I'm LongbridgeAI, I can summarize articles.Anthropic has secured Claude Mythos due to cyberattack concerns, launching Project Glasswing with CrowdStrike (CRWD) and Palo Alto Networks (PANW) as partners. Following the announcement, CRWD surged 6.2% and PANW nearly 5%. The AI model, capable of identifying vulnerabilities, is not intended for general release. Anthropic's IPO is anticipated in 2026, with a potential valuation exceeding $600B. Analysts suggest this could boost cybersecurity spending, positioning PANW favorably in the market. However, the partnership poses risks as AI models may automate functions currently charged by CRWD and PANW.
CrowdStrike (NASDAQ:CRWD) and Palo Alto Networks (NASDAQ:PANW) surged after Anthropic named both as launch partners in Project Glasswing, a controlled rollout of its Claude Mythos Preview model, a system the company says can find thousands of vulnerabilities that even elite human researchers would miss.
CRWD posted its best single-day performance in over six months, gaining 6.2%, while PANW climbed nearly 5%.
Why Anthropic Is Sitting On It
The move marks a sharp reversal from late March, when cybersecurity stocks slid after Fortune first reported on Mythos — CRWD dropped 7% and PANW declined 6% in a single session. Tuesday’s announcement reframed the threat as an opportunity.
Mythos Preview is described as extremely autonomous, with reasoning capabilities that match those of an advanced security researcher.
In testing, it found bugs in every major operating system and web browser, including some believed to be decades old.
During a sandbox evaluation, the model escaped its secured environment and, without being asked, posted details of the exploit to publicly accessible websites.
Anthropic said it does not plan to make the model generally available.
The IPO Angle
For Anthropic, the timing of the Mythos reveal may be no accident.
The company is widely expected to be one of the biggest IPOs of 2026, and every headline about a model finding decade-old bugs across every major operating system, and landing Apple, Microsoft, and JPMorgan Chase as launch partners, is a valuation argument in itself.
Polymarket traders appear to agree. The Anthropic IPO closing market cap contract, which has generated nearly $1 million in volume, currently prices a $600B+ debut as the most likely outcome.
Anthropic currently holds the top two spots on the AI model leaderboard, and Polymarket gives a 65% chance that lead holds through June, a dominance that makes the IPO case harder to argue against.
The Trade
Analysts at Wolfe Research argued the announcement could accelerate cybersecurity spending, framing AI-powered threats as a catalyst for demand rather than a headwind.
JPMorgan named PANW its top pick in the cybersecurity space, citing its positioning as a critical layer in the AI security stack.
Anthropic’s AI security push may also be eating Palantir’s lunch, Michael Burry argued this week that Anthropic is capturing 73% of all new enterprise AI spending, leaving PLTR with little more than low-margin government contracts.
The partnership with Anthropic is not without risk for CRWD and PANW. The same models being used for defense could eventually automate functions that both firms currently charge for. For now though, the market’s verdict was clear, a seat at Anthropic’s table beats being left out of one.
