Concrete evidence of the ‘Taylor Swift effect’ is challenging to quantify, but the NFL Players Association presented compelling data in its yearly report to the US Department of Labor. 

According to the union filing, there was a remarkable 177% surge in group licensing and marketing income for Travis Kelce, tight end for the Kansas City Chiefs and Swift’s boyfriend, following the commencement of their relationship at the start of the 2023 NFL season. 

In total, the three-time Super Bowl champion amassed $2.4 million, positioning him as the fourth-highest earner among NFL players in terms of licensing income. This revenue stream encompasses various products such as video games, trading cards, and replica jerseys.
