Everyone's Buying NVIDIA, but 2 Smaller AI Stocks Could Soar Higher

Read MoreHide Full Article

Key Takeaways

  • Western Digital expects stronger Q4 FY2026 revenues and higher margins on robust AI storage demand.
  • Seagate projects higher Q4 FY2026 revenues, backed by growing data-center storage demand and cash flow.
  • Western Digital and Seagate project strong earnings growth as AI storage demand remains robust.

The boom in artificial intelligence (AI) has led to persistent demand for NVIDIA Corporation’s (NVDA - Free Report) state-of-the-art AI hardware, including graphics processing units and Blackwell chips. That demand propelled NVIDIA to become the world’s most valuable company, with a market capitalization of over $4 trillion, and its stock has delivered strong returns over the past few years.  

However, NVIDIA’s growth has led to the company trading at a premium in comparison to most of the other semiconductor players, leaving little room for disappointment if growth derails. A slowdown in AI infrastructure spending by hyperscale cloud providers could impact NVIDIA’s revenue and earnings growth, while competition from rivals like Advanced Micro Devices, Inc. (AMD - Free Report) continues to increase.  

At the same time, U.S. export curbs on cutting-edge AI chips to China have constrained NVIDIA’s entry to a key market, potentially pressuring its margins. Additionally, NVIDIA remains exposed to supply-chain disruptions due to its dependency on Taiwan Semiconductor Manufacturing Company Limited (TSM - Free Report) for advanced chip production amid ongoing geopolitical tensions. 

Given these challenges, it’s becoming increasingly difficult for NVIDIA to meet sky-high expectations. Thus, investors seeking AI exposure should look for much smaller companies with greater room for expansion. Notable among them are Western Digital Corporation (WDC - Free Report) and Seagate Technology Holdings plc (STX - Free Report) , whose shares have soared 662.8% and 464.5%, respectively, over the past year, outpacing NVIDIA’s gain of 22.6%. 

Both Western Digital and Seagate stand to gain from the rapid growth in AI-driven demand for data storage. Let’s take a closer look at the key catalysts that could drive further upside in these AI stocks –  

Western Digital’s AI Storage Boom Could Drive Further Upside 

Rising demand for high-value enterprise hard disk drives and a favorable pricing environment have created a solid growth runway for Western Digital. The company’s revenues totaled $3.34 billion in the fiscal third quarter of 2026, up 45% year over year, according to the company’s press release.

Furthermore, the company expects revenues for the fiscal fourth quarter of 2026 to be about $3.65 billion, plus or minus $100 million. The upbeat guidance reflects robust demand for AI infrastructure, with cloud providers and enterprise customers continuing to invest in high-capacity storage to meet increasing AI workloads. 

In the fiscal third quarter, Western Digital’s non-GAAP gross margin rose to 50.5% from 40.1% in the prior-year period. The company projects further margin expansion, with fiscal fourth-quarter non-GAAP gross margin expected to reach 51-52%. The improving gross margin is providing Western Digital with greater financial flexibility to invest in research and development, enhance earnings growth and create long-term value for shareholders. 

As a result, the company’s expected earnings growth rate for the current year is 104.1%. The Zacks Consensus Estimate of $10.06 for WDC’s earnings per share (EPS) is up 54.8% year over year.

Seagate’s AI Infrastructure Play Gains Momentum Amid Rising Demand 

Seagate is well-positioned to sustain its growth momentum, banking on rising data-center storage demand, expanding margins, and robust cash flows. These favorable trends could provide the required upside for Seagate’s shares, strengthening its position as a potential beneficiary of the AI infrastructure boom. 

For the fiscal fourth quarter of 2026, Seagate expects revenues of around $3.45 billion, plus or minus $100 million, more than the $3.11 billion reported in the fiscal third quarter of 2026, according to investors.seagate.com.   

Moreover, a non-GAAP gross margin of 47% in the fiscal third quarter reflected improved operational execution and enhanced profitability. Additionally, the company’s free cash flow of $953 million in the fiscal third quarter showcased the strength in its core business.  

Supported by these trends, Seagate’s expected earnings growth rate for the current year stands at 84.3%, while the Zacks Consensus Estimate of $14.93 for STX’s EPS represents a 47.5% increase from the prior-year period.
