Kylian Mbappé signed an equity partnership with On, the Swiss running brand, ending a relationship with Nike that began when he was thirteen. The deal makes him the first Real Madrid athlete in the club's modern era to wear competition footwear not supplied by the Oregon brand. Nike has held Madrid's kit contract since 1998 and historically bundled individual players into global ambassador portfolios. Mbappé's previous Nike deal, negotiated in 2019, was estimated at $18 million annually through 2029.
The On arrangement is structured as a co-ownership model. Mbappé receives equity in the company—ticker ONON, market cap $14.7 billion as of Friday—plus royalties on a signature football boot line launching in late 2025. He will not receive a traditional endorsement fee. On declined to specify the equity percentage but confirmed the stake vests over five years and includes board observation rights. The company's last comparable athlete deal was with Zendaya in 2023, who received 0.25% of outstanding shares. Mbappé's contribution to product development includes motion-capture data from his sprint mechanics, which On's Zurich lab is reverse-engineering for a laceless cleat prototype.
The departure is the first high-profile defection from Nike's football stable since Neymar briefly considered Puma in 2020 before re-signing. It arrives as Nike's global football revenue declined 6% year-over-year in fiscal 2024, the first contraction since 2017. The company's athlete marketing budget has shifted toward basketball and running, where margins are higher and product cycles faster. Meanwhile, On's athletic footwear revenue grew 52% in the same period, driven by the Cloudmonster running shoe and tennis partnerships with Iga Świątek and Ben Shelton. The brand's strategy borrows from the Curry playbook: Under Armour's 2013 deal with Stephen Curry included equity and product control, turning a $4 million annual fee into a stake worth north of $200 million by 2018.
For Real Madrid, the shift creates inventory complexity. The club's Nike kit deal runs through 2028 at €120 million per season, but individual equipment clauses allow players to wear non-Nike boots if those brands pay a €2 million annual override fee to the club. Mbappé's On contract includes that payment, routed through a subsidiary registered in Geneva. Madrid has thirteen players under personal Nike contracts; Mbappé is now the fourteenth supplier in the locker room. Equipment managers will stock On studs alongside Adidas, Puma, New Balance, and two players who wear custom Mizuno.
The deal's structure reflects a broader recalibration. Athletes with social followings above 50 million—Mbappé sits at 127 million on Instagram—are increasingly treating endorsements as venture opportunities rather than licensing agreements. Naomi Osaka's 2021 move to her own apparel line, backed by Nike as an investor rather than sponsor, yielded a company valuation of $300 million within eighteen months. Mbappé's team, led by his mother Fayza Lamari and attorney Delphine Verheyden, spent six months modeling equity scenarios before approaching On in early 2024. They passed on a $25 million annual renewal offer from Nike that included no ownership component.
On's risk is execution. The company has never produced a football boot. Its Cloudsurfer running shoe uses a foam midsole unsuited to lateral cutting forces, and its supply chain runs through Vietnam factories with no experience in synthetic leather molding. The firm hired two designers from Adidas's Speed division in March and is piloting a cleat at its Portland innovation lab, but the product will not reach retail until Q4 2025. If the boot underperforms or injures Mbappé, the equity becomes a liability. The company's stock fell 3.8% on the announcement, suggesting institutional skepticism.
Watch for Nike's response in the January 2025 transfer window. The brand historically retaliates through competitor signings—when Cristiano Ronaldo left for his CR7 line in 2016, Nike signed Mbappé six months later. Jude Bellingham's contract expires in July 2025, and his agent has fielded calls from both Nike and On since November. Madrid's next kit cycle begins 2028, and On is expected to submit a bid, though its largest team deal to date is €8 million annually with Swiss club FC Basel.
Mbappé debuts the On cleat prototype in a February testimonial match against Paris Saint-Germain, the club he left for Madrid last summer. The game is at Parc des Princes. He will wear white boots.
The takeaway
First Nike defection from Real Madrid in decades reveals athlete equity deals now compete on ownership, not fees.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
