Artificial intelligence (AI) may be one of the best investing opportunities of our lifetimes. Several leading AI stocks have produced fivefold and tenfold returns over the past five years, but Sandisk’s (NASDAQ: SNDK) nearly 4,000% gain over the past year highlights the possibilities
Investors who want to maximize their returns in this industry shouldn’t focus on yesterday’s winners. They should set their sights on smaller companies operating in the industry and gaining market share. These three millionaire-maker artificial intelligence stocks fit the description nicely
Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same “Total Conviction” signal is flashing for a company 1/100th the size of Nvidia. Continue »
Cipher Digital
Cipher Digital (NASDAQ: CIFR) is a neocloud provider that offers AI capacity to tech giants. It signs long-term deals with tenants that secure high cash flow for years to come, and demand for Cipher Digital’s services continues to surge
The company announced that it had signed a third deal with a hyperscaler tenant for one of its AI data center campuses. Meanwhile, the company continues to build more AI data centers to serve more customers
Cipher Digital has more than four gigawatts in its pipeline, and that AI capacity can become quite lucrative when it’s all online. Amazon agreed to a 15-year deal with Cipher Digital for AI capacity on Amazon Web Services. That deal includes 300 megawatts of capacity for $5.5 billion, or approximately $367 million per year
Cipher Digital can support more than 10 deals just like that one after its AI data centers are fully built. That long-term thesis keeps many investors hooked, even as the company raises substantial capital to build its facilities. Notably, Cipher Digital has a lower-cost business model than other neocloud providers such as Iren and Nebius. Cipher Digital provides the facilities, but hyperscalers are responsible for bringing their own AI chips, which reduces Cipher Digital’s operating expenses
Silicon Motion Technology
Silicon Motion Technology (NASDAQ: SIMO) benefits from the same tailwinds as Sandisk. It’s a memory play that specializes in NAND flash controllers, while Sandisk makes most of its money from NAND flash chips. The stock has already more than tripled year to date, but its fundamental strength and guidance suggest it is still overlooked.Â
The company showed some momentum in its Q4 2025 results. Sales increased by 15% sequentially, and the company guided for up to $306 million in Q1 revenue
