Nike is facing a major challenge as Kylian Mbappé, one of its most prominent athlete endorsements, has left the brand after nearly 20 years to join On, a fast-growing competitor. On has offered Mbappé equity, signaling a significant shift in athlete-brand relationships, where athletes now seek ownership stakes and deeper involvement rather than traditional endorsement deals. This move is particularly noteworthy because Mbappé’s switch embodies a rising trend of challenger brands targeting Nike’s core athletes and cultural influence directly, rather than merely competing for consumers around the edges.

Meanwhile, Nike’s position in the Dow Jones Industrial Average is under threat due to an 80% decline in its share price from its peak, having already been dropped from the S&P 100 earlier this year. Although removal from the Dow would be a public symbol of Nike’s recent struggles, the market’s true concern centers on the company's competitive position and ability to execute its turnaround strategy amid rising threats. The real story isn't index status, but whether Nike can innovate fast enough to maintain its market share and prestige in a landscape with aggressive emerging rivals like On, Adidas, Hoka, and Puma.

On is aggressively expanding into football (soccer), a key category for Nike, by not only signing Mbappé but also hiring Thierry Henry as director of football. The company’s strategy involves leveraging these respected athletes to gain credibility and market traction as it prepares to launch its first football boots in 2027. For Nike, the loss of Mbappé is more than just losing one athlete; it signals a new paradigm where athletes wield greater influence and expect more than traditional sponsorships. This puts Nike at risk of eroding its cultural relevance among younger consumers over time if rival brands continue to attract elite talent.

Nike has taken steps toward recovery, like repairing relationships with wholesale partners and focusing on product innovation, exemplified by the strong early sales of the Vomero 18 running shoe. Still, the company's turnaround is far from complete, with ongoing challenges in China and pressure from smaller brands. Activist investors may find Nike attractive due to its valuation and past capital allocation missteps, but Nike’s governance structure limits outside influence. Ultimately, Nike’s future depends on demonstrating sustainable growth through execution—improving full-price sales, gaining market share in football, and maintaining its cultural connection to athletes and consumers.
