AI Buying Platforms to Handle 27% of US Ad Spend by 2030
A new forecast from Madison & Wall indicates that AI-driven ad buying platforms will manage 27% of U.S. ad spend by 2030. The report highlights that global ad revenue reached $1 trillion in 2024 and is projected to hit $1.3 trillion by the end of 2026, an 11% year-over-year increase. AI companies are both creating tools that enhance ad buying efficiency and becoming significant ad buyers themselves, fueling a circular growth pattern. However, the report warns that AI could also cause a downturn if the venture capital funding driving this growth subsides. The forecast also notes a 12.9% growth in global ad revenue in Q2 2026, with a predicted 9.8% increase in Q3 excluding U.S. midterm political ads.

AI Investment Spurs Global Ad Growth in 2025
WPP Media’s This Year Next Year forecast indicates the global ad market is set for positive momentum into 2026, with 2025 growth upgraded to 8.8% and 2026 projected at 7.1% (excluding US political advertising). The acceleration is attributed to several factors, notably an AI investment boom that has spurred economic activity; Harvard economist Jason Furman is cited as noting that without AI investment US real GDP growth would have been only 0.1% in the first half of 2025. Tariffs diminished impact has been offset by imports, margins, and currency effects.

AI-driven ads reinforce Big Tech's dominance in US ad market
A new analysis from Madison & Wall reveals that Google, Meta, and Amazon captured 56% of U.S. advertising revenue in 2025, up from 53% in 2024, excluding political ads. This concentration is driven largely by the shift towards automated, AI-powered campaign tools like Performance Max, AI Max, and Advantage+, which now account for roughly 12% of US ad spending, projected to rise to 27% by 2030. The trend suggests that AI is not leveling the playing field but rather reinforcing the scale advantages of these incumbents.

Additionally, it cites an IAB report revising US ad growth forecast to 12.3% for 2026.
