If you are looking for AI stocks beyond NVIDIA in 2026, you are not alone. NVIDIA dominates headlines, but the AI value chain extends far beyond GPU chips. From networking to cooling to enterprise software, several underrated AI stocks to buy are quietly delivering massive growth while attracting far less attention.
Why Diversifying Beyond NVIDIA Matters Now
NVIDIA trades at roughly 40x earnings with a $4.8 trillion market cap. Much of the AI upside is already priced in.
The real opportunity lies in the supply chain. Hyperscalers like Microsoft, Amazon, Alphabet, and Meta plan to spend over $700 billion on AI infrastructure in 2026. That capital flows to networking, power, cooling, and software platforms that most retail investors overlook.
Palantir Technologies: The AI Software Platform Play
Why PLTR stands out in 2026
Palantir is no longer just a government contractor. Its Artificial Intelligence Platform (AIP) enables businesses to deploy custom AI workflows using their own data, transforming it into an enterprise AI powerhouse.
Palantir delivered 70% year-over-year revenue growth in Q4 2025, reaching $1.41 billion. U.S. commercial revenue surged 137%.
Key metrics to watch
Management guided for $7.18 to $7.20 billion in 2026 revenue, roughly 61% growth. According to IBTimes, 19 analysts cover the stock with a consensus Buy rating and an average price target near $195.
The risk is valuation. PLTR trades at over 200x earnings, so execution must remain flawless.
Arista Networks: Networking the AI Data Center Buildout
The picks-and-shovels networking play
Every AI GPU cluster needs ultra-fast networking to function. Arista Networks supplies the high-speed Ethernet switches that connect AI training clusters at cloud titans worldwide.
Arista reported $9 billion in fiscal 2025 revenue, up 28.6% year over year, with operating margins around 42.8%.
2026 growth trajectory
Management raised its 2026 outlook to $11.25 billion in revenue with a 46% operating margin. AI networking revenue alone is projected to hit $2.75 to $3.25 billion, up from $1.5 billion in 2025. That is near-doubling in one year.
Vertiv Holdings: Powering and Cooling the AI Infrastructure
The physical layer of AI
AI chips generate enormous heat. A standard data center rack consumed 10 to 15 kW in 2023. By early 2026, AI clusters push 120 to 150 kW per rack. Vertiv is the leading provider of power management and liquid cooling solutions for these facilities.
According to Motley Fool, Vertiv stock gained 64% year to date in 2026, yet analysts still maintain a Buy rating.
Backlog signals continued momentum
Q4 2025 orders climbed 252%, and backlog surged 109% to $15 billion. Management targets $13.25 to $13.75 billion in 2026 revenue. The data center cooling market is projected to grow at a 22.3% compound annual rate through 2033.
Vertiv is one of the best AI investments not NVIDIA because it benefits regardless of which chip maker wins the GPU race.

ServiceNow: Enterprise AI Adoption at Scale
AI-native workflow automation
ServiceNow is embedding artificial intelligence across its entire enterprise platform. Its Now Assist product crossed $600 million in annual contract value by end of 2025 and is on track to reach $1 billion by end of 2026.
While infrastructure stocks benefit from capex spending, NOW profits from the enterprise adoption wave as companies deploy AI into daily operations.
Subscription revenue keeps compounding
Management guided for 19.5 to 20% subscription revenue growth in 2026, targeting $15.53 to $15.57 billion. The stock has pulled back roughly 47% from its July 2025 peak, creating a potential entry point for long-term investors.
How to Build Diversified AI Exposure in Your Portfolio
Building a balanced AI portfolio means investing across four layers of the value chain.
Chips and compute: NVIDIA remains the leader and your core AI holding.
Networking: Arista Networks connects the GPU clusters that make AI possible.
Physical infrastructure: Vertiv powers and cools the data centers running AI workloads.
Software and platforms: Palantir and ServiceNow monetize AI at the application layer.
A diversified approach reduces concentration risk. Review your AI exposure today. Check your portfolio in Gotrade to see where you stand across these layers, and consider whether you are too concentrated in any single name.
The AI boom extends well beyond NVIDIA. Palantir, Arista Networks, Vertiv Holdings, and ServiceNow each capture a different segment of the multi-trillion-dollar AI buildout. Open your watchlist and start tracking these names today.
