As artificial intelligence (AI) continues to transform industries, a few blue-chip stocks like Amazon (AMZN), Nvidia (NVDA), and Microsoft (MSFT) dominate headlines. However, this does not always imply that they are the only viable investments in AI. 

Under-the-radar stocks, on the other hand, may be reasonably priced and have room for more expansion. 

Here are some lesser-known companies gaining traction in the AI space.

#1: Arista Networks

Valued at $116.5 billion, Arista Networks (ANET) is a leading provider of high-performance networking solutions for large data centers, cloud computing environments, campuses, and enterprise networks. The stock has experienced short-term volatility this year, primarily due to concerns about customer concentration, falling 21.4% year to date. Nonetheless, Arista’s long-term outlook remains positive, with Wall Street expecting the stock to rise as much as 50% from current levels. 

As AI workloads require more from network infrastructures, Arista has strategically positioned itself to meet these demands. Ethernet-based solutions from the company are gaining popularity over traditional InfiniBand systems due to their scalability and cost-effectiveness. Arista began 2025 with a strong performance in Q1, reporting record-breaking revenues of $2 billion, up 27.6% annually. Adjusted net income increased 30% to $0.65 per share, exceeding consensus expectations. Management highlighted that adjusted gross margin went slightly above expectations to 64.1%, supported by an efficient supply chain and a healthy mix of enterprise and cloud customers.

In the Q1 earnings call, CEO Jayshree Ullal emphasized Arista's growing presence in AI and cloud networking. The company expressed confidence in meeting its $750 million AI front-end goal by 2025. Arista aims to be the leading scale-out network provider for Nvidia's evolving GPU (graphics processing units) and AI accelerator roadmap, with its Etherlink portfolio serving as a key differentiator in large AI cluster performance.

The company ended the quarter with a total of $8.15 billion in cash, equivalents, and marketable securities. During the quarter, it spent $787.1 million on stock repurchases, its largest repurchase to date. It also announced a new $1.5 billion stock buyback authorization, boosting investor confidence in long-term growth.

Even with ongoing macroeconomic volatility and tariff uncertainty, Arista remains optimistic. With growing opportunities in AI, cloud, and campus infrastructure, the company is confident of meeting and possibly exceeding the $10 billion revenue milestone ahead of schedule.

Analysts who cover the stock remain optimistic about the company’s future. Revenue and earnings are expected to rise by 19.6% and 12.4%, respectively, in 2025, with further double-digit growth in 2026. Arista stock appears to be expensive, trading at 31 times forward earnings, but this reflects investors’ confidence in the company’s long-term growth prospects. The company’s strategic investments in AI networking, combined with its strong financial health, position it well to capitalize on new opportunities.

On Wall Street, Arista stock holds an overall rating of “Moderate Buy.” Of the 22 analysts covering the stock, 14 rate it as a "Strong Buy," two as a "Moderate Buy," and six recommend a “Hold.” The stock's average target price of $111.68 suggests a potential upside of 27% from current levels, while the highest price estimate of $130 indicates a possible 50% rally over the next 12 months.

#2: Vertiv Holdings

Valued at $41.6 billion, Vertiv Holdings (VRT) specializes in designing, manufacturing, and servicing infrastructure technologies for data centers, communication networks, and commercial and industrial environments. Its product portfolio comprises power management systems, thermal management solutions, and IT management tools. Vertiv’s stock is down 4.4% year-to-date.

The surge in AI applications has increased the demand for high-density data centers. Vertiv is capitalizing on this trend by offering advanced cooling and power solutions specifically designed for AI workloads. The company posted a strong first quarter of 2025. Vertiv reported a 49% increase in earnings to $0.64 per share, exceeding expectations by $0.04, thanks to 25% organic net sales growth and a record book-to-bill ratio of 1.4x.

In the Q1 earnings call, CEO Giordano Albertazzi stated that the company’s visibility into the data center market, particularly AI infrastructure, gives management confidence not only for 2025, but also for the long term. Vertiv ended the quarter with nearly $1.5 billion in cash and cash equivalents and $265 million in adjusted free cash flow. 

Management stated that Vertiv has spent the last two years developing a resilient, geopolitically diverse supply chain. The company operates with strong local capacity in the U.S. and Mexico and has begun relocating production away from high-tariff regions. 

Vertiv raised its 2025 sales growth guidance to 18%, citing strong demand signals from AI and hyperscale customers. The midpoint EPS guidance of $3.55 remains unchanged, implying 25% year-over-year growth, despite the company expecting a $50 million headwind from U.S.-China tariff impacts in the second quarter. Analysts predict revenue growth in the same range, with earnings rising by 25% by 2025. 

Currently, Vertiv stock is trading at 30 times forward earnings. While the global tariff environment is complex, the company’s proactive supply chain strategy and solid financial position it for continued success in 2025 and beyond.

On Wall Street, Vertiv stock holds an overall rating of “Strong Buy.” Of the 19 analysts covering the stock, 15 rate it as a "Strong Buy," one as a "Moderate Buy," and three recommend a “Hold.” The stock's average target price of $119.50 suggests a potential upside of 9.1% from current levels, while the highest price estimate of $150 indicates a possible 37% rally over the next 12 months.
