Why the biggest reviews of 2026 turned on conflict and data
What changedPublicis's PepsiCo win on 2 September (Pepsi, Gatorade and Lay's across 200+ markets) conflicted it out of Coca-Cola's global media review (Adweek). By 12 September, WPP was reported set to keep Coca-Cola's global media, data and technology account, run through its Open X unit across roughly 200 brands, while Coke's North America media is contested between Omnicom and Dentsu (Exchange4media).
Why it mattersThe two biggest reviews of the year were settled by category conflict and by who runs the client's data and tech stack. New business gravity is moving towards data custody and exclusivity. Every mega-win also vacates an incumbent somewhere, which opens space further down the market for agencies watching closely.
Is the holding-company tier splitting in two?
What changedA sector outlook published on 16 September set out the gap (Investing.com). Publicis grew revenue from $13.4bn in 2021 to $20.4bn in 2025 at a ~17.4% operating margin. WPP's EBITDA is down ~62% since 2021 to around $0.75bn, a ~4.1% margin. Under Cindy Rose's Elevate28 plan WPP cut ~1,260 jobs in the first half and flagged up to ~1,000 more by year-end, while holding ~$405m a year of tech spend behind WPP Open (Digiday).
Why it mattersThe top tier is separating into one scaled AI and data winner and one giant shedding people. Instability at the top loosens senior talent and mid-market accounts, which is a real opening for independents that can offer senior attention, continuity and no conflicts.
AI is breaking hourly pricing
What changedThe pricing tension many agencies have felt quietly is now out in the open: when AI turns a 10-hour task into two, hourly billing passes the whole saving to the client. Fixed-scope, outcome-based and productised pricing are the documented responses. Campaign's State of the Pitch 2026 found around 90% of agencies still pitch for free, the same cost-of-winning problem from another angle.
Why it mattersThis is the biggest live question in agency economics. Agencies that separate price from hours keep the efficiency AI creates. Those that don't give it back as a silent discount, and pay for the pitch on top.
Agentic tools are moving into delivery
What changedAgent-based systems have spent this year moving from demos into delivery and media buying. FreeWheel shipped an agent layer piloted inside PMG's operating system in March (FreeWheel). Stagwell built its pitch around an agentic OS called The Machine in January (MediaPost). Accenture Song bought creator agency Whalar (Accenture). The September sector outlook still called the near-term AI threat to agencies "largely theoretical", while describing spending pressure as "unmistakably real".
Why it mattersThe competitive set now includes holding-company AI platforms, consultancies with creator and AI stacks, and AI-native shops. Using AI is table stakes. The defensible ground for an independent is judgement, orchestration and accountability for the result.
How an agency answers each of these depends on its clients, its margins and where its work comes from. Working that through is the conversation I have with agency owners, and it is what the call is for.
