InvestingPro Flagged D-Wave Quantum as Overvalued Before 45% Drop
D-Wave Quantum (NASDAQ: QBTS) has become a notable example of the gap that can emerge between investor enthusiasm and underlying fundamentals. In October 2025, when the quantum-computing stock was trading at $32.19, InvestingPro’s Fair Value analysis estimated its intrinsic value at $18.88 and flagged the shares as about 41% overvalued. By September 2026, D-Wave had fallen to $17.41, a decline of 45.9% from the level highlighted in the original analysis.
The move does not prove that a single valuation model can consistently predict stock prices. But the D-Wave case is useful because it shows what can happen when a highly speculative technology theme gets ahead of a company’s financial performance.
It also highlights an important distinction for investors: a promising technology does not automatically make a stock attractively valued.
Why InvestingPro Flagged D-Wave Quantum
InvestingPro identified D-Wave on October 21, 2025, when the company was reporting revenue of $24.144 million, an EBITDA loss of $84.362 million and negative earnings per share of $1.37, according to the InvestingPro analysis. At the time, the stock price of $32.19 was substantially above the platform's estimated Fair Value of $18.88.
The valuation concern came against a backdrop of intense enthusiasm for quantum computing.
D-Wave's shares had already experienced sharp gains in 2025, including increases of 136% in May and 58% in September, according to InvestingPro. Such rapid price movements can cause valuation multiples to expand much faster than a company's revenue and earnings potential.
Fair Value is essentially an estimate of what a company may be worth based on financial and valuation assumptions rather than the price investors are currently willing to pay. InvestingPro says its methodology combines several approaches, including discounted cash-flow models, comparable-company analysis and analyst expectations.
That makes the metric useful as a valuation reference, but not a guaranteed prediction of where a stock will trade.
D-Wave Stock Fell to the Fair Value Zone
The subsequent decline was substantial.
InvestingPro's analysis says D-Wave reached a Fair Value level of $16.99 in August 2026. By September, the shares were trading around $17.41, compared with $32.19 when the original overvaluation signal was identified.
That represents a 45.9% decline.
The path was not necessarily a straight line, however. Quantum stocks have remained highly volatile, with investors reacting to technological announcements, government support, partnerships and expectations about the future commercial market.
That volatility is particularly important for D-Wave because conventional valuation measures are difficult to apply to an early-stage technology company whose potential revenues are tied to a market that is still developing.
The Fundamental Picture Has Remained Challenging
D-Wave's latest reported financial results illustrate the tension between its technological ambitions and current revenue scale.
For the second quarter of 2026, D-Wave reported revenue of $3.1 million, essentially unchanged from the same quarter a year earlier. The company recorded a GAAP net loss of $48 million, or $0.13 per share, while its adjusted EBITDA loss widened to $37.1 million from $20 million a year earlier.
Operating expenses increased sharply as D-Wave invested in product development and its go-to-market efforts.
For the first six months of 2026, revenue was $5.9 million, down from $18.1 million a year earlier. However, the comparison was affected by a $13.7 million revenue contribution from the sale of an annealing quantum-computing system in the first half of 2025.
So the revenue decline needs context rather than being interpreted as a simple collapse in demand.
More encouragingly, D-Wave reported first-half bookings of $35.5 million, up 1,120% from $2.9 million in the first half of 2025. Remaining performance obligations also rose to $40.7 million, up 668% year over year.
These figures suggest that bookings and contracted future business are growing much faster than recognized revenue.
Why Bookings Matter for D-Wave Investors
Bookings represent orders or commitments that can translate into future revenue, while remaining performance obligations represent contracted work that has not yet been recognized as revenue.
For D-Wave, this distinction is particularly important.
The company said its first-half bookings included a $20 million system sale, with the associated revenue to be recognized in subsequent quarters. It also said approximately 57% of its $40.7 million in remaining performance obligations was expected to be recognized over the next 12 months.
That gives investors a potential indicator of future revenue growth, but it does not eliminate execution risk.
The company still needs to deliver systems and services, convert customer interest into recurring commercial use and control its expenses as it scales.
D-Wave Has Also Received Significant Government Support
The bearish valuation story should not obscure the developments supporting D-Wave's long-term opportunity.
In September 2026, D-Wave finalized an agreement with the U.S. Department of Commerce for up to $100 million under the CHIPS and Science Act. The funding is intended to support research and development involving semiconductor technologies for quantum computing, including annealing and gate-model systems.
The company has also continued expanding its customer relationships.
Its second-quarter release identified engagements with companies and organizations including AT&T, Nasdaq Verafin, Oki Electric Industry, Shionogi and Unisys.
These developments are important because the long-term value of D-Wave ultimately depends on whether quantum computing becomes commercially useful at scale.
Government funding and enterprise partnerships can accelerate that process, but neither guarantees future profitability.
D-Wave Is Pursuing Two Quantum Computing Approaches
Another important change is D-Wave's expansion beyond its traditional quantum-annealing focus.
The company now describes itself as a dual-platform quantum computing company, working on both annealing and gate-model systems. Its roadmap includes a 100,000-qubit annealing system targeted for 2031, while its gate-model roadmap includes milestones extending into the early 2030s.
Quantum annealing is designed for certain optimization problems, while gate-model quantum computing is the approach more commonly associated with general-purpose quantum algorithms.
Expanding into both areas potentially broadens D-Wave's addressable market, but it also requires substantial research, engineering and capital spending.
Why Quantum Stocks Can Become Extremely Volatile
Quantum computing remains an emerging industry. Commercial applications are developing, but the technology is still far from having the scale and maturity of established computing markets.
That creates a valuation challenge.
Investors often value emerging technology companies based partly on what the market could become years from now. When expectations rise sharply, stock prices can move far ahead of current revenue.
D-Wave's 2025 share-price surge illustrates that dynamic. The subsequent 45.9% decline shows the other side of the equation: when expectations are recalibrated, high-growth technology stocks can experience substantial corrections even if the underlying technology continues to advance.
For investors, this means separating technology potential from present-day business performance.
What Investors Should Watch Now
D-Wave's investment story has changed since the October 2025 valuation signal. The stock is now much closer to the Fair Value levels identified by InvestingPro, while the company has also added government funding, customers and a broader technology roadmap.
The most important indicators going forward include:
Revenue conversion: whether bookings translate into recognized revenue.
Remaining performance obligations: whether the current $40.7 million pipeline continues to grow.
Commercial adoption: whether customers move from experiments to production applications.
Cash consumption: D-Wave reported $546.2 million in cash and marketable investment securities at June 30, 2026, but continued losses make cash usage important to monitor.
Operating expenses: whether spending growth begins to moderate as commercial activity increases.
Quantum technology milestones: whether the company's annealing and gate-model roadmaps remain on schedule.
Government support: how the $100 million CHIPS award contributes to research and manufacturing.
Competitive position: how D-Wave performs against other emerging quantum companies and larger technology players.
Bottom Line
The D-Wave Quantum stock story demonstrates why valuation matters even in industries with potentially transformative technology.
InvestingPro's Fair Value analysis identified D-Wave as significantly overvalued in October 2025, when the shares traded at $32.19 versus an estimated Fair Value of $18.88. By September 2026, the stock had fallen 45.9% to $17.41.
At the same time, D-Wave's business is showing some encouraging signs, particularly the sharp increase in bookings, higher remaining performance obligations, new enterprise engagements and up to $100 million in U.S. government funding.
The key question for investors now is therefore not simply whether D-Wave's shares were previously overvalued. It is whether the company's future commercial growth can eventually justify the expectations embedded in its valuation. Revenue growth, cash usage, customer adoption and execution against its quantum roadmap will be critical indicators.
