What does Arista Networks, Inc. (ANET) do?

Arista Networks designs and sells high-performance Ethernet switches and networking software for cloud, enterprise, and AI data centers. The company is the leading independent vendor of cloud-scale data center networking, with Microsoft Azure and Meta Platforms among its largest customers. Arista's switches use merchant silicon (primarily Broadcom's Tomahawk and Jericho ASICs) combined with the company's own EOS (Extensible Operating System) software, giving customers programmability and flexibility that Cisco's traditional integrated approach didn't offer.

AI data centers have become a major growth driver because they require dramatically more networking bandwidth than traditional cloud workloads. Each AI training rack connects to thousands of others at high speeds; Arista's high-end 800-gigabit Ethernet switches are positioned for this market. The numbers show it: revenue grew from about $7.0 billion in 2024 to about $9.0 billion in 2025, and trailing revenue reached roughly $10.5 billion after a second quarter of 2026 in which revenue rose about 38% year over year to around $3.0 billion and EPS of $1.02 beat the $0.89 consensus. Margins are unusually high for hardware, with a 63% gross margin and a 45% operating margin. The stock is up about 35% in 2026 and about 24% over the past year, though it has slipped about 10% over the last month from a 52-week high near $217. Founded in 2004 by Andy Bechtolsheim and Jayshree Ullal, headquartered in Santa Clara, California. Jayshree Ullal has been CEO since 2008.

What's driving Arista Networks, Inc. (ANET)?

1. AI back-end networking.

AI training racks require massive networking bandwidth between GPUs. Arista has positioned itself as the leader in cloud-scale Ethernet for AI workloads, with Microsoft and Meta as major customers. The AI networking opportunity has materially expanded Arista's addressable market, and growth has sped up rather than slowed: year-over-year revenue growth reached about 38% in the second quarter of 2026, and analysts expect about 44% in the third quarter on revenue near $3.33 billion.

2. Campus and enterprise expansion.

Beyond cloud data centers, Arista has expanded into enterprise campus networking, competing more directly with Cisco. This is a slower-growth, larger-margin market that diversifies the customer base.

3. EOS software differentiation.

Arista's EOS network operating system is the structural moat. Customers value the programmability and automation it enables, particularly at hyperscale. Software updates are non-disruptive, which matters when uptime is the primary metric.

4. Customer concentration management.

Microsoft and Meta have historically been around 40% combined revenue. Arista has been working to diversify the customer base; concentration risk is the main story risk. Consensus calls for about $12.7 billion of revenue in 2026 and about $16.4 billion in 2027, which assumes hyperscaler AI spending keeps rising.

What are the risks to Arista Networks, Inc. (ANET)?

Customer concentration (Microsoft and Meta). NVIDIA's push to displace Ethernet with InfiniBand for AI workloads, and to integrate networking into its complete-system offerings, is competitive pressure on the merchant-silicon Ethernet ecosystem. Valuation is a risk in its own right: at about 57x trailing earnings and over 21x sales, the stock prices in continued 30%+ growth, so any guidance that implies a slowdown in hyperscaler AI capex could compress the multiple quickly. The roughly 10% pullback over the month before the November 3 report shows how sensitive the shares are to sentiment about AI spending.

What is the Arista Networks, Inc. (ANET) forecast?

29 analysts publish price targets on ANET, averaging $245.14 against a $176.99 price as of October 2026, or +38.5%. The published targets run from $190.00 to $290.00, a moderate spread, and the ratings split 31 buy, 1 hold, 0 sell. Over the last six months there have been 10 raises and 0 cuts among the published actions. A price target is what an analyst published on a date, not a prediction, and sell-side ratings skew positive across the whole market.

Is ANET a buy or a sell?

We give no verdict on Arista Networks, Inc.. Both cases are real, which is why the question is contested at all, so here is the strongest version of each.

The case for buying. AI back-end networking. AI training racks require massive networking bandwidth between GPUs. The most optimistic published target, $290.00, assumes this works close to its best case.

The case against. Customer concentration (Microsoft and Meta). The most pessimistic target, $190.00, is roughly what ANET is worth if this bites instead.

Has Arista Networks, Inc. (ANET) split its stock?

Yes. Arista Networks, Inc. (ANET) has had 2 share splits in the last 10 years:

  • 4:1 on November 18, 2021, so every share held became 4 shares.
  • 4:1 on December 4, 2024, so every share held became 4 shares.

A split changes the share count and the price per share and leaves the value of a holding unchanged. Someone holding $1,000 of ANET the day before the 4:1 split held $1,000 the day after, in more shares at a proportionally lower price. Historical prices from before the date are normally shown split-adjusted, which is why a long-run chart shows no cliff.

Splits matter mainly because they make older price figures confusing to compare by hand, and because a board choosing to split is usually signalling that the price has run up far enough to feel awkward for smaller buyers. Neither is a reason to buy or sell.

How is Arista Networks, Inc. (ANET) valued? (approximate, October 2026)

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Arista Networks, Inc.'s investor relations page or your broker.

  • Revenue (TTM): ~$10.5 billion (Q2 2026 ~+38% YoY)
  • Operating margin: ~45%
  • Net income (TTM): ~$4.0 billion
  • EPS (TTM / Q2 2026): ~$3.17 / $1.02 vs $0.89 expected
  • P/E (trailing / forward): ~57x / ~35x
  • Market cap: ~$228 billion
  • Dividend yield: None (no dividend; share buybacks instead)
  • Free cash flow (TTM): ~$3.9 billion
  • Cash on balance sheet: ~$13.3 billion (no debt)

Arista trades at a substantial premium reflecting the AI networking story and the company's history of consistent execution, with four straight quarters of EPS beats. At about $180 the stock is roughly 57x trailing and 35x forward earnings, below the average analyst target near $245. The valuation is sensitive to customer concentration; a major customer pause in AI capex would compress the multiple significantly. Next up is the November 3, 2026 report, where consensus is about $1.08 of EPS on $3.33 billion of revenue.

ANET is now among the larger US networking companies by market cap, comparable to or larger than legacy networking leaders like Cisco on certain metrics.

Does Arista pay a dividend?

+

No. Arista has not paid a dividend historically and has prioritized reinvestment and share buybacks. The company has been a meaningful buyback returner during the AI cycle, and it carries about $13.3 billion of cash with no debt. A future dividend has been speculated about but not announced.

How is Arista different from Cisco?

+

Both make data center networking switches. Cisco is much larger and has broader enterprise networking and security exposure (campus networking, security, Webex). Arista is concentrated specifically on cloud and AI data center networking, with proprietary software (EOS) on merchant silicon (Broadcom). Arista has won meaningful share at hyperscalers; Cisco maintains stronger presence in enterprise campus networks.

Should I own Arista directly or through QQQ?

+

Both are common approaches, and the choice depends on your own thesis. Direct ANET ownership gives concentrated AI networking exposure with full upside and downside on hyperscaler AI capex. QQQ includes ANET at smaller weight along with broader Nasdaq-100 tech. Some investors hold both: direct ANET for AI networking conviction plus QQQ for diversified tech exposure. ANET's customer concentration (Microsoft, Meta) makes it higher-volatility than diversified tech ETFs. Walnut is not an investment adviser.
