Cannes Lions 2026 has put two subjects above all others on its program: creators and artificial intelligence. That is the headline finding from eMarketer's coverage of this year's festival, and it marks the clearest signal yet of where the advertising industry's attention — and budgets — are heading.

No fringe sideshows this year. The creator economy and AI moved to the center stage of the industry's most watched gathering, according to the report.

What does the program signal?

Festival lineups function as a lagging indicator of where marketing money actually flows. When AI and creator partnerships dominate the agenda at Cannes Lions, it means brands, agencies, and platforms have already committed real spending to both.

For operators in martech and adtech, the takeaway is practical. Creator marketing and AI-driven campaign tools are no longer experimental line items — the industry's flagship event treats them as core infrastructure.

Who should care?

• Brands and agencies recalibrating media mix toward creator-led campaigns
• Martech vendors building AI tools that now have mainstream buyer attention
• Publishers and platforms competing for creator budgets
• Analysts tracking the shift from traditional channels to creator and AI-driven formats

Why Cannes Lions still matters

Cannes Lions remains the advertising industry's premier festival, drawing global brands, holding companies, and tech platforms each June on the French Riviera. The themes that headline its stages tend to define procurement priorities for the following twelve months.

This year, that spotlight belongs squarely to creators and AI. eMarketer's reporting frames both as the defining threads of the 2026 edition.

Watch for follow-through: budget allocations, vendor announcements, and platform deals announced around the festival typically surface in earnings calls and product releases through the rest of the year.
