Key Takeaways
- Anthropic unveiled Project Glasswing, teaming up with leading technology and cybersecurity companies to deploy its upcoming Mythos Preview AI model for protective security measures
- Palo Alto Networks (PANW) climbed 4.9% while CrowdStrike (CRWD) surged 6.2% during Tuesday’s session, with each stock adding another 2% in extended trading
- Year-to-date performance shows PANW down 7.8% and CRWD down 9.7% in 2026
- Anthropic plans to allocate up to $100 million in usage credits plus $4 million for open-source security initiatives through this program
- The announcement follows a difficult period for cybersecurity stocks in March when Anthropic first disclosed Mythos, sparking concerns about AI displacing conventional security solutions
Tuesday brought welcome news for cybersecurity shareholders as Anthropic’s Project Glasswing announcement drove significant gains in both Palo Alto Networks and CrowdStrike. The AI company revealed plans to grant access to its forthcoming Mythos Preview model specifically for defensive security applications.
The collaboration features an impressive roster of technology leaders — Amazon Web Services, Apple, Broadcom, Cisco, Google, JPMorgan Chase, the Linux Foundation, Microsoft, and Nvidia have all joined forces with PANW and CRWD in this initiative.
Anthropic characterized Mythos Preview as an AI system that performs at levels exceeding “all but the most skilled humans” when identifying and exploiting software weaknesses. The company presented the initiative as a critical effort to channel these capabilities toward protection rather than attack.
The contrast with recent events is striking. Fortune’s March 27 report about Anthropic developing the Mythos model triggered sharp declines in cybersecurity stocks. Market participants worried that advanced AI technology could erode demand for established security platforms.
Tuesday’s news reversed that sentiment — temporarily, at least.
Palo Alto Networks, Inc., PANW
CRWD posted a 6.2% gain during regular trading, while PANW advanced nearly 5%. Extended trading brought an additional 2% increase for both securities. Early Wednesday momentum has carried these gains into premarket activity.
The year-to-date perspective remains challenging, though. PANW carries a 7.8% decline since January, while CRWD has fallen 9.7% during 2026. Tuesday’s rally narrows these losses without eliminating them.
Anthropic’s Financial Commitment
Anthropic has pledged up to $100 million in AI usage credits for Project Glasswing participants. The company will also direct $4 million toward open-source security projects.
These substantial financial commitments suggest Anthropic intends to develop a functional defensive security framework rather than merely announcing a symbolic partnership.
The Dual Nature of This Development
For PANW and CRWD, this project presents both opportunities and challenges. The initiative confirms AI-driven security as an expanding market segment — an area where both companies have already established strong positions.
Conversely, the same advanced AI models deployed for protection could eventually automate capabilities that cybersecurity companies currently monetize. Should AI systems independently detect and eliminate threats, demand for certain traditional security products might diminish.
This fundamental question remains unresolved. However, Tuesday and Wednesday’s market response delivered a clear message: participating in an Anthropic partnership outweighs being excluded from one.
Both securities maintained their upward trajectory during Wednesday’s premarket trading following Tuesday’s closing bell.
