Arista Networks builds high-performance Ethernet switches and software platforms that power the backbone infrastructure of cloud data centers and enterprise networks. The company dominates the 100 gigabit and 400 gigabit switching market where hyperscale cloud providers like Microsoft and Meta require ultra-low latency and massive bandwidth capacity. AI workload deployment is driving explosive demand for Arista's cognitive campus solutions and data center interconnects as companies race to build GPU clusters that can handle training and inference at scale. Revenue jumped 47% year-over-year in Q3 to $1.81 billion, with the AI campus segment alone growing 300% as enterprises retrofit their networks for machine learning applications. Trading at 41x forward earnings, the stock has run hard but the AI infrastructure buildout is still in early innings.
