Shares of Arista Networks (ANET) soared 8.2% on March 4, 2026, one day after company executives presented an expanded market opportunity outlook at the Morgan Stanley Technology, Media & Telecom Conference.
The networking equipment manufacturer’s shares ended trading at $134.83 after the March 3 investor presentation.
The catalyst driving the stock’s impressive gain was Arista’s TAM update. The company increased its Total Addressable Market projection to $105 billion from a previous estimate of $60 billion. This represents an almost 75% expansion of the company’s identified growth potential.
Executives also stood by their earlier projection of $3.25 billion in AI networking revenue for 2026. This segment is anticipated to account for approximately 30% of the company’s overall revenue.
Total annual revenue is on track to exceed $10 billion, marking an increase from last year’s $9 billion. Additionally, management indicated that as many as four individual customers might each represent more than 10% of total revenue during the current year.
Beyond financial projections, the conference presentation detailed Arista’s technological approach to AI networking infrastructure. The company showcased its all-Ethernet AI spine and leaf architecture. At the heart of this system is the 7800 AI Spine product, which delivers 800-gigabit performance and enables large-scale deployment strategies.
Arista is collaborating with data center operators on three distinct infrastructure approaches: scale-up, scale-out, and scale-across configurations.
Wall Street’s Take
The stock’s upward movement came after Piper Sandler increased its price objective on February 13. The investment firm lifted its target from $159 to $175 while reiterating its Overweight stance following Arista’s strong quarterly performance.
Quarterly revenue reached $2.49 billion, surpassing the Wall Street consensus of $2.38 billion. Earnings per share of $0.82 exceeded analyst projections of $0.76.
Piper Sandler also highlighted Arista’s updated annual growth target of 25%, representing a five-percentage-point increase from its previous guidance.
Supply Chain Considerations
During the conference, Arista identified a persistent challenge: memory supply constraints impacting its customer base. Company leadership estimates this bottleneck will take approximately two years to resolve, noting that Arista is making strategic investments in chips, silicon, and memory components to mitigate the impact.
This supply limitation warrants attention, especially given the accelerating customer demand for AI-focused infrastructure solutions.
From a technical perspective, ANET is currently positioned above both its 50-day and 200-day moving averages. The immediate resistance level stands at $137.15. With a 52-week low of $59.43, the current trading price sits approximately 127% higher than that bottom.
The stock continues to trade roughly 18% beneath its 52-week peak of $164.94.
Piper Sandler’s $175 price target suggests approximately 30% potential upside from the March 4 closing price.
