Zscaler is trading 6.37% up at $179.23 as fresh warnings from leading AI companies raised AI-safety concerns, increasing perceived demand for security software.
- The move comes despite broader U.S. market weakness; major peers also gained in premarket trading.
- No fresh company-specific announcement was identified on September 14, 2026.
- September 3 earnings beat and fiscal 2027 guidance remain the latest major company catalysts, but do not directly explain today’s rally; the move appears sector-driven.
