Starting in 2026, Cannes Lions will implement stricter entry protocols requiring dual sign-off from both the agency lead and the brand marketer. This significant shift marks the beginning of a new integrity framework designed to restore trust and raise standards across the creative industry.
The move follows the high-profile withdrawal of DM9’s Creative Data Grand Prix earlier this year, after revelations of manipulated results undermined the award’s legitimacy. The scandal served as a wake-up call for the global festival, prompting immediate action to prevent similar breaches of ethics in the future.
To combat misinformation and synthetic manipulation, Cannes Lions will introduce a hybrid “Dual Verification” system combining human oversight with AI-powered checks. The process will involve manual review of claims alongside automated fact-checking and pattern detection to flag inconsistencies or potential misuse of data and content.
Crucially, an official “AI Integrity Handbook” will accompany this rollout, defining acceptable practices for using generative tools and synthetic media in campaigns. By setting a clear standard, Cannes aims to separate legitimate creative innovation from artificial deception.
The festival is also raising the stakes when it comes to misconduct. From 2026 onwards, any entry found to be in violation of rules can be disqualified—at any stage, including after awards have been granted. More severe penalties include suspension or bans of up to three years for offending agencies, brands, and even jury members involved in the process.
To enforce these new standards, an independent Integrity Council will be established alongside an annual audit of shortlisted and awarded work. This added layer of scrutiny reflects Cannes Lions’ commitment to making credibility as crucial as creativity in the judging process.
As CEO Simon Cook stated: “Creativity only matters if it’s credible—and credibility must be earned.” With these reforms, Cannes Lions is sending a clear message: in a rapidly evolving media landscape, honesty, accountability, and transparency are no longer optional—they are non-negotiable.
