Cannes Lions 2026: LePub, Ogilvy and Rethink among the major winners
Cannes Lions' 2026 award is an interesting signal for brands: artificial intelligence is both a production tool, a subject of communication and a field of differentiation. Claude's film award allows us to examine how technology becomes an advertising idea.

Watch how a technology becomes a brand promise; then evaluate the results with distinct evidence of the creative reward.
The signal: what is documented
The final Cannes Lions list, announced on June 26, 2026, placed LePub Milan at the top of the Agency of the Year category. Ogilvy is the top of the Network of the Year ranking, and Rethink Toronto is the top of the independent agencies' list. The Grand Prix Film awards two films for Claude directed by Mother London. These are different categories, which must not be merged into a single ranking.
This list offers several reading angles: the performance of an agency, the strength of a network and the execution of a given campaign. For professionals in artificial intelligence and marketing, films for Claude also show that technologies themselves become competitive brands on the creative ground. This observation is an editorial reading, not a judgment of the festival on all tools of artificial intelligence.
Technology not yet making a brand proposal
The films for Claude signed Mother London, distinguished in Lions Film according to the final communiqué, give an example of the positioning expressed by the creation. The teaching we draw from it is not a recipe of tone or humour. A technological brand must choose what it wants to make understand and make it perceptible in a situation. Describe features is not always enough to create a preference.
What one can learn from a Grand Prix
Reading an award-winning case must distinguish between the idea, performance and documented results. A jury's gaze recognizes work in a category and a competitive context. It does not guarantee that the same mechanics would work for another brand or market. The right reflex is to formulate the strategic tension solved by the campaign, then to examine what made its response singular.
The exercise to be conducted in an agency
On a fictitious brief, a team can first write the promise in one sentence, without naming a tool. It then prepares two ways to make it visible, one very demonstrative, the other based on a situation. Artificial intelligence can assist script or storyboard tracks, but the review must judge the sharpness of the idea before the images are finished. This method does not purport to duplicate the work of the rewarded agencies.
Efficiency requires further information
A list is a benchmark for creative recognition, not a complete business record. For a decision to buy or consult, you must ask the context, means and elements of the available results. We therefore separate the officially announced winners from our professional recommendations. Creative lessons are questionable and useful; They must not become invented performance figures.
The point of vigilance
When an agency quotes Cannes, check the edition, the level of distinction, the category and the exact entity rewarded.
