More than 80% of marketing AI pilots are being funded by reallocating existing marketing budget rather than through additional investment, raising questions over whether companies are building AI capability by cutting into core brand, customer, and performance activity.
Research from The Future Works, reported by Marketing Week, found that 84% of marketing teams are “cannibalising” their own budgets to pay for AI investments. The finding suggests that AI experimentation is moving quickly, but not always with clear board-level funding, measurement, or investment discipline.
Budget pressure has intensified as marketers are expected to use AI across creative production, customer insight, content generation, audience segmentation, media optimisation, and reporting. In many organisations, AI adoption is being treated as a productivity opportunity before a dedicated financial model has been agreed.
That creates a management tension. If AI pilots are funded by cutting other marketing activity, experimentation may come at the expense of brand investment, campaign reach, agency support, or customer research. Productivity gains can also be assumed before workflows have been redesigned and tested.
The funding problem sits alongside a wider capability challenge. Public policy is already linking AI adoption with workforce skills, while separate CIM research has found that many marketing teams are using AI without a defined skills strategy. Budget, governance, and capability are increasingly inseparable.
Marketing has long faced pressure to justify activity that does not map neatly to immediate sales attribution. AI could intensify that pressure. Tools promising faster production, lower content costs, and more efficient targeting may encourage finance teams to view marketing as a function capable of absorbing greater demand without greater investment.
Well-chosen pilots can still reveal where automation reduces manual work, improves targeting, or accelerates insight. Problems emerge when pilots multiply without a clear view of what they replace, what they cost, and what return they are expected to produce.
Marketing leaders need stronger financial governance around AI adoption. Separate experimentation budgets, agreed success metrics, and post-pilot reviews can help distinguish real efficiency from budget displacement. A tool that reduces agency spend but increases internal review time may not deliver the productivity improvement suggested on a procurement spreadsheet.
The agency market will feel the pressure as brands redirect existing spend. Clients may reduce external budgets while expecting agencies to bring new tools, skills, and faster delivery. Agencies will need to demonstrate value in areas AI cannot easily replace: strategic judgement, creative direction, brand stewardship, regulatory understanding, and cross-channel orchestration.
Customer risk also rises when AI investment is funded by reducing human review or research. The more content and personalisation companies produce, the more guardrails they need around accuracy, privacy, tone, claims, and brand consistency. AI may lower production costs, but accountability remains with the organisation using it.
The budget squeeze also exposes a board-level investment question. If AI is expected to change customer acquisition, retention, brand visibility, search, content, and customer service, it cannot remain a discretionary experiment hidden inside existing marketing lines. It becomes a strategic capability requiring investment, skills, risk controls, and operating-model change.
Companies that treat AI pilots as investment decisions rather than budget workarounds will have a clearer path. That means deciding what the technology is expected to improve, how benefits will be measured, and which existing activities can safely be reduced without weakening long-term growth.
