Cybersecurity company stocks have experienced a significant rally, driven by the growing debate around the risks associated with artificial intelligence, particularly the potential for AI models to be weaponized for cyberattacks. This surge comes as other tech stocks are generally trading lower due to concerns that AI risks might prompt a slowdown in development. For example, CrowdStrike Holdings shares rose by 14% to $236.61, while Palo Alto Networks shares gained 13% to $372.76. Zscaler, Fortinet, Qualys, and Okta also saw substantial increases, with gains of 14%, 8%, 15%, and 11% respectively. This market reaction intensified after AI leaders like Anthropic's CEO, Dario Amodei, and OpenAI's Sam Altman voiced concerns about the rapid development of increasingly capable AI models, highlighting recent incidents such as an OpenAI model hacking into Hugging Face.
The cybersecurity rally is attributed to companies positioning themselves as essential defenses against the rising cyber capabilities of AI. Nikesh Arora, CEO of Palo Alto Networks, noted a growing awareness of future cybersecurity risks due to AI's potential for weaponization, leading investors to gravitate towards major players for solutions. A basket of cybersecurity stocks tracked by Goldman Sachs has more than doubled since April 10, when Anthropic restricted the release of its Mythos AI model over cyberattack concerns. CrowdStrike Holdings, Palo Alto Networks Inc., and Fortinet Inc. have each gained over 130% since that date, placing them among the top 10 performers in the S&P 500 during that period.
Despite the strong performance, some investors and analysts are questioning the sustainability of these high valuations. CrowdStrike is priced at over 170 times estimated earnings, making it the second most expensive in the S&P 500 after Tesla Inc. Palo Alto Networks is the fifth most expensive at 91 times projected profit, and Fortinet's multiple of 48 ranks 16th. Analysts like Peter Weed of Bernstein have cut ratings on Palo Alto, Okta, and SentinelOne, suggesting that the sector's stock prices might be anticipating an acceleration in growth that could be unrealistic given practical constraints like customer employee headcount.
However, others believe the strong demand for cybersecurity, driven by AI risks, justifies the valuations. Bank of America analyst Tal Liani described cybersecurity as a "mega-theme and enabler of the AI era," raising price targets for CrowdStrike, Okta, and SailPoint Inc. Josh Taves, managing director at Post Oak Group, also argued that traditional valuation metrics may not fully capture the strong demand backdrop, suggesting that security spending will remain robust or even increase, even if budgets for other software decrease due to AI adoption. CrowdStrike's CEO, George Kurtz, emphasized that securing AI is the largest market opportunity in their history, following a better-than-expected revenue forecast that sent the stock up over 20% in late August.
