Cannes Lions 2026 Predictions
As the digital advertising community prepares for the annual gathering at Cannes Lions in the South of France, it will likely be topics from POSSIBLE Miami that help shape discussions in the Palais. Having recently completed its fourth successful year, the Miami event has now become a firm fixture in the adtech calendar. With a strong presence and participation from senior decision-makers, defined by deals and discussions around adtech innovation, these conversations are set to go deeper in Cannes.
Agentic AI And Human Judgment
We’re in the midst of a transition toward operational AI maturity and a renewed focus on the human elements that must be considered alongside the tech, both for the marketers who use these tools and the consumers they’re targeting. A Salesforce report shows that “AI agents boost ROI as customer expectations outpace marketing execution”.
At Cannes, the agent conversation is likely to continue at pace, as digital advertising moves beyond simple AI assistants toward autonomous agentic AI systems, capable of navigating the multitude of variables in programmatic buying. There will be further exploration around how agentic AI productivity and API reasoning can help manage marketing stack complexity, as the human role moves from manual to one that oversees strategic judgment.
As these agents manage workflows, the key differentiators will be the quality of the data inputs, the governance frameworks in place, and human-led strategies. Expect discussions to focus on balancing automation with human oversight, and a reference to the KPIs that guide autonomous systems to ensure they remain aligned with brand equity.
Rebuilding Trust Through Responsible Innovation
Consumer engagement remains a key goal of advertising, but it is facing combined challenges of ‘Google Zero’ and rising scepticism. AI-powered search is fundamentally reshaping the consumer journey, while negatively impacting publisher traffic. This ‘zero-click’ reality forces a move toward brand visibility within AI answers, rather than simply traditional search clicks.
Simultaneously, there is also a sense of AI ad fatigue among younger consumers, with the IAB finding that: “Gen Z and Millennial consumers feel less positive about AI-generated advertising than ad executives think they do.” Some brands are making a stand against generative AI use in their campaigns, such as Apple and Quip. With Cannes Lions lauded as the ‘International Festival of Creativity’, this will likely be up for further debate at the event, particularly around the award announcements.
There could be questions addressing how organisations are tackling AI fatigue and ensuring technology is used to enhance, rather than replace, creative storytelling. Prepare for conversations about prioritising transparency and emotional resonance, while supporting the wider digital ad industry.
In addition, discussions around the regulation of AI could rise, especially as the US administration is now considering oversight for advanced AI models, according to multiple news reports. The sustainable impact of AI, particularly the energy demands of massive data centres, might also come up: Cannes has been targeted in previous years by Greenpeace stunts.
Solving The Structure Of Retail Media
Retail media continues to be a key driver of growth, yet at POSSIBLE, retailers and marketers raised concerns about the current extent of fragmented networks.
The conversation at Cannes will likely continue to explore answers to the operational silos and inconsistent measurement frameworks that are making cross-channel comparison difficult to manage. There could be a push for standardisation, toward a more unified infrastructure that allows comparable attribution; bringing a collection of individual retail networks into a cohesive media strategy.
Evolution Of The Holdcos
The traditional holding company is undergoing an identity crisis, a topic that was debated in Miami and will continue on the Croisette. There are signs of an increasing divide between the perceived agility of independent players and the legacy structures of industry giants. Independent agencies are celebrated for their neutrality and speed, and this is putting further pressure on the holdcos to prove they are integrated partners rather than collections of specialist shops. At Cannes, there will likely be discussions on whether the traditional model can survive the rise of in-house functions and independents, as their ability to scale today’s technology, and bridge the gap between complex adtech stacks and creative capabilities is questioned.
A Climate Of Caution
Although the industry remains ever innovative, economic caution continues, driven by geopolitical uncertainty and enhanced scrutiny of ROI. There has also been some concern voiced about the impact jet-fuel prices will have on people’s ability to fly to Cannes, and the risk of cancelled flights keeping people grounded this June. With this looming over travel itineraries, there’s a need to be prepared for last-minute changes and back-up plans. The good news is that apparently there won’t be a shortage of super yachts in the Med this summer. The South of France is filling up with boats, and we hope to see you on board there soon.
