IAB Updates Its 2026 Outlook with New Advertising Market Signals

What happened

The September review updates expectations and identifies changes in momentum across advertising channels.

What changes

Ad inventory, data, creative work and measurement need to be considered together rather than evaluating the format in isolation.

Why it matters

Connecting creative work and media spending to business outcomes is more useful than optimizing intermediate metrics alone.

Implications for businesses

A U.S. advertiser can compare the revised outlook with its current channel performance and adjust tests before changing the full media plan.

Un Rino’s take

Creativity remains essential. Measurement should help explain what changed for the business, not simply produce more platform statistics.
