Agencies' Q3 2026 earnings: where the value is moving
Q3 earnings landed in a cluster and told one story: media and data are growing, classic creative is shrinking, and every major group is pricing its future on AI plus fewer people.
WPP's creative revenue fell 5.1% while media returned to growth.

Publicis, the fastest-growing major, named the two-speed AI client.
03
Pricing is moving off the billable hour as a quarter of the work automates.

Creative is where the value is draining, even at WPP
What changedWPP's Q3 trading update (29 Oct) showed its media business back to growth (+0.3%, the first positive quarter since 2024) and production up 2.5%, while creative fell 5.1%, worse than the prior quarter. Group net sales were down 2.1%.
Why it mattersBudget is flowing to media, data and production while the traditional ideas-and-craft layer contracts at the best-resourced group in the world. That points to a structural reweighting of where clients see value, and it reaches well beyond WPP.

Consolidation has become a scale machine
What changedOmnicom reported $6.4bn in Q3 revenue, 7.2% core organic growth and an 18.2% adjusted margin about a year after closing the IPG merger, with a ~$900m cost-synergy target. It has also just won Coca-Cola's North America media account (Omnicom).
Why it mattersThe merged group throws off scale economics (data breadth, media leverage, synergy-funded pricing) that no independent can match, and it is winning blue-chip media while doing it.

Publicis names the "two-speed" AI client
What changedPublicis grew 5.0% organically, the fastest of the majors. CEO Arthur Sadoun described AI as a "two-speed boat": consumer-facing tools push clients to move fast externally, while internal transformation stays slow and costly. Publicis is investing in teams and data and tech rather than cutting, and expects AI agents to remove ~25% of repetitive tasks (Publicis).
Why it mattersThat gap, urgent outside and stuck inside, is where most agencies and their clients actually sit, and it is the hardest part to fix alone.

Everyone is buying data and AI capability
What changedA dense fortnight of deals, mostly about acquiring capability: Accenture Song bought data firm Sagacity; Serviceplan took a majority of AI consultancy Data Wizards; Hawke Media's largest-ever deal explicitly added "AI visibility" work (deal roundup).
Why it mattersMid-market agencies are buying their way to data and AI credibility rather than building it, and GEO (visibility in AI search) is now something buyers pay for by name.

The real margin lever is headcount
What changedAcross the three results the same mechanic recurs: Omnicom's ~$900m synergies, WPP's structural cost programme, and Publicis's ~25% task automation. With group organic growth barely positive, labour is the lever being pulled.
Why it mattersThe industry is rebuilding its delivery model around fewer people plus agents. Clients will start asking why the rate card still assumes the old headcount.

Pricing is moving off the hour
What changedThe quarter's clearest through-line is pressure on time-based billing. If a quarter of the work automates and the agency still bills by the hour, AI quietly cuts the agency's own revenue.
Why it mattersThe agencies that win reprice around value and outcomes before the billable hours evaporate under them.
What an agency should actually do with each of these depends on its model, its mix and its clients, which is the conversation I have with agency owners. If any of it lands, that is what the call is for.
