Biles finished with an all-around total score of 119.750. She fell once on the vault while trying to come out of her signature Yurchenko double pike.
That cost her a one-point deduction and marked her first fall of the season.
The win on Sunday came after Biles rolled through the field at the U.S. Classic last month to win the all-around title. Skye Blakely finished in second place with a 113.850.
Biles is getting back into the swing of things in the lead up to the Olympics later this summer after she both led Team USA to the team title at the World Gymnastics Championships last fall and earned The Associated Press’ Female Athlete of the Year award in 2023.
Though she will still go through qualifying later this summer, Biles is sure to be one of the most-followed athletes in the world in France for the Olympics.
It will mark her first games since she experienced the "twisties" at the 2020 Olympics in Tokyo and sat out multiple competitions in what was a stunning development for the four-time Olympic gold medalist.
