Kylian Mbappé, the celebrated French footballer, has reportedly concluded his 19-year endorsement deal with Nike. This significant move sees him align with On, a Swiss sportswear firm, in a partnership that deviates from traditional athlete sponsorships. The new agreement is rumored to include not only a substantial financial package but also an equity stake in On for Mbappé, alongside the creation of his own signature football boot sub-brand.

This decision marks a major strategic shift in sports marketing, particularly for Nike, which has nurtured Mbappé since he was eight years old. Losing him, especially as he enters his prime and plays for Real Madrid, is considered a considerable blow to their football marketing efforts, particularly in their ongoing competition with rivals like Adidas. Industry insiders suggest this move reflects a growing trend where top athletes seek deeper, more integrated business relationships beyond mere endorsement fees.

On, founded 16 years ago, has rapidly ascended in the running shoe market, achieving a valuation of approximately $10.77 billion (£7.95 billion) as of August 2026. This partnership with Mbappé signifies their inaugural foray into the highly competitive football boot sector. Mbappé's involvement, particularly his potential influence on product strategy and brand building, is expected to provide On with instant global credibility and a powerful marketing platform, similar to the impact of Michael Jordan's brand for Nike in basketball.
