Joao Fonseca has achieved a major social media milestone by becoming the youngest tennis player to amass 1 million followers on Instagram at just 18 years and 7 months old. This accomplishment, reached during the Miami 2025 tournament, places Fonseca ahead of some of the sport’s biggest names in terms of social media impact.
By comparison, Emma Raducanu reached this milestone at 18 years and 10 months during her sensational US Open win in 2021. Carlos Alcaraz followed at age 19 after his victory in Madrid in 2022, and Coco Gauff achieved 1 million followers at 19 years and 6 months after her memorable US Open performance in 2023.
Fonseca’s popularity has been fueled by his dynamic presence on and off the court, with fans drawn to his engaging content and remarkable talent. This milestone not only highlights his growing influence in the sport but also his ability to connect with a global audience at such a young age.
