Roger Federer's billionaire status has taken a hit after a sharp fall in On Holdings shares, wiping around $52 million of his wealth. AdThe Swiss athletic shoe and performance sportswear company's shares fell around 22% on Tuesday after the company reported weaker-than-expected second-quarter sales, missing Wall Street’s expectations. The shares fell to around $31.48, their lowest level in nearly two years. In August 2025, Forbes stated that Federer was worth $1.1 billion, reaching billionaire status.
