Columbia Sportswear and adam&eve\TBWA won the Brand Experience & Activation Grand Prix at Cannes Lions 2026 for ‘Expedition Impossible’, a campaign that offered the entire company to anyone who could prove the earth was flat. Nobody claimed the prize, but 80 million people were watching.
Columbia Sportswear won the Brand Experience & Activation Grand Prix at the 2026 Cannes Lions International Festival of Creativity for “Expedition Impossible,” a campaign that offered the company’s entire asset base to anyone who could prove the earth is flat. The work was created by adam&eve\TBWA in London.
The challenge nobody could win
The campaign launched with an open letter from Columbia chief executive Tim Boyle, published as a print ad in The New York Times. In the letter, Boyle invited flat earth theorists to find the edge of the planet and document it with a photograph. The prize: full ownership of the company, including warehouse facilities and office equipment. Nobody claimed it.

The campaign then spread across Columbia’s social channels, YouTube and Reddit, generating an earned audience of 80 million people. According to Cannes Lions organizers, the campaign entry cited strong negative reaction from flat earth communities, the so called “flatters.”
The work sits within Columbia’s broader “Engineered for Whatever” platform, which uses extreme challenges and adventures to demonstrate the durability of its outdoor products.
Two years in the making
According to campaign interviews, the work traces back to a letter Columbia’s president sent to leading creative agencies about two years ago. Matt Sutton, the brand’s senior vice president and head of marketing, said the yearlong collaboration with adam&eve\TBWA was built on “trust and courage.”
Why this matters beyond the trophy
Jury president Rafael Pitanguy praised the campaign for being both formally precise and culturally pointed. He highlighted the quality of the copywriting and Boyle’s performance on camera, saying the work “isn’t afraid to step into controversy and challenge irrationality.”
Pitanguy also pointed to a wider trend: brands leaning into perceived weaknesses rather than concealing them, building narratives around the tensions their audiences might question. “Expedition Impossible” is a clean expression of that logic, using the premise of an impossible expedition as the campaign’s fulcrum.
The 80 million earned reach figure, achieved without major media spend on the stunt itself, points to a model that may be increasingly viable, especially for brands outside the Nike and adidas tier that cannot match paid media budgets.
The Brand Experience & Activation category received 1,561 entries this year, according to Cannes Lions organizers. Gold Lions went to work from Peru, Poland, Brazil, Canada and Mexico, as well as collaborative teams from the US, New Zealand, Italy and elsewhere.
