3 Top Quantum Computing Stocks to Buy in 2026
Summarize this article with:
It's still early, but quantum computing appears to be another significant leap forward in technological innovation. Quantum computers utilize the laws of physics to perform complex calculations exponentially faster than even today's supercomputers can. Researchers at McKinsey & Company anticipate that quantum computing can grow to a $100 billion market over the next decade, and who knows where it will go from there. Investors have poured into several pure-play quantum computing stocks, but companies like IonQ and D-Wave Quantum currently generate little revenue and have already risen to sky-high valuations. However, investing in quantum computing doesn't need to be an all-or-nothing gamble. Here are three companies with established and successful businesses that also deal in quantum computing. Consider buying them as top quantum computing stocks for 2026. Image source: Nvidia 1. Nvidia The explosive growth in artificial intelligence (AI) has rocketed Nvidia (NVDA 0.35%) to the top of the technology world as the leader in GPU chips used in data centers for AI workloads. Quantum computing could become a key stepping stone to more advanced AI over the coming years as computing power demands continue to increase.Advertisement Nvidia wouldn't want to be on the outside of quantum computing if it began displacing traditional GPUs, so the company has a clear interest in exploring quantum technology. It has developed NVQLink, which enables quantum processors to work with AI supercomputers, as well as CUDA-Q, an open-source development platform for quantum systems and applications.

Nvidia's dominance in the GPU space gives it a strong positioning to achieve that. The company's core data center business remains strong, with a $500 billion order backlog that is likely to lead to another banner growth year in 2026. 2.
International Business Machines (IBM) Some view International Business Machines (IBM +2.54%) as a tech dinosaur. The company has been around for decades and has struggled at times to adapt to industrywide changes. To its credit, IBM has steadily divested old assets and made strategic acquisitions to remake itself as a leading provider of hybrid cloud computing, AI software, and consulting services to enterprise customers. Simply put, corporations turn to IBM for help in integrating new technology into their businesses, and IBM provides them with advice and any necessary products and services. IBM is also a leading pioneer in quantum computing. It has developed quantum processors and full computers, as well as Qiskit, which it claims is the most widely used software development kit for quantum computing.

To date, IBM has generated over $1 billion in lifetime revenue related to quantum computing. IBM probably won't generate explosive growth. Still, it's a steady and reliable stock for those seeking exposure to quantum computing with lower risk. 3. Microsoft It shouldn't come as a surprise to see Microsoft (MSFT +1.20%) on this list. The $3.5 trillion tech behemoth has its nose in just about every tech trend out there. Microsoft has a strong foothold with corporate customers through its Microsoft 365 and Dynamics 365 software, as well as its Azure cloud services platform. It's also a clear pathway to introduce new products and services, which could eventually include quantum computing. Currently, Microsoft's quantum efforts reside at the research level. Early last year, it announced it had developed a quantum chip, the Majorana 1, capable of fitting 1 million qubits on a single chip -- far more than current quantum computers have. Remarkably, Microsoft achieved a new state of matter to build this chip. Its topological core is neither a solid, a liquid, nor a gas, but a new state of matter.

If quantum computing takes off, Microsoft will undoubtedly be a competitor. For now, investors can continue to enjoy the strong growth across Microsoft's various businesses. As arguably the world's leading technology company, Microsoft is a no-brainer to include in this list.
