Born in Ipanema, Rio de Janeiro, on 21 August 2006, Fonseca won the US Open boys' title in 2023 and finished that year as the first Brazilian junior world No. 1. He turned professional in 2024 instead of going to the University of Virginia, won the Next Gen ATP Finals that December as the lowest-ranked qualifier, and became the youngest Brazilian to win an ATP title at Buenos Aires in February 2025. He added the Swiss Indoors in Basel that October, the first ATP 500 singles title won by a Brazilian, and reached a career high of No. 24 in November 2025. At Roland Garros in 2026 he came from two sets down to beat Novak Djokovic. His 2026 grass season brought a first-round loss in Halle and a run to the Wimbledon third round as the 24th seed.

Halle 2024
Aged 17 and ranked 217th, he received a wildcard for his first tour-level grass match, against the qualifier James Duckworth. He hit 14 aces, six of them in the opening game, but faced break point after break point and lost 6-4, 6-4. He had warmed up for it at Challengers in Surbiton and Nottingham.

Before facing the British player Jacob Fearnley he had played only four tour-level matches on grass. He won 6-4, 6-1, 7-6 (5), the first 18-year-old to reach the second round since Carlos Alcaraz in 2021. "It's just a beautiful court. It's unbelievable, it's a dream," he said, adding that the key was to "work, believe, and dream".

Brazilian supporters arrived in their thousands, many in national shirts, and chanted his name through a three-hour win over Jenson Brooksby. He became the first Brazilian man in the third round since Thomaz Bellucci in 2010. Facing Chile's Nicolás Jarry next, he said: "I know Chile fans, they're loud. Yeah, the Brazilians are loud too."

In the third round in Paris he trailed Novak Djokovic by two sets and won 4-6, 4-6, 6-3, 7-5, 7-5, becoming the first Brazilian to beat Djokovic in singles and the first teenager to beat him at a major. The switch to grass was abrupt: two weeks later Yannick Hanfmann beat him 6-2, 6-2 in the first round in Halle.
