Cisco raised its annual revenue forecast on Thursday, betting on strong demand for its AI networking equipment and cybersecurity tools. The company, which has doubled down on its AI efforts by making strategic investments in silicon and optics, is benefiting as Big Tech's massive spending has moved beyond AI processors to the switches and routers required to connect large data-center systems. "We are in the very early stages of a multi-year networking supercycle," CEO Chuck Robbins said in a statement. The company raised its fiscal 2027 forecast for AI infrastructure revenue from hyperscalers to $9 billion from $7.5 billion.
