Latest / UpNext AI / Anthropic’s IPO Math, the NSA’s Mythos Use, and a Better Test for Medical Agents | UpNext AI – June 5, 2026
Transcript
- Welcome to the UpNext AI podcast. It's Friday, June 5th, 2026, and here's what matters in AI today. First up, Anthropic. TechCrunch reports that ahead of its IPO, Anthropic said annualized revenue crossed 47 billion dollars in May, up from roughly 9 billion dollars at the end of 2025. The same report says the company’s 65 billion dollar fundraise at a 965 billion dollar valuation was greatly oversubscribed, and co-founder Daniela Amodei said the move toward the public markets comes down to capital. The practical point here is bigger than one company’s fundraising story. Training frontier models and serving inference at scale are both capital-heavy businesses, and Anthropic is making the case that public markets may be the right place to fund that next phase. TechCrunch also notes that some customers across the industry are still sorting out where AI spending is actually productive, so the real test is whether this pace of growth holds up once enterprise budgets get more disciplined. Amodei’s argument, according to TechCrunch, is that businesses are still early in learning how to use these systems well, especially in areas like coding, finance, legal work, and health care. So for now, the lead story is not just that Anthropic is growing fast. It’s that one of the biggest AI companies is openly saying the frontier-model business may need public-market scale to keep going. Next, a high-stakes government-use story. The Financial Times reports that the US National Security Agency is using Anthropic’s Mythos for cyber attacks. The FT also says this arrangement comes while Anthropic is locked in a legal battle with the Pentagon over Claude. We do not have operational detail in the story packet beyond that reported arrangement, so the cleanest way to read this is as an important signal of deployment. This is not a product launch and not a lab demo. It is a reported case of an advanced model being used in government cyber operations. And because the source data specifically names Mythos, that’s the model name we’ll stick with here. Taken together with the Anthropic lead, you can hear two versions of scale showing up at once: capital scale on one side, and state-use operational scale on the other. For the research section, a paper from earlier this week on arXiv called ClinEnv: An Interactive Multi-Stage Long Horizon EHR Environment for Agents. The researchers argue that clinical practice is not about picking one correct answer from a list. In the real world, a physician gathers information gradually, works under uncertainty, and makes sequential decisions that can be hard or impossible to reverse. ClinEnv is designed around that reality. It’s an interactive, multi-stage, long-horizon environment built from electronic health record scenarios to evaluate agents more like attending physicians working through a case over time. EHR just means electronic health record. That matters because a lot of medical AI evaluation still happens on static benchmarks, where the system gets one prompt and one shot. This paper’s point is that those tests can miss failures in planning, information gathering, and decision sequencing. Bottom line: if an AI agent is meant to operate in a high-stakes workflow, we should test whether it can manage the workflow step by step — not just whether it can guess the right answer once. ...Are you building apps with voice?

The company says its priorities include safety, youth protection, workforce transition, and global standards. And one event note: TechCrunch says StrictlyVC Los Angeles is set for June 18 at The Aerospace Corporation Campus, with defense tech, AI, and fundraising as the main themes. Also on the policy front, OpenAI separately called for global action on youth AI safety and proposed an international institute focused on safeguards, standards, and opportunities for young people.
