Born in Metz on 26 June 1998, Humbert entered the French federation's national centre in Poitiers at 12 and lost about 18 months of his junior career to growth-related injuries. A left-hander who takes the ball early, he won his first ATP titles in 2020 at Auckland and Antwerp, and has seven in all, including Marseille in 2024 and 2025 and Dubai in 2024. He reached No. 13 in April 2024 and that autumn played the Paris Masters final, losing to Alexander Zverev. He has played Davis Cup for France since 2023 and won both his singles rubbers against Hungary that year. His 2026 grass season brought a semi-final at Queen's, the Eastbourne final and a first-round defeat at Wimbledon by Zizou Bergs, the man who had beaten him in that final days earlier.

In his first grass final he broke Andrey Rublev for 5-3 and took the first set at the fifth attempt. The second went to a tie-break without a break point on either side; at 4-4 a Rublev backhand error gave him the mini-break, and he finished with a forehand winner, then lay down on the court. He had beaten two top-10 players, Alexander Zverev and Rublev, in one week.
After a five-set opening win over Thomas Martin Etcheverry, he beat Casper Ruud, then in the top 10, 3-6, 6-2, 7-5, 6-4. It was his first win over a top-10 player at a Grand Slam. David Goffin ended the run in four sets in the third round.
After a poor grass season in 2023 he admitted he had been getting too wound up in the warm-up events. At Halle in 2021, he said, "I just went for it, I hit." On a surface where his left-handed serve and backhand made him awkward to play, he reached the fourth round again. As a boy he had watched Wimbledon admiring Roger Federer.
He beat Jack Draper 7-5, 6-3 on his 28th birthday and the crowd sang to him afterwards. "By far it's the best gift I could have today," he said. "It's nice to see Jack back on court." Celebrations were modest, with a final the next day: "No big party, but France is playing so I'll be watching the match."
He won the first set of the Eastbourne final against Zizou Bergs, who came back after a rain delay to win 3-6, 6-1, 6-4 for the first ATP title on grass by a Belgian man. The Wimbledon draw then paired them again in the first round. Humbert, the 27th seed, levelled from two sets down, but Bergs took the fifth 6-3.
