Investors looking to capitalize on the ongoing trends in artificial intelligence (AI) can expect significant benefits for years to come. Despite being only in the fourth year of a major AI investment surge, projections indicate that this momentum is poised to last well into the latter part of the decade, potentially until 2030 and beyond.
Currently, the AI landscape remains in its early stages, with much room for growth and integration into various sectors of work and daily life. As such, certain stocks positioned to leverage the advancements in AI technology could yield substantial returns for investors. Here are four AI stocks identified as promising buy-and-hold investments for the long term:
Alphabet (GOOG, GOOGL) has exceeded many expectations in 2025, even outperforming smaller competitors in the generative AI space. The launch of its generative AI model, Gemini, has been successfully integrated into Google’s search engine, resulting in generative AI-powered summaries appearing at the top of search results. This innovation has reinforced Google’s dominance in the search engine market. In addition to its successful AI integration, Alphabet’s cloud computing division is thriving, providing crucial infrastructure for other companies aiming to develop AI solutions. The company’s current market cap is approximately $4.1 trillion, with a stable gross margin of 59.18%.
Nvidia (NVDA), widely recognized for its graphics processing units (GPUs), remains a critical player in the AI industry. While there are concerns that its dominance may fade as AI computing infrastructure matures, the nature of GPUs suggests otherwise. Given their relatively short life span, GPUs will need regular replacement, thus creating a recurring revenue stream for Nvidia. The company currently has a market cap of around $4.5 trillion and boasts a gross margin of 70.05%. As the computing market continues to expand, Nvidia presents a strong investment opportunity.
Taiwan Semiconductor Manufacturing (TSM) is integral to AI capabilities, producing the chips that power most AI workloads across diverse devices. TSMC is expected to launch a new 2nm chip in 2026, which promises to be more energy-efficient than its predecessor, consuming 25% to 30% less power. The demand for advanced and efficient AI chip technology will persist, ensuring TSMC’s relevance and growth in the market. The company’s trajectory positions it as a strong buy-and-hold option.
Microsoft (MSFT) has charted a different path in the AI landscape. Instead of relying solely on in-house generative AI models, Microsoft has partnered with industry leaders such as OpenAI and others, enriching its cloud platform, Azure. This strategic move has contributed to Microsoft’s impressive growth in recent years. The company is actively integrating AI tools into its robust suite of business applications, further embedding itself in daily business operations across the globe. Microsoft’s current market valuation stands at about $3.4 trillion, with a gross margin of 68.76%.
All four of these companies not only represent excellent long-term investments but are also positioned for immediate growth. Each is projected to surpass the performance of the S&P 500 in the coming years, making them a central piece of any comprehensive AI-focused investment portfolio.
