IonQ boosts 2026 revenue outlook while D-Wave Quantum relies on a growing contract backlog to drive long-term growth, even as analysts warn the stock remains expensive at current levels.
Quantum computing firms show divergent growth paths as IonQ lifts its 2026 revenue guidance to $450-$460 million. Meanwhile, D-Wave Quantum reports lumpy quarterly results but maintains a strong $40.7 million backlog, fueling projections that its revenue could triple by 2030 despite current valuation concerns.
D-Wave's revenue is heavily dependent on large, infrequent system sales, which creates significant year-over-year fluctuations compared to its steady but smaller cloud-access business.
