On the morning of 18 September 2026, the Swiss brand On said it was entering football, and it said the entry was happening alongside Kylian Mbappé.
Here is what On, Bloomberg and Sportico all confirmed on the day. Mbappé becomes a global ambassador for On and will work directly with its product teams on football footwear and apparel, with the boots built around On’s LightSpray technology. The move ends a relationship with Nike that ran close to two decades; his Nike contract expired on 31 July 2026. Thierry Henry, On’s Director of Football since late 2025, is the man who brought him in. All of that is on the record.
Now the part that is reported, not confirmed. Sportico and Heavy, also on 18 September, described the deal as including an equity stake for Mbappé, structured “on the Federer model,” alongside a signature sub-brand and a term of roughly a decade. On’s own announcement uses none of those words. It says ambassador. It says product development. Neither side has disclosed a single financial term.
The Jordan cut
The template for what Mbappé is reportedly chasing is forty-two years old and belongs to a man who never kicked a ball.
In 1984, Nike signed Michael Jordan to a five-year deal worth around $2.5m, roughly $500,000 a year, which was already far above the going rate for a rookie. The number that mattered was not the fee. It was the structure: Jordan took a cut of every Air Jordan sold rather than a flat cheque. Deloris Jordan, his mother, is widely credited with pushing the family to demand a percentage, a piece of oral history documented well enough to end up dramatised in the 2023 film Air.
That structure compounded like nothing an endorsement fee can. Sportico estimated Jordan earned around $300m in 2024, most of it Nike and Jordan Brand royalties, on Jordan Brand revenue of roughly $6.6bn to $7bn. That is a conservative royalty of four or five per cent on a namesake business, decades after his last game, paid to a man in his sixties.
Every namesake athlete deal since descends from that structure. The lesson the smartest athletes drew from it is simple and expensive to ignore. A fee pays you for who you are today. A percentage pays you for what you help build.
The Warriors became an asset class
Somewhere between Jordan and Mbappé, the athlete stopped being the product and started acting like the fund.
The clearest example is a single locker room. Kevin Durant co-founded Thirty Five Ventures with Rich Kleiman. Stephen Curry runs SC30 Inc. Andre Iguodala moved into venture capital properly, co-managing a fund of around $200m, Mosaic General Partnership, with Rudy Cline-Thomas, on an early portfolio that has been cited as including Allbirds, Coinbase, Carta and Hims; he retired in 2023. For a stretch at Golden State, three men were winning championships on a Tuesday and reviewing term sheets on a Wednesday, in the same building, off the same proximity to Silicon Valley money.
The Warriors dressing room as a venture incubator is a characterisation, not a registered entity, and it should be read that way. What is not a characterisation is the behaviour. A generation of the highest-earning athletes decided that the most valuable things they owned were their name and their access, and that both were wasted on flat fees. They wanted equity, board proximity, upside. They started thinking like the people who used to sign them.
This is the class Mbappé already belongs to. He has a holding company, Interconnected Ventures, with an investment arm, Coalition Capital. He controls his own image rights, a fight he has picked more than once with people who employ him. The man does not rent well.
What On is actually selling
On’s pitch to that class is not a boot. It is the cap table.
The proof of concept is Roger Federer. He took an equity stake in On in 2019, reported at around three per cent for a reported investment near $50m, and he became a genuine shareholder rather than a paid face. When On listed on the New York Stock Exchange in September 2021, the stock popped around 46 per cent on its first day and valued the company at roughly $11bn. Federer’s stake was reported to be worth more than $300m around the IPO. More recent coverage in 2025 ties his billionaire status largely to that On holding, with its value reported somewhere between $375m and $500m. Read those figures as the reported estimates they are. Read the underlying fact as solid: he is an owner, not an endorser, and it made him a fortune no appearance fee could.
That is the gap On is working. Nike’s model is built on cash-and-royalty endorsements rather than company equity. Jordan Brand is the exception that proves it, a co-ownership structure on a namesake business, with Serena Williams’ arrangement cited as one of the few others in that bracket. This is a reading of how the model works, not a report of some boardroom decision to shut the door; nobody has announced a policy. But if you are a footballer who already behaves like an investor, an incumbent whose default is a fee and a room whose default is a slice are simply selling you different products.
On’s release, again, describes an ambassadorship and a product partnership, and discloses no terms. What Sportico and Heavy add is that the room, this time, reportedly includes a slice. If they are right, Mbappé has done in football what Federer did in tennis, and On has run the same play twice.
The honest counter-note
There is a problem with the tidy version of this story, and it belongs in its own section.
The ownership instinct is real, it has already been tested on grass, and it has not gone well. In the summer of 2024, with the takeover announced on 31 July, Mbappé’s Coalition Capital acquired around 80 per cent of the French club Stade Malherbe Caen for a reported €20m, bought from Oaktree Capital. At 25, he became the youngest majority owner in French football. It was the purest possible expression of the thesis: do not endorse the thing, own the thing.
Then the thing lost. Caen were relegated from Ligue 2 in 2024-25, their first full season under his ownership, after 41 years in the top two divisions of French football. They did not bounce straight back, finishing eighth in the third tier in 2025-26. As of this September they sit in the newly renamed Ligue 3, managed by Gaël Clichy, two divisions below where a normal week of Mbappé news operates.
So the record is split, and honesty requires holding both halves. Buying the club shows the instinct is genuine, that this is a man who reaches for control when a cheque was on offer. The results at Caen show the thing admiring profiles forget: ownership is a claim on the upside and the downside at once. It is not a magic wand. You can be the smartest name in the market and still get relegated, and both facts can sit inside the same career.
That is the case for taking him seriously rather than merely cheering. He keeps betting on control when renting would be safer and, on the Caen evidence, occasionally more comfortable. Most people with his leverage take the cheque. He keeps asking for the keys.
The percentage, forty-two years later
On 18 September 2026, Mbappé confirmed he would help design a boot. Sportico and Heavy reported he was handed a piece of the company that makes it. If the second thing holds, the boot was never the point, the same way the $500,000 was never the point in 1984. Somebody signed Jordan’s fee. Deloris Jordan asked for the percentage. Forty-two years later, the best player in the world walked into a Swiss shoe brand and, if the reporting is right, asked for the same thing. The face is still for rent everywhere. He has reportedly decided he would rather own the building.
