When it comes to quantum computing stocks, IonQ is frequently one of the first companies investors consider. Thanks to its trapped ion technology and strong partnerships with leading cloud platforms such as Microsoft Azure, Amazon Web Services (AWS), and Alphabet's Google Cloud Platform (GCP), IonQ has built a dedicated investor base.
In the last year, its share price has skyrocketed by an astonishing 812%, boosting its market value to around $22 billion. Although IonQ continues to attract attention, those searching for the next major opportunity in quantum computing might want to look in a different direction.
This leads us to Quantinuum—a promising contender in the field that recently raised $600 million from a notable group of investors, including Honeywell ( HON -0.25%), JPMorgan Chase, Amgen, Mitsui, and perhaps most significantly, Nvidia ( NVDA -0.82%). Following this funding round, Quantinuum's valuation has reached $10.6 billion.
Let’s take a closer look at why Quantinuum could emerge as a dominant force in the quantum artificial intelligence (AI) sector—and how investors can get involved right now.
Quantum computing’s trillion-dollar promise
The impressive list of Quantinuum’s investors highlights the broad impact of quantum computing. Honeywell brings industrial expertise, JPMorgan represents the financial sector, Amgen points to pharmaceutical innovation, and Nvidia connects accelerated computing with quantum AI. Collectively, these partners show how quantum advancements are influencing nearly every major industry.
The range of potential uses is enormous—covering everything from fraud prevention and risk analysis to logistics, energy optimization, drug development, molecular modeling, AI training, and generative application creation.
Given these transformative possibilities, it’s no wonder that McKinsey & Company estimates quantum computing could add trillions of dollars to the global economy in the years ahead.

How to gain exposure to Quantinuum
Because Quantinuum is still privately held, its shares aren’t available for direct purchase. However, investors can still participate by buying stock in the publicly traded companies that already have ownership stakes in Quantinuum.
This method not only offers indirect access to the growth of quantum computing, but also provides diversification through established blue-chip companies.
By investing in firms such as Nvidia, Amgen, JPMorgan, and Honeywell, shareholders can benefit from a range of industries that are poised to gain as quantum AI transitions from research to real-world applications. In essence, this approach provides a balanced way to profit from the next wave of computing innovation while remaining anchored in some of the most stable and successful companies in the market.
Why quantum AI represents a major opportunity
Artificial intelligence has already revolutionized global computing needs. In just a short span, companies like Nvidia, Broadcom, and Taiwan Semiconductor Manufacturing have joined the elite group of businesses with trillion-dollar market capitalizations. Nvidia’s rapid ascent during the AI boom has even made it the world’s most valuable company.

Now, quantum technology is set to further this digital transformation by addressing challenges that even the most advanced supercomputers struggle with. When combined with AI, quantum computing could deliver breakthroughs in efficiency and transform industries that will shape the next era of technology.
Quantinuum’s achievement of a $10 billion valuation, supported by leading players from various sectors, demonstrates that the move toward quantum applications is not just theoretical—it is already happening.
For those looking to invest, the takeaway is straightforward: You don’t have to wait for Quantinuum to go public to benefit from its growth. By assembling a portfolio of quantum-related blue-chip stocks, you can capture the current momentum of AI while positioning yourself for the long-term gains that quantum computing promises.
