- Arista shares jumped 8.2% Wednesday, then picked up another 1% or so in early pre-market action Thursday.
- Arista CEO Jayshree Ullal, speaking at a Morgan Stanley conference, said the company is on track to top $10 billion in revenue this year. She pegged Arista’s market opportunity at $105 billion.
- Executives flagged that memory-chip shortages might persist, and described Nvidia as a partner—but also a competitor—when it comes to AI networking.
Arista Networks jumped 8.2% Wednesday, finishing at $134.83. Shares added another 1% in early pre-market moves Thursday. The networking equipment company, based in Santa Clara, California, is now valued around $183 billion.
Arista is back under the microscope as investors look for the next round of AI data center spending. Switches and routers—crucial infrastructure—can become choke points; when they falter, big AI clusters lose momentum.
Arista targets big cloud operators and AI-driven data center builders, offering Ethernet switches and network software. Competition is picking up: Cisco remains a dominant force, and Nvidia has started moving further into Ethernet networking, adding to its AI chip portfolio.
Speaking at the Morgan Stanley technology conference on Tuesday, Arista CEO Jayshree Ullal said the firm’s total addressable market has jumped—now estimated at $105 billion, up from $60 billion. Ullal also told attendees Arista expects to “cross the $10 billion mark this year,” following last year’s roughly $9 billion in revenue. She pointed to the possible addition of one or two new customers, each potentially making up about 10% of revenue. Investing.com UK
Ullal called Nvidia both a collaborator on accelerators and a rival, citing its Mellanox networking arm and bundled offerings like Spectrum‑X, designed to more tightly connect Ethernet networks to GPUs. She highlighted Arista’s 7800 “AI Spine” switch, capable of 800 gigabits per second, and said Arista plans to move to co-packaged optics — integrating optical components directly into switches — when open standards materialize. However, she cautioned that memory chip shortages for servers are squeezing customers and could linger up to two years. President and CTO Ken Duda weighed in, asserting that “open and interoperable wins” as the next phase of hardware emerges. Investing
Arista reported fourth-quarter revenue of $2.488 billion and closed out 2025 with a full-year top line of $9.006 billion, according to a February statement. CEO Jayshree Ullal called it “revenue of $9 billion.” CFO Chantelle Breithaupt pointed out the company logged “surpassing $1 billion in quarterly net income” for the period. For the first quarter, Arista is guiding to revenue around $2.6 billion. Arista Networks
The rally doesn’t leave much cushion if cloud spending slows or if customers pivot faster toward in-house networking setups tailored for AI chips. Just last month, Arista projected yearly revenue would top analyst expectations, riding a surge in data-center activity. Still, that appetite isn’t constant—waves come and go. Rivals can step up, pressuring prices.
Director Charles Giancarlo offloaded 8,000 Arista shares on March 2, according to a Wednesday filing. The sale, done via a pre-set Rule 10b5-1 trading plan, saw shares go for roughly $127 to $130 apiece. The stock was held in a family trust, the filing noted.
Investors want to see whether Arista’s widening client list is enough to balance out volatility from its biggest customers, especially as supply issues hopefully loosen instead of getting worse. The stock’s action at this point? The market continues to value straightforward AI networking plays.
