3 Best Artificial Intelligence (AI) Stocks to Buy in January

One of the biggest themes in the stock market in 2024 Artificial Intelligence (AI)Which is showing signs of becoming a new technology. That said, AI still appears to be in its infancy, with 2025 still promising plenty of opportunities in the sector.

Let’s look at three AI stocks to buy this month.

nvidia (NASDAQ: NVDA ) Arguably the biggest winner has been from AI, as its revenue has absolutely skyrocketed in the past two years. In the financial year 2024, which ended in January last year, its income increased by 125 percent, while in the financial year 2025, its income has once again more than doubled.

of the company Graphic Processing Units (GPUs) GPUs are the backbone of building AI infrastructure because of their impressive processing speed, which is needed to handle large language model (LLM) training and AI inference. Meanwhile, it has amassed 90% market share in the GPU space compared to rivals Advanced Micro Devices Thanks to its superior software platform CUDA, which includes developer tools and micro-libraries that allow its chips to be easily programmed to handle various AI-related tasks.

Spending on AI infrastructure is only going to continue apace, as training LLMs requires more and more computing power. Meanwhile, Nvidia’s largest customer Microsoft (NASDAQ: MSFT ) announced that it will spend nearly $80 billion on AI data centers this calendar year.

Typically, about half the cost goes to servers with GPUs. By comparison, for its last fiscal year, which ended in June, Microsoft spent $44.5 billion in capital expenditures (capex). Even with other big customers ramping up capex spending on AI infrastructure this year, Nvidia still has a lot of upside.

Despite its strong stock performance, Nvidia trades at a forward price-to-earnings ratio (P/E) of about 31.5 and a price/earnings-to-growth ratio (PEG) of 0.98, based on 2025 analyst estimates. does business A PEG below 1 is generally viewed as undervalued, and growth stocks will often trade with PEGs above 1.

Microsoft is planning to spend big on AI infrastructure this year, and for good reason. The company’s cloud computing unit Azure has been a big AI winner, showing revenue growth of 33% last quarter, while its Azure OpenAI usage has doubled in the past six months. Azure is a consumption model, and customers are using its services to help build their own AI agents and applications. It is also leading to greater use of its data and analytics services.

While Azure is showing strong growth, it could be even stronger if not for capacity constraints. It has already forecast that Azure revenue will pick up in the second half of its fiscal year as more capacity comes in from previous capex spending. Meanwhile, it’s pouring a lot of money into building data centers around the world to try and keep up with demand.
