Ten Conclusions From Cannes Lions Festival 2026

What the festival says about where the industry is heading and what’s being left behind

Five days covering official and partner events at Cannes Lions, a press room filled with conversations, and parties every night with some serious contrarian beliefs. This is my download from the world’s biggest marketing, advertising, and tech event.

1. AI is the plumbing, not the pitch

The debate about whether AI would change creative work is over. At Cannes 2026 it was barely a question: AI is embedded in production at every serious agency and brand, and executives still framing it as an emerging opportunity are already behind. The conversations are about governance, quality control, and differentiation at a moment when everyone has access to the same models. Capability is table stakes. What you do with it is the competitive variable.

2. The next sale might be made by an agent

AI agents are moving up the consumer journey, filtering options, synthesising research, and making recommendations on behalf of users. As this behaviour scales, the question of how brands position themselves to machine reasoning as well as the human psychology becomes commercially significant. A creative strategy built for emotional resonance may perform entirely differently when the first decision in the chain is made by an AI agent. Nobody has solved this, but the agencies starting to work on it now will be in a materially different position from those that wait.

3. The creator economy has outgrown the footnote

Ten years ago, a young person with creative ambitions would have aimed for a junior role at a production company or agency. That same person today is more likely building their own brand, contracting directly with clients, and outearning a peer in a holding company by year two. This is not a content management challenge. It is a structural shift in where creative talent goes, how it is commissioned, and what brands are competing for when they want to reach audiences. The creator economy is not adjacent to the marketing ecosystem. For many brands, it is the marketing ecosystem.

4. Social has closed the funnel

The platform companies spent years trying to close the loop between discovery and purchase. It is closed. Social has become a retail environment, and the brands performing best on it have stopped pretending otherwise. The awareness-consideration-conversion model assumes a journey that no longer describes how a growing share of purchases actually happen. People see, want, and buy without leaving the app. Media planning that still treats social primarily as a brand-building channel is working from the wrong map.

5. Sport is running the playbook everyone else needs

Some of the most strategically useful sessions at the festival were in the LIONS Sport programme, which would not previously have been the obvious place to look for insight. The sports industry has built mechanics for fan engagement, long-term loyalty, and direct audience monetisation that most consumer brands have not come close to replicating. It has also moved faster on data and personalisation than most of the advertising sector. Marketers looking for models that work outside their own category are not spending enough time there.

6. Martech complexity has passed the point of manageable

The technology landscape for advertising and marketing is more complex than at any previous point and it is not stabilising. Synthetic personas, deep behavioural analytics, AI-driven segmentation: these are available now, not hypothetical. The problem is that most teams cannot deploy them effectively. The gap between what the tools can do and what organisations extract from them is widening. That gap is where competitive advantage is currently being conceded.

7. The big three have a ceiling, and premium print is above it

Alphabet, Meta, and Amazon remain dominant. There is no credible near-term challenge to that. But the working assumption that these three platforms are sufficient has started to erode. Inventory saturation, algorithmic unpredictability, and renewed interest in brand-building as a discipline distinct from performance marketing have created genuine space for other channels. Premium print was discussed more seriously at Cannes than it has been in years: not as nostalgia, but as a high-attention, high-trust environment that reaches audiences the platforms cannot reliably supply.

8. Nobody has a replacement for the agency billing model

The time-and-materials structure on which most agency-client relationships are built does not survive the AI transition intact. Work that previously required a month can be done in a week. Clients know this. Agencies know clients know this. What nobody has agreed is what comes next. Outcome-based fees, IP licensing, subscription retainers: all were proposed during the festival, none adopted at scale. Agencies are confronting the same structural problem consultancies are starting to face. The business is built on charging for time and expertise. AI compresses both. There is no clean answer, which is why nobody offered one.

9. Data privacy has become a commercial argument

Regulatory pressure on data handling is not new. What has shifted is how some organisations are framing it: not as a compliance cost but as a differentiator. In financial services, healthcare, and premium publishing, demonstrable privacy practice is beginning to feature in purchasing decisions. The brands that build privacy into the product, and tell customers so, are starting to see the payoff in their numbers.

10. The agency market has fewer real choices than it looks

The Omnicom acquisition of IPG created the world’s largest marketing services group. WPP has had a difficult run. The practical effect is that the number of genuinely independent, large-scale agency options available to major clients has contracted. At Cannes, holding company executives made the case for scale. The harder questions, about conflict management, talent spread across competing accounts, and what consolidation means for the client in the room, were asked more quietly. For mid-market clients in particular, the leverage position is not what it was two years ago.
