What Happened?
Shares of cloud security platform Zscaler (NASDAQ: ZS) jumped 4.1% in the afternoon session after cybersecurity stocks rebounded as analysts projected potential gains from the adoption of AI models.
The momentum was catalyzed by a KeyBanc survey of CIOs, which revealed a positive impact on cyber budgets within the next year due to Anthropic's Mythos AI model. Leading cybersecurity platforms are expected to benefit from the projected growth as enterprises expand their security budgets to stay ahead of the latest threats.
After the initial pop the shares cooled down to $139.72, up 3.7% from previous close.

What Is The Market Telling Us
Zscaler’s shares are quite volatile and have had 17 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The previous big move we wrote about was 6 days ago when the stock gained 6.5% on the news that markets benefited from a "risk-on" sentiment fueled by potential peace negotiations between the U.S. and Iran.
As geopolitical tensions eased, investors returned to growth-heavy favorites like Microsoft and ServiceNow, which offer high-margin subscription revenue and clearer paths for integrating generative AI into enterprise workflows.
Zscaler is down 36.6% since the beginning of the year, and at $139.72 per share, it is trading 58.4% below its 52-week high of $336.27 from November 2025. Investors who bought $1,000 worth of Zscaler’s shares 5 years ago would now be looking at only $751.02.
