Global markets have become highly volatile in recent days as the Iran war drives oil prices higher and heightens geopolitical uncertainty. As a result, the benchmark S&P 500 index is down roughly 4.3% (as of March 24, 2026) since the conflict began. Investors have been reducing exposure to equities, including high-growth technology stocks, and instead shifting capital toward safe-haven assets.
That shift in sentiment is weighing on artificial intelligence (AI) infrastructure stocks, including Arista Networks (NYSE: ANET), whose shares trade down almost 19% from the 52-week high set in November 2025. However, this pullback appears to be driven mostly by macroeconomic uncertainty rather than company-specific weakness.

Against that backdrop, here's why Arista Networks appears to be an exceptional play in 2026.
The one reason: Arista is powering networks in data centers
The biggest reason Arista is quietly winning the AI race is its critical role in enabling high-speed, low-latency data center networking that allows thousands of GPUs to function as a single system. As AI networks have grown larger and more complex, managing data congestion, latency, and massive data flows has become increasingly challenging.
Arista's recent financials have been stellar. The company reported fiscal 2025 (ending Dec. 31, 2025) revenue of $9 billion, up 28.6% year over year, with operating margins of around 42.8%. Cloud providers and AI companies accounted for 48%, enterprise and financials accounted for 32%, while AI and specialty providers accounted for 20% of total fiscal 2025 revenue. The diversified customer base demonstrates that the company does not rely excessively on any single industry or company. Arista now expects its AI networking revenue to almost double year over year to $3.25 billion in 2026.
Arista's networking technology enables extremely fast communication at 10-gigabit to 800-gigabit speeds, with 1.6-terabit systems emerging to support next-generation AI workloads. At the same time, Arista also benefits from the industry's shift away from proprietary to open, Ethernet-based networking architectures.
