The first half of 2026 delivered the Olympics, a resurgent NBA Finals, the FIFA World Cup, and continued growth across streaming and digital media. Yet advertising spend grew just 4% year over year—well below the roughly 10% growth Guideline has historically seen in comparable event-heavy years.

In this episode of Media Monitor, Kelly Sweeney and Sean Wright break down what Guideline’s data says about the first half of 2026, where advertising dollars are moving, which categories are gaining or cutting spend, and why major tentpole events haven’t been enough to produce a stronger market.

They examine continued weakness among automakers, growth from AI and SaaS advertisers, social media’s strong first half, CTV’s continued gains, the shift of World Cup dollars from linear television toward streaming, and the surprising resilience of out-of-home advertising.

Sean also looks ahead to the second half of 2026, including the effects of softer consumer spending, inflationary pressure, political advertising, and the early testing of AI search as a new advertising channel.

Plus: why advertisers may be able to use AI to move faster, while consumer behavior still moves at the “speed of human.”
