The White House has put a 2028 milestone on quantum computing, but investors may need to watch cash runway as closely as technology.
Quantum computing has spent years sitting in the “future technology” bucket.
Investors have heard the promises. Faster drug discovery. Better logistics. New breakthroughs in materials science. Powerful simulations that today’s computers cannot handle efficiently. But for most of the market, quantum computing has still felt like a long-term science project.
That may be changing.
A recent executive action called for accelerating U.S. quantum computing development and set a 2028 target for a scientific-grade quantum computing system capable of enabling quantum-enabled scientific discovery and research.
Whether that deadline proves realistic is not the only question investors should be asking. The bigger takeaway is that quantum computing is increasingly being treated as strategic infrastructure. It is tied to national competitiveness, economic leadership, scientific progress, and security priorities.
That changes the investment conversation.
The quantum race is no longer just about who has the most promising technology. It is also about who has the balance sheet to survive long enough to reach the finish line.
The Real Risk in Quantum Stocks
When investors talk about quantum stocks, the conversation usually centers on qubits, architectures, partnerships, and technical roadmaps.
Those things matter. But there is another factor that may matter just as much between now and 2028: dilution.
Many publicly traded quantum companies remain unprofitable. They are still spending heavily on research, hardware development, commercialization, and infrastructure. Since many do not generate enough cash internally, they often need outside capital to keep going.
That usually means issuing more shares.
For shareholders, that can be a problem. When a company issues new stock, existing investors own a smaller percentage of the business. In an emerging industry like quantum computing, dilution can slowly eat away at returns even if the underlying technology continues to improve.
That is why I am looking at these companies through what I call a Dilution Score.
This is not an official Wall Street metric. It is a simple framework for comparing financing risk across quantum companies.
The score is based on three factors:
- Historical dilution
- Capital intensity
- Dependence on external funding
The goal is to estimate how likely each company may be to rely on future share issuance between now and 2028.
Here is the basic framework:
- Low: Strong financial flexibility.
- Medium: Some dilution risk, but not necessarily an immediate survival concern.
- High: Greater dependence on external funding.
- Critical: Future dilution could become a major issue for shareholder returns.
Using that framework, let’s look at five quantum stocks investors are talking about most.
IonQ: A Better-Positioned Pure Play
IonQ is one of the most visible names in quantum computing.
The company’s main differentiator is its trapped-ion architecture. Instead of using superconducting circuits like many competitors, IonQ uses electromagnetically confined ions as qubits.
Supporters believe this approach could offer advantages in scalability and system performance as quantum computers become larger and more useful.
From a dilution perspective, IonQ receives a Medium Dilution Score.
That does not mean there is no risk. IonQ is still an early-stage company, and future capital raises remain possible. If management chooses to accelerate research, expand infrastructure, or pursue acquisitions, shareholders could still face dilution.
But compared with many pure-play quantum peers, IonQ appears to be in a stronger position.
The issue is not immediate survival. The bigger question is how much shareholder dilution may occur before the company reaches meaningful commercial scale.
That distinction matters in a 2028 framework.
If quantum computing reaches a major inflection point over the next few years, IonQ’s advantage may be financial flexibility. The company does not appear to be under the same immediate pressure as some peers that may need capital simply to keep funding operations.
Some investors have also raised concerns about insider selling. That can weigh on sentiment, but the larger question is whether the company has enough capital to keep executing its roadmap.
For now, IonQ looks like one of the stronger pure-play quantum names in the survival race.
Investor takeaway: IonQ still carries dilution risk, but its financial position appears stronger than many smaller quantum peers.
D-Wave: Practical Applications, Higher Financing Risk
D-Wave is a very different type of quantum company.
Rather than pursuing universal quantum computing, D-Wave focuses on quantum annealing. This approach is designed for optimization problems such as logistics, scheduling, and resource allocation.
That gives D-Wave an interesting edge. It has been able to build real-world commercial applications earlier than some competitors that are still focused on longer-term universal quantum systems.
But from a dilution perspective, D-Wave receives a High Dilution Score.
The company has repeatedly relied on equity markets to fund operations and growth. That creates a meaningful risk for shareholders unless commercial adoption grows quickly enough to reduce the need for outside financing.
This makes D-Wave one of the more complicated quantum investment stories.
On one hand, the company may have practical applications that many competitors lack. On the other hand, shareholders need to ask whether those applications can turn into enough revenue fast enough to support the business.
The technology may be valuable. But if the company keeps issuing shares to fund its growth, shareholders may not capture as much upside as they expect.
Government support could help. Public-sector funding tied to quantum development may reduce some pressure if more contracts or funding opportunities materialize.
Still, D-Wave needs to prove that practical use cases can translate into a more sustainable financial model.
Investor takeaway: D-Wave may have real commercial relevance, but dilution remains a major risk unless adoption scales quickly.
Rigetti: Big Potential, Critical Dilution Risk
Rigetti is another quantum stock that has attracted attention.
The company focuses on superconducting quantum processors and hybrid quantum-classical computing systems. Its approach is based on the idea that quantum and classical computers will likely work together for years before fully fault-tolerant quantum systems become practical.
If that vision proves correct, Rigetti could play an important role in the broader quantum ecosystem.
Supporters often point to partnerships and collaborations tied to high-performance computing as evidence that quantum and classical systems may become more integrated over time.
But from a financing perspective, Rigetti receives a Critical Dilution Score.
The company has historically expanded its share count significantly to fund research, hardware development, fabrication, and scaling efforts.
This is where the 2028 survival-race framework becomes especially important.
Quantum development is expensive. Timelines can stretch. Commercial contracts may arrive later than expected. If meaningful revenue or large-scale deployments do not come soon enough, Rigetti may remain heavily dependent on external capital.
That could mean more dilution for shareholders.
To be clear, this does not mean Rigetti lacks upside. If the company’s technology gains traction, the stock could have significant potential.
But investors need to separate technology potential from shareholder outcomes.
A company can succeed technologically while still producing disappointing returns if dilution becomes too severe. Rigetti may be one of the clearest examples of that risk.
Investor takeaway: Rigetti may offer upside, but its financing risk is among the highest in this group.
Quantum Computing Inc.: A More Capital-Efficient Model?
Quantum Computing Inc. is pursuing a different path.
The company is focused on photonics-based technologies and software-oriented quantum solutions. Instead of competing only through complex hardware systems, it is trying to build a more accessible and potentially capital-efficient model.
That is part of why the company has attracted interest from retail investors.
The story is relatively easy to understand. Quantum Computing Inc. is trying to pursue quantum solutions without the same infrastructure burden that can come with large-scale cryogenic hardware systems.
From a dilution perspective, Quantum Computing Inc. receives a Medium Dilution Score.
The company still depends on external financing. That risk has not disappeared. But its photonics-focused approach may require less infrastructure investment than some hardware-heavy rivals.
That could matter.
If the company can commercialize its technology without massive capital spending, it may have a more manageable path to funding growth. Lower capital requirements could mean lower dilution pressure over time.
But this remains a big “if.”
Until the company turns its technology into meaningful revenue and customer adoption, investors still face financing risk. The investment case is not just about whether the technology sounds promising. It is about whether the company can commercialize that technology without leaning too heavily on new share issuance.
Investor takeaway: Quantum Computing Inc. may have a more capital-efficient story, but it still needs to prove commercial traction.
IBM: The Quantum Stock With the Longest Runway
IBM belongs in a different category from the other companies on this list.
It is not a pure-play quantum startup. It is a large enterprise technology company with substantial revenue, operating cash flow, and an established customer base.
That changes everything.
Quantum computing is an important initiative for IBM, but it is not the company’s only path to survival. IBM can fund quantum development through its existing business rather than relying on constant equity issuance.
From a dilution perspective, IBM receives a Low Dilution Score.
That gives IBM a major advantage in the 2028 survival race.
While smaller quantum companies must balance technology development with shareholder dilution, IBM can focus more directly on execution. It can continue investing in superconducting systems, cloud integration, enterprise software, and ecosystem development without the same financing pressure facing many pure-play competitors.
The tradeoff is obvious.
IBM may not offer the same explosive upside as smaller quantum stocks. Investors looking for a high-risk, high-reward pure play may find IBM less exciting.
But IBM offers something that may be just as valuable in a long development race: staying power.
If quantum computing becomes a major industry, IBM appears well positioned to participate without needing to bet the entire company on one technology.
Investor takeaway: IBM may not be the most explosive quantum stock, but it appears to have the strongest financial runway.
What the 2028 Survival Race Tells Investors
The quantum race is usually framed as a technology race.
Who has the best architecture? Who can scale qubits? Who can reach useful quantum advantage? Who will land the biggest partnerships?
Those questions matter. But for investors, the road to 2028 may be determined just as much by financing as by engineering.
A company can have promising technology and still hurt shareholders if dilution becomes excessive. Another company may move slower technologically but still create more durable value if it can fund progress without repeatedly issuing large amounts of stock.
Viewed through that lens, the divide becomes clear.
IBM appears to have the longest runway. IonQ looks better positioned than many pure-play peers. Quantum Computing Inc. sits in the middle, with a potentially more capital-efficient model but a lot left to prove. D-Wave and Rigetti face greater pressure to turn technology progress into financial sustainability.
That does not mean one company is guaranteed to win.
Quantum computing remains highly uncertain. The path to 2028 will likely depend on technical milestones, government contracts, commercial partnerships, licensing decisions, and future financing events.
But the key lesson is simple.
Investors should not only ask which quantum company has the most exciting technology. They should ask which company can survive long enough to benefit from it.
Final Thoughts
The 2028 quantum milestone gives investors a useful way to think about the sector.
This is not just a race to build better quantum computers. It is a race to fund development, preserve shareholder value, and reach commercial scale without giving away too much ownership along the way.
That is why cash runway matters.
For some investors, a milestone-based approach may be more sensible than buying all at once. Instead of assuming every quantum stock will reach the finish line, investors can watch for measurable progress.
That includes revenue growth, customer adoption, government contracts, commercial deployments, balance sheet strength, and share count discipline.
Quantum computing could still become one of the most important technology markets of the next decade. But in this race, the winner for investors may not be the company with the loudest story.
It may be the company that can still afford to compete in 2028.
