Anthropic announcements have been a problem for software and cybersecurity stocks, but that narrative was changing for Palo Alto Networks and CrowdStrike Holdings on Tuesday.
Anthropic announced a partnership called Project Glasswing with a collection of companies, including Amazon Web Services, Apple, Broadcom, Cisco Systems, Alphabet's Google, JPMorgan Chase, the Linux Foundation, Microsoft, Nvidia, CrowdStrike, and Palo Alto.
The listed companies will be able to use Mythos Preview -- an unreleased artificial intelligence model -- as part of their "defensive security work," according to a blog post by Anthropic.
"AI models have reached a level of coding capability where they can surpass all but the most skilled humans at finding and exploiting software vulnerabilities," Anthropic said. The AI start-up added that Project Glasswing is "an urgent attempt to put these capabilities to work for defensive purposes."
Palo Alto stock jumped 4.9% and CrowdStrike stock popped 6.2% on Tuesday following the announcement.
Those are notable moves for the cybersecurity firms, which have seen their stocks drop 7.8% and 9.7%, respectively, this year. Some on Wall Street are worried that software capabilities will be replaced by improved models released by companies like Anthropic and OpenAI.
Those concerns specifically hit the cybersecurity space on March 27 after Fortune reported that Anthropic was developing the new Claude large-language model Mythos. Questions swirled about whether or not cybersecurity firms could keep up with the complexities that AI introduces when it comes to keeping systems protected.
A partnership with Anthropic looks to be alleviating those fears.
