3 Top Tech Stocks That Could Make You a Millionaire

It takes a lot of time and some smart decisions to build a retirement portfolio of $1 million or more. But it's important because many bills keep coming in, even when you're done with your career.

Financial planners often suggest that you should be ready to live on roughly 80% of your pre-retirement income if you want to have the same lifestyle. For many people, that means having more than $1 million in their 401(k) plans or individual retirement accounts (IRAs) before heading off into the sunset.

Investing in the stock market remains one of the best ways to help you reach your retirement goals, particularly as you capitalize on the power of compounding to keep your portfolio growing over a period of years. And while building a well-rounded portfolio is always ideal, I also have some favorite tech stocks that I believe can help you reach your $1 million goal.

1. Broadcom

Nvidia and, to a lesser extent, Advanced Micro Devices get most of the attention among semiconductor stocks. But Broadcom (NASDAQ: AVGO) shouldn't be overlooked. The company has significant contracts with Alphabet and Anthropic and is seeing massive gains in revenue and income.

Rather than being known for graphics processing units, Broadcom designs application-specific integrated circuits (ASICs) that are customized for clients to handle the workloads they require. That means that Broadcom's ASICs can be an efficient and attractive alternative to Nvidia GPUs.

Broadcom also stands to benefit from Alphabet's stated plans to spend $185 billion in capital expenses related to AI. Broadcom works with Alphabet to make the company's Tensor Processing Units (TPUs), which are Alphabet's in-house solution to GPUs.

Fourth-quarter revenue (for the quarter ended Nov. 2, 2025) was $18.01 billion, up 28% from a year ago. Net income was $8.51 billion, an increase of 97% from the previous year. Much of the gain was attributed to artificial intelligence (AI) semiconductor revenue, which Broadcom said rose 74% year over year.

2. Sandisk

Sandisk (NASDAQ: SNDK) may be flying under the radar as well, but that's mostly because the company reemerged a separate entity just a year ago.

Western Digital bought Sandisk in 2016 in a deal that combined Western Digital's hard drive business with Sandisk's flash memory business. However, Western Digital spun Sandisk off again in February 2025. The new-look company keeps Western Digital and Sandisk's flash products, as well as USB drives, memory cards, and solid-state drives (SSDs). Western Digital continues to focus on hard disk drives.

Today, Sandisk operates in three segments: data center, edge computing, and consumer products. And while the edge segment generates the majority of revenue, the data center segment is growing fast -- up 64% in the second quarter of fiscal 2026. Overall, Sandisk's revenue was $3.02 billion in the quarter, an increase of 61%, and its net income of $803 million was a huge 672% jump from last year.

Sandisk's potential is impossible to ignore right now.

3. Nebius Group

Nebius Group (NASDAQ: NBIS), the Dutch data center company, may be my favorite stock right now. Nebius has an interesting history. It was formerly called Yandex, a Russian internet company that operated the country's dominant search engine.

But after Moscow invaded Ukraine and Russian companies were hit by sanctions, the Nasdaq suspended trading of Yandex stock. The company shed its Russian assets, rebranded as Nebius and emerged as a tech company that provides full-stack AI infrastructure.

Now the company is seeing massive gains as both hyperscalers and developers seek computing capacity to train and run AI platforms. Nebius reported revenue in the fourth quarter of $227.7 million, up 547% from a year ago. The company is seeing steep losses, recording $173 million as an adjusted net loss in the quarter as it invests in AI infrastructure. But it's betting those investments will pay off down the road.

In fact, Nebius reported $1.25 billion in annual run rate (ARR) in 2025, beating its own guidance. And it's projecting ARR of between $7 billion and $9 billion for 2026, a gain of more than 7 times.

Nebius may not be for every investor, but I love the company's potential. As it rapidly grows, it has millionaire-maker stock potential.
