The AI spending spree is driving phenomenal growth for Nvidia and Sandisk

While Nvidia is part of the Magnificent Seven, it is one of the biggest beneficiaries of this group’s massive capital spending. Nvidia’s chip systems are the cornerstone of the AI infrastructure that’s being built by the major hyperscalers in the U.S. When Nvidia revealed its next-generation Vera Rubin AI processors earlier this year, the company noted that this platform will be deployed widely by the top four hyperscalers in the U.S.

Additionally, there is strong demand for Nvidia’s Vera Rubin processors from pure-play AI companies such as OpenAI and Anthropic. At the same time, AI start-ups, neocloud providers, and server makers are also expected to deploy these chips on a big scale. The good part is that the strong demand for Nvidia’s AI chips is poised to translate into stronger growth for the company.

Nvidia reported 85% year-over-year revenue growth in the first quarter of fiscal 2027 (which ended on April 26). Its $91 billion revenue estimate for the current quarter points toward a stronger jump of 95% from the year-ago period. So, it is easy to see why analysts are predicting a larger increase of 88% in its earnings per this fiscal year to $8.94 per . That’s well above the 60% growth it delivered in the previous fiscal year.

With the stock trading at just 25 times forward earnings, a discount to the tech-laden Nasdaq-100 index’s forward earnings multiple of 27, investors are getting a great deal on Nvidia stock right now. After all, it should ideally trade at a premium after a year, given its market-beating earnings growth potential.

Similarly, Sandisk is also trading at an attractive 22 times forward earnings. The storage specialist’s bottom line has been growing exponentially, as the demand for its NAND flash storage solutions is exceeding supply. Importantly, the AI boom should ensure that storage demand continues to grow at an exceptional pace.

According to a research report, the AI-focused storage market’s revenue could increase from $36 billion last year to almost $322 billion in 2035. That’s not surprising, as supporting AI workloads such as training models and running inference applications requires large datasets that must be quickly fed to AI accelerators in data centers and at the edge.

This explains why McKinsey is estimating 35% annual growth in sales of enterprise solid-state drives (SSDs) that Sandisk manufactures through 2030. The consulting firm notes that AI training needs will drive an 11x increase in SSD content per server between 2024 and 2030, while AI inference will drive a 7x jump in the same.

Given that the memory chip shortage could continue until 2030, it is easy to see why Sandisk’s earnings are set to rise at a parabolic pace from fiscal 2025 levels of $2.99 per .

But which stock should you be buying right now?

It isn’t too difficult to see which one of these two AI stocks is worth buying hand over fist right away. While both of them are growing at solid rates, Sandisk’s growth is outpacing Nvidia’s significantly. Of course, Nvidia is anticipated to deliver healthy double-digit earnings growth over the next three years, but its average growth rate isn’t expected to be anywhere close to Sandisk’s.

Additionally, Sandisk has a slightly cheaper forward earnings multiple. If Nvidia and Sandisk were to trade at an identical 30 times forward earnings after three years, the latter’s stock price upside will be much higher. That’s why Sandisk looks an ideal investment for anyone looking to build a million-dollar portfolio. The key role that memory chips are playing in AI infrastructure should ensure that Sandisk’s red-hot earnings growth continues beyond the next two to three years, paving the way for multibagger gains in the long run.
