NEW YORK, January 2, 2026, 07:07 ET — As the new year unfolds, investors are reassessing their strategies in the artificial intelligence (AI) sector, shifting focus from major AI model makers to the essential infrastructure supporting data centers. Companies like Vertiv and Arista Networks, which provide cooling, power, and networking solutions, have seen significant growth, outpacing giants such as Alphabet and Microsoft over the past three years, yet they trade at higher valuation multiples.
The changing landscape is underscored by a report from The Motley Fool, which highlights that Vertiv’s trailing twelve-month revenue grew by 70.4% over three years, while Arista’s rose by an impressive 92.8%. In contrast, Alphabet and Microsoft reported revenue growths of 37.3% and 44%, respectively. Notably, Vertiv’s net income surged by 1,250%, in stark contrast to Alphabet’s 107.2% increase and Microsoft’s 55.5% rise. This rapid growth of infrastructure providers is crucial as the demand for AI capabilities continues to escalate, directly linked to the expansion of data centers.
This focus on fundamental infrastructure is becoming increasingly relevant as the AI boom encounters potential real-world constraints. A recent column from Barron’s cautioned that power supply issues could emerge as a significant bottleneck for AI investments in 2026, potentially slowing down momentum in the sector. The publication referred to the upcoming year as a “make-or-break year” for the AI trade, emphasizing that electricity availability might play a critical role in determining the pace of AI spending.
The “pick-and-shovel” investment strategy, which refers to supplying tools during a boom rather than betting on the winners, has gained traction among investors. In the context of AI, it encompasses the provision of necessary hardware and systems, such as cooling systems and networking equipment, that ensure data centers remain operational and efficient. This approach has been highlighted as a prudent method to engage with the rapidly growing AI sector.
In a different analysis, The Motley Fool also identified large-cap companies like Alphabet, Tesla, and IBM as long-term plays in the AI space, extending beyond mere chipmakers. Alphabet was characterized as a “high floor” AI stock due to its robust advertising revenue, which amounted to $74.1 billion in the third quarter, providing financial backing for its AI initiatives. The company’s cloud platform and first-party data are seen as additional competitive advantages.
Tesla, on the other hand, was framed as a riskier bet tied to CEO Elon Musk‘s ambitions in AI and robotics, particularly with the development of its humanoid robot, Optimus, despite recent struggles in its vehicle business. Meanwhile, IBM was depicted as a dividend-oriented AI investment, boasting a yield of approximately 2.2% and a commendable 29-year streak of annual dividend increases. Analysts expect IBM’s earnings to grow at a high-single-digit annualized rate over the next three to five years, positioning it favorably in the hybrid cloud market.
As 2026 commences, the evolving priorities among investors highlight a broader understanding of the AI ecosystem. With the potential for infrastructure-related constraints looming, the focus on companies that provide the essential hardware and systems necessary for AI deployment indicates a shift towards a more sustainable investment strategy. This reorientation not only emphasizes the importance of operational fundamentals but also underscores the interconnectedness of AI advancements and the physical resources that support them, setting the stage for critical developments in the technology landscape.
