Client-Side Marketing In-Housing Trend Statistics 2026

Quick answer

The ANA’s 2026 State of In-Housing report, surveying 404 jurors from its In-House Excellence Awards, found 35% agree marketers are in-housing more than ever against just 7% who see work moving back to outside agencies, and 34% observed in-house teams expanding their scope of work against 7% who saw the reverse. Cost savings as the top-cited reason for in-housing dropped sharply, from 30% in 2023 to just 9% in 2026, while 53% now expect an in-house team to deliver strategic, big-idea creative work, not just cheaper production.

A prior wave of the same ANA survey put member in-housing prevalence at 82% in 2023, up from 78% in 2018, 58% in 2013, and 42% in 2008, a historical trendline reported across industry trade coverage of the study rather than independently re-fetched from ANA’s own site this research cycle.

What the ANA’s 2026 Jurors Reported

The Association of National Advertisers ran its 2026 State of In-Housing survey among 404 jurors of its own In-House Excellence Awards, a pool the report describes as brandside marketers, agency professionals, and independent consultants with direct, day-to-day experience running or partnering with in-house teams. Their answers point the same direction on two separate questions: 35% agree that marketers are in-housing more than ever, against only 7% who believe the pendulum is swinging back toward outside agencies, and 34% observed in-house agencies expanding their scope of work, against 7% who saw work moving the other way, back out to external shops.

The functions most commonly pulled in-house, per the same report: social media (58%), influencer and creator marketing (37%), and SEO (35%). Among US-based in-house teams specifically, media now runs at 67%, the highest single function measured.

Why Cost Savings Stopped Being the Reason

What changed is not just how much work moves in-house, but why a company says it made that call. Cost savings, the reason usually assumed to be driving in-housing, fell from 30% of respondents citing it in 2023 to just 9% in 2026. In its place, 53% of respondents now expect an in-house team to deliver big creative ideas at a strategic level, not simply execute production work more cheaply than an outside agency would.

A prior wave of the same ANA survey put member in-housing prevalence at 82% in 2023, up from 78% in 2018, 58% in 2013, and 42% in 2008, since the ANA has run some version of this study every five years going back to 2008. That historical trendline is reported across multiple pieces of industry trade coverage of the study rather than independently re-fetched from ANA’s own site this research cycle, so treat the specific percentages as well corroborated but not freshly re-verified.

Is cost savings still the main reason companies build an in-house team?

How much has in-housing grown since the ANA started tracking it?
A prior wave of the same survey put member in-housing prevalence at 82% in 2023, up from 78% in 2018, 58% in 2013, and 42% in 2008. That historical figure is corroborated across industry trade coverage of the study rather than independently re-verified against ANA’s own site this research cycle.
