Palo Alto Networks (PANW) and CrowdStrike (CRWD) Surge on Anthropic’s AI Security Partnership

Key Takeaways

• Anthropic unveiled Project Glasswing, collaborating with leading technology and cybersecurity companies to deploy its upcoming Mythos Preview AI model for security defense purposes
• CrowdStrike (CRWD) shares surged 6.2% while Palo Alto Networks (PANW) climbed 4.9% during Tuesday’s session, with both adding approximately 2% in extended trading
• Despite Tuesday’s rally, PANW remains down 7.8% year-to-date while CRWD has declined 9.7% in 2026
• The AI company plans to allocate up to $100 million in platform usage credits and dedicate $4 million to open-source cybersecurity initiatives
• This announcement follows a sharp selloff in cybersecurity equities last month when Anthropic first disclosed Mythos, sparking concerns about AI disruption in the security sector

Cybersecurity investors found reason for optimism Tuesday as Anthropic’s Project Glasswing announcement sent shares of both Palo Alto Networks and CrowdStrike significantly higher. The artificial intelligence firm revealed plans to provide access to its forthcoming Mythos Preview model specifically for defensive cybersecurity applications.

The collaboration brings together technology industry heavyweights — Amazon Web Services, Apple, Broadcom, Cisco, Google, JPMorgan Chase, the Linux Foundation, Microsoft, and Nvidia all join PANW and CRWD as participating partners.

According to Anthropic, Mythos Preview represents an AI system that can match or exceed the abilities of highly skilled security professionals when identifying and exploiting vulnerabilities in software systems. The company positions the initiative as a critical effort to ensure these capabilities strengthen defenses rather than enable attacks.

The timing marks a dramatic reversal from recent sentiment. When Fortune broke news on March 27 about Anthropic’s Mythos model development, cybersecurity stocks tumbled as investors worried that advanced AI might erode the need for conventional security solutions.

Tuesday’s partnership reveal seemingly reversed that narrative — at least temporarily.

Palo Alto Networks, Inc., PANW

Palo Alto Networks posted gains approaching 5%, while CrowdStrike advanced 6.2% during regular trading hours. After-hours activity added roughly 2% to both positions. The momentum carried into Wednesday’s pre-market session.

However, the year-to-date performance remains challenging. PANW has surrendered 7.8% since January, and CRWD sits 9.7% lower through 2026. Tuesday’s advance provides some relief but leaves substantial losses intact.

Anthropic’s Financial Commitment

Anthropic has pledged up to $100 million worth of AI platform credits for Project Glasswing participants. Additionally, the company earmarked $4 million for open-source security development efforts.

These substantial allocations suggest Anthropic intends to build a genuine defensive security framework rather than merely announcing a symbolic collaboration.

A Complex Calculation for Security Firms

For both Palo Alto Networks and CrowdStrike, Project Glasswing presents opportunities alongside potential challenges. The initiative confirms AI-enhanced security as an expanding market segment — an area where both companies have established footholds.

Conversely, the same sophisticated AI capabilities being harnessed for protection could eventually automate services that cybersecurity vendors currently monetize. Should AI systems become capable of independently identifying and mitigating threats, demand for certain traditional security products might contract.

This fundamental question remains unresolved. Yet Tuesday and Wednesday’s market response delivered a clear verdict: securing a seat at Anthropic’s table outweighs the alternative.

Both PANW and CRWD sustained their upward momentum in pre-market trading Wednesday morning following Tuesday’s strong close.
