Ad agencies are entering a period of prolonged low growth as the industry continues to adjust to the sweeping impact of artificial intelligence. As reported by The Wall Street Journal, Barclays analysts have lowered growth forecasts for major holding companies, citing both cyclical pressures and long-term structural changes tied to AI adoption.
According to the report, the traditional agency model is under pressure. Advertisers are shifting budgets toward more measurable and efficient digital platforms, and clients are increasingly handling creative and media work in-house. AI is further accelerating this trend by enabling automation across content creation, media buying, and campaign optimization.
Barclays now expects annual revenue growth for major holding groups to average 2 to 3 percent over the next few years, well below the growth levels of the previous decade. This projection reflects what analysts call a “new baseline” as agencies adapt to tighter client spending and rapid technological change.
AI Is Reshaping the Work Itself
While AI brings cost-efficiency opportunities, it also threatens legacy workflows. Many creative processes once done manually, from copywriting to image generation, are now being augmented or replaced by generative tools. Analysts say agencies must rethink their value proposition as clients become more familiar with these technologies and demand leaner operating models.
The shift isn’t entirely negative. AI also presents new revenue opportunities through data-driven services, performance analytics, and faster campaign execution. But it requires agencies to move beyond traditional silos and invest in tech integration, talent retraining, and platform partnerships.
Cost Pressures Meet Cautious Clients
The uncertain global economy adds to the challenge. Clients in sectors like tech and consumer goods are reducing discretionary marketing spend, and procurement teams are placing heavier scrutiny on agency fees. This financial pressure compounds the need for agencies to prove their value and adapt faster than ever.
As reported by The Wall Street Journal, the Barclays note calls this a “slow burn” situation, one where change is gradual but deeply transformative. It suggests that holding companies must streamline operations and diversify service offerings to remain competitive in an industry where AI is becoming a baseline expectation.
What Comes Next for Agencies?
To remain relevant, agencies will need to focus on areas that resist commoditization: strategic planning, brand building, and high-touch creative work that cannot be easily automated. There’s also growing demand for hybrid models that combine human insight with AI-driven efficiencies.
The transformation is already underway, but the coming years will be a test of agility. Agencies that can evolve their models, align with new client expectations, and integrate AI in meaningful ways will have the best chance of weathering the slowdown, and finding growth on the other side.
