This entry is the short answer. Every figure above, with its source and date, the regional breakdown, traffic and market-size detail and the 2026 US surge, is maintained in the annual report: the State of RCS 2026. Treat the report as the source of record and this page as the quick read; for the US table on its own, see US adoption at a glance.
Adoption figures vary by source and by what's being counted (active users vs monthly active users vs RCS-capable devices), so they should always be attributed. The direction, however, is unambiguous: every credible source shows steep growth, accelerated by Apple's 2024 support; Infobip, for one, reported business RCS traffic on its platform growing 5x in 2024, with the largest spike after Apple's launch.
For the US specifically, which carriers support RCS and does Apple support RCS give the carrier and iPhone detail behind the reach figure, and RCS vs SMS explains what the remaining share receives instead.
- ~1.1B active users in 2024 (Juniper Research, September 2023); ~3.8B by end of 2026 (~40% of mobile subscribers) is Juniper's February 2022 forecast.
1 billion RCS messages/day in the US as of May 2025 (Google); >80% smartphone reach in US/France.
- Business RCS traffic ~33B messages globally in 2024, with ~50B forecast for 2025 (Juniper Research, November 2024); Infobip reported 5x business RCS traffic on its platform in 2024 after Apple support (vendor-reported).
RCS market size
Estimates of the RCS market vary widely by source and methodology, but most put it in the high single-digit billions of dollars in 2025-2026, growing to the tens of billions over the next decade. Recent analyses peg the global RCS market around $9-10 billion in 2026, with projections ranging from roughly $19 billion by 2028 to $28-$35 billion by 2035 depending on the report. On the business side specifically, Juniper Research forecasts RCS-for-Business mobile-operator revenue rising from about $2 billion in 2026 to $6.5 billion by 2030.
Because market-sizing reports differ on scope (consumer plus business, business only, operator revenue vs total spend), the honest way to present this is a range with sources, not a single "the market is $X" figure. The consistent finding across them is double-digit annual growth.
- Global RCS market ~$9-$10B in 2026 (e.g., ~$9.56B, 360iResearch-type estimates); projections ~$19B by 2028 to ~$28-$35B by 2035 (varies by report).
- RCS-for-Business operator revenue: ~$2B (2026) → ~$6.5B (2030), a ~225% increase (Juniper Research).
- Figures vary widely by source and scope, always attribute and date.
RCS growth rate
RCS is one of the fastest-growing messaging channels. Market analyses commonly cite compound annual growth rates from the mid-teens to the mid-30s percent depending on scope, and usage growth has been even sharper around key milestones: Infobip reported business RCS traffic on its platform growing 5x in 2024 after Apple added support, and Juniper put business-messaging volume at about 33 billion messages in 2024 with a forecast of 50 billion for 2025. Juniper Research projects RCS-for-Business operator revenue to grow about 225% between 2026 and 2030.
Two kinds of "growth rate" get quoted, so separate them: market-value CAGR (mid-teens to mid-30s percent, by report) and usage/traffic growth (much steeper near adoption milestones like Apple's support). Both point the same way, rapid, sustained expansion.
- Market-value CAGR estimates range ~15%-35% depending on the report and scope.
- Infobip reported 5x business RCS traffic on its platform in 2024 (Apple support effect, vendor-reported); business messages ~33B (2024) → ~50B (2025 forecast), Juniper Research.
- RCS-for-Business operator revenue projected +225% from 2026 to 2030 (Juniper Research).
