CEOs are cutting marketing on the theory that AI lets them do more with less. AI made content nearly free, which destroyed output as a measure of value, and the cuts are landing on strategy and brand, not busywork. Australia's ad market is growing 7.4% in 2026, so spending less means ceding ground to competitors who kept the thinking.
When producing a thousand words costs nothing, a thousand words is worth nothing.
The Take: Cheaper output is not more value. AI made producing marketing content nearly free, and plenty of Australian boards have read that as permission to spend less on marketing, when the freed-up hours are worth far more redeployed into judgement than deleted off the payroll. The businesses cutting the thinking work to fund the appearance of efficiency are quietly handing ground to the ones who kept it.
What are CEOs actually cutting when they cut marketing for AI?
75% of chief executives have already cut marketing investment or headcount because of AI, and the reductions reach strategy, research, brand building and planning, not just the admin work most people assume gets automated first.
The assumption is that AI eats the busywork and leaves the brains alone. The evidence points the other way. 75% of CEOs have already reduced marketing investment or headcount because of AI, and the lines being cut include market research, customer relationship building, strategic planning, brand building and positioning work. Those are not clerical functions. That is the part of marketing that decides what to say, to whom and why anyone should care. Handing the production line to a machine and then firing the people who decide what the line should make is a category error, not a saving.
Why cheaper output stopped meaning anything
This is not an efficiency story. It is a measurement story. For a long time, output was a rough proxy for effort and effort was a rough proxy for value. AI snapped that chain in about eighteen months.
Research out of this year's B2BMX makes the point sharply. 71% of B2B firms now use AI mainly to churn out content. A further 56% say its primary value is basic execution. When producing a thousand words costs nothing, a thousand words is worth nothing and the org chart built to reward volume starts measuring the wrong thing entirely.
The trap is right there in the numbers. Firms have automated the cheapest, most commoditised task in marketing and concluded that marketing itself got cheaper. It did not. The scarce thing moved. It moved from making the asset to knowing which asset is worth making.
The market is not shrinking. Budgets are.
Here is the part that should stop a board meeting. Demand is not falling. Australia's advertising market is forecast to grow 7.4% in 2026 to A$31.1 billion, with retail media the fastest-moving channel at 19.5% growth to A$2.3 billion. Across the Australian businesses we have scored at New Rebellion, the pattern is consistent. The ones treating AI as a reason to spend less are not reinvesting the saving into better thinking. They are simply spending less, while their competitors spend more, into a market that is expanding underneath both of them.
Australia's ad market is forecast to grow 7.4% in 2026, the same year many boards are reclassifying marketing as a cost to trim
The two stories only fit together if you accept that cheaper output has been mistaken for a smaller job.
What the AI believers are quietly telling you
If AI genuinely replaced the strategist, the companies betting hardest on it would be staffing up around it. Watch what they do instead. Omnicom offloaded hundreds of the staff who built its AI platform to a third-party contractor. Even the true believers are treating their AI people as a cost line to move off the books, not a capability to build a business around. That tells you how much of this is genuine change and how much is an old-fashioned headcount decision wearing a technology costume.
The strategist did not become redundant. The strategist became the only part of marketing that is hard to copy.
What I would do about it
Count the hours AI actually freed this quarter, then decide where they go before finance decides for you. Left unclaimed, saved time defaults to a budget line, not a better plan.
Redeploy those hours into the work AI cannot do. Positioning. Primary research. Real conversations with real customers. The argument for why anyone should buy from you rather than the cheaper option beside you.
Change what you report. Stop counting assets produced. Start counting decisions improved and demand created. A team measured on volume will keep producing volume long after volume stopped mattering.
If you must cut, cut the volume, not the reasoning. A team that makes fifty average things is easier to replace than one person who knows which five things matter.
Spend into the growth while your competitors retreat from it. A market growing 7.4% with fewer serious operators fighting for it is the cheapest share you will buy for years.
A note on the method. Our reads on the Australian market are directional and Australian-market-specific, built from how we score marketing performance across local businesses rather than from imported benchmarks. You can see the methodology here.
My opinion, stated plainly. AI did not make the strategist redundant. It made the strategist the only part of marketing that is genuinely hard to copy. If AI has handed your team back its hours, the move is to aim those hours at the thinking that grows the business, not to read the saving as proof the thinking was never needed.

Frequently asked questions
Does AI really let you cut marketing headcount?
It lets you cut production time. That is not the same as cutting the people who decide what to produce. The firms cutting hardest are reducing strategy and research, not admin, which is the reverse of what the efficiency story promises.
Is the Australian ad market growing or shrinking in 2026?
Growing. WPP Media forecasts 7.4% growth to A$31.1 billion, led by retail media at 19.5%. Spending less on marketing in a growing market means losing share to competitors who spend more.
What should marketers do with the time AI frees up?
Redeploy it into judgement work. Positioning, primary research, customer conversations and brand. Output is now nearly free, so the value has moved to deciding what is worth making and why.
Why is cheaper content a trap?
Because output stopped being a useful measure of value the moment it became nearly free to produce. When anyone can generate content instantly, volume signals nothing and the advantage shifts to the thinking behind it.
