In this article, we will discuss The Next SanDisk: 9 Potential Breakout AI Stocks You Shouldn’t Miss.
It’s been months, if not years, since bears started warning that the AI bubble was about to burst. Yet AI spending continues to surge, new AI use cases keep emerging, and a growing number of companies are entering the space. Recent IPOs have also brought fresh names into the spotlight.
Many investors believe the AI rally still has years of runway as companies continue pouring billions into AI infrastructure and applications.
Bank of America’s latest monthly survey of fund managers found that about 56% of respondents believe the AI trade remains in the “boom” stage, where strong momentum and fear of missing out continue to attract investors. Only 21% said the sector has entered the “euphoria” stage, when valuations become excessively stretched and speculative.
Jim Lebenthal, Partner and Chief Market Strategist at Cerity Partners, recently said on a program on CNBC that investors should welcome the market broadening into other under-the-radar AI names amid new IPOs. He believes there are no signs that the current bull run will end anytime soon and says investors need to look for new names to continue making money from the AI rally.
“There’s no reason that I can see to think that there’s going to be a correction anytime soon, whether it’s the market overall or semiconductors or technology,” Lebenthal said. “I want everybody to consider if you, as most of us have some of these parabolas in your portfolio, it is a good time to do some risk management, not sell the entire thing, but trim some and go into other areas.”
SanDisk soared 4,600% in the past year. And for some, it was not a surprise. Wise investors spotted long before Wall Street caught on. The reason is simple: when AI data centers exploded, they needed massive amounts of memory storage. SanDisk makes the chips. Their factories were already maxed out. Supply couldn’t meet demand. So they raised prices. A lot. Profit margins went through the roof. Stock went with them.
The real question investors are asking now: What’s the next SanDisk? Which company owns a critical bottleneck that AI infrastructure can’t live without?
For this article, we reviewed extensive Reddit discussions, including long threads on potential next breakout stocks like SanDisk, and selected names that users broadly agree have strong long-term catalysts and breakout potential, excluding meme stocks. With eack stock we have also mentioned its hedge fund sentiment. Why are we interested in the stocks that hedge funds pile into?

9. Cerebras Systems (NASDAQ:CBRS)
Number of Hedge Fund Investors: N/A
Cerebras Systems (NASDAQ:CBRS) is an AI chipmaker that sells Wafer-Scale Engine (WSE-3) processors. Its customers are OpenAI and Amazon Web Services, with potential for enterprise customers down the line.
Wall Street turned bullish on the company because it makes the industry’s only commercially deployed wafer-scale AI chip. Bulls point to the company’s massive $24.6 billion backlog, which is 48 times Cerebras Systems (NASDAQ:CBRS) FY25 revenue of $510 million. The backlog is supported by a $20 billion three-year deal with OpenAI announced in January 2026. In that deal, OpenAI will deploy approximately 750 megawatts of Cerebras compute capacity through 2028, with an option for an additional 1.25 gigawatts. The company also has a collaboration with AWS for disaggregated inference announced in March 2026.
Cerebras Systems (NASDAQ:CBRS) expects revenue growth with a 120% forward topline CAGR through fiscal 2028 from fiscal 2025. This is based entirely on the OpenAI and AWS commitments. Morgan Stanley recently started coverage of the stock with a $250 price target and called it one of the most differentiated AI infrastructure companies with a first-mover advantage against Nvidia. UBS came out with a $300 price target and a Buy rating. Needham also came out with $300 and a Buy rating.
The main risk is concentration. Most of the backlog depends on OpenAI. If OpenAI changes strategy or builds its own chip, Cerebras Systems (NASDAQ:CBRS) gets hurt bad. The WSE-3 also has memory scaling limitations that could prevent it from reaching enterprise customers who want flexible GPU setups. But right now, for fast inference and token generation, the stock has real demand backing it.
8. NETLIST (OTC:NLST)
Number of Hedge Fund Investors: N/A
NETLIST (OTC:NLST) is a small-cap memory company that has caught the attention of retail investors who believe it could become the next major breakout story, similar to how SanDisk was perceived years ago. The company designs, manufactures, and sells high-performance memory subsystems for AI data centers, HPC environments, and enterprise applications. Its primary customers are the hyperscalers desperate for memory in their AI infrastructure buildouts, and enterprise data center operators and HPC facilities worldwide.
What makes NETLIST (OTC:NLST) particularly compelling is its portfolio of over 200 patents worldwide related to hybrid memory, storage-class memory, and DDR-related technologies—intellectual property that becomes increasingly valuable as the AI revolution scales.
Why does this patent portfolio matter so much? These patents and the company’s technology are foundational to the infrastructure powering artificial intelligence. As hyperscalers race to build out massive data centers for AI training and deployment, memory bottlenecks have become the critical chokepoint. NETLIST’s (OTC:NLST) patents cover technologies that are essential to solving these bottlenecks.
7. Digi Power X Inc (NASDAQ:DGXX)
Number of Hedge Fund Investors: 11
Digi Power X Inc (NASDAQ:DGXX) is an energy infrastructure and AI data center company. It makes modular Tier III data centers through its ARMS platform and provides enterprise-grade GPU compute services through its NeoCloudz portal. Its customers are AI infrastructure companies like SubQ AI and Cerebras Systems.
A Tier III data center is enterprise-grade infrastructure with redundant power systems, cooling, and multiple independent distribution paths. It supports 99.99% uptime, which is what AI companies need for continuous computing operations.
Digi Power X Inc’s (NASDAQ:DGXX) strategy centers on pairing secured, grid-connected power capacity with modular, AI-optimized data center infrastructure. In April 2026, DGXX announced its first AI revenue contract with SubQ AI worth approximately $19.6 million. In May, the company signed a 40 megawatt AI colocation agreement with Cerebras Systems valued at $1.1 billion for the initial 10-year term, with potential to reach $2.5 billion total.
However, Q1 2026 revenue showed declines to $6.8 million from $9.3 million a year prior amid the planned wind-down of legacy cryptocurrency mining operations. The positive side is that adjusted EBITDA turned positive at $1.1 million versus negative $1.3 million in Q1 2025.
Management outlined aggressive revenue run-rate targets: $300 million annually for 2027, $450-500 million for 2028, and $800 million to $1 billion for 2029. These targets depend on executing debt-financing plans.
6. POET Technologies (NASDAQ:POET)
Number of Hedge Fund Investors: 14
POET Technologies (NASDAQ:POET) is up about 90% so far this year but Redditors believe the stock can break out much further. POET makes optical photonics solutions for AI data centers. The company is at a critical inflection point right now. It needs to transition from proving the technology works to actually manufacturing it at scale.
POET Technologies’ (NASDAQ:POET) main play is External Light Source modules that can be deployed separately from the rest of the data center switching system. This is important because it reduces the risk if co-packaged optics adoption gets delayed.
Q1 revenue jumped 194% year over year. Consensus indicates POET Technologies (NASDAQ:POET) will deliver 10x annual revenue growth in 2027, going from roughly $10 million in 2026 to nearly $100 million in 2027. That’s the target management needs to hit.
The company’s flagship product, called the Optical Interposer, reshapes data transmission by enabling much faster data transfer with just a fraction of the power compared to copper. That’s critical for AI data centers that need more power and speed. Right now power and cooling are the biggest bottlenecks in data center buildout.
However, the stock trades at a 62x premium to peers on forward price-to-sales. The valuation is expensive, which means POET has little room for error.
While we acknowledge the potential of POET to grow, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and have limited downside risk. If you are looking for an AI stock that is more promising than POET and that has 100x upside potential, check out our report about the cheapest AI stock.
