The beach reshuffle
The most-watched change: PMG has taken over the beachfront space WPP used to occupy. PMG's AI & Tech Sandbox runs June 22-26 at Miramar Beach, with programming from Forrester, Shamrock Capital, Providence Equity, and a hackathon designed to push past surface-level AI talk. The pitch is discovery, not panels.
WPP has moved up the hill. The group's 2026 presence sits at The WPP Rooftop at the Martinez Hotel — hospitality, interactive demos across media, creativity, production, and enterprise solutions, and curated studio moments. The move tracks with CEO Cindy Rose's Elevate28 strategy: fewer flagship physical assets, more concentrated agentic-platform demos.
Stagwell's Sport Beach, the Official LIONS Sport Partner for 2026, returns to Plage du Festival from June 21-25. The host roster reads like a multi-network reunion — 72andSunny, Allison Worldwide, Anomaly, Assembly, BERA.ai, Code and Theory, DonerColle, GALE, Hunter, The Marketing Cloud, and TEAM. Adobe, PepsiCo, Diageo, Gatorade, and NBCUniversal anchor the partner stack. Athletes include Cooper Flagg, Lando Norris, Shaq, Naomi Osaka, Carlos Sainz, and Lindsey Vonn. Sport Beach has now spun out as its own company.
Meta Beach, Pinterest Manifestival, TikTok Garden at the Carlton, Motel Yahoo!, and Chez Vayner are all back. The FQ Equality Lounge at Hôtel Martinez and Influential Beach at La Mandala add programming for diversity and creator-economy conversations. The unofficial side-events guide tracks more than 250 activations across 85 organizers.
Who's on the PR Lions jury
The PR Lions Shortlisting Jury for 2026 is led by holdco talent. Among the eighteen members: Felipe Braz Costa (Executive Creative Director, Edelman, EMEA), Eleanor Sullivan (Chief Strategy Officer, Burson, UK), Deirdre Murphy (Global Client Partner, Ketchum, Global), Louisa Hager (Group Creative Director, Weber Shandwick, USA), Andres Ortiz (Partner and General Director, LLYC, Colombia), Björn Mellstrand (Head of Strategy, JMW Kommunikation / JMWGolin, Sweden), and Marc Antoine Koreki (Managing Director, Havas Africa Côte d'Ivoire) — plus a strong slate of indie chiefs including GLG Communications, K.A.Muses Group, The Conversation Strategists, and One Plus One Communications.
Composition matters. The jury picks what counts as great PR work for the year — and the indies have meaningful seats at the table.
The integrity overhaul
After a 2025 festival marked by AI-manipulated case studies, unverifiable claims, and revoked trophies, Cannes Lions has tightened the entry process. The 2026 rules include human and AI fact-checking, stricter client sign-off, and bans of up to three years for agencies caught submitting fake work. The festival published an Integrity Handbook last November and ran webinars through the spring.
Translation: the AI-enabled case-study theater is over. Provenance matters now. So does the math behind the claim.
The new awards
Two structural changes worth flagging. The Creative Brand Lion debuts — recognizing the internal systems and cultures that make repeatable, world-class creative possible inside a brand. AI Craft subcategories are now embedded across craft-led Lions, recognizing work where human creativity and generative AI collaborate. The Creative Data Lions now require entries to show how data was central to the idea and led to measurable business results.
The Lions have officially moved from "AI was used" to "AI was integral, and here's the proof."
The AI theme — but smarter
The headline AI talent on stage includes a Demis Hassabis fireside on the future of creativity, and Oprah Winfrey on storytelling and influence. The PMG AI & Tech Sandbox is the most concentrated AI venue. WPP, Omnicom, Publicis, Stagwell, and the independents all have AI tooling demos lined up across the week.
The mood, though, is different than 2024 and 2025. As one industry preview put it heading in: the AI hype era is over, and proof is the new flex. After two years of synthetic influencers and automated content flooding timelines, the question marketers are now asking is whether any of it actually worked. The 2026 work that wins is expected to feel less machine-generated, more human-engineered.
What it means for buyers
If you're a CMO buying agency services, Cannes 2026 is your annual capability scan. Three things to watch:
- The agency's AI demo. Is it a tool that ships real client results, or a sizzle reel of features? Cannes 2026 separates the two.
- The integrity story. Agencies that can show provenance, fact-checking, and outcome math are the ones building credibility in the new measurement era.
- The PR Lions winners. The PR jury this year is rich on indies and EMEA talent. Watch which campaigns clear the bar.
The Croisette is still about parties, yachts, and rosé. But the work that matters is being judged against a tighter standard than it was last year — and the agencies showing up with proof, not promises, are the ones who own the headlines on the flight home.
