QBTS or IONQ: Which Quantum Stock Wins After January Sell-Off?
Read MoreHide Full Article
Key Takeaways
QBTS shares slid 13.4% after Jan. 23 as trade-war fears pushed investors away from speculative quantum stocks.
D-Wave generates revenues from quantum systems, QCaaS and services, backed by more than 100 paying customers.
IONQ posted 222% revenue growth in Q3 2025, but widening 2026 loss estimates cloud near-term returns.
On Jan. 23, 2026, quantum computing stocks experienced sector-wide weakness as broader risk sentiment shifted due to a combination of global macro and geopolitical uncertainties that heightened investor caution. Fresh trade-war and tariff fears, especially U.S. tariff threats toward European allies and potential retaliatory trade actions, spurred a shift toward safe-haven assets and away from highly speculative quantum technology names, which came under pressure.
D-Wave Quantum (QBTS - Free Report) has lost 13.4% since Jan 23. IonQ (IONQ - Free Report) also saw a 12.1% pullback, reflecting cooling sentiment toward high-valuation, early-stage quantum plays, consistent with broader sector de-rating as speculative tech valuations normalized and some investors took profits on richly priced, long-horizon innovation stocks.

The durability of this pullback is still uncertain, but the contrast between the two names is becoming clearer in 2026. IONQ continues to command leadership on advanced technology and long-term platform potential, whereas QBTS is gaining attention for nearer-term revenue visibility. Let's delve deeper.
Reasons to be Bullish on QBTS in 2026
QBTS has entered 2026 with a strong setup driven by real commercial adoption. Unlike many quantum peers still focused on R&D, D-Wave is already generating revenues from production-ready quantum systems, cloud-based QCaaS offerings and professional services, supported by over 100 paying customers, including Global 2000 companies. Business momentum picked up in 2025 with the sale and deployment of Advantage and Advantage2 systems, including a €10 million European Advantage2 contract and deployments tied to U.S. defense and enterprise customers.
Financial performance also improved meaningfully, with triple-digit revenue growth, expanding gross margins and a cash balance exceeding $800 million at the end of the third quarter of 2025, giving the company ample flexibility to scale operations. On the technology front, the ongoing progress in superconducting gate-model systems broadens its long-term market opportunity, supporting a positive outlook for 2026.
QBTS Estimate Trend
Over the past three months, its loss per share estimate for 2026 has narrowed to 19 cents from a loss of 23 cents. This implies a 7% improvement from the year-ago projected EPS.

Reasons to Be Bullish on IONQ in 2026
IonQ has entered 2026 with strong momentum supported by rapid revenue growth, technical progress and a strong balance sheet. In the last-reported third quarter of 2025, the company delivered 222% year-over-year revenue growth, exceeding the high end of guidance by 37%, highlighting accelerating commercial adoption across quantum computing and adjacent platforms. Technologically, IonQ achieved several key milestones ahead of schedule, including the AQ 64 Tempo system, a world-record 99.99% two-qubit gate fidelity and continued advancement toward fault-tolerant, scalable gate-based quantum computing. Strategic acquisitions such as Oxford Ionics and Vector Atomic expanded IonQ’s capabilities across quantum computing, networking, sensing and cybersecurity, broadening its addressable market and strengthening its platform approach. Financially, IonQ finished the third quarter of 2025 with $1.5 billion in cash and investments and subsequently closed a $2 billion capital raise. Together, execution, scale and capital strength support a bullish outlook for 2026.
IONQ Estimate Trend
Over the past three months, its loss per share estimate for 2026 has widened to $1.74 from a loss of $1.63. This implies a 65.8% improvement from the year-ago projected EPS.

QBTS-IONQ Valuation
QBTS currently trades at a forward 12-month Price-to-Sales (P/S) of 188.2X compared with IONQ’s 72.5X.

Our Take
From an investment perspective, D-Wave Quantum looks better positioned than IONQ despite trading at a richer valuation, as that premium is increasingly supported by near-term revenue visibility, improving loss estimates and active commercial deployments. Meanwhile, IONQ remains more sensitive to valuation resets, with widening loss estimates and returns tied heavily to future platform milestones rather than current monetization. Accordingly, QBTS’ Zacks Rank #3 (Hold) reflects a more balanced risk-reward setup, while IONQ’s Zacks Rank #4 (Sell) signals elevated near-term earnings risk.
