Anthropic has just eclipsed OpenAI in valuation, closing a staggering $65 billion Series H funding round that values the AI startup at $965 billion. The massive influx of capital arrives precisely as the company releases Claude Opus 4.8, a new flagship model boasting improved coding capabilities and a novel “Dynamic Workflows” tool for coordinating swarms of AI subagents.
Anthropic achieved a massive breakthrough with its new “Mythos” AI model, but the system proved so adept at exploiting zero-day vulnerabilities that the company entirely scrapped a public release. Instead, Anthropic is carefully rationing access to tech giants and government agencies to preemptively patch critical flaws, sparking intense geopolitical maneuvering and driving the startup’s valuation past $800 billion.
The intersection of artificial intelligence and national hard power dominated this week as the US government aggressively bypassed its own guardrails to integrate commercial AI into classified military networks. While the Pentagon signed sweeping, consequence-free deals with tech giants like Google and OpenAI, it notably blacklisted Anthropic over supply-chain disputes, even as the NSA secretly utilized Anthropic’s “Mythos” model for cybersecurity. This fractured, frantic procurement strategy highlights a decisive shift: Silicon Valley has largely abandoned its hesitancy regarding military applications, cementing a lucrative, hyper-militarized future for frontier AI development.
An AI system powered by Anthropic’s Claude Sonnet 4.6, named “Luna,” was given a $100,000 budget and a corporate card to successfully open and operate a physical retail boutique in San Francisco. The autonomous agent handled everything from hiring painters on Yelp to ordering inventory and setting up the store’s internet service, marking a bizarre and massive new frontier for AI capabilities in the physical world.
The US government is actively seeking access to Anthropic’s highly sophisticated ‘Mythos’ AI model to bolster its cybersecurity defenses, reflecting a frantic geopolitical race to harness AI for national security. Despite Anthropic currently battling the Trump administration in court, top officials recognize that ignoring the AI’s ability to autonomously identify and exploit zero-day vulnerabilities would be a massive strategic misstep.
