Premium digital inventory and the US will keep media inflation high through 2027

WFA’s latest Outlook poll of media price inflation forecasts suggests global media costs will continue rising into 2027. 2026 media price inflation is now estimated at 4.5% (excluding hyperinflationary markets Turkey and Argentina), compared with the 4.4% global forecast published in April.

For 2027, the global forecast remains at 4.5% (again excluding Turkey and Argentina), suggesting little overall relief next year. The previous poll was taken shortly before the flare-up of hostilities in the Middle East, but that’s not the cause of current and future inflationary pressure. 

Digital auction markets are strengthening as TV cools 

The strongest current inflation forecasts are increasingly concentrated in digital channels. Paid search is forecast at 5.4%, retail media at 5.2%, social video at 4.4% and social display at 4.1% for 2026. 

At the same time, expectations for television have softened since the Outlook poll taken in April. The previous report identified linear TV as the fastest-inflating channel at 7.7%, driven by declining audiences and exceptional World Cup demand. The latest forecast is notably lower, although audience scarcity continues to create significant inflation within certain markets, hard-to-reach audiences and prime sporting inventory. 

The hottest spot within the poll is within the UK, as hard-to-reach audiences continue to migrate from linear TV. 

There’s a different story for Connected TV. Rapid audience and budget migration is increasing advertiser demand but expanding streaming inventory is generally preventing the same degree of price pressure. This was already visible in April and remains evident in the latest forecasts. 

The US remains central, but the geographic picture is mixed 

Much of the global price inflation seems to be driven by the US, where the latest 2026 forecast stands at 4.6% compared with the 4.0% forecast published in April, with particularly strong pressure in paid search and social display.  

Germany, Mexico and the UAE have also strengthened. Mexico contributors point to growing retail media investment, including increasing competition across major commerce platforms, alongside the additional impact of the World Cup in summer 2026 on this year’s inflation numbers. 

Elsewhere expectations have softened, including in the UK, South Korea, Spain, France, Belgium and parts of Asia-Pacific. India remains among the fastest-inflating major markets at around 9%, although slightly below the 9.5% forecast published in April. 

Scarcity matters more than demand 

A consistent theme is that supply, rather than simply advertiser demand, increasingly determines inflation. 

India’s CTV market, for example, combines rapidly growing advertiser demand with premium inventory constraints. Korean retail media faces a similar imbalance between investment growth and limited premium onsite inventory. In the UK, declining linear TV audiences continue to create scarcity even while advertiser revenue and budgets migrate towards digital alternatives. 

That distinction matters for advertisers: a market can experience weak economic or advertising growth while the cost of reaching a particular audience still rises sharply. 

Overall 

Media price inflation is becoming increasingly uneven. Pressure is concentrating around scarce, high-intent and measurable inventory, while expanding supply is helping to moderate costs elsewhere. 

This nuance goes far beyond the simple 4-5% global price inflation figure, and it is why the management of media cost inflation should be a bottom-up exercise, taking in the details.
