Here's How Much a $1000 Investment in Arista Networks Made 10 Years Ago Would Be Worth Today

How much a stock's price changes over time is important for most investors, since price performance can both impact your investment portfolio and help you compare investment results across sectors and industries.

FOMO, or the fear of missing out, also plays a role in investing, particularly with tech giants and popular consumer-facing stocks.

What if you'd invested in Arista Networks (ANET) ten years ago? It may not have been easy to hold on to ANET for all that time, but if you did, how much would your investment be worth today?

Arista Networks' Business In-Depth

With that in mind, let's take a look at Arista Networks' main business drivers.

Santa Clara, CA-based Arista Networks, Inc. is engaged in providing cloud networking solutions for data centers and cloud computing environments. The company offers 10/25/40/50/100 Gigabit Ethernet switches and routers optimized for next-generation data center networks.

Arista uses multiple silicon architectures across its products. At the core of the company’s cloud networking solutions is the Linux-based Extensible Operating System (EOS), which was architected to be fully programmable and highly modular.

EOS supports leading cloud and virtualization solutions, including Microsoft System Center, OpenStack and other cloud management frameworks. The company co-authored the Virtual Extensible LAN (VXLAN) protocol specification with VMware and was the first to demonstrate VXLAN integration. It has now expanded VXLAN routing and integration.

In 2015, Arista introduced CloudVision, a network-wide approach for workload orchestration and workflow automation delivering a turnkey solution for cloud networking. In 2019, Arista introduced 10 new 400G platforms. In the Leaf/Spine High Network Radix category, it now offers two new fixed 32 port 400G switches and a 128 port 100G/32 port 400G modular switch. For the Universal Leaf and Spine category of switching, the company introduced R3 series 100G and 400G products supporting up to 2.5M routes on its 7280R3 series fixed and 7500R3 series modular platforms.

Arista introduced a modular family called the 7800R3, a high-density 100G and 400G platform supporting up to 460 Tbps of system throughput. Also, it launched the 720XP Series of fixed Power over Ethernet (PoE) leaf switches with 60W PoE, enabling it to offer a complete end-to-end solution for cognitive campus Ethernet as well as the introduction of WiFi-6 wireless Access Points (APs).

The company serves five verticals, namely – cloud titans (customers that deploy more than one million servers), cloud specialty providers, service providers, financial services and the rest of enterprise. Arista’s customers include six of the largest cloud service providers based on annual revenues. In 2025, total revenues were $9 billion.

Bottom Line

Putting together a successful investment portfolio takes a combination of research, patience, and a little bit of risk. For Arista Networks, if you bought shares a decade ago, you're likely feeling really good about your investment today.

According to our calculations, a $1000 investment made in March 2016 would be worth $36,557.35, or a gain of 3,555.73%, as of March 24, 2026, and this return excludes dividends but includes price increases.

Compare this to the S&P 500's rally of 223.12% and gold's return of 246.49% over the same time frame.

Analysts are anticipating more upside for ANET.

Arista reported strong fourth-quarter 2025 results, with both the bottom and the top lines beating the respective Zacks Consensus Estimate. Innovative product launches and steady customer additions backed by the company's best-in-class portfolio strength led to top-line expansion, while steady margin improvement contributed to earnings growth. The company surpassed shipments of 150 million cumulative ports in the fourth quarter of 2025 with healthy momentum from the Arista 2.0 strategy. However, Arista faces stiff competition in cloud networking solutions, particularly in the 10-gigabit Ethernet and above. Rise in headcount, new product introduction costs, and higher variable compensation expenditures are straining margins. Its high customer concentration is a concern. A constrained supply chain environment is worrisome.

Over the past four weeks, shares have rallied 6.63%, and there have been 8 higher earnings estimate revisions in the past two months for fiscal 2026 compared to none lower. The consensus estimate has moved up as well.
