IonQ has taken an early lead in quantum computing accuracy.
SoundHound is looking to be an agentic AI leader.
If you're looking for some stocks that have the potential to turn a small investment into a lot of money, you're going to have to take some risks. These stocks aren't going to be the cornerstone of your portfolio given their speculative nature, but if one of them hits, they could be a millionaire maker. Let's look at two stocks with that type of potential.
Technology is evolving quickly, and the next big innovation after artificial intelligence (AI) could be here quicker than many think. While AI is changing the landscape we live in, quantum computing has the potential to take us to new heights by being able to rapidly solve problems and unlock secrets that would take classical supercomputers a millennium to unravel.
Will AI create the world's first trillionaire? Our team just released a report on the one little-known company, called an "Indispensable Monopoly" providing the critical technology Nvidia and Intel both need. Continue »
The biggest issue currently facing the technology is that it is error-prone, as the quantum bits, or qubits, behind the technology are very sensitive to outside forces such as temperature and vibrations. One company leading the way with accuracy, though, is IonQ (NYSE: IONQ). The company has achieved 99.99% two-qubit gate fidelity, making it a leader in accuracy and reaching a point where it can apply quantum error correction techniques in its efforts to develop a fault-tolerant quantum computer.
IonQ's accuracy leadership comes from its trapped ion method, which uses actual atoms, which by nature are identical and more stable than the fabricated qubits used by competitors. With its acquisition of Oxford Ionics, it was then able to replace clunky, less stable lasers with electronic qubit control (ECQ) that uses microwave electronics integrated directly into its chips. This also helps shrink the size of its machines and helps make it less temperature sensitive, as lasers produce heat.
At the same time, IonQ is looking to take a page out of Nvidia's playbook with the goal of controlling the entire quantum ecosystem. As such, it has been an aggressive acquirer in the space, looking to gain new adjacent technologies like quantum networking and quantum sensing. More recently, IonQ agreed to purchase quantum foundry SkyWater, which will vertically integrate the company and allow it to manufacture its own quantum chips. This should help speed up prototyping and eventually allow it to scale more quickly.
IonQ is a speculative stock in a nascent industry, but if it can crack the quantum code, the stock has huge upside potential.

Before we get to quantum computers, we'll be entering the next phase of AI with agentic AI. One of the more intriguing stocks in this area is SoundHound AI (NASDAQ: SOUN). It started out as an AI voice company whose "speech-to-meaning" and "deep meaning understanding" technology can help voice assistants interact with people in a more conversational and natural manner. It is now applying its AI voice technology to AI agents.
The company made this strategic shift when it acquired Amelia, which provides the virtual agents you may come across when you call a customer service line. Amelia also brought SoundHound a long list of customers in regulated industries like healthcare and financial services that have compliance requirements and their own jargon. SoundHound has now taken its voice technology and combined it with Amelia's virtual agents to help create customer-focused AI agents that can better interact with customers and understand their intent with its Amelia 7 platform.
The company has already been growing quickly, and it is now starting to see strong traction with its agentic AI solution. As Amelia's customer renewals come up, it is seeing higher prices and larger volume commitment. Its core automobile and restaurant customers continue to grow nicely. The company nearly doubled its revenue in 2025 and has projected revenue to grow between 33% and 54% this year.
If SoundHound can become the premier agentic AI customer service solution, the stock has a lot of potential upside from here.
