His father, Claudio Ricardo Wild, manages several tennis academies in Brazil, and his mother, Gisela Christine Seyboth, is a doctor.

It's the place I'm supposed to be. The court gives me limits, but at the same time it gives me the space and inspiration to do what I like. Tennis allows me to be myself and express myself on court." Seyboth Wild commented on the sport.

## Career
### 2018: Junior Grand Slam title, ATP debut

### 2019: First ATP Challenger title

### 2020: First ATP Main Tour title, Top 125 and Major debuts

In the next round, he faced world number 32 Borna Ćorić, losing in the third set tiebreak. With this result, he entered the world top 200 for the first time on February 24, moving up to ranking No. 182.
In the following week, invited as a wildcard to the ATP 250 in Santiago, Wild had his best campaign: he defeated Facundo Bagnis, Juan Ignacio Londero (world No. 63) and in the quarterfinals, the top seed of the tournament, and champion of the Rio Open, the Chilean world No. 18 Cristian Garín, who retired after losing the first set in a tiebreak. In the semifinals he defeated Renzo Olivo in straight sets becoming the youngest Brazilian to reach a final at this level, surpassing the achievements of former world No. 1 Gustavo Kuerten, then aged 20, and of Jaime Oncins and Thomaz Bellucci, at 21 years old. He also became the first Brazilian to compete in an ATP level final since Bellucci was runner-up in Houston in April 2017. In the final, he defeated Norwegian Casper Ruud (ranked No. 38 and champion of the Argentina Open two weeks before), in three sets, becoming the youngest Brazilian champion at 19 years old, surpassing Kuerten, who won his first ATP title at the age of 20.

After the defeat, Medvedev said of Wild that "if he keeps playing like this, he will be among the top 30 in the world." Next he defeated former top 20 Guido Pella to move to the third round of a Major for the first time in his career. In the third round, facing the 27th seed Japanese Yoshihito Nishioka, Wild was leading two sets to 1, but succumbed to fatigue, being eliminated in 3 sets to 2.
Competing as unranked in the post-Roland Garros Grass tournaments, Wild made his preparation and entered the Wimbledon qualifying tournament, while fighting for the No. 1 spot in Brazil, over Felipe Meligeni Alves and Thiago Monteiro. He defeated Jelle Sels and Pierre-Hugues Herbert, but in the last round of qualifying, faced Tomás Barrios Vera. At the beginning of the fifth and final set, he suffered a slight sprain in his ankle that cost him his place in the main draw of Wimbledon. Wild then decided to compete on clay in the Challenger in Karlsruhe, Germany.
After reaching the quarterfinals in Karlsruhe, and the semifinals of the Challenger 125 in Braunschweig, both in Germany, Wild became the No. 1 Brazilian tennis player for the first time, surpassing Thiago Monteiro, who spent five years in this position.

In the second round, Wild faced world No. 15, Karen Khachanov, and delivered one of his career-best performances by defeating him also in straight sets.

Wild also qualified into the main draw at the 2024 Miami Open following two qualifying wins, similar to his showing at the previous Masters in Indian Wells. He defeated Nuno Borges to record his first win at this tournament. In the second round, Wild faced 12th seed Taylor Fritz and won in straight sets, without a break on his serve to reach a second consecutive third round showing at a Masters level. In a 3-hour battle against No.23 seed Nicolás Jarry, where both served at a high level throughout the game, Wild came out ahead but was eliminated by 2 sets to 1.
