U.S. advertising is entering 2026 with stronger momentum than expected, but the recovery is changing what media buyers consider valuable. The Interactive Advertising Bureau (IAB) has raised its full-year U.S. ad spend growth forecast to 12.3%, up from 9.5% in January, while advertisers increasingly prioritize customer acquisition, CTV, commerce media, contextual targeting and visibility inside AI-driven discovery environments.
The Interactive Advertising Bureau has raised its forecast for U.S. advertising growth in 2026, pointing to stronger first-half spending, major live events and growing advertiser confidence despite continued economic uncertainty.
The revised 12.3% growth forecast represents a 2.8-percentage-point increase from the organization’s January projection. The latest outlook is based on input from more than 200 brand and agency advertising decision-makers.
The upgrade comes as advertisers reassess where consumers discover products and how media performance should be measured. The IAB says customer acquisition is now the leading media investment goal for 63% of buyers, up nine percentage points since January, while brand equity rose six points to 43%.
That shift matters because the advertising market is becoming more fragmented. Consumers increasingly move between social platforms, commerce marketplaces, search engines, streaming services and AI assistants before making a purchase.
For media buyers, the challenge is no longer simply reaching a large audience. It is determining which signals indicate that a consumer is actually moving toward a purchase.
AI is becoming part of that equation.
According to the IAB study, adapting to AI-driven search and changing consumer behavior is the leading media investment challenge, cited by 44% of buyers. Another 38% identified low-quality AI-generated content, or “AI slop,” as a concern.
At the same time, 76% of buyers say optimizing content for AI-generated answers is an area of increased focus, while 72% are increasing their focus on large language model platforms.
That represents an important change for advertising technology. AI is not simply being deployed inside campaign management platforms to automate bidding, targeting or creative. Increasingly, advertisers are trying to understand how brands appear inside AI-mediated discovery itself.
The measurement implications are significant. The IAB says 86% of buyers are changing, or expect to change, how they measure media performance over the next 12 months because of conversational AI tools and AI agents.
Nearly half of buyers, 48%, are looking at brand visibility and citations inside AI tools as a measurement approach. Others are monitoring branded search, direct traffic, third-party AI discovery tools, AI-platform referrals and incrementality.
This creates a new layer of media measurement alongside conventional metrics such as impressions, reach, clicks, conversions and return on ad spend.
The channel-level outlook also favors digital advertising.
Social media is projected to grow 16.5%, followed by CTV at 15.6% and commerce media at 13.6%. Digital video excluding CTV is forecast to increase 9.4%, while podcasts are expected to grow 8.7%.
By comparison, linear TV is projected to decline 1.5%.
The trajectory is consistent with the broader digital advertising market. IAB/PwC reported that U.S. digital advertising revenue reached nearly $300 billion in 2025, growing 13.9% year over year.
Digital video is also becoming a larger component of that market. IAB projects U.S. digital video advertising will surpass $80 billion in 2026, with CTV, social video and online video all contributing to growth.
The latest outlook points toward an increasingly diverse advertising stack. Buyers say creator and influencer advertising, cohort-based targeting, publisher first-party data and contextual advertising are among the areas receiving greater attention.
For technology vendors, that creates opportunities across the programmatic ecosystem. DSPs, SSPs, CTV platforms, retail media networks, data providers and measurement companies will increasingly need to connect fragmented signals without sacrificing transparency or privacy.
The competitive landscape spans major platforms such as Google, Amazon, Microsoft, Meta and Adobe, alongside independent advertising technology companies and specialized CTV, commerce media and identity vendors.
For enterprise advertising teams, the message is straightforward: media planning is becoming less about selecting individual channels and more about building systems that can recognize consumers across fragmented discovery environments.
The next phase of advertising technology may therefore be defined by two questions: where did the consumer discover the brand, and can that influence be measured?
The IAB’s latest forecast suggests advertisers are prepared to keep increasing budgets. The harder task will be proving where those dollars actually create incremental value.
Market Landscape
The U.S. advertising market is increasingly shifting toward digital environments where audiences can be targeted, measured and optimized across multiple touchpoints.
The IAB’s January 2026 outlook originally projected 9.5% overall ad-spend growth, with CTV at 13.8%, social at 14.6% and commerce media at 12.1%. The September update’s higher projections indicate that buyer sentiment and spending momentum have strengthened.
CTV is particularly important because it combines television-scale reach with digital advertising infrastructure. IAB’s latest digital-video research expects digital video spending to surpass $80 billion in 2026 and says digital video will exceed 60% of total TV/video advertising spend for the first time.
At the same time, AI is creating a new discovery layer. Advertisers now have to account for consumers asking AI assistants about products and brands, while measurement vendors work to determine how those interactions should be incorporated into media attribution.
That puts pressure on traditional advertising infrastructure. Audience identity, contextual signals, first-party data, AI visibility, incrementality testing and cross-channel measurement are increasingly interconnected rather than separate functions.
