What Does WARC Forecast by Channel?
WARC headlined its October 7 update “Global advertising spend surges 11.9% to $1.34trn this year amid consumer caution” (WARC). Suzy Young, head of WARC Media data, said in the release: “These are unusual times for advertising. Investment is accelerating even as many consumers face cost-of-living pressures and become more cautious with spending.” She called it an “apparent contradiction” reflecting “an increasingly uneven economy,” where growth, “particularly from the AI boom,” benefits some companies, sectors and consumers more than others (WARC release). Social media is forecast to grow fastest, up 21.3% to $394.6bn.

Forecasts, not outcomes; growth rates are year on year as given in the release. Channels overlap with company totals and are not exhaustive. The full WARC report is for subscribers and was not read; the release gives no channel definitions.
The chart shows the forecast value of five channels named in the release; it covers paid advertising only, not earned media.
How Concentrated Is the Market?
WARC forecasts Alphabet, Amazon and Meta at 59.7% of global ad spend excluding China. We report this as WARC’s forecast; the release gives no company-by-company breakdown and no comment from any of the three companies, so we make no claim about any one company’s revenue.

What About Audio and Podcasts?
The WARC release we read contains no audio or podcast figures, and WARC’s own pages we could open gave none either. A forecast for online audio is circulating in trade coverage attributed to WARC, but we could not find it in a WARC document, so we do not repeat it. For why podcast revenue estimates differ, see why two IAB studies disagree about podcast ad growth.
What Does It Mean for Earned Media?
The forecast does not measure PR. Our interpretation, not WARC’s: when most spend flows through a few platforms’ ad systems, those platforms’ distribution rules matter to every brand, including for unpaid posts. Meta’s new monthly cap on links for some Facebook Pages is one example (see Meta’s link limits). It is a reason to keep owned channels and press relationships, not a reason to avoid platforms. See also what share of voice is and whether Google pays publishers for AI Overviews.
What This Means for Anyone Buying a Placement
A placement in a trade or national outlet is not part of these figures. Do not accept a vendor’s use of an ad forecast as evidence that a placement will pay off. Sponsored content is advertising and should be disclosed; no outcome is guaranteed.
Methodology and Limitations
Four limits apply. First, we read WARC’s public pages and its release as published by Podnews, not the subscriber-only report. Second, forecasts change with each quarterly update. Third, channel definitions are not given. Fourth, the release does not break out the three companies.
Conclusion
WARC forecasts a larger and more concentrated paid market, with three companies taking most of it outside China. For PR buyers it is context about where advertising money goes, and no evidence about earned coverage.
