Taylor Swift — The $1.3B Girlfriend Effect

Swift was already a billionaire before dating Travis Kelce, but their relationship created the most economically significant romance in sports history. NFL viewership among women 18-49 jumped 7%. Chiefs merchandise sales spiked 400%. Kelce's endorsement portfolio grew from $5 million to $20+ million. Her Eras Tour grossed $2.2 billion. She's worth $1.3 billion. Travis is worth $40 million. The "girlfriend" is 32x richer than the athlete. When Taylor showed up at Arrowhead Stadium, she didn't become a WAG — she turned the entire NFL into a Taylor Swift concert with a football game attached.
