Then examine cash needs, dilution risk, and the assumptions embedded in the share price. Qubit counts alone cannot tell you which company is ahead, and a growing revenue figure does not by itself prove a repeatable business.
Start with what the company builds—and what it has demonstrated
Quantum companies use different architectures and pursue different workloads. Before comparing companies, identify the system type, the commercial product, and the evidence behind management’s claims. A technical milestone can matter, but it is not the same as a customer result or proof of profitable demand.
- Identify the architecture. For example, D-Wave describes superconducting annealing systems as well as a gate-model effort; Rigetti describes a full-stack platform delivered through the cloud; and IonQ’s business includes quantum hardware, cloud access, and related services. These are not interchangeable products, so a single league table based on qubit count can mislead.
- Record the metric in context. Note what was measured, on what workload, under what conditions, and when. Ask whether the result was reported by the company, reproduced independently, or demonstrated by a customer.
- Separate achieved results from targets. Label demonstrated performance, current commercial availability, roadmap milestones, and management projections separately.
- Look beyond qubit count. Gate quality, error rates, connectivity, uptime, error correction, control systems, workload relevance, and scaling constraints all affect whether a system can do useful work.
For company-specific descriptions and risk disclosures, compare the relevant 2025 Form 10-K filings from D-Wave Quantum, Rigetti Computing, and IonQ. ESMA’s May 13, 2026 analysis also identifies technical milestones and projections of economic impact as catalysts associated with share-price movements. Treat such announcements as prompts to investigate the underlying evidence, not as proof that a commercial advantage has been achieved.
Find out how quantum computing companies make money
Read the revenue notes and management discussion in the annual filing, not just the headline growth rate. Separate sales and services tied to quantum systems from development work, government contracts, acquisitions, and adjacent businesses. Check whether revenue is recurring, concentrated among a few customers, conditional on milestones, or dependent on subsidies and partnerships. Compare gross profit and cash collection as well as recognized revenue.
What the 2025 filings show
| Company | Business and reported revenue sources | FY2025 evidence and context |
|---|---|---|
| IonQ | Quantum-system design, development, construction and sales; maintenance and support; quantum-computing-as-a-service access; consulting; and satellite imagery and data. | The listed revenue categories include both quantum-related and adjacent activities. The mix and degree of repeatability should be assessed from the company’s 2025 Form 10-K; no revenue figure is stated here. |
| Rigetti | Development contracts, system sales, and cloud services. | Rigetti said the substantial majority of current revenue came from development contracts and expected them to remain important for several years as it worked to increase system and cloud-service sales. Its 2025 Form 10-K reported net losses of USD 216.2 million for fiscal 2025 and USD 201.0 million for fiscal 2024. |
| D-Wave | Cloud access, professional services, and system sales. | D-Wave’s 2025 Form 10-K reported revenue of USD 24.6 million for fiscal 2025 versus USD 8.8 million for fiscal 2024. It reported operating losses of USD 100.4 million and USD 77.2 million, respectively, and net losses of USD 355.1 million and USD 143.9 million, respectively. |
These are company-reported fiscal-year figures, not a fully normalized comparison. Accounting periods, acquisitions, business mix, and revenue recognition can differ; use audited statements and notes before drawing conclusions about relative growth or margins. A development contract may indicate customer interest, but it does not necessarily establish recurring, scalable demand.
Assess cash runway, financing, and dilution
Early-stage commercialization can require substantial spending before a company generates enough gross profit to fund operations. Review the latest filing for these items and track how they change from one reporting period to the next:
Rank #2
- Cash and equivalents, restricted cash, operating cash use, and any stated capital commitments.
- Debt, convertible securities, warrants, and other claims that could affect future share count or shareholder returns.
- Stock-based compensation, acquisition spending, and changes in shares outstanding.
- Customer concentration and reliance on government funding, partnerships, or milestone payments.
Estimate runway under more than one spending case rather than assuming recent cash use continues unchanged. Consider what happens if technical work takes longer, customer receipts arrive later, or investment rises. Strong technical progress does not prevent a company from needing to raise capital on terms that dilute existing shareholders.
Company filings also emphasize uncertainty in forecasts. D-Wave’s 2025 Form 10-K warns that actual results may differ materially from forward-looking statements. Treat projected milestones and commercial outcomes accordingly, and check later filings for evidence of what was achieved.

A revenue multiple is not a verdict, especially for a loss-making company with uncertain commercialization timing. Compare enterprise value with current revenue and gross profit, then ask what growth, margin improvement, and market share would be needed to support the market’s expectations. Use explicit assumptions rather than treating a large projected market as revenue that will automatically accrue to one listed company.
Build downside cases that include delayed technical milestones, slower customer adoption, lower gross margins, higher capital spending, or equity issuance. If modest changes to those assumptions produce radically different outcomes, the share price is especially dependent on uncertain future execution.
ESMA’s May 13, 2026 analysis describes the public pure-play companies as early in commercialization and operating at significant losses, while valuations experienced surges and corrections. It reported that four US-listed quantum companies temporarily exceeded USD 65 billion in combined market capitalization in late 2025, and that their weekly trading volumes surpassed USD 70 billion. Those are historical measures, not current valuations or a basis for judging today’s price.
ESMA also reported that generative-AI startups raised approximately USD 25 billion in 2024 and USD 35 billion in 2025—about 20 times and 8 times the amounts invested in quantum-computing startups, respectively. This illustrates the relative scale of investor funding; it does not establish the addressable market or future returns for quantum investments.

Best Value
Account for the risks that can overwhelm a promising roadmap
Quantum investing combines technology risk with the usual risks of young, capital-intensive businesses. A useful review considers how each could affect commercial adoption, cash needs, and the value of existing shares:
- Technical delay or failure: a roadmap milestone may arrive late or fail to translate into useful performance.
- Scaling constraints: a laboratory result may not scale into a reliable, accessible system that handles relevant workloads.
- Competition: other quantum architectures or improvements in classical computing could offer a better solution for a particular task.
- Unproven willingness to pay: customer interest, trials, or development contracts may not turn into sustained purchases or usage.
- Concentration and financing: dependence on a small number of customers or funders can make revenue and cash flow fragile, while continued losses can lead to further capital raising.
- Valuation volatility: prices can move sharply on funding expectations, milestone announcements, or projections of economic impact, even when commercial proof remains limited.
Also distinguish a pure-play quantum issuer from a diversified technology company that invests in quantum computing. For a diversified company, quantum may be strategically important while remaining too small to materially affect the company’s overall financial results.
Compare ways to get investment exposure
Pure-play shares concentrate exposure in one company’s technology, financing needs, and execution. Diversified technology companies spread business risk across other activities, but quantum may account for only a small part of their results. Funds can spread exposure across holdings, but their actual quantum focus depends on the mandate and portfolio.
Before choosing an ETF or other fund, check its prospectus, current holdings, fees, liquidity, and availability in your jurisdiction. ESMA reported that the first three EU-domiciled ETFs with a specific quantum-computing focus launched in 2025 and together held USD 0.6 billion in assets under management at the end of March 2026. ESMA also noted comparable US products, including a quantum-computing and machine-learning-themed ETF and a recently launched pure-play quantum fund. The asset figure is dated; it is not a current holdings or performance measure.
Quick Recap
A practical diligence sequence
- Define the exposure. Decide whether you are evaluating a pure-play quantum company, a diversified company with quantum activity, or a fund. Identify what portion of the business or portfolio is actually tied to quantum.
- Read the latest annual filing. Review the business description, revenue notes, risk factors, management discussion, cash-flow statement, and share-count disclosures. For the figures above, the cited company filings are fiscal 2025 Form 10-Ks.
- Map claims to evidence. For each important technical claim, record the architecture, metric, workload, test conditions, date, and whether it was independently or customer corroborated. Keep targets separate from achieved results.
- Trace revenue quality. Classify revenue by product or service, customer type, recurrence, concentration, and milestone dependence. Compare revenue growth with gross profit and cash collected.
- Stress-test financing. Model operating cash needs under slower and faster spending cases, then account for debt, convertibles, warrants, stock compensation, and possible new share issuance.
- Test the price against scenarios. Use more than one adoption and margin path, including delayed commercialization. State assumptions and consider whether the current price already depends on unusually strong outcomes.
- Revisit after new evidence. Compare later filings and customer disclosures with prior targets. A missed milestone, changed revenue mix, or new financing need can alter the investment case even if the long-term technology remains promising.
