While adidas, Nike and PUMA outfit 37 of 48 nations at the 2026 World Cup, sportswear challengers Castore and Macron have built toward €500 million by refusing to compete for national federation deals, raising the question of whether the grassroots playbook that got them here can take them to €1 billion.
This month, 48 nations take the field across the United States, Canada and Mexico for the largest FIFA World Cup in history. Thirteen kit brands are competing for visibility across at least 96 home and away shirts, billions of broadcast impressions, and the most commercially intense sporting window of the decade. Adidas outfits 14 teams. Nike, 12. Puma, 11. The Big Three together account for 77 percent of all participating nations.
And Castore and Macron? They are nowhere to be seen.
That absence is not an oversight. It is a strategy.
Neither challenger has pursued a national federation deal at World Cup level. While the giants pour hundreds of millions into kit rights for Germany, Brazil, Argentina and France, and while smaller brands like Kelme, Kappa, Reebok and a Colombian start-up called Saeta scramble for a single-nation foothold, Castore and Macron have stayed out of that room. The World Cup is not their battlefield. The grassroots is.
That choice is the clearest expression of a challenger brand philosophy that this column has been tracking. To understand why it matters, it helps to understand what the World Cup kit game actually costs, what it does not deliver, and what it requires to generate a real ROI.
Choosing the right battlefield
Conventional wisdom in sportswear holds that scale requires a shoe. Nike built an empire on the Air. Adidas, on the Samba. Footwear remains the commercial engine for both giants, accounting for 66 percent of Nike’s brand revenue and 57 percent of Adidas’s. Apparel is the follow-on category, the margin improver, the afterthought that arrives once the shoe has earned its shelf space.
Again, Castore and Macron never got that memo.
Both challenger brands play differently. Full focus on the apparel category. Some equipment to fill out the assortment, but apparel is the growth driver and brand anchor.
Meanwhile, from Breaking 2 - when Kipchoge ran 1:59:40 on a specially prepared course in Vienna in 2019, never officially ratified - to Sabastian Sawe’s 1:59:30 in London this April, the first legally recognized sub-two-hour marathon, both giants have poured hundreds of millions into elite running. The return is real. But the cost is extraordinary, and the runner who buys a race shoe is not buying a club kit.
Again, the challengers have stepped away from that battle and identified the same gap: fan-based and community-driven sports hungry for a credible kit partner. Fitness. Rugby. Cricket. Football. Tennis. Motorsport. Categories where the attachment to the shirt is tribal, where the club or team, not just the athlete, is the brand.
Neither Castore nor Macron competes in running. Both are pure apparel specialists: no footwear, very limited equipment. That is the shared foundation. From there, their growth playbooks diverge.
The club playbook: Macron
Macron reached €244.6 million in revenue in 2025, growing 9.4 percent year over year. Its EBITDA margin of 21.1 percent is the number that stops most industry observers – a level the giants, with their vast footwear supply chains and billion-dollar marketing budgets, do not approach.
Two structural differences explain it. The first is inventory: a large, centralized warehouse holds thousands of SKUs, each with a three-to-five-year product lifecycle. No six-month seasonal resets, no markdown cycles, no obsolescence pressure. Overall, a giant infrastructure adjacent to Macron’s Bologna headquarters: a 16,105 m² warehouse holding 7 million items, with capacity to ship 80,000 units per day.
The second is distribution: Macron’s regional hubs carry no inventory themselves. They function as lean intermediaries between the central warehouse and the clubs they serve, taking limited margin, with fulfillment executed directly from Bologna. No expensive retail layer. No stock risk at the point of distribution.
The economics compound into a margin that most apparel businesses can only admire.
How to explain those differences? Macron focuses on clubs and club kits, offering local services through hubs and collections that do not change every six months.
The visibility model is equally disciplined. Macron does not sponsor athletes. It partners with clubs, sports associations and federations, including UEFA referees across European competition, building brand recognition through the sports ecosystem rather than individual personalities. The result is a brand that fans and athletes recognize, not just procurement officers. That distinction separates it clearly from commodity kit manufacturers who serve the same market without building a consumer brand.
The retail playbook: Castore
Castore’s path was rawer. The Beahon brothers began by gifting free kit to personal trainers at upmarket London gyms, paying commission on every online sale their clients made. Consumer activation was built directly into the distribution model, with no marketing budget required.
That scrappiness evolved into a deliberate sponsorship strategy. First came Andy Murray in 2019, whose endorsement gave the brand credibility and reach. Then, in 2020, came Glasgow Rangers – Castore’s pivotal first football deal, worth a reported £25 million over five years, and a calculated bet on a club with global reach and a fanbase starved of commercial attention after years of legal disputes with Sports Direct. Newcastle United, Aston Villa, Bayer Leverkusen, McLaren F1 and others followed.
Growth at that pace, however, carries its own risks. Castore lost six major football kit partnerships in two years – Newcastle, Aston Villa, Wolves, Bayer Leverkusen, Sevilla and Rangers – amid persistent complaints about ripping shirts, wet-look fabrics, peeling logos and supply chain failures. Quality had not kept pace with ambition. It is a tension the brand has not yet fully resolved.
Still, it has not slowed the retail push. Castore now operates a rapidly expanding mono-brand retail network ****across the UK and Ireland, with flagships in London and Dubai Mall, and co-founder Tom Beahon has signaled ambitions for 30 to 50 further openings. Backed by £150 million in new investment and a near-£1 billion valuation, the brand is moving fast.
Notably, Cricket West Indies moved from Castore to Macron in a recent multi-year deal: a small data point, but a revealing one. The two challengers are competing for the same type of client: federations and associations that want a credible, specialist kit partner rather than a commercial afterthought on a giant’s portfolio.
The €500 million question - and the €1 billion one
The two brands are approaching a meaningful threshold. €500 million is achievable through disciplined scaling of the current model: more sports, more clubs, more geographies, more hub coverage. The unit economics should hold. Macron’s 22nd consecutive year of growth and Castore’s recent £150 million investment round suggest the momentum is there.
Beyond it, the questions multiply.
For Castore, the retail ambition raises familiar pressures: how much consumer pull can sustain 80-plus stores? What product fills the shelves beyond kit partnerships, which are term-limited by contract and carry execution risk, as recent club losses have shown? What does the IT and logistics infrastructure cost at that scale?
JOTT, the French casualwear brand that entered receivership in December 2025 after investor-fueled expansion drove operational collapse, revenue falling 28 percent in a year, and €117 million consumed, is the cautionary tale. Growth that outpaces operational capacity is not a funding problem. It is a structural one.
For Macron, the stretch is different. Its B2B hub model has a natural ceiling in team sport. The path beyond leads into direct consumer territory. The O.N.E. lifestyle collection (“Own Nothing Else”), a contemporary Activefashion line that marks a significant departure from pure team kit, is the vehicle. The Gran Reno store near Bologna is the first careful experiment: focused on athleisure, padel and running rather than club kits. Tentative by design.
The €1 billion ceiling will likely require decisions the current model has carefully avoided. Can the Macron hub system scale infinitely, or does it eventually need an equivalent B2C retail network? Can the brand resist wholesale relationships, and the intermediaries and seasonality that come with them, that the model was originally designed to bypass? And does footwear become commercially unavoidable at that scale for either brand?
The playbook that got Castore and Macron to €500 million – built on careful marketing investment, sports niche, category discipline and distribution reinvention – may not be the same one that takes them to €1 billion.
2030 - 2034. The question no one is asking yet.
When the 2030 World Cup kicks off across Spain, Portugal and Morocco – with symbolic opening matches in Uruguay, Argentina and Paraguay to mark the tournament’s centenary – how many national teams should we expect to see wearing Castore or Macron? And when the world gathers in Saudi Arabia in 2034, will either brand finally have a shirt on the biggest stage in football?
The honest answer today is: we do not know. Neither brand has publicly announced a national federation strategy for international tournaments at that level. But the conditions are shifting.
The 2026 World Cup will feature 13 different kit brands across 48 nations – up from just six challengers represented in 2022. Each tournament, the market fragments a little further. Smaller federations, newly qualified nations and associations from emerging football markets are looking for partners who understand their scale and their community, not brands chasing broadcast minutes on a Germany or Brazil shirt.
That is precisely the terrain where Macron and Castore have been building. Macron already outfits national-level cricket sides at the T20 World Cup, supplies federations across rugby, basketball and handball, and partners with Welsh Rugby Union on a seven-year deal. Castore has learned, expensively, that club-level football demands flawless execution at scale. Both lessons are preparation.
The grassroots strategy is not a consolation prize for being shut out of the World Cup. It is a land grab for the clubs, federations and associations that feed into the national teams of the future. Win the shirt at community level, and you are already in the conversation when a newly qualified federation goes looking for a kit partner that knows their sport, their scale and their audience.
The three variables – sport, product category and distribution – each carry a different growth ceiling. National football is not yet one of those variables for Castore or Macron. The question worth asking now is when it becomes one.
That is not a criticism. It is the most interesting question in challenger brand strategy right now.
