This global quantum computing market analysis and forecast reflects a segment transitioning from research-driven activity toward early commercial opportunity, with accelerating revenue growth, shifting deployment models, and increasing realism about structural risks. The market reached an estimated $1.4 billion in 2025 and is projected to grow by approximately 30% annually to more than $3 billion by 2028.
Revenue optimism remains strong, on-premises systems are projected to become the largest market segment by 2028, application focus is narrowing toward simulation use cases, and partnership activity is supporting commercialization. At the same time, dependence on government funding and concerns about potential investment contraction underscore continued structural vulnerability.
Quantum computing remains at an early stage of technological maturity, but commercialization dynamics are strengthening. Companies are increasingly working toward commercial-grade systems with improved reliability, more standardized integration, and clearer maintenance expectations. Survey results indicate that 37% of companies expect revenue growth in 2026 exceeding 25%, and no respondents anticipate declining revenue.
Application focus continues to center on simulation. Computational chemistry (26%) and materials science (22%) together represent nearly half of identified near-term use cases. Cryptography (16%) remains strategically relevant, while enthusiasm for artificial intelligence (AI) and machine learning (ML) applications has moderated. This sharpening focus suggests a more disciplined assessment of where quantum advantage is most likely to emerge in the near term.
More than half of respondents (54%) see some probability of a “quantum winter” by 2031, defined as a sustained decline in quantum research and development (R&D) investment exceeding 25%. The increase since last year in “somewhat likely” responses indicates rising caution, though respondents are confident in their own companies’ prospects. This suggests that anticipated contraction may be viewed as consolidation, where stronger players gain share, rather than systemic decline. Overall, the quantum computing segment is advancing beyond pure research toward more durable commercialization, but on a disciplined and risk-aware path.
