Federer's Billionaire Status in Jeopardy as On Holding Shares Plummet

Roger Federer's net worth took a significant hit on Tuesday, August 11, 2026, after shares in On Holding, the Swiss sportswear firm he co-owns, plummeted nearly 19%. The single-day slide erased at least £38.5 million ($52 million) from his fortune within hours.

The estimated net worth of the tennis legend dropped to £705 million ($952.4 million), down from an estimated £814 million ($1.1 billion) earlier this year, according to Forbes. This leaves Federer just shy of the billionaire threshold he crossed for the first time only a year ago.

On Holding's second-quarter results were released on Tuesday, which showed net sales of 850.4 million Swiss francs (£595 million/$1.04 billion), a 13% year-on-year rise. However, this figure fell short of analysts' expectations of 878.4 million francs (£614 million/$1.08 billion).

Federer holds an approximate 2.5% stake in On Holding, or roughly 637 million shares. This stake first pushed his fortune past the £740 million ($1 billion) mark in August 2025, making him one of only seven athletes to reach billionaire status.
