The CPaaS market grew 9.3% in 2025 to $14.88 billion, and Gartner is forecasting a further 13% rise to $17.03 billion before the year is out.
That consistent upward trajectory reflects just how central programmable, AI-enhanced communications infrastructure has become to enterprise operations.
Against that backdrop, Gartner has published its 2026 Magic Quadrant for Communications Platform as a Service (CPaaS), assessing 15 vendors across Leaders, Challengers, Visionaries, and Niche Players.
Twilio and Infobip sit comfortably at the top of the plot, separated by only the narrowest of margins, with Twilio edging ahead on Ability to Execute and Infobip fractionally leading on Completeness of Vision.
This year's edition also carries some notable changes from 2025, with Vonage returning to the Leader quadrant after slipping to Visionary last year, where it is joined by Proximus Global, which makes the same move up.
Elsewhere, Cisco moves from Visionary to Challenger, Tata Communications graduates from Niche Players to Visionaries, and three vendors also make their debut: Alibaba Cloud in the Visionaries quadrant, with Telnyx and GMS both entering as Niche Players.
Sinch retains its Leader position for another year, alongside Twilio and Infobip.
What is CPaaS?
Gartner defines communications platform as a service as a cloud-based platform that enables businesses to embed communications capabilities into applications across voice, SMS, email, messaging apps, and video.
Platforms also provide conversational capabilities, security, authentication, and automation.
In practice, CPaaS functions as a programmable toolkit for building multimodal customer experiences, which is why the market is increasingly intersecting with CCaaS, UCaaS, and CDP technologies.
AI sits at the center of where every major vendor is pointing its roadmap right now, and Gartner reflects that in its mandatory evaluation criteria, which now includes AI-powered bots and GenAI model integration alongside the core communications API requirements.
So, let’s take a closer look at how each vendor fared.
Gartner Magic Quadrant Leaders
Leaders demonstrate both a compelling vision for CPaaS and a consistent ability to execute against it. They shape market direction and support customers across a wide range of use cases.
This year's Leaders are:
- Twilio
- Infobip
- Sinch
- Vonage
- Proximus Global
Twilio
Twilio remains the market's benchmark and sits highest among all vendors on the Ability to Execute axis.
Its latest developments include global RCS support, new authentication tools, and Conversational Relay, which equips developers with the building blocks for more natural voice interactions and signals how Twilio is pushing CPaaS deeper into conversational AI territory.
What separates Twilio at scale is its data strategy. With CDP integration across Snowflake, Databricks, and other platforms, it can unify communications and customer data in a way that most competitors still can't match.
Gartner highlights this ability to combine data insights, AI, and omnichannel as a core strength, and it's only going to become more relevant as personalization demands increase.
Infobip
Infobip runs Twilio closest on the overall plot, nudging fractionally ahead on Completeness of Vision while sitting just behind on Ability to Execute.
Its strength lies in how it goes to market; while many CPaaS vendors are built for developers, Infobip sells outcomes, making it a natural fit for enterprise buyers who want results without needing to manage the underlying complexity themselves.
Gartner points to its early move into agentic AI through its AgentOS platform and adoption of Model Context Protocol servers as a headline differentiator, alongside a carrier ecosystem spanning over 800 global connections with broad regional coverage.
Sinch
Sinch retains its Leader status, with its CPaaS stack covering customer engagement applications, a developer API platform, and a voice-focused Super Network, built through a combination of acquisitions and internal development that has given it one of the widest channel ranges in the market.
Its partner ecosystem is also a genuine commercial advantage. With over 1,000 partners and more than 500 integrations spanning Salesforce, Microsoft, SAP, and others, Sinch gives customers strong connectivity to the systems they are already running, which reduces friction and speeds up time to value.
Gartner further highlights Sinch's AI and ML-driven fraud controls as a security differentiator.
Vonage
Vonage's return to the Leader quadrant is one of the more interesting storylines in this year's report.
Having slipped to Visionary in 2025, the Ericsson-owned vendor has made a clear case for promotion.
Gartner recognizes Vonage's “AI-ready” API suite as a headline strength, backed by MCP server tooling that gives developers greater visibility throughout the build process.
Its video API capabilities are also flagged as among the most extensive and scalable in the industry – a meaningful differentiator in an area where several peers still lag.
Proximus Global
Formed in December 2024 through the merger of BICS, Telesign, and Route Mobile, Proximus Global enters the Leader quadrant as one of the newer consolidated entities in the CPaaS space.
The combination brings a broad channel portfolio, direct RCS connectivity with orchestrated fallback, and a network backbone with direct control over quality and latency.
The combined entity is also actively expanding beyond its European roots, building out presence in APAC, the Middle East, LATAM, and North America. That geographic ambition, backed by owned infrastructure rather than reseller arrangements, strengthens the case for its Leader placement.
Gartner Magic Quadrant Challengers
Challengers have strong operational presence and execution track records, but may lack the forward-looking vision of Visionaries when it comes to long-term innovation.
This year's Challengers are:
- Cisco
- Tencent Cloud
- Bandwidth
Cisco
Cisco moves from Visionary to Challenger this year, a shift that reflects its strong operational track record and delivery consistency.
