Correction, 2026-10-02: we rechecked every winner, quote and rule on this page against Cannes Lions and the trade press. The opening still said Claude won two Film Grand Prix; it won one, shared by two films. We quoted the Design jury president as calling Apple's work "gloriously handmade"; he said "gloriously human-made". The juror quotes were presented as post-festival comments from jury presidents: they come from three jurors (one of them a jury president) interviewed by Social Samosa in May 2026, before judging, and we had merged two of Rakesh Menon's sentences into one. We wrote that no 2026 jury rewarded AI-made work and that the other Grand Prix winners won "rather than automation"; in fact the Digital Craft and Creative Commerce Grand Prix went to work built on AI, so we removed both claims. We called the Claude films "conventionally produced" with a "human" craft and idea; the entrants' own description says the AI characters' lines were built from a rival chatbot's answers, so we now describe the production from that source. The rules list mixed the measures announced in 2025 with the 2026 Integrity Standards and presented AI disclosure as new (the question has been mandatory since 2024). We removed the figure of twelve DM9 awards (sources disagree), the "most talked-about" and "tightest-ever" labels, and other claims we could not source.
Correction, 2026-09-30: we said Claude's campaign won two Film Grand Prix. Cannes Lions awarded one Film Grand Prix, shared by two of the campaign's films. Fixed.
The most visible AI result at Cannes Lions 2026 was an ad about AI. The Film Grand Prix went to two of Anthropic's Super Bowl LX films for Claude, by Mother London, which imagine AI assistant conversations interrupted by advertising. Adweek's headline called it a campaign "mocking AI ads". But AI also sat inside the work in other categories: the Digital Craft Grand Prix went to Google's "Project Genie", an application of the Genie 3 model, and the Creative Commerce Grand Prix to what Cannes calls "an AI-driven tool". The festival added AI Craft subcategories and ran its first year under new Awards Integrity Standards. This page sticks to what Cannes, the winning entrants and the trade press have published, with sources at the end.
TL;DR
- Claude's Super Bowl campaign won the Film Grand Prix, awarded jointly to two of its films, by Mother London. Adweek reports it also won Gold and Silver Lions in Film and a Silver Lion in Creative Strategy.
- AI-built work won Grand Prix too: "Project Genie" for Google in Digital Craft, and "Lucky Fan Index" for Wisła Kraków by VML Warsaw in Creative Commerce.
- AI Craft subcategories were introduced across the craft-led Lions, to recognise work where human creativity and AI together create ideas "that neither could achieve alone" (Cannes Lions).
- Entry rules tightened after the 2025 DM9 scandal: sign-off on factual accuracy from entrant CEOs and brand CMOs, AI-assisted checks of entry claims, an independent Integrity Council, and, per Adweek, bans of up to three years for deliberately misleading work. The AI disclosure question has been mandatory since 2024.
- Our read for brand teams: AI makes execution cheaper, so the idea and the finish carry more of the weight. Plan your AI-use record from the first frame, because Cannes asks about it.
The result that framed the week
Cannes Lions awarded the Film Grand Prix to two campaign films, "Can I Get a Six Pack Quickly?" and "How Can I Communicate Better with My Mom?", for Claude, by Mother London. Cannes describes them as "darkly comedic Super Bowl films" that "positioned Claude as the AI pledging not to run commercial messages on its tools". Adweek reports the work also picked up Gold and Silver Lions in Film and a Silver Lion in Creative Strategy, and that it was "a favorite among creative leaders going into Cannes Lions". The films were directed by Jeff Low through Biscuit Filmworks.
The Film jury president, Pelle Sjoenell, explained the choice in Cannes' announcement: "An ad about where ads shouldn't exist. An AI making fun of AI. A challenger that took on the market leader, using its own announcement against it, like corporate aikido, with wit, nerve and craft in every frame."
How it was made matters for this page's question. The entrants' own One Show 2026 entry credits a director, a director of photography and a casting director, and says the AI characters were played by performers briefed "using hours of competitor chatbot audio". It also says the dialogue was built "directly from the responses of a competitor's LLM after asking the exact questions a human character would". So the winning film was shot with a cast and crew, AI was its subject, and a rival model's real answers supplied its script material.
The other Grand Prix show AI on both sides of the line. Apple's "Apple TV Rebrand", by TBWA\Media Arts Lab, Los Angeles with Apple, took the Design Grand Prix, and the Design jury president, Greg Quinton, said: "We awarded the Grand Prix because it's gloriously human-made." AXA France's "Three Words", by Publicis Conseil, Paris, took the Creative Effectiveness Grand Prix for adding a three-word clause for domestic abuse sufferers to its home insurance contracts. At the same time, Google's "Project Genie", which Cannes calls "a first-of-its-kind application of the Genie 3 model", won the Digital Craft Grand Prix, and VML Warsaw's "Lucky Fan Index" for Wisła Kraków, "an AI-driven tool" in Cannes' words, won the Creative Commerce Grand Prix. The Innovation jury president, Kazuhiro Shimura, summed up one view: "In the age of AI, creating is easier than ever, but creating change is not."
What the jurors said before judging
In May 2026, before the festival, Social Samosa asked several 2026 jurors about the new AI Craft subcategories. Lines from three of them:
Rakesh Menon, a juror for Creative Business Transformation, framed the craft question directly: "Craft is not a layer you put on top; it has to be built into the idea itself." On AI's role: "AI will always be a tool that can help enhance or even enable the idea." And: "Creativity feeds off instinct. And instinct is earned, not generated."
Gurbaksh Singh, a juror for Digital Craft, made the point that AI-versus-human is the wrong axis: "The strongest work does not feel AI-made or human-made. It simply feels thoughtful, original, and relevant." Kainaz Karmakar, Health & Wellness jury president, described the AI Craft subcategories as "an opportunity to display how you can elevate the use of this tool to create something awe-worthy," and said human creativity "is always in a state of divine discontent."
Read together, these are not anti-AI statements. Our reading is that they describe a bar: generative tools remove the excuse that something was too expensive or too slow to make, which puts more of the weight on insight, taste and intention.
The rule changes behind the scenes
The trigger was the 2025 DM9 case. DM9's Creative Data Grand Prix for "Efficient Way to Pay", for Whirlpool's Consul brand, was withdrawn after Cannes Lions said the case study included AI-generated and manipulated content used "to simulate real-world events and campaign outcomes". The Drum reports that one segment used altered CNN Brasil footage, modified to look as if it covered the campaign, and that CNN Brasil filed a formal complaint. DM9 also withdrew "Plastic Blood" for OKA Biotech and "Gold = Death" for Urihi Yanomami, and Cannes Lions confirmed that all awards connected to the three entries would be withdrawn.
In its 2025 statement, as reported by The Drum, Cannes announced a revised Code of Conduct for entrants, mandatory disclosure of AI use in entry materials (failure to disclose leading to disqualification or withdrawal), content detection tools, and an adjudication committee with expertise in AI, ethics and content integrity. For 2026 these were formalised as the Awards Integrity Standards:
- Sourced claims and senior sign-off. Sources for claims are requested at entry, entrants must provide proof of impact, and declarations of factual accuracy go up from entrant CEOs and brand CMOs to network CEOs.
- AI disclosure. Per the LIONS Integrity Handbook, the AI disclosure question has been mandatory since 2024. It asks which tools were used, the extent of AI in the final work, the data sources behind AI-generated elements, and how results were verified. Presenting AI-generated work as entirely human-created is not allowed.
- Checks. Cannes uses "a bespoke internal AI model" to verify information in entries, and jurors can raise questions about an entry at each stage of judging.
- Consequences. Violations can mean disqualification, withdrawal of awards, exclusion from juries or a ban from future festivals, with escalated cases reviewed by an independent Integrity Council. Adweek reported that agencies found to have submitted deliberately misleading work may face a ban of up to three years.
Cannes published the Integrity Handbook in November 2025, and Adweek reports it also hosted webinars and set up a dedicated support team for entrants. The structural change worth noting for creative planning is the AI Craft subcategories inside the craft-led Lions. Cannes says the focus is on "genuine craft, artistry and intent, where AI works in service of the idea."
What this means for brand teams
Three practical takeaways if you are planning campaigns or award entries for the next cycle.
Put the effort into the idea. When execution gets cheaper, the differentiator moves upstream to strategy and insight. If you are using AI to make more of the same work faster, you are optimizing the wrong variable. Use the speed to test more ideas, then spend the saved budget on the one that deserves craft. That is the same logic agencies used when they repriced creative work after AI: the production got cheap, so the thinking got expensive.
Treat disclosure as part of production. The DM9 outcome shows what undisclosed manipulation can cost an entry and an agency. The Handbook lists acceptable uses, such as AI-assisted ideation, exploring concepts with clear human creative direction, enhancing production and analysing data, and it rules out fabricated results, fake proof and passing AI work off as human-made. Keep an honest AI-use log from the first frame, so you can answer the disclosure question (tools, extent, data sources, verification) without reconstructing it later. The same discipline protects you on the client side, where AI disclosure norms for ads are developing in parallel.
Finish the work by hand. If you generate, treat the output as a first draft that a human director, editor and colorist still have to bring to a finish. Knowing where a model's output falls short saves you from shipping generic work that gets a campaign mocked instead of awarded.
Prize money is also chasing AI entries. Luma AI ran the Luma Dream Brief, offering $1 million to creative work made with Luma AI that wins a 2026 Cannes Lions Gold Lion; entrants made commercials for Luma itself, and Luma announced an 18-person jury with leaders from Nike, HBO Max, Wieden+Kennedy, Chili's and others.

FAQ
Did an AI-generated ad win the Film Grand Prix at Cannes Lions 2026? The Film Grand Prix went to two Claude films by Mother London: ads about AI, not AI-generated ads. The entrants' One Show entry credits a director, a director of photography and a casting director, and says the AI characters' dialogue was built from a competitor chatbot's actual answers.
Did any work built on AI win a Grand Prix in 2026? Yes. Google's "Project Genie", an application of the Genie 3 model, won the Digital Craft Grand Prix, and VML Warsaw's "Lucky Fan Index" for Wisła Kraków, described by Cannes as an AI-driven tool, won the Creative Commerce Grand Prix.
What are the Cannes Lions AI Craft subcategories? New for 2026, they sit inside the craft-led Lions and recognise work where human creativity and AI together create ideas "that neither could achieve alone", with the focus on craft, artistry and intent where AI serves the idea.
Do you have to disclose AI use in a Cannes Lions entry? Yes. The AI disclosure question has been mandatory since 2024. It asks which tools you used, how much of the final work involved AI, the data sources behind AI-generated elements and how results were verified.
What happens if an entry is found to be faked? Under the Integrity Standards, disqualification, withdrawal of awards, exclusion from juries or a ban from future festivals, with escalated cases reviewed by an independent Integrity Council. Adweek reported bans of up to three years for deliberately misleading work.
