3 Top Tech Stocks That Could Make You a Millionaire

Most investors understand that diversifying their portfolio across sectors, companies, and asset classes is the best way to minimize risk. As most veteran investors can also confirm, however, the technology sector has consistently – even if erratically – outperformed all other sectors over the course of the past three decades.

Its leadership isn’t likely to falter in the foreseeable future, either. Tech sector companies just drive too much important sociocultural change.

With that in mind, if you’re looking to become a millionaire investor, these three technology stocks could prove to be great long-term workhorses for your portfolio.

1. Taiwan Semiconductor Manufacturing

Contrary to a common assumption, chipmakers like Nvidia, Qualcomm, and Advanced Micro Devices don’t actually manufacture their own chips. Rather, they design them, but outsource their production to third-party foundries.

The only recent exception to this norm on the data processor side of the industry is** Intel**, which has continued to build and operate its own foundries, and even offers its services to make silicon for rival brands. Intel’s decision last year to push out the opening of a couple of semiconductor plants it’s building in Ohio by several years, however, underscores the complexity and costs of the foundry business.

Enter Taiwan Semiconductor Manufacturing (TSM +0.42%).

Just as the name suggests, the company is a chipmaker. This description doesn’t do it justice, though. Taiwan Semiconductor is the world’s top producer of high-performance processors (like those used in artificial intelligence data centers), and has an estimated minimum control of about two-thirds of the third-party semiconductor manufacturing market. Given the technical difficulties and costs of getting into the foundry business, it’s unlikely that the well-established Taiwan Semiconductor will lose significant market share anytime soon… if ever.

That doesn’t mean the company’s results or its stock’s performance are super consistent. For example, its shares struggled in 2022 (along with the rest of the tech sector), largely in anticipation of industry headwinds that brought the technology giant’s revenue growth to a screeching halt the following year; its top line fell by 4.5% in 2023.

Just keep your finger on the longer-term pulse of the semiconductor business and how it works. The need for newer and better (and more) semiconductors is never going away, but it’s extremely tough to break into the foundry business in a meaningful way. That leaves Taiwan Semiconductor well positioned for long-term growth.

2. CoreWeave

While the first chapter of the artificial intelligence (AI) revolution was all about computing hardware (mostly Nvidia’s), the next chapter will put the spotlight on the data center operators that make it possible for organizations to utilize AI. And among these names,** CoreWeave** (CRWV +1.51%) is arguably one of the best investment opportunities.

At a passing glance, CoreWeave may look about the same as other AI data center names. Its servers are accessed remotely and are capable of handling AI workloads, just like those of its peers.

To technologically versed experts, though, this company brings a couple of huge differences to the table.

One of these differences is that it offers so-called “bare-metal” access to its processors. By bypassing the virtualization that’s usually required of cloud-based access to off-site hardware, CoreWeave’s platforms ultimately offer its customers faster computing performance.

The company’s other competitive edge is that its platforms have been built from the ground up to specifically handle larger-scale AI workloads. Whereas many of its rivals are working with architectures that were built for a different era around older processors, CoreWeave’s tech – and its networking and data storage solutions in particular – allow for more data handling, with 50% fewer job interruptions than comparable alternatives. As large language models get even bigger and are asked to do more, these seemingly little things will matter in a big way.

And the strength of its offerings is evident in the numbers. Although last year’s 168% revenue growth will be practically impossible to top simply due to capacity and logistical (and mathematical) constraints, CoreWeave’s current revenue backlog of $66.8 billion compared to 2025’s top line of $5.1 billion speaks volumes about the growing demand for its caliber of service.

3. Alphabet

Finally, add Alphabet (GOOG 0.58%) (GOOGL 0.42%) to your list of technology stocks that could help make you a millionaire. Last quarter’s and last year’s revenue growth rates of 17% and 15%, respectively, were in line with its long-term norms, and that pattern will likely persist well into the future for one overarching philosophical reason: The company’s massive digital ecosystem allows it to enter or build any business that it views as worth getting into.

Alphabet isn’t simply the owner of the world’s most-used search engine. The company is positioned as a gatekeeper to much of the web and how people access it.

Its mobile operating system, Android, which it acquired in 2005, is now installed on over two-thirds of the world’s mobile devices (according to data from Statcounter), while Gmail is the biggest provider of free-to-use email service. YouTube is also owned by Alphabet, and Google Gemini is eating into ChatGPT’s leading share of the AI chatbot market (again, according to Statcounter). Even Google Workspace – the company’s office productivity software suite – is about as popular as powerhouse Microsoft’s Office 365 software, which includes titles like Word and Excel.

These are all different pieces of a massive revenue-bearing digital ecosystem. It’s difficult to use the internet without eventually stumbling into this ecosystem in one way or another.

Alphabet doesn’t limit itself to consumer-facing initiatives, though. Consider its foray into cloud computing: While its cloud business still isn’t as big as Microsoft Azure or Amazon Web Services, Google Cloud is currently growing faster than both of its chief rivals. Credit the success in the in-house development of its AI-capable Tensor Processing Units (TPUs)… another technological innovation funded by Alphabet’s cash cows.

The point is, Alphabet can not only afford to enter or build any business it wants to, it has also proven it can do well in the businesses it enters.
