Market forecasts from published reports
Market research firms, consultancies and industry bodies publish estimates of the market for quantum technologies, each with its own scope, base year and horizon. This page lists the estimates their publishers state on a public page, with the spread for each segment and horizon year. The portal makes no forecast of its own: it does not average, add up, extrapolate or convert the estimates, and an amount a publisher does not state reads Not stated.
How far apart are the estimates?
For each segment and horizon year, the lowest and the highest value a publisher states, in the currency it uses. The spread is not a forecast: the estimates count different things, as the notes below explain.

Why the scopes differ
- Quantum computing: Publishers differ on whether they count hardware only, hardware with software and services, cloud access, or the revenue of pure-play vendors only; a market of providers is not the economic value created for users.
- Quantum communication and cryptography: Some estimates cover quantum key distribution only, others all quantum communication or quantum cryptography; most do not say whether post-quantum cryptography software is counted, and markets of one publisher overlap.
- Quantum sensing: Publishers differ on the instruments counted (atomic clocks, magnetometers, gravimeters, imaging) and on whether components and services are included.
- Quantum technology, all segments: A total may cover only computing and sensing, or every quantum technology; a total of one publisher is not the sum of the segment estimates of others.

Definitions: Published market-size estimates for quantum technologies; Spread of market estimates by segment and horizon year
Publishers not included
An estimate is listed only when its publisher states it on a public page the portal could read. These publishers were tried and left out.
- McKinsey & Company: The page refused automated reads (2026-10-29). Quantum Technology Monitor pages timed out or showed an interactive graphic without readable text; its estimates are left out.
- IDTechEx: The page refused automated reads (2026-10-29). The report pages on idtechex.com returned no readable text; the quantum computing estimate comes from the announcement on a research site hosted by IDTechEx, and no figures were found for its sensing and communication reports.
- MarketsandMarkets: The page refused automated reads (2026-10-29). Press release pages answered HTTP 403 to automated reads.
- Fortune Business Insights: The page refused automated reads (2026-10-29). The report page answered HTTP 403 to automated reads.
- The Quantum Insider: The page refused automated reads (2026-10-29). The market article redirected to a blocked address; its estimate is left out.
- ResearchAndMarkets: No estimate of its own found (2026-10-29). Its listings resell reports of other publishers; no estimate of its own was found, and its press release on Business Wire answered HTTP 403.
- Precedence Research: Not a comparable market-size estimate (2026-10-29). The quantum sensor page states years that do not match its own heading and counts light sensors that most definitions of quantum sensing leave out; left out until a consistent edition appears.
- Boston Consulting Group: Not a comparable market-size estimate (2026-10-29). The economic value for users ($450 billion to $850 billion by 2040) is not a market size and is not listed; the provider market of the same article is.
- Mordor Intelligence: No estimate of its own found (2026-10-29). No report page of its own was found.
