Kylian Mbappé has reportedly ended his 19-year sponsorship deal with Nike, with his contract expiring on July 31st and not being renewed. French insider Thibaut Vezirian suggests Mbappé is poised to join Swiss sportswear company On, a brand previously unknown in the football boot sector, in a move that is expected to send shockwaves through the industry. On, founded 16 years ago, has seen a meteoric rise, primarily in running shoes with its 'CloudTec' technology, and is currently valued at approximately $10.77 billion (£7.95bn) as of August 2026. This partnership would mark On's first foray into the competitive football boot market.

The proposed deal between Mbappé and On is far from a traditional endorsement. It is anticipated to be a unique and highly lucrative agreement where Mbappé will receive equity in On, in the form of shares, and is expected to launch his own "sub-brand" of signature football boots. This structure positions Mbappé as a partner rather than merely an ambassador, granting him significant influence over product strategy and brand building for On's football offering. This mirrors the successful model seen with Roger Federer and On, where Federer took a stake and helped develop products.

This partnership is seen as a watershed moment for sports marketing, potentially changing the nature of elite-level boot deals. It would allow Mbappé to directly share in On's growth as they leverage his global celebrity to turbocharge the launch of their first-ever football boot. While Nike, Adidas, and Puma have historically dominated the market, On's entry with Mbappé aims to disrupt this established order by offering a deal that traditional sportswear giants might find difficult to match, particularly regarding equity and a dedicated sub-brand.
