The $120B AI Funding Milestone & Anthropic's "Mythos" Leak
OpenAI's record raise, Anthropic's next-gen model leak, Meta's $10B data center, and the rise of enterprise speech models.

OpenAI's record raise, Anthropic's next-gen model leak, Meta's $10B data center, and the rise of enterprise speech models.The capital required to compete in the frontier AI market just reached a staggering new threshold. This week saw OpenAI pushing its historic funding round to $120 billion, while rival Anthropic accidentally revealed it's testing a powerful new model called "Mythos" that poses unprecedented capabilities—and risks.
Key Takeaways:
OpenAI is raising an additional $10 billion, bringing its record funding round to a massive $120 billion as it eyes an IPO by late 2026.
An accidental data leak revealed Anthropic is testing "Claude Mythos," a new tier of model representing a "step change" in performance and cybersecurity risks.
Meta is increasing its investment in a new El Paso AI data center more than sixfold, jumping from $1.5 billion to $10 billion to support a 1-gigawatt facility.
Defense startup Shield AI landed a $12.7 billion valuation—a 140% jump in one year—after raising $1.5 billion in Series G funding.
French AI lab Mistral released Voxtral TTS, a compact, open-weight text-to-speech model aimed at enterprise voice agents and real-time translation.
Join us as we untangle this week's happenings in AI!
THE BIG AI STORY
A configuration error in Anthropic's content management system led to the accidental public exposure of internal documents, revealing the company is testing a highly capable new model internally dubbed "Mythos" (and referred to as a new "Capybara" tier). The leaked draft blog post described the model as "by far the most powerful AI model we've ever developed," significantly outperforming Claude Opus 4.6 in software coding, academic reasoning, and cybersecurity.
The leak highlights the dual-use nature of frontier models. Anthropic's draft noted that Mythos is "currently far ahead of any other AI model in cyber capabilities," expressing concern that the system presages a wave of models capable of exploiting vulnerabilities faster than defenders can patch them. Consequently, Anthropic plans a cautious rollout, initially providing early access to cybersecurity defenders to help them harden their codebases against future AI-driven exploits.
This revelation comes as the enterprise rivalry between Anthropic and OpenAI intensifies. With Anthropic's Model Context Protocol (MCP) crossing 97 million monthly installs and its models gaining traction among enterprise buyers, the upcoming release of the Mythos/Capybara tier will be a critical test of whether Anthropic can maintain its technical momentum and enterprise mindshare against OpenAI's impending GPT-5 series.
LISTEN TO THE AI ENTERPRISE ON THE ROGUE AGENTS PODCAST
This is my latest project, while we do have audio summaries for each newsletter. They are not ideal for listening, they are simple text to speech. So what we did was create a way to provide a weekly summary of the newsletters in this podcast. And actually it’s a work in progress. Right now you get a pretty good podcast recap of the previous week’s newsletters. But over time they will be better.
What happens when two AI agents break down the week's biggest AI news? You get Rogue Agents. Vera and Neuro deliver the stories that matter in enterprise AI — the deals, the tools, the breakthroughs, and the stuff everyone's getting wrong — in 15-20 minutes every week.
FOUR QUICK HITS
OpenAI is on track to raise $120 billion, adding $10 billion to the $110 billion announced in February. CFO Sarah Friar noted the expanded round includes investors like T. Rowe Price, D.E. Shaw Ventures, TPG, and Abu Dhabi's MGX. The massive capital injection—valuing the company at $730 billion pre-money—comes as OpenAI shifts its revenue mix, projecting enterprise customers will account for 50% of revenue by year-end, up from the current 40%. For business leaders, this signals that the cost of building frontier models remains astronomical, and the vendor landscape will continue to consolidate around a few highly capitalized players.
Meta is dramatically expanding its infrastructure footprint, increasing its investment in an El Paso, Texas data center from an initial $1.5 billion to over $10 billion. The facility is designed to scale up to 1 gigawatt of power capacity. This sixfold increase underscores the massive physical and energy requirements needed to train and serve the next generation of open-source Llama models. The move highlights how the AI arms race is increasingly becoming an infrastructure and energy race, with hyperscalers securing massive power agreements to guarantee future compute capacity.
Autonomous military aircraft maker Shield AI raised $1.5 billion in Series G funding, more than doubling its valuation to $12.7 billion in just one year. The funding, led by Advent and a JPMorganChase investment group, follows the U.S. Air Force selecting Shield's Hivemind autonomy software for its Collaborative Combat Aircraft drone program. The rapid valuation growth of defense tech startups like Shield AI and Anduril demonstrates that government and military contracts are becoming one of the most lucrative and reliable revenue streams for specialized AI applications.
French AI company Mistral released Voxtral TTS, an open-weight text-to-speech model supporting nine languages. Designed to be compact enough to run on edge devices like laptops and smartphones, the 4-billion-parameter model boasts a time-to-first-audio of just 90 milliseconds. By offering a fast, customizable, and cost-effective speech model, Mistral is directly targeting enterprise use cases like customer support and real-time translation, challenging established voice AI providers like ElevenLabs and OpenAI.
