Top 10 AI Stocks Under $20 (What to Know Before You Buy)

What’s a better deal: buying one share of a $500 stock or 25 shares of a $20 stock? If you think they’re the same, you’re not alone—but it’s one of the biggest myths in investing. As artificial intelligence continues to change our world, understanding this difference is key to safely navigating the exciting world of affordable AI stocks.

Think of it like pizza. If one pie is cut into four $10 slices and another into twenty $2 slices, you can’t know which is pricier without knowing the total cost of each pizza. Stocks work the same way. The true value isn’t the share price but the price of the whole company, a concept called market capitalization.

For example, a company with a $5 stock but a billion shares has a $5 billion market cap. Another with a $20 stock but only 100 million shares has a $2 billion market cap. The company with the cheaper stock is actually more than twice as “expensive.” This concept is your starting point. Before looking at a stock’s price, your first step should be to Google “[Company Name] Market Cap.” It tells you far more than the price tag ever will.

Beyond the Buzzwords: How to Spot a True “AI Company”

With “AI” as the market’s hottest buzzword, many companies are “AI-washing”—using AI tools to improve their business without being a true AI company at their core.

The easiest way to cut through the hype is to ask one simple question: If you took their unique AI away, would the business still have a product to sell? A pizza chain might use AI to optimize delivery routes, but its product is still pizza. Take the AI away, and they still sell pizza.

In contrast, a company whose main product is the AI—like software that analyzes medical scans to find diseases—would have nothing left to sell. This distinction is crucial because a true AI company’s success is directly tied to its technology, offering a more focused (and often riskier) investment. The companies on our list fall primarily into this second category.

3 Well-Known AI Contenders Around $20

The first three companies on our list are frequently discussed as affordable AI stocks, but their popularity also means prices can swing wildly based on news and investor sentiment. The goal is to understand the business behind the ticker, including its significant risks.

• Palantir (PLTR)

  • What It Does: Helps governments and massive corporations make sense of huge, messy datasets.
  • The AI Angle: Its software acts like a detective, using AI to find hidden connections and patterns in data that a human would miss, from tracking supply chains to identifying security threats.
  • The Big Risk: A large portion of its revenue comes from a few major government contracts, which can make its future growth less predictable.

• C3.ai (AI)

  • What It Does: Sells a platform that helps other businesses build their own custom AI applications.
  • The AI Angle: Think of it like a Lego set for AI. C3.ai provides the building blocks so companies can create AI tools tailored to their specific needs, like predicting equipment failure.
  • The Big Risk: It operates in an extremely crowded space, facing intense competition from tech giants like Microsoft and Google.

• SoundHound AI (SOUN)

  • What It Does: Builds advanced voice AI that can understand complex, conversational human speech.
  • The AI Angle: This is the technology behind the voice assistants in some cars and restaurant drive-thrus that let you speak naturally without using robotic commands.
  • The Big Risk: It’s a small company competing directly against the voice AI divisions of behemoths like Amazon (Alexa), Apple (Siri), and Google.

These companies are tackling huge problems with ambitious technology. But ambition often comes with fierce competition and major hurdles. While these are some of the most talked-about names, other high-potential AI stocks are quietly working in more specialized fields.

4 More AI Stocks in Specialized Fields

Beyond the well-known contenders, some of the most fascinating AI work is happening quietly. Smaller companies are using artificial intelligence to solve specific problems in industries like healthcare, security, and enterprise software. They aren’t trying to be the next Google; they’re aiming to be indispensable in one particular field.

In medicine, some small-cap companies use AI to analyze biological data, hoping to discover new drugs or diagnostic tools faster and cheaper. Their potential is enormous, but so is the risk, as success often depends on navigating years of expensive clinical trials and strict FDA approvals.

Similarly, other niche players apply AI to public safety and cybersecurity, but they often face a long process of convincing large organizations to adopt their new technology. This highlights a crucial lesson: a specialized focus can be a shield against competition, but it also means the company’s fate is tightly linked to the health of its chosen industry.

The AI ‘Gold Rush’: Finding “Shovel” Stocks Besides Nvidia

During the 1800s gold rush, the people who consistently got rich weren’t the miners but the merchants selling them picks and shovels. In today’s AI boom, this strategy focuses on companies providing the essential gear every AI developer needs.

While giant chipmakers like Nvidia create the powerful “brains” for AI, a complete system is much more complex. It also requires incredibly fast memory to hold data and high-speed networking components to let all the parts communicate without delay. Without these supporting pieces, even the most powerful AI chip is useless.

This is where you might find companies that build crucial supporting hardware, such as specialists in memory controllers or optical components for data centers. By investing in these suppliers, you are betting on the growth of the entire AI ecosystem rather than a single company’s success. However, just because a company is selling shovels doesn’t make it a guaranteed win.

Why ‘Cheap’ Stocks Can Be a Trap: 3 Risks You Can’t Ignore

Finding a promising company with a stock price under $20 can feel like uncovering a hidden gem, but these “bargains” can often be traps. Low-cost stocks carry magnified risks compared to established giants.

Specifically, there are three major dangers to be aware of:

• Volatility: A small bit of news—or even just a rumor—can send a low-priced stock soaring or crashing in a single day, making it more like a lottery ticket than an investment.

• Intense Competition: A small AI firm with a brilliant idea is often up against giants like Google or Microsoft, who can spend billions to create a similar product and muscle the smaller company out of the market.

• Delisting Risk: If a stock’s price stays too low (often under $1) for too long, major exchanges can remove it. This “delisting” makes your shares incredibly difficult to sell, potentially trapping your money.

This isn’t to say all small companies fail, but it highlights the danger of betting everything on a single, unproven player.

Don’t Want to Pick Winners? Buy the Entire AI Team at Once

Instead of trying to pick one winning company, you can bet on the whole team. That’s the idea behind an Exchange-Traded Fund (ETF). An ETF is a single stock that holds small pieces of many different companies focused on a theme like artificial intelligence.

This strategy, called diversification, is your best defense against risk. Since you own a little of many companies, one firm’s failure won’t sink your investment, as the success of others helps balance out the losses. It cushions you from the wild swings we discussed earlier.

Funds like the Global X Robotics & Artificial Intelligence ETF (BOTZ) do exactly this. While even ETFs carry their own risks, they provide a powerful alternative to picking individual stocks.

Your Next Move: How to Build an AI Watchlist

A $20 stock price is no longer just a simple bargain to you. Now you understand that a company’s total value—its market cap—matters far more. You’ve shifted from hunting for “cheap” stocks to evaluating potential value.

To build a smart watchlist, take these simple first steps:

1. Pick three companies from our list that genuinely intrigued you.
2. Look up their market cap and read their “What We Do” page.
3. Add them to a free watchlist—and just observe. See how they move.

By turning curiosity into cautious research, you’ve already taken the most critical step in your investing journey. You’re no longer just chasing low prices; you’re learning how to evaluate AI companies and building the confidence to make smarter decisions in the future.
