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) surged 6.2% while Palo Alto (PANW) climbed 4.9% during Tuesday’s session, with each stock gaining an additional 2% after hours
- Despite the rally, PANW remains down 7.8% and CRWD has declined 9.7% year-to-date in 2026
- The AI company plans to allocate up to $100 million in usage credits along with $4 million for open-source security initiatives
- This announcement follows March’s selloff in cybersecurity names when Anthropic first disclosed Mythos, sparking concerns about AI displacing conventional security solutions
Cybersecurity investors found reason for optimism Tuesday as Anthropic’s Project Glasswing announcement sparked a rally in major security stocks. Palo Alto Networks and CrowdStrike both recorded substantial gains following news that the AI firm would grant access to its yet-to-be-released Mythos Preview model for defensive security applications.
The collaboration brings together an impressive roster of technology leaders — Amazon Web Services, Apple, Broadcom, Cisco, Google, JPMorgan Chase, the Linux Foundation, Microsoft, and Nvidia are all participating alongside PANW and CRWD.
According to Anthropic, Mythos Preview represents an AI model that can outperform “all but the most skilled humans” in identifying and exploiting security weaknesses in software. The company positions the initiative as a critical effort to channel these advanced capabilities toward protection rather than attack.
The timing marks a significant reversal from recent market sentiment. Just two weeks earlier, on March 27, when Fortune broke news about Anthropic’s Mythos model development, cybersecurity stocks tumbled. Market participants worried that increasingly sophisticated AI tools might erode the need for established security platforms.
Tuesday’s news offered a contrasting narrative — at least temporarily.
Palo Alto Networks, Inc., PANW
PANW advanced nearly 5% during regular trading, while CRWD jumped 6.2%. Extended trading brought another 2% increase for both names. The momentum carried into Wednesday’s premarket hours.
However, the year-to-date context remains challenging. Palo Alto Networks has shed 7.8% since January, while CrowdStrike is down 9.7% in 2026. Tuesday’s surge helps narrow those deficits but doesn’t eliminate them.
Anthropic’s Financial Commitment
Anthropic has pledged up to $100 million in AI usage credits for Project Glasswing participants. Additionally, the company will direct $4 million toward open-source security projects.
These substantial commitments suggest Anthropic aims to establish a genuine defensive security framework rather than merely issuing a symbolic partnership announcement.
The Strategic Dilemma
For both PANW and CRWD, this development presents opportunities alongside potential risks. The positive angle: it confirms AI-enhanced security as a legitimate growth sector — an area where both companies have already established strong footing.
The flip side: these same advanced AI systems being deployed defensively could eventually automate capabilities that cybersecurity vendors currently monetize. Should AI reach a point where it independently identifies and neutralizes threats, demand for certain traditional security products might diminish.
This fundamental tension persists. Yet for Tuesday and Wednesday’s trading, investor sentiment was unambiguous: securing a seat at Anthropic’s table was preferable to being excluded.
Both cybersecurity names maintained upward momentum in Wednesday’s premarket trading following Tuesday’s close.
