institutions. To enforce the restriction, authorities relied on decades-old export regulations originally designed for hardware rather than software, a move that itself drew criticism from technology trade lawyers.

Behind the Reversal

The company and its corporate clients had argued from the start that the blockade undermined the competitiveness of American AI providers, since rival models with comparable capabilities faced no such restrictions. Trump's shift in position came after a meeting with Dario Amodei at the G7 summit in France, which was followed by intense lobbying and negotiations between Anthropic's leadership and Secretary Lutnick.

Terms of the Settlement

In exchange for the lifting of restrictions, Anthropic committed to proactively identifying and addressing security risks associated with its models, working closely with the US government on protocols and standards for future versions of Mythos and Fable, and reporting any malicious activity detected around these systems to authorities. The company announced that restoring access began the day after the decision.

What It Means for the Market

The episode illustrates Washington's new strategy toward the global AI market: block access for China and countries deemed threats, while selectively opening foreign markets to American labs that can demonstrate real safeguards. For European and Polish companies using Anthropic's models in the cloud, it's a signal that access to state-of-the-art tools can be restricted at any moment by administrative decision, regardless of the terms of their commercial agreement with the provider.

For Anthropic itself, lifting the ban ends a costly disruption that had hit corporate clients relying on the models for complex data analysis and software development. The company can now resume its full international expansion, though analysts note that the entire episode serves as a warning to the rest of Silicon Valley about how easily regulatory decisions can disrupt global AI business overnight.
