Marketing isn't ending. Are marketers? AI and marketing teams in 2026 data
Let me correct one thing up front: I'm not saying "marketing is ending." I'm saying "marketers are ending." I'll make the case with numbers first and predictions second. The CMO awards may not last much longer.
- In Spencer Stuart's survey, 17% of CMOs cut headcount over the past year and 69% kept team size flat while shifting capabilities to AI. 36% expect cuts in the next 12–24 months.
- According to The CMO Survey 2026, US marketing team growth fell to 2.5%, down from 5.4% the year before.
- Performance marketing already belongs to AI. Brand work still needs people today, but that edge won't last.
What does the research say about marketing teams?
1. Spencer Stuart CMO survey (December 2025). Over the past 12 months, 17% of CMOs reduced headcount because of AI. Only a few added people. The striking number is this: 69% kept headcount flat but shifted their team's capabilities toward AI. For the next 12–24 months, 36% expect to reduce headcount.
The key point: even companies with healthy, growing financials are shrinking marketing teams or not opening new roles.
2. The CMO Survey 2026 (Duke, Deloitte, AMA). US marketing organizations grew by an average of 2.5% over the past year, down from 5.4% the year before. The median is zero: most companies aren't growing marketing at all.
3. McKinsey, The state of AI (2026). In 2025, 32% of respondents expected AI-driven headcount reductions; a year later, 14% had actually cut. This covers whole companies, not just marketing, but it shows the direction: the forecasts haven't fully arrived, yet the cuts have started.

What does AI deliver in performance marketing?
In planning, content production and feedback loops, AI is already taking over responsibilities that used to sit with performance teams.
- Campaign automation: According to Bizcommunity's report on WARC data, brands using Meta's Advantage+ saw 41% higher blended ROAS and 17% lower new customer acquisition cost than with manual campaigns.
- Bidding: Google says Smart Bidding performance depends on the volume and quality of conversion data in the account. Companies with clean data win by handing bidding to AI.
- Creative: In Digital Applied's analysis of more than 50,000 ad variations, AI creatives on Meta earned 12% higher CTR (1.08% vs 0.96%). Teams report saving 20+ hours a week.
In short, performance marketing is by nature in the middle of an AI transformation.
Are brand teams safe from AI?
On the brand side, AI is strongest in the "input and execution" layer and weakest in the "meaning and decision" layer. But brand teams can't breathe easy yet.
Where AI is strong: listening and insight, breadth of content (names, slogans, visuals), consistency and, most critically, fast pre-testing.
Where it falls short: original perspective, cultural timing and intuition, knowing what not to say, accountability, and measuring long-term impact.
You'll say, "See, you can't build a brand without people." Today, I agree. For the near future, I can't say the same.
What's next for brand teams?
- No one coming up from below. Most entry-level work is now handled by AI, so fewer new marketers will be trained and human insight will thin out.
- Experience will matter less. Today's large language models work on prediction. Newer models are moving toward insight, understanding and interpreting the world, which erodes the brand team's experience advantage.
- Agents will decide. To me this is the biggest one. When AI agents rather than people make purchase decisions, communication between agents (A2A) will run on efficiency. That favors effective, sales-oriented communication over brand positioning; in other words, performance marketing. Which brings us back to the numbers at the start.
- "Which product" over "which brand". For people, the question may shift from "which brand" to "which product is most efficient for me." That reduces the human touch.
Bottom line: the CMO awards may be in trouble
If the game stays on the brand side, AI is starting to learn emotions too. If it shifts to efficiency, AI is already there. Either way, the CMO awards may have a problem.
That's why we built SIEMO: finding customers and making first contact is now a system's job, not a team's. I wrote about the bigger picture in Find, call, build.
