Marketing in 2026: The Dawn of Agentic Consumers and the New Rules of Brand Growth

Based on insights from Kantar’s Marketing Trends 2026 report

The marketing landscape in 2026 stands at an inflection point. Artificial intelligence is no longer a supporting technology—it is becoming an autonomous economic actor. According to Kantar’s Marketing Trends 2026, brands will face a dual challenge: winning the hearts of human consumers while optimizing for AI agents that increasingly filter, recommend and influence purchasing decisions at scale.

AI Agents: From Attention to Intention

The most transformative shift identified by Kantar is the rise of AI purchase agents—intelligent systems that consumers brief with intent (“find me mascara,” or “pick the best entertainment service for me”). With 24% of AI users already relying on AI shopping assistants, delegated purchasing is no longer theoretical.

By 2026, consumers won’t just browse—they’ll instruct. Which means CMOs must begin marketing not only to humans, but also to the algorithms acting on their behalf.

This shift gives birth to Generative Engine Optimization (GEO), the new SEO: a discipline dedicated to making brands “machine-legible” so that large language models and agents can understand, rank and recommend them. Kantar notes that three in four AI users rely on AI-driven recommendations weekly, signaling how critical agent-based visibility will become.

In short: if AI doesn’t know your brand, it won’t choose your brand.

Synthetic Data and Augmented Audiences

As marketers face fragmented audiences and diminishing third-party data, synthetic data will play a major role in shaping insights responsibly and at scale. Kantar’s own generative synthetic models now provide 94–95% accuracy vs. ground-truth, enabling marketers to simulate underrepresented or hard-to-reach consumer segments.

In 2026, these capabilities will be paired with digital twins, multimodal AI (text, voice, VR) and real-time modeling—supporting deeper foresight and faster experimentation.

Yet Kantar warns: the industry isn’t fully prepared. Success requires new skills, technical infrastructure, governance and rigorous testing to prevent bias and misuse.

Brand Building in a Machine-Selected World

Technology may recommend, but people still buy—at least for now. That means brands must invest in meaningful difference, the framework Kantar identifies as the core driver of long-term growth.

Attention alone won’t be enough. LLMs elevate brands with:

Clear positioning
Structured, findable information
Distinctive stories
Demonstrated expertise (e.g., recipes, guides, how-to content)

Brands that fail to differentiate risk being “algorithmically optimized out”—excluded from the narratives AI tells.

Creators, Not Just Channels, Drive Effectiveness

Creator content will continue booming: 61% of marketers plan to increase their investment in 2026.

But success hinges on better measurement and tighter strategy. Only 27% of creator content today aligns strongly with a brand’s core story.

Kantar’s guidance is clear: brands must build coherent, long-term creative platforms, not isolated activations, and let creators be creators—providing strategic guardrails without suffocating authenticity.

Retail Media’s Acceleration

With over 200 Retail Media Networks (RMNs) worldwide, retail media has become the most powerful intersection of media and commerce. According to Kantar, RMNs deliver:

1.8× better results than digital ads
3× better performance for purchase intent

Shoppable CTV ads will go mainstream in 2026, merging entertainment, discovery and immediate conversion—further blurring the line between media and the point of sale.

Micro-Communities: The New Social Gravity

As algorithmic feeds favor generic content, consumers are turning to interest-based micro-communities that offer depth, trust and relevance. Kantar reports that brands leveraging knowledge-sharing platforms in China achieved 25% higher ROI, and 40% of consumers trust micro-community recommendations as much as personal ones.

The message is unmistakable: audiences want belonging, not broadcasting.

Treatonomics and Everyday Joy

Despite economic uncertainty, people increasingly seek small, intentional moments of joy. According to Kantar, 36% of consumers are willing to take on short-term debt to treat themselves.

Brands that create accessible, uplifting experiences will win—emotionally and commercially.

The Inclusive Imperative

Finally, inclusion remains a growth driver, not a cultural stance. Kantar’s data shows that 65% of consumers value companies that promote diversity and inclusion, up from 59% in 2021.

Brands must act with authenticity: representation, accessibility and cultural fluency are now business fundamentals.

Marketing in 2026 will be defined by duality: human emotions and machine logic, cultural fluency and algorithmic visibility, broad reach and micro-community depth. Kantar’s analysis makes one thing undeniable: brands that experiment boldly, differentiate meaningfully, and prepare for an agent-first world will define the next decade of growth.
