A look at the numbers will show you why. After reaching $196.63 billion in 2023, the global AI market is projected to hit $1.8 trillion by 2030. This rapid growth makes AI one of the most promising long-term growth opportunities in the stock market.
Marvell Technology (MRVL)
Specializing in data infrastructure solutions, Marvell Technology produces chips for networking, cloud, and storage. For years, it lagged behind bigger names, but its expansion into custom AI chips and networking hardware has changed its story and made it into one of the most promising semiconductor players in the AI era. The company manufactures application-specific integrated circuits (ASICs) and electro-optics products, both of which have become essential for the rapid scaling of AI infrastructure.
Marvell closed fiscal 2025 (ending Feb. 1) with revenue growth of just 5% to $5.77 billion, alongside a GAAP net loss of $1.02 per share. This weak performance was due to declines in several end markets such as enterprise networking, carrier infrastructure, and consumer devices. But in fiscal 2026, things changed. The first quarter (ending May 3) saw the company’s revenue rise by 63% year over year to $1.89 billion. Meanwhile, GAAP net income improved to $0.20 per share, reversing a loss of $0.25 per share the year before.
Not resting on its oars, the company is building on this momentum by already working with clients on next-generation custom AI chips. This way, the growth trajectory can continue.
Due to its thirst for more and the long-term demand from cloud providers and AI infrastructure, Marvell makes a very promising buy. The company projects its AI-focused addressable market will expand from $21 billion in 2023 to $75 billion by 2028. At the end of 2023, it controlled about 10% of this market, with some third-party estimates suggesting its share had already climbed to 15%. The goal now is 20% or more, which could translate to over $7.5 billion in annual AI revenue within three years, an improvement over fiscal 2025’s $1.5 billion.
With AI pushing Marvell Technology, its stock is set to maintain tremendous growth levels over the years. It is important, however, to note that demand for semiconductors is cyclical. This can push down revenue during downcycles. But this should not stop the company from maintaining elevated growth in earnings in the coming years.
Micron Technology (MU)
Micron Technology is another semiconductor player. They focus on memory chips, which are critical for training large AI models and handling the data-intensive workloads of modern applications. The company’s memory solutions include DRAM, NAND, and high-bandwidth memory (HBM). As AI adoption grows across various sectors, demand for these chips is on a speedy rise, and it is written all over the company’s financial performance.
In 2024, annual revenue climbed to $25.1 billion, marking a 61.59% increase from 2023. Sales are projected to grow another 41% to $35.5 billion. With a strong run so far in 2025. Q3 sales came in at a record $9.3 billion, a 37% increase from the previous year’s $6.81 billion.
What makes Micron especially interesting is its valuation. With a forward price-to-sales multiple of 2.69, it trades well below the sector average of 6.69. This means you can hold a stock standing right in the middle of many transformative tech trends, without paying the sky-high premiums attached to other top AI names.
While Micron is a great buy due to its superior scale, promise of AI growth and valuation, there is some risk in memory market price volatility and margin pressure. But these are pretty common in the industry and do not affect the stock’s strong position for long-term growth.
Palantir Technologies (PLTR)
Palantir focuses on the software layer of AI. With platforms that allow governments and corporations to integrate sprawling datasets and apply AI models into real-life workflows, the company’s revenue has been on a steady climb, with Q2 2024 revenue up 27% to $678 million. This market value has grown to almost 400 billion and might even be headed towards a $500 billion valuation this year.
Palantir’s potential for growth is massive, as its Artificial Intelligence Platform (AIP) is gaining traction across both government and commercial sectors. With high-profile clients including the U.S. Department of Defense, Morgan Stanley and Merck & Co., Inc., the stock continues to soar higher and has gained over 150% this year. Short interest in it has also been falling, an indication that bearish investors might be giving up and perhaps becoming believers.
For all its promise, the stock appears overvalued, but the rich valuation will eventually yield impressive long-term gains for investors who do not mind a pricey buy.
Amazon (AMZN)
Beyond the cloud, AI also drives Amazon's logistics optimization, product recommendations, Alexa's natural language processing (NLP), and the growing market for both SFW and NSFW AI chatbots for sexting, as well as virtual assistants that rely on AWS infrastructure. Beyond the cloud, AI also drives Amazon’s logistics optimization, product recommendations, and Alexa’s natural language processing (NLP).
The company saw its stock drop 10% from its highs after reporting slower growth in its cloud computing division compared to the competition. As of August 4, shares of Amazon trade 13% below their peak from February. However, it remains a good investment in the long run and a smart buying opportunity, as it is set to rise for the rest of the decade.
With its overall revenue pushing past $670 billion, there is still plenty of room for the company to keep growing its sales in the years to come. By 2030, it is projected to have a much larger market cap.
When you consider these factors alongside the fact that it also has a cheaper valuation than some of its peers like Nvidia or Palantir, at a forward price-to-earnings ratio of 33, you will realize why many investors have Amazon in their stock portfolio. There are risks in regulatory pressure and cloud competitions from Microsoft Azure and Google Cloud. But Amazon is and will remain a dominant tech leader in the years to come. Therefore, patient investors will surely be rewarded over the long term.
NVIDIA (NVDA)
When it comes to AI hardware, Nvidia is a leader. As one of those who benefited directly from the AI boom, the company’s GPUs are the backbone of training and inference for large language models and other AI workloads. Hence, there is increasing demand for its chips, which saw the company report $39 billion in data center revenue in 2024, a 73% year-over-year increase.
One of the things that gave Nvidia a spot on this list is its ecosystem. Aside from GPUs, the company moved into a full-stack approach with networking hardware, software libraries and next-generation AI-focused silicon. Further helping its case are its partnerships with leading cloud providers such as Amazon Web Services, Google Cloud and Microsoft Azure. Thanks to these partnerships, Nvidia’s AI offerings can be more accessible to developers and companies.
The stock’s price-to-earnings ratio makes for quite a tough consideration, especially when you think about the export restrictions the U.S. imposed on the sales of advanced chips to China. Regardless, it makes a solid AI investment. P/E ratios do not automatically determine the value of a stock, after all.
Alphabet (GOOG)
The parent company of Google, Alphabet, is another company you can bank on when it comes to AI investment. Its AI initiatives go across its business from AI Overviews into Google Search and YouTube to the advanced AI solutions in Google Cloud. And these AI moves are paying off. In Q2 2024, Google Cloud revenue grew by 29% to $10.3 billion.
Alphabet’s revenue potential is deep, as it also owns DeepMind, one of the world’s leading AI research labs. The company’s diversified business model makes it well-positioned for long-term growth. Some investors worry, however, about the potential slowdown in ad revenue Google Search faces with the rise of AI (ironically) and how it is changing internet search.
Final Thoughts about Investing in the Future of AI
Companies driving the AI revolution today hold massive opportunities for long-term growth. Hence, buying into them could secure the future of any investor looking for a stock adequate for a “buy and hold.” But the key is not just in buying stock. It is important to buy the right ones. A smart way to go about this is to monitor company performance and industry trends, as well as diversify across different players within AI (from hardware to software and services). Another good trick is balancing established leaders like Amazon and Alphabet with emerging players. Despite the dips that may come along the way, doing due diligence before investing and then patiently waiting will surely give you your favorite financial growth story of the next decade.
