Using an unordered list, summarize the following article with between 4 and 8 key points.
\n Anthropic has put its most advanced AI model on the table for the European Union, but getting a seat at that table is proving to be a slow, grinding negotiation. The company\u2019s Mythos model, capable of autonomously discovering zero-day vulnerabilities across every major operating system and web browser, remains accessible to only about 40 vetted US companies and select government entities. The EU wants in. Anthropic hasn\u2019t said no. But progress, according to Spain\u2019s economy minister, has been \u201climited.\u201d
\nWhat Mythos actually does
\nAnthropic announced the Claude Mythos Preview on April 7, 2026. In internal testing, the model discovered thousands of zero-day vulnerabilities, the kind of software flaws that vendors don\u2019t know about and therefore can\u2019t patch, across all major operating systems and web browsers.
\nMythos doesn\u2019t just flag vulnerabilities. It autonomously generates working exploits, meaning it can demonstrate exactly how an attacker would use each flaw. On industry benchmarks like Cybench, the model surpasses every prior AI system at conducting complex, multi-step cyber-attack simulations.<\/p>\n

That dual capability, defense and offense in a single package, is precisely why Anthropic chose to restrict access. The company launched Project Glasswing to manage distribution, limiting the model to roughly 40 vetted US companies and chosen government entities.
\nThe EU negotiation
\nEuropean officials have been trying to secure access to Mythos for their own cybersecurity apparatus. As of May 22, 2026, Spain\u2019s economy minister characterized the progress in EU-Anthropic negotiations as \u201climited.\u201d
\nThe European Commission planned to send officials to San Francisco in late May 2026 to press for more details on the model and explore terms for access. Meanwhile, OpenAI provided the EU access to its own cyber-focused model, GPT-5.5-Cyber. The UK\u2019s AI Safety Institute has been evaluating Mythos separately, suggesting that Britain\u2019s post-Brexit positioning may be giving it a faster track to access than the broader EU bloc.
\nWhat this means for investors
\nCrypto exchanges, custodians, and DeFi protocols are among the most targeted digital infrastructure in the world. The roughly 40 US companies in the Project Glasswing cohort are essentially receiving a head start in AI-augmented cybersecurity. European competitors without equivalent access face a structural disadvantage that could persist for months or longer, depending on how negotiations unfold.
\nThe EU has historically been more aggressive than the US in regulating AI through frameworks like the AI Act, with enforcement set for August 2026. The irony of Europe now needing to negotiate for access to American AI capabilities, while simultaneously trying to regulate how those capabilities are deployed, creates a genuine policy tension.
\nThe OpenAI-EU arrangement with GPT-5.5-Cyber also signals that competition for institutional AI partnerships is intensifying. Investors should watch whether Anthropic\u2019s restrictive approach ultimately strengthens its brand as the \u201cresponsible\u201d AI company, or whether it simply cedes market share to rivals willing to distribute more broadly.<\/p>\n
