Palo Alto Networks (PANW) and CrowdStrike (CRWD) stocks rose sharply after Anthropic announced they would be partners in its new Project Glasswing, which aims to leverage Anthropic's powerful Mythos Preview AI model for defensive cybersecurity purposes. Anthropic is committing up to $100 million in AI usage credits and $4 million toward open-source security projects as part of the initiative, which also includes major tech firms like Amazon, Apple, and Microsoft.

Why it matters

The partnership is seen as a validation of AI-powered security as a growth area, where PANW and CRWD are already well-positioned. However, the same powerful AI models being used for defense could also automate some traditional security functions over time, raising questions about the long-term impact on cybersecurity firms.

The details

Anthropic launched Project Glasswing, partnering with major tech and cybersecurity firms to use its unreleased Mythos Preview AI model for defensive security. PANW stock rose 4.9% and CRWD popped 6.2% on Tuesday, with both adding another 2% in after-hours trading. Anthropic will commit up to $100 million in usage credits and $4 million toward open-source security projects as part of the initiative.
