If you're looking to become a millionaire, artificial intelligence (AI) stocks are a great way to get there. With hundreds of billions of dollars being spent on the AI buildout this year alone, I think there's an incredible investing opportunity in both chipmakers and AI infrastructure.
Nvidia is my ride-or-die AI stock. But if you're looking for an alternative to Jensen Huang's juggernaut, here are three great choices that can help push your portfolio to that million-dollar threshold. And each of them occupies a different area of the AI space.

1. Broadcom
Broadcom (AVGO 1.63%) is a competitor of Nvidia, operating in a different lane but hoping for the same result. Nvidia's entry in the AI chip field is its powerful graphics processing units (GPUs), which are flexible enough to handle a variety of AI tasks. It's what makes them popular, but also extremely expensive -- its Blackwell GPUs cost about $30,000 each, and hyperscalers bundle them by the hundreds so they can do complex AI tasks.
Broadcom's answer is its application-specific integrated circuits (ASICs), which are custom-made to handle the specific workloads of its clients. That means they aren't as powerful as Nvidia chips, but they're also less expensive because they don't have all the bells and whistles of GPUs -- they just have what the customer needs to train and run their AI programs.

That approach is allowing Broadcom to build its roster of AI chip customers. It has been working with Alphabet to create that company's Tensor Processing Units (TPUs), which are Alphabet's in-house alternative to GPUs. Alphabet is now reportedly marketing its TPUs to sell to other companies.
Broadcom has a mammoth $21 billion deal with Anthropic, the AI company that created the Claude large language model, to supply it with nearly 1 million AI chips. Broadcom also has a deal with OpenAI, the maker of ChatGPT, to supply 10 gigawatts worth of custom chips.
2. Lam Research
Lam Research (LRCX 4.31%) is a true pick-and-shovel AI stock. This California company supplies components to foundries that manufacture semiconductor chips, including microprocessors and memory devices. The company develops wafer-processing capabilities that foundries need to fabricate transistors, advanced memory, sensors, and more on chips.
Revenue in the fourth quarter of 2025 was $5.34 billion, up from $4.37 billion a year ago. Net income was $1.59 billion, good for $1.26 per share.

"Entering 2026, our expanding product and services portfolio is enabling the market's transition to smaller, more complex three-dimensional devices and packages," CEO Tim Archer said. "With AI accelerating, we are ramping execution velocity across the company to support our customers' growth and realize our vision for multi-year outperformance."
3. Taiwan Semiconductor Manufacturing
Lam supplies the equipment that foundries need, but if you want to invest in a foundry itself, the best choice is Taiwan Semiconductor Manufacturing (TSM 4.96%). The company, better known as TSMC, is the biggest foundry in the world and counts Nvidia, Broadcom, and Apple as major customers.
TSMC's processes are highly valued by chipmakers because it specializes in making the most advanced chips with the smallest possible transistors. Sixty percent of its revenue in 2025 came from manufacturing 3-nanometer and 5-nm chips, the company said, up from 52% a year ago.
And that expertise means that TSMC's profits and revenue are on the rise. Net revenue was $122.4 billion in 2025, up 35.9% from a year ago. TSMC was able to run with an operating margin of nearly 51%.

Why this grouping works
Nvidia unquestionably dominates the AI space and all the headlines. But AI growth benefits multiple players. Investors should take advantage of that.
Through Broadcom's customized solutions, Lam Research's components, and TSMC to put it all together, these three companies serve as a small portfolio of AI stocks that offer diversification and stability for your quest to build a million-dollar portfolio.
