3 AI Stocks That May Be The Biggest Winners In 2026

Artificial intelligence stocks have been some of the best investments over the past year. Many stocks in this industry beat the S&P 500 in 2025, and some of those same stocks are poised to extend their runs into 2026 and beyond. These AI stocks might become some of the biggest winners in 2026.

IREN

IREN (NASDAQ:IREN) is an AI infrastructure company that has AI data centers and gigawatts ready to go. It landed a 5-year, $9.7 billion deal with Microsoft (NASDAQ:MSFT | MSFT Price Prediction) for 200 megawatts. That deal demonstrates how much tech companies will pay for data centers and energy that can fulfill AI workload requirements.

IREN has roughly three gigawatts in its pipeline and has moved quickly in the industry. Its 1.4 gigawatt Sweetwater 1 site should be ready in April, while other competitors are still a few years away from having that much energy online and ready to go.

While the company got started as a crypto miner and still makes most of its revenue from that activity, the Microsoft deal and the capacity to support several deals like it should change IREN’s trajectory. Investors have already noticed, bidding the stock more than 300% higher over the past year, but the AI stock is still in its early innings.

Rezolve AI

If you want to find compelling AI stocks that can crush the stock market, it’s worth going small. Rezolve AI (NASDAQ:RZLV) only has a $1.5 billion market cap after rallying by more than 90% over the past year. The stock is down by about 40% from its all-time highs, but a recent earnings update has investors excited again.

The agentic AI platform exited 2025 with approximately $209 million in annual recurring revenue, and the company told investors it expects to exit 2026 with at least $500 million in annual recurring revenue. The company also expects to earn $350 million in 2026 compared to $40 million in 2025. 

The annual recurring revenue comes from more than 650 enterprise customers, and all of this growth can lead to higher margins. Rezolve also cited strong demand from institutional investors when announcing that it intends to exit 2026 with at least $500 million in recurring annual revenue. 

Aeluma

Aeluma (NASDAQ:ALMU) is a semiconductor company that specializes in high-performance and scalable technologies. The stock has almost tripled over the past year as more investors pour their capital into the emerging company. It’s akin to a venture capital bet, since the company only brought in $1.4 million in Q1 FY26. However, the company won new partnerships and extended contracts with existing clients, including NASA.  

Its technology is positioned to benefit from AI, robotics, mobile, and other industries. Its outsourced wafer fabrication activities increased nearly five-fold, and it’s already contributing to meaningful revenue growth. Aeluma anticipates $4 million to $6 million in revenue in fiscal 2026 as it starts to penetrate commercial markets on a larger scale. 

Aeluma does not have any long-term debt, and its balance sheet also includes $38 million in cash. This growth stock has the potential to generate sizable returns if its commercialization efforts pan out, but it is only suitable for investors who are comfortable with taking big, calculated risks.
