For years, crisis communications has run on one instinct: caution. Contain the story, minimise the damage, say as little as possible. This year’s PR Lions Grand Prix winner argued the opposite — and the industry agreed.

KitKat’s “KitKat Heist,” created with VML UK and Burson, took the top prize in the PR category by turning a genuine commercial loss — 12 tons of stolen chocolate — into a public event. Audiences were invited to help find the missing KitKat via a live “KitKat Tracker,” turning what could have been a quiet supply-chain problem into a real-time, participatory story. The results: a 31% share of voice across 93 markets and $224 million in earned media in just 10 days.

What makes the win significant isn’t the stunt itself — it’s what the jury chose to reward. PR Lions jury president Dana Tahir, CEO of Havas Red Middle East and Egypt, was explicit that the work didn’t eliminate risk, it choreographed it: every line was calibrated to keep the brand on the right side of the story while still being fast, funny and human. As Nestlé’s Liberato Milo put it, the level of public participation “could not be manufactured” — it was the payoff of decades of brand affection meeting a platform people felt was theirs as much as KitKat’s.

That instinct turned out to be the thread running through so many conversations in Cannes this year.

1. The story doesn’t belong to the brand anymore, and that’s a PR problem now, too

The clearest shift at Cannes 2026 was from message delivery to story transfer: brands no longer just speak while audiences listen and media relays the message. Increasingly, brands create something — a behavior, an experience, a moment — that other people choose to carry, adapt and repeat. Unilever’s session on this made the point sharply: the operative question isn’t “what do we want to say?” but “what do others want to carry?”

For PR and comms teams, this is no longer a media relations issue alone — it’s an earned and owned media issue at once. Trust is increasingly built through the lived stories of creators, customers and frontline staff, not corporate messaging. That means the comms function’s job is shifting from crafting the story to designing something worth other people telling.

2. AI can produce the plumbing, but comms still needs to supply the poetry

AI dominated the show floor, but the more useful conversations weren’t about automation replacing judgment — they were about how scarce judgment becomes when production is cheap and infinite. Demis Hassabis reminded audiences that today’s AI still lacks sustained reasoning and genuinely novel thinking. Sir John Hegarty put it more bluntly: the industry has gotten too good at precision and targeting, and not good enough at persuasion.

Unilever’s “poetry and plumbing” framing is the useful shorthand here. The plumbing — automation, data, systems — is what lets comms teams monitor and respond at scale (as KitKat’s

real-time tracker proved). But the poetry — cultural insight, timing, tone, judgment about what’s actually worth saying — is still entirely human, and it’s what separates a genuinely resonant response from a fast one.

3. Creators are becoming a media relations channel in their own right

The creator conversation at Cannes has moved well past “influencer marketing.” Creators are increasingly treated as operators — building communities, formats and even media businesses of their own, as Alex Cooper’s appearance on the Mixed Signals podcast underscored. That shift matters for comms teams specifically: creators now function less like paid amplifiers and more like independent media outlets with their own trust equity and audience relationships.

The risk Cannes surfaced is treating creators as inventory to be bought and measured like ad placements. Their actual value — the thing that makes them useful in a crisis or a launch — is trust, voice and cultural fluency. That’s a relationship to be managed the way you’d manage any high-value media relationship, not a line item to be optimised.

4. Integration is no longer a structure, it’s a response-speed advantage

Beneath the AI and creator debates sat a quieter theme: marketing and comms functions are being judged on whether their capabilities can move at the speed of a live story — not whether they individually exist. The contrast between the Palais (ideas) and the beachfront (platforms, data, automation) captured this well: the advantage now lives in the connection between the two.

This is exactly what made “KitKat Heist” possible. VML UK CEO Ryan McManus described the campaign as reacting to “a brief that came from the real world” — the win depended on creative, social and PR functions operating as one team with shared decision rights, not a chain of approvals. For comms leaders, Cannes reframed integration as a genuine competitive capability: the ability to protect brand meaning while responding in real time, without a formulaic, over-managed response killing the moment.

5. Trust is proven in behavior, not claimed in statements

The trust conversation at Cannes this year was less about purpose campaigns and more about operational credibility — what brands actually do under scrutiny. Patagonia’s Alex Weller described the brand’s “Forward, not Flawless” approach to sustainability reporting, arguing that admitting unfinished progress, including on difficult metrics like Scope 3 emissions, is more credible than over-claimed certainty. Hinge’s “designed to be deleted” positioning made a similar point: the brand becomes more believable by acting consistently with its stated mission, not by saying it louder.

For PR professionals, this is the throughline back to KitKat: the campaign worked not because of clever copy, but because it was consistent with a brand people already trusted enough to want to participate. Increasingly, the brand is judged less by what it says in a press release and more by what people experience — and are willing to publicly vouch for — in real time.

Cannes Lions 2026 rewarded organizations willing to treat a crisis, a customer story, or a cultural moment as raw creative material. Whether it was a stolen shipment of chocolate, a creator’s community, or a brand’s willingness to admit it isn’t finished yet, the throughline was the same: the story doesn’t belong to the brand alone anymore, and the organizations winning are the ones building for that reality — not fighting it.
