Here is how to hold one. > **Interactive figure — market-scope.** Switch between the three published estimates. The bars are what each firm reports; the gap between them is what nobody puts on a slide. > Available at https://cpaas.co/en/insights/reading-a-market-forecast ## The numbers disagree, and that is informative As published: Juniper Research projects the CPaaS market surpassing US$34 billion by 2026. Gartner's forecast puts spending at US$15.7 billion in 2025, growing to US$27.4 billion by 2029. Mordor Intelligence sizes 2026 at US$21.27 billion. These are all serious firms. The spread is not sloppiness — it is definitional. ```diagram:bars # The same market, as published, for 2026 Juniper Research | 34 | Over US$34bn by 2026, up from about US$30bn in 2025 Mordor Intelligence | 21.3 | US$21.27bn in 2026, reaching US$41.05bn by 2031 Gartner | 15.7 | US$15.7bn in 2025, growing to US$27.4bn by 2029 > Figures as each firm publishes them. The gap is definitional — chiefly whether carrier fees passed through a platform are counted. ``` ## What moves a number by a factor of two **Pass-through fees.** When you send an SMS, a large share of the price is the carrier's, collected by the platform and handed on. Count that and the market is enormous; count only what platforms keep, and it is much smaller. Both are defensible; they are different questions. **Where the boundary sits.** Is a contact-centre suite CPaaS? Is email delivery? Is a video SDK? Firms draw this line differently, and each line is a different market. **Spend versus revenue.** Buyer-side spending and vendor-side revenue diverge, because one includes things the other does not. ## The three questions to ask of any figure 1. **What is inside it?** If the deck cannot tell you whether carrier pass-through is included, the figure is decoration. 2. **Who is the population?** Global totals say very little about whether your segment, in your region, is growing. 3. **What is it being used to argue?** A growth number in a vendor deck is there to make a purchase feel inevitable. That is not a reason to disbelieve it; it is a reason to notice the work it is doing. ## What forecasts are actually good for Direction and relative magnitude. Every firm above agrees this market grows at a healthy double-digit rate, and that is a genuine signal. What they cannot tell you is whether *you* should buy, build, or do nothing — because none of them modelled your volumes, your regions, or the cost of the thing you would not have to do if you bought. Use forecasts to understand the weather. Do not use them to decide what to wear. ## Three questions that expose a forecast **What is the unit of the thing being counted?** Revenue, spend, seats, messages, and "market opportunity" are five different quantities, and slide decks move between them without saying so. **What is the base year, and is it actual or estimated?** A forecast anchored on an estimated base compounds the estimate. A five-year projection from a soft base is an opinion with a chart attached. **Is the growth rate applied to the whole, or to a segment that is growing faster than the whole?** This is the most common sleight of hand, and it is usually not deliberate: a company measures the fastest-growing part of its own business and extrapolates it across a category. ## Bottom-up beats top-down for your own decision The figure you actually need is not the market's size. It is your volume, your price and your cost, and you can compute it from things you already know. Count the events in your business that would trigger a message — orders, appointments, renewals, support contacts. Multiply by the messages each needs. Apply a realistic rate for your markets, remembering the encoding penalty on non-Latin scripts. That number is worth more than any published total, because it is about you. Then use the published forecasts for the one thing they are genuinely good for: sanity-checking direction, and knowing whether you are entering a category that is consolidating or fragmenting. ## What to take away - Published market sizes for this category differ by more than a factor of two, and none is wrong. - Ask what is inside the number before quoting it; pass-through fees are the usual explanation. - Where methods disagree on magnitude but agree on direction, direction is the robust finding. - Build your own bottom-up number. It is the only one that answers your question. ## Sources - [Forecast Analysis: Communications Platform as a Service, Worldwide](https://www.gartner.com/en/documents/6565602) — Gartner - [CPaaS Market Research Report: Size, Share, Trends 2025-29](https://www.juniperresearch.com/research/telecoms-connectivity/communication-services/cpaas-research-report/) — Juniper Research - [Communication Platform-as-a-Service Market](https://www.mordorintelligence.com/industry-reports/communication-platform-as-a-service-cpaas-market) — Mordor Intelligence --- Published by the company behind five products in this category.
