Artificial intelligence (AI) continues to be one of the hottest investment themes of the decade. From powering search engines and driverless cars to running data centres and financial models, AI is now embedded in nearly every major technology trend.
As investors look for the best AI stocks to buy for 2025, the market remains divided between established giants driving the infrastructure of AI and a new generation of startups redefining how the technology is built, deployed, and scaled.
1. NVIDIA
Among the leading AI stocks to invest in 2025, Nvidia (NASDAQ: NVDA) remains the standout name. Over the last two years, its dominance in AI chips has propelled it to become one of the most valuable companies in the world.
Big Tech firms such as Microsoft, Alphabet, Meta, and Tesla are spending billions on Nvidia’s products to power their AI models, fuelling record demand for its new “Blackwell” chip. Analysts expect Nvidia’s earnings per share to jump 50% year-on-year to $4.43 by early 2026, giving it a forward P/E ratio of around 34 and a PEG ratio of 0.7.
With demand still outstripping supply, the stock could feasibly climb toward $200 this year, although short-term volatility is likely. Nvidia remains one of the best artificial intelligence chip stocks and a cornerstone of any long-term AI portfolio.
2. AMAZON
Amazon (NASDAQ: AMZN) also offers strong exposure to AI growth. In late 2024, it launched Amazon Nova, a suite of AI models designed to help businesses develop and deploy their own generative applications.
At the same time, its new Trainium3 AI chips are being positioned as a cost-efficient alternative to Nvidia’s GPUs, strengthening its presence in the infrastructure market.
Despite solid performance recently, Amazon’s shares still trade near historical valuation lows with a forward P/E of 37, suggesting further upside potential. For investors seeking best AI stocks for 2025 that combine growth and diversification, Amazon remains a compelling option.
3. SNOWFLAKE
Snowflake (NYSE: SNOW) represents a more speculative but exciting opportunity among best AI growth stocks 2025. As a cloud-based data and analytics platform, Snowflake provides the backbone for companies looking to adopt AI. After lifting its 2025 revenue forecast and forming a partnership with Anthropic, the company appears well-placed to benefit from the next wave of AI-driven data demand.
Although its valuation remains high, analysts forecast earnings growth of nearly 40% in 2026, which could justify its premium. For investors willing to take on more risk, Snowflake could be a good artificial intelligence share to buy now.
AI Start Ups
While these major players dominate public markets, a new generation of startups is emerging. According to a recent CMC Invest Compass report, companies such as Nscale, Modular, Cohere, Rebellions, and Groq are redefining AI. UK-based Nscale recently raised $1.1 billion in the largest Series B round in European history to build “neoclouds” that lease AI computing power.
Modular, founded by ex-Apple and Alphabet engineers, is building an open alternative to Nvidia’s CUDA software. Cohere, backed by Nvidia and Salesforce, develops enterprise language models, while Rebellions and Groq are creating next-generation AI chips focused on inference speed and efficiency.
These firms are not yet publicly listed, but they highlight where future opportunities could arise. Together, they show that the next best AI stocks might not come from today’s tech giants but from the challengers reshaping the foundations of artificial intelligence itself.
