While investors chase the most obvious winners in artificial intelligence (AI), some of the most powerful opportunities are being quietly built behind the scenes. As the AI boom moves from hype to infrastructure, an overlooked player, Arista Networks (ANET), is emerging at the center of massive data flows, cloud expansion and next-generation networks, positioning it to offer enormous advantages as AI grows.

While much of the attention in the AI space has been focused on chips and models, the companies that enable AI development are equally vital. Arista Networks creates networks that transfer massive volumes of data quickly, securely, and efficiently between servers, GPUs, and storage, which is essential for AI training, inference, and cloud computing.
The importance of Arista’s business model led to the generation of nearly $2.31 billion in revenue in the third quarter, an increase of 27.5% year over year (YoY), driven by strong demand among cloud, AI, enterprise and campus customers. Software and services accounted for 18.7% of revenue, highlighting the growing relevance of Arista’s higher-margin solutions. Adjusted gross margin increased to 65.2%, driven by positive product mix and inventory gains. Diluted EPS increased 25% year over year to $0.75. Deferred revenue increased to $4.7 billion, suggesting high demand and continued product increases, especially in AI-related use cases.
The Americas accounted for more than 80% of revenue, and international markets accounted for approximately 20%. Management highlighted that the scale of demand for AI-powered networks is unparalleled as customers move large amounts of data across increasingly complex multiplanar architectures. Arista’s success is based on its EtherLink portfolio, which offers a single point of network control for automation, security, traffic engineering and telemetry. Arista networks are designed to improve the efficiency of AI accelerators, ensuring data moves faster and more reliably at scale. EtherLink fabrics are already powering some of the world’s largest AI systems, delivering full line-rate performance without hotspots, even at petabyte scale.
Additionally, the Ethernet Scale-Up Networking (ESUN) effort, which was created in partnership with industry experts through the Ultra Ethernet Consortium, aims to produce compatible standards for large-scale AI systems. EtherLink speeds are expected to increase from 800 gigabits to 1.6 terabits in the near future.
While Arista works closely with Nvidia (NVDA), the company is deliberately building a broad, open ecosystem. Its partners also include AMD (AMD), Arm Holdings (ARM), Broadcom (AVGO), OpenAI, Anthropic, Pure Storage, and Vast Data, among others.
Management emphasized that AI infrastructure includes more than just computing. Compute, memory/storage, and networking must work together seamlessly. Arista is attempting to create a stable network foundation that allows both training and inference models to run effectively at scale.
The company’s balance sheet is as strong as its revenue and results, with $10.1 billion in cash, cash equivalents and investments. It generated approximately $1.3 billion in operating cash flow during the quarter and still has $1.4 billion available under its authorized share repurchase program. The company reiterated its goal of generating at least $1.5 billion in AI-related revenue by 2025, including both front-end and back-end implementations. Looking ahead, for fiscal 2026, Arista is targeting $2.75 billion in AI center revenue as part of a broader total revenue target of $10.65 billion, implying growth of about 20%.
Management expects the total addressable market for networking to surpass $100 billion in the coming years, and Arista remains poised to capitalize on it, increasing its long-term revenue runway. Analysts covering Arista expect explosive earnings growth over the next two years. Earnings are expected to increase 26.8% in 2025 to $2.88 per share, followed by a 16.7% increase in 2026 to $3.36 per share. At 39 times forward earnings, Arista trades at a premium valuation, meaning the market is already expecting strong execution.
ANET shares are up 19% year to date, outperforming the broader market. Its average price target of $166.75 suggests 28% upside potential from current levels. However, its highest street estimate of $185 implies a potential upside of around 42% over the next 12 months.
Overall, Wall Street rates Arista stock a “Strong Buy.” Of the 24 analysts covering ANET stock, 16 have a “Strong Buy” recommendation, two rate it as a “Moderate Buy” and six suggest it is a “Hold.”
For the stock to beat current price estimates, Arista must meet or beat earnings expectations, and margins and growth must remain resilient even as competition increases. Investors willing to take on this risk might want to start with a small stake in this exceptional AI stock.
