Quantum Computing as a Service: Market Size & Forecast 2026

The global Quantum Computing as a Service (QCaaS) market sits at approximately USD 5.2 billion in 2025 (base year), growing at roughly 28.5% CAGR toward a 2032 endpoint near USD 26 billion. The category is structurally supply-constrained, not demand-constrained: cloud-delivered QPU hours are gated by rare-earth and helium-3 feedstock, by cryogenic dilution-refrigerator fabrication lead times, and by a small handful of superconducting, trapped-ion, photonic, neutral-atom, and annealing modalities that do not interoperate. Pricing for a premium-segment gate-based QPU hour ran USD 4,200-4,800 across major regions in 2026-Q2. The market is consolidating fast; IonQ alone has closed multiple acquisitions over the trailing 18 months. > Synthesised from secondary and publicly verifiable sources via Claight Category Watch:
