I always thought Who Wants to Be a Millionaire? was a silly name for a game show. Of course everyone who isn't already a millionaire (or billionaire) wants to be one!
The good news is, the stock market has made far more people into millionaires than the TV game show, and right now, AI stocks are outperforming the broader market.
Here are three AI stocks that have serious millionaire-maker potential, and you don't even have to phone a friend to ask for the answers.
1. Nvidia

Yes, it already has a $5 trillion market cap. Yes, it's already up more than 1,250% in the past five years. But the thing about winners is that they tend to keep on winning unless something comes along to dislodge them from their perch. And right now, when it comes to AI processors, Nvidia (NVDA 3.58%) is the undisputed leader in the industry. No other company has even come close to mounting a serious challenge.
Normally, once a company reaches megacap size, its growth tends to plateau. But you'd never know that from Nvidia's recently released fiscal 2027 Q1 financials. Revenue was up 85% from the year-ago quarter, and non-GAAP net income grew by a jaw-dropping 139%, with further growth expected. That's the kind of growth that tiny tech start-ups dream of. In spite of all that, the stock is down 6% from its highs, giving Nvidia serious millionaire-making potential from here.
2. Alphabet
Alphabet (GOOGL 0.69%) (GOOG 0.76%) isn't so much an AI company as an everything company, but its AI bona fides go back to 2016, when its AlphaGo AI defeated a top-ranked player at the Chinese board game Go, a feat considered more impressive than Deep Blue's 1997 chess victory over international grandmaster Garry Kasparov.
Since then, Alphabet has rolled out a number of AI-focused improvements across its ecosystem, including the Google Gemini AI chatbot, AI-powered Google Search, and its Waymo self-driving car initiative.
A few years ago, many onlookers believed that Alphabet's core Google Search business would be hurt by diminishing ad revenue as AI chatbots grew in popularity, but the company has overcome those concerns. Instead, thanks to its moves to enhance Google Search with AI features, that business has continued to thrive, with ad revenue climbing 19% to $60.4 billion in Q1 2026 alone. Meanwhile, Google Cloud revenue increased 63% to $20 billion, largely due to growth in enterprise AI solutions and AI infrastructure.
As one of the largest companies in the world, with a market capitalization of $4.7 trillion, Alphabet, like Nvidia, might seem too big to be a growth stock, but it continues to assert itself as a dominant force in the AI world. Alphabet's stock should continue to produce market-crushing returns worthy of a millionaire-maker portfolio.

3. SoundHound AI
To explain why AI voice chat specialist SoundHound AI (SOUN 8.22%) could make you a millionaire, we need to revisit the story of AlphaGo's victory at the board game Go.
Go's 19x19 board is much larger than chess's 8x8 board, and it has an exponentially higher number of possible moves, which is why it took almost 20 years longer for an AI to beat a top-ranked human player at Go than at chess.
To win at chess, Deep Blue -- after executing some preprogrammed opening moves -- compared every possible series of moves and selected the path with the best probability of winning. But the number of possible Go moves is too high for even an advanced AI to compare them all, so AlphaGo didn't even try. Instead, AlphaGo played tens of millions of games against itself, and it drew on the outcomes of those games to make its decisions.
Any customer service interaction has infinitely more possibilities than a game of Go. All those possibilities make it very difficult to train an AI customer service agent to human-level capability. But SoundHound AI is taking a leaf out of AlphaGo's playbook. It has just released a new agentic AI platform called OASYS, which not only deploys AI agents to perform specific tasks, but also coordinates multiple agents, evaluates them, and automatically improves those agents based on their past interactions. It's the equivalent of AlphaGo training itself to become more efficient.
SoundHound AI is still struggling to achieve consistent profitability, and its stock is 66% off its high.

But its revenue keeps growing, and it seems to be successfully making inroads into industries beyond its core restaurant and automotive customers. If SoundHound's OASYS AI agents can beat larger AI companies to the punch in delivering human-level customer service interactions, it could easily become a millionaire-maker stock.
