Arista Raises 2026 AI Revenue Target to $3.25 Billion

Overview

• Arista lifted its 2026 AI revenue goal to $3.25 billion from $2.75 billion, pointing to faster uptake of its Ethernet switches and EOS software in AI clusters.
• Analysts at Evercore ISI and Piper Sandler say Arista is gaining on InfiniBand in high-speed data center networking that links thousands of AI training servers.
• Recent results underscore strong execution, with FY2025 revenue above $9 billion and Q4 net income topping $1 billion on unusually high margins.
• Microsoft and Meta made up about 42% of revenue in late 2025, which concentrates risk in a small set of cloud buyers.
• Rosenblatt upgraded the stock earlier this month after new work with Google and Anthropic, suggesting Arista is widening its customer base beyond its top two accounts.
