Key stat: Only 30% of ad industry professionals have fully-scaled AI across their media campaign cycles, according to January data from the Interactive Advertising Bureau (IAB).

Beyond the chart:

• Identifying/segmenting audiences is the top use case of AI for agencies and brands, while publishers are using AI for inventory prediction and forecasting, per IAB.
• The two biggest barriers to AI adoption for both buy- and sell-side parties are the complexity of setup/maintenance and data security risks, cited as a significant or critical concern by 62% of ad professionals.

Use this chart: Marketers should assess their AI maturity level relative to industry peers—especially if you're at a brand. Agencies and publishers are accelerating adoption, which means partners and competitors may already be using AI to optimize spend and performance.
