The marketing agency market is now about $550B worldwide with steady 6–7% CAGR over the last five years.
Growth has been powered by digital ad spending surpassing the $1T mark in 2025 and by clients moving budgets toward measurable, data-driven programs. Industry reports show modest but positive growth for agencies even through volatility.
Large holding companies stabilized with mid-single-digit organic growth while independents gained share in specialist niches. New channels (retail media, creators, streaming video) created incremental demand for managed services.

Which regions are growing the fastest, and why?
Asia-Pacific is expanding the fastest due to ecommerce growth, mobile-first consumers, and platform investment.
The Middle East and Africa also show acceleration with digital infrastructure and creator economies improving. North America remains the largest market by spend, while Europe grows steadily under privacy-compliant ecosystems.
Macro data indicates Asia is set to contribute a majority of global growth, with resilient exports and tech investment supporting advertising demand. Regional forecasts from media buyers show APAC ad markets growing with digital taking the lion’s share.

How are client budgets shifting across traditional, digital, and emerging channels?
Budgets keep moving from traditional to digital, with digital now 60–70% of agency-managed spend.
CMO surveys show overall budgets flat as a share of revenue, but digital lines grow faster within that envelope. Emerging channels—creator programs, retail media, shoppable video—win incremental dollars due to attributed sales impact.
Where brand goals require reach or authority, select TV/OOH remains, but with tighter measurement and MMM/MTA overlays. The direction of travel is consistent across regions.
This is one of the many elements we break down in the marketing agency business plan.

How are AI and automation changing service delivery, costs, and outcomes?
AI is lifting productivity, improving precision, and compressing delivery costs across the agency workflow.
Large networks report AI-linked revenue momentum as clients prioritize personalization at scale; platform partnerships put cutting-edge tools in production. Automated reporting and optimization reallocate human time to strategy and creative direction.
Expect faster testing cycles, more granular audience modeling, and higher creative throughput with similar headcount. Early adopters are winning pitches and expanding scopes by proving ROI uplifts tied to AI workflows.

How are client expectations evolving around measurement, transparency, and ROI?
Clients now expect verified ROI, real-time transparency, and flexible engagement models.
Budget growth concentrates in digital because it is attributable; CMOs keep total budgets flat as a share of revenue, so every dollar must prove its return. Dashboards, clean room reporting, and MMM/MTA convergence are becoming standard.
Agencies that expose fees clearly and commit to outcome-based KPIs win renewals and upsells. AI-enabled insights must be auditable and privacy-safe to pass procurement and legal reviews.
