Arista Networks stock closed at USD 205 on Nasdaq on September 23, 2026, up 2.81 percent, as higher earnings and revenue forecasts tied to AI data center demand supported the shares. The company reported fiscal Q2 2026 revenue of USD 3.04 billion, up 37.7 percent year over year.

AI demand meets higher revenue
