Claude Mythos 5 Stuck: Anthropic vs. US Export Controls

The timeline of a weekend under pressure

On Friday, June 13, 2026, at 5:21 PM Eastern Standard Time, Anthropic received an export control directive from the U.S. federal government. The document mandated the suspension of access to models Claude Mythos 5 e Fable 5 for any “foreign national,” both within and outside of U.S. territory. Furthermore, the restriction explicitly extended to foreign employees of Anthropic itself.

Therefore, the company was faced with an unavoidable choice: completely disable the newly launched products, or violate a federal directive. Anthropic chose the former. Consequently, within a few hours, they shut down access to the models and sent a delegation to Washington D.C. to negotiate directly with the Trump administration.

As reported by The Verge, all this happened while the United States celebrated its first World Cup victory and the New York Knicks' NBA title. A contrast that makes the scope of the company's institutional crisis even more evident.

The mechanism of export controls applied to AI

American export controls historically originated to regulate the sale of military and dual-use technologies to countries considered adversaries. However, in recent years their application has progressively extended to software and artificial intelligence models. In fact, AI is today considered a strategic technology of primary importance.

In this specific case, the directive did not target a foreign enemy country. On the contrary, it imposed restrictions based on individual nationality, even including workers already present on American soil. This represents a particularly extensive interpretation of the regulations. Therefore, it sets a precedent that could affect any tech company with an international workforce.

According to the analysis of Brookings Institution, The application of export controls to generative AI is still in the regulatory definition phase. Consequently, regulatory uncertainty remains high for all industry players, including European companies using American APIs.

Winners, losers, and those on the fence

The incident has asymmetrical effects on different actors. Anthropic is the most damaged party in the short term: it had to block a product launch on which it had invested weeks of communication and technical preparation. Furthermore, its reputation as a reliable partner for international enterprise clients is weakened.

However, Anthropic's competitors could benefit from this. OpenAI, Google DeepMind, and European players like Mistral AI are watching closely. In fact, any service interruption by a competitor represents an opportunity to acquire customers. Conversely, they are also potentially exposed to similar directives, as they are also American companies with international teams.

However, the most vulnerable parties remain organizations that had already integrated Claude Mythos 5 into their workflows. Among these are many European SMEs that had adopted Anthropic's APIs to automate internal processes, particularly those that had not planned any business continuity measures in case of service interruption.

A Milanese agency's perspective on the Italian AI ecosystem

We of SHM Studio We are closely following the regulatory evolution of artificial intelligence, both European and American. This episode confirms a thesis we have long supported: relying on a single AI model, no matter how powerful, is a strategically risky choice.

Italian SMEs that today use American AI models for activities such copywriting, digital marketing o process automation They must start thinking in terms of vendor diversification. Furthermore, it is necessary to carefully evaluate the contractual terms of AI providers, verifying who holds responsibility in case of service interruption.

Therefore, the question is no longer just “which AI model is more performant,” but also “which AI model guarantees operational continuity in adverse geopolitical scenarios.” This is a dimension of analysis that Italian companies still struggle to adopt systematically.

Implications for European Business Compliance

From a regulatory standpoint, the Anthropic affair fits into an already complex landscape.’EU AI Act, which came into effect in 2024 and will be progressively applied throughout 2025, imposes increasing obligations on providers and users of high-risk AI systems. Therefore, Italian SMEs find themselves navigating between two distinct regulatory systems: the European one and the American one.

According to Gartner, By 2027, more than 60% of European organizations will need to review their contracts with AI suppliers to ensure compliance with the EU AI Act. In this scenario, the addition of variables related to U.S. export controls further increases the complexity of corporate AI governance.

Furthermore, the directive received from Anthropic raises questions about the extraterritorial reach of US laws. Indeed, if a US company can be forced to block access to its services even for European users, then European digital sovereignty becomes a concrete issue, not just a theoretical one.

Next moves: what Italian SMEs should do

The first concrete action is to conduct a AI dependency auditMap all business processes that depend on external AI models, identifying single points of failure. This exercise is often overlooked but is essential for assessing operational risk exposure.

Subsequently, it is appropriate to evaluate European or open-source alternatives for the most critical functions. Models like Mistral, also available in a self-hosted version, offer greater control over service continuity. Similarly, on-premise solutions reduce exposure to foreign regulatory directives.

Finally, contracts with AI providers need to be updated, including specific clauses on SLAs, liability in case of downtime, and data portability. The activities of web development, SEO e Google Ads campaigns that integrate AI must be designed with resilient architectures. Similarly, strategies of LinkedIn campaign AI-generated content requires an operational Plan B.
