In Herzogenaurach, two brothers once stopped sharing a factory. Adi Dassler founded Adidas on one side of the river, Rudolf Dassler founded Puma on the other. Same town, same craft, same starting point — but eighty years later, in the same World Cup cycle, the two brands are telling completely opposite stories.
Puma has officially called 2026 a "transition year." Third-quarter organic sales dropped 10.4%, operating profit collapsed by more than 80%, and the company itself pointed to weak brand momentum and excess inventory as the cause. This wasn't a quiet decline: in the same period, Puma had tripled its World Cup marketing investment compared to 2024, pulled Portugal's kit sponsorship away from Nike, and launched an aggressive Gen Z push with its "Go Wild" campaign. Signal was louder than ever. The outcome went the other way.
Adidas, meanwhile, gained real momentum in the same market during the same window — enough that Puma itself became the subject of takeover speculation.
What's interesting here isn't the budget gap. Puma didn't spend less, it spent more. The problem was that the louder signal never converted into value, and the value never converted into outcome. Excess inventory means the product wasn't reading demand correctly. The Gen Z push landed on top of brand momentum the company itself admitted was already weak — the message went out before there was solid ground underneath it. Winning a sponsorship is a signal win. Whether that sponsorship turns into sales, margin, or market share is an entirely separate question.
This split is now becoming formal industry language, too: IAB's Measuring Visibility in the AI Era framework, released this month, draws an official line between "directional" measurement — visibility, mentions, signal — and "decision-grade" measurement — verified data that actually converts into outcomes. Puma's case is the most concrete version of that line showing up not in advertising theory, but on an actual balance sheet: a loud signal, on its own, guarantees nothing.
At Sellf, we look at this through three layers: Signal, Value, Outcome. Puma genuinely won the top layer — visibility, sponsorship, campaign volume. But the two layers underneath — the product meeting real demand with the right inventory, and that meeting turning into profit — weren't ready. Adidas's momentum in the same window likely didn't come from winning a budget war, but from having all three layers aligned at once.
Same DNA, same market, same cultural moment — and a completely different result. Which is exactly the point we keep making: growth isn't measured by how much you spend. It's measured by where what you spend lands inside your system.
