How Fast Is the Marketing Agency Model Actually Shrinking? What the 2026 Numbers Say

If you run a small business, you have probably read two opposite stories this year. One says AI is about to wipe out marketing agencies. The other says agencies are fine and the AI talk is hype. Both are selling something, and neither shows its working.

So this piece looks only at numbers anyone can check — the US government’s monthly job counts, the biggest annual survey of marketing budgets, and the published results of the largest agency groups. Taken together, the marketing agency industry trends they show are clear enough to plan around, whether you hire agencies or run one.

Is the marketing agency industry actually shrinking?

Yes — by jobs, the US agency industry is smaller than it was three years ago, even as the wider economy has kept adding work. The US Bureau of Labor Statistics counts payroll jobs every month, and two of its series cover agencies directly.

The broader advertising and PR group is now below where it stood in January 2020 (488,000), before the pandemic. Agencies themselves have lost more than one job in ten. Over the same stretch, lawyers, accountants, consultants and engineers — the rest of professional services — grew slightly.

How fast is it happening?

About 3–4% of US ad-agency jobs a year since the spring of 2023 — and the steepest year so far was 2024, not 2026. Year by year, the advertising agencies series fell:

• 2024: −5.5% — from 223,300 in December 2023 to 211,000 in December 2024.
• 2025: −2.1% — to 206,500 by December 2025.
• 2026 so far: −2.3% — to 201,800 in July (preliminary).

That is a real decline, but it is a slope, not a cliff. To picture it: an agency with 20 people in 2023 that shrank at the industry’s rate would have 17 or 18 today. Not an implosion — just desks that were never filled again.

The forecasts are running ahead of the count

In June 2023, Forrester forecast that US agencies would lose 32,000 jobs to automation by 2030 — 7.5% of the workforce. The broader BLS series has already lost 27,200 since its 2023 peak, so by that measure the 2030 number is most of the way there four years early (though BLS says how many jobs went, not why).

In October 2025 Forrester went much further, predicting that 15% of agency jobs would go in 2026, as reported by The Drum. The official US count shows nothing like that yet: the broader advertising and PR group is down 1.2% between December 2025 and August 2026. Part of the gap is scope — a forecast about big agency networks is not the same as a count of every US agency down to the two-person shop — and announced cuts take months to show up in payroll data. But anyone quoting “15% of agencies gone this year” as fact is quoting a prediction.

Why are marketing agencies losing ground?

Because the clients paying them have flat budgets and a new option for routine work. Gartner’s 2025 CMO Spend Survey of 402 marketing leaders found:

• Budgets have stopped growing — marketing budgets averaged 7.7% of company revenue, flat on the year before and, as Chief Marketer reported from the same survey, down from 9.5% three years earlier.
• Agencies are the first line cut — 39% of CMOs planned to cut agency budgets, mainly by dropping unproductive agency relationships and shrinking their agency rosters.
• AI is replacing some agency work — 22% said generative AI had let them rely less on outside agencies for creative work and strategy.

Note who answered: mostly companies with more than $1 billion in revenue, in North America and Europe. Small businesses were not surveyed — but the same pressure reaches them, because the big clients’ decisions set the headcount of the agencies small businesses hire.

The jobs going first are the routine ones

Forrester’s 2023 forecast named which agency roles automation hits hardest: clerical roles (28% of expected job losses), sales roles (22%) and market research roles (18%). It expected jobs in management, creative, public relations and data to grow as a share of agency staff. In its words, “the more creative and ‘original’ the agency role, the less likely it will be replaced by automation.”

That fits the rest of the evidence. The work being squeezed is the production layer — resizing, first drafts, reporting, desk research — which is exactly the work agencies used to staff with juniors and bill by the hour.

Are big agencies and small agencies moving the same way?

No — the agency world is splitting, and the averages hide it. At the top, the large holding groups posted very different 2025 results:

So even among the giants, one is shrinking, one is growing, and one is merging and cutting. “Agencies are dying” is too simple. The pattern is that agencies selling hours are shrinking, and agencies selling results with fewer people are holding up.

At the small end the same split plays out on a smaller scale. A boutique agency that still bills a junior’s time for resizing banners is competing with software. One that sells judgment — the strategy, the idea, the relationship — and uses AI for the production underneath can serve more clients with the same team. We covered how that works in practice in how agencies use AI tools to scale.

"Agencies selling hours are shrinking, and agencies selling results with fewer people are holding up."

What do marketing agency industry trends mean for a small business?

If you pay an agency or are about to hire one, these trends change what a fair deal looks like. Four practical points:

1. 01.Ask what the retainer pays for — if a big share is production (resizing, first drafts, monthly reports), that work now takes a fraction of the time it did in 2023. It is reasonable to ask whether the price reflects that.
2. 02.Buy judgment, not volume — the part of an agency worth paying for is the part Forrester expects to survive: strategy, the creative idea, and someone who knows your market. Pay for that; keep the routine output in-house.
3. 03.Prefer projects to open-ended retainers — with budgets flat and agency rosters shrinking, clients are moving to defined pieces of work. A small business can do the same: a positioning project, a launch plan, a campaign idea.
4. 04.Check the real cost of doing it yourself — the comparison is not agency vs nothing. It is agency vs your time plus tools. Our agency vs AI platform cost comparison runs those numbers.

The honest caveat: an agency is still the right call for some businesses. If you need someone to run your ad accounts day to day, manage a media budget, handle PR relationships or be accountable for results, software does not replace that. TurboAgents makes the marketing work — research, strategy, content, creative — it doesn’t publish it, buy the media or measure it.

What this means if you run a small agency

The numbers say the hours-based model is the one losing ground, so the question for a boutique agency is what it sells instead. Three moves the data supports:

• Move your people up to strategy and ideas — the roles Forrester expects to grow. Let tools do the first draft of the market research and the brief, and spend your team’s time on the call.
• Stop re-explaining each client — much of an agency’s hidden cost is re-briefing every tool and freelancer on every client. TurboAgents Brand Brain reads a client’s website once, you confirm what it found, and nearly thirty tools start from those facts after that.
• Turn repeat jobs into a set process — the monthly research, brief and content run that every client gets can be drawn once in the Workflow Builder, where each step is handed the full work of the steps before it, and run again next month.
• Prove results you actually got — as clients cut rosters, the agencies that stay are the ones that can show outcomes. The Case Study Writer turns a real client result into a client-ready case study using only the numbers you enter, with a marked space for a real client quote instead of a made-up one.

Who this doesn’t suit: agencies that need multi-user seats, approval chains or a client portal. Every TurboAgents plan is single-seat, and the Agency plan ($999 a month) is sold through the sales team rather than self-serve.

TurboAgents sells an AI marketing platform, so we are not neutral on this topic — which is why every figure above links to a source you can check yourself.

If the numbers have you rethinking what to pay an agency for, start with the part agencies charge most for and software now does well: the research and the brief. Run a Market Analysis on your category, then turn it into one clear page with the Strategy & Brief Creator — whether you hand that brief to an agency or work from it yourself.

Start a free 2-day trial — no credit card required — and see how far your own research and brief get you before you sign the next retainer.
