In the women’s final, South Korea’s world number one An Se-young beat Japan’s Akane Yamaguchi 21-17, 21-14 for her second world crown.
But it was history for French badminton, after the 21-year-old Lanier beat Japan’s Kodai Naraoka 21-11, 21-11 in a lopsided men’s final at New Delhi’s Indira Gandhi Indoor Stadium.
World number 10 Lanier smashed the winner as he jumped in delight and hugged his coach before standing on the podium for his gold medal.
“I think definitely today was a day for French badminton and it was a day for the whole staff also,” Lanier said after the triumph.
“Today it was a day for France, and when the mixed won, everyone was happy, and I just thought that I needed to give them a double smile, double moments, and I needed to make history again.”
The finalists went toe-to-toe until the mid-game interval of the opening game with 2025 European champion Lanier leading 11-9.
The brawny Lanier, whose parents are professional sailors, then hit the gas to open the gap and take the opener in 23 minutes with a lethal combination of attack and defence.
“I showed to Kodai that I could play that speed, and also I could play that long for like two hours or even more,” said Lanier.
“I mean, I was definitely ready. Now I feel sore and tired but on court I felt more energised, and I trusted my fitness.”
Lanier kept up the momentum in the second game to take five straight points in an 8-3 lead.
World number 11 Naraoka fought back with his power game but soon lost steam to a fitter and inspired Lanier, who beat world number two Kunlavut Vitidsarn and Victor Lai en route to the final.
The women’s title clash was much closer with last year’s winner Yamaguchi giving it her all in a fast-paced battle between number one and two.
Yamaguchi’s returns and jump smashes entertained a large Sunday crowd, but An had answers to everything with her attacking and baseline play.
Reigning Olympic champion An, who won her previous world title in 2023, secured the win in 49 minutes and let out a scream and raised her hands to celebrate.
“There were lot of fans supporting me and that keeps me going and gives me energy,” said An, who came into the tournament pulling out of last month’s Japan Open with a foot injury.
Yamaguchi, with a silver, became the first women’s singles player to claim six medals at the showpiece event.
