Three days into Cannes Lions 2026, something interesting is happening. AI is still everywhere, but it is no longer the most interesting conversation.
Instead, discussions across the Palais, the beaches, the publisher houses, and the countless brand activations have shifted toward a much harder question: now that everyone has AI, what actually creates competitive advantage?
That shift was visible throughout Wednesday’s programming, award discussions, and executive conversations, where creativity, measurement, commerce, creator ecosystems, and human connection increasingly dominated the agenda.
Creative Effectiveness Is Overtaking Creative Excellence
For years, Cannes was often criticized for celebrating work that won awards but didn’t necessarily move business metrics.
This year’s festival feels different.
One of the strongest themes emerging from the Croisette is the growing focus on effectiveness, commercial outcomes, and measurable business impact alongside creative ambition. Across discussions around award-winning work, marketers are increasingly asking not just whether a campaign broke through culturally, but whether it drove growth, changed behavior, or created enterprise value.
The implication for brands is significant. The industry appears to be moving beyond the long-running brand-versus-performance debate and toward a more integrated view of marketing effectiveness, where creativity is expected to deliver both cultural relevance and commercial results.
Retail Media’s Evolution Into Commerce Media Accelerates
If there is a business story dominating private conversations in Cannes this week, it is the continued convergence of retail media, commerce, and advertising.
The reported acquisition activity surrounding Vibe.co and Walmart has become one of the most discussed topics among marketers and media executives, not because of the deal itself, but because of what it signals. Retailers increasingly want to own more of the customer journey, from media exposure through transaction, measurement, and loyalty.
What began as retail media is rapidly evolving into a much broader commerce media ecosystem, one that could reshape how marketers think about attribution, customer acquisition, and media investment over the next several years.
Creator Businesses Have Graduated From Channel to Ecosystem
A few years ago, creator marketing occupied a niche corner of the Cannes conversation.
In 2026, creators are sitting much closer to the center.
Throughout Wednesday’s discussions, creators were increasingly discussed not as influencers but as businesses, media properties, distribution channels, and commerce engines. The creator economy is no longer being framed as an emerging opportunity. It is increasingly viewed as a permanent part of the marketing infrastructure.
For agencies and publishers, that distinction matters. The question is no longer whether creators deserve budget. The question is how brands integrate creator-led media into broader marketing and commerce strategies.
The Most Valuable Human Skill Is Becoming Judgment
Perhaps the most interesting shift visible today is the industry’s changing relationship with AI.
Last year, much of Cannes revolved around experimentation and possibility. This year, executives appear far more focused on implementation, governance, and differentiation. AI remains central to almost every conversation, but the emphasis has shifted toward what humans contribute once AI becomes widely accessible.
Across multiple sessions, a common theme emerged: creativity, strategic thinking, taste, and judgment may become more valuable, not less, as AI capabilities become commoditized.
In other words, the conversation is no longer about who has AI. It’s about who knows what to do with it.
The Return of Real-World Networking
Another surprising takeaway from Wednesday is the continued importance of physical events themselves.
For an industry obsessed with digital transformation, the value of in-person connection remains remarkably resilient. Cannes continues to attract more than 13,000 attendees from over 90 countries, and the beaches, terraces, hotels, and side events remain as crowded as ever.
The reason appears increasingly obvious. Trust, partnerships, and major business decisions still happen faster when people meet face-to-face. As automation expands, personal relationships are becoming a greater differentiator rather than a lesser one.
What Marketers Should Take Away
The biggest lesson from Wednesday is that Cannes 2026 feels markedly more mature than recent editions.
The industry is spending less time debating whether AI will change marketing and more time figuring out how to create value in a world where AI is available to everyone. Creativity is being discussed through the lens of effectiveness. Retail media is evolving into commerce media. Creator businesses are becoming permanent infrastructure. Human judgment is emerging as a premium skill.
For marketers, that may be the most important signal coming out of Cannes this year. The winners of the next era are unlikely to be the companies with access to the best tools. They will be the companies that best combine technology, creativity, measurement, and human insight into something competitors cannot easily replicate.
