Kingsbury continued his breakthrough season with one more World Cup event win and 5 additional medals, finishing the 2010–11 FIS Freestyle Skiing World Cup season 4th overall and 3rd in the moguls discipline, behind countryman Alexandre Bilodeau and winner Guilbaut Colas. In the midst of this season, he competed in his first 2011 FIS World Championships, and began with a bronze medal in the moguls event behind Bilodeau and winner Colas. In the dual moguls event, Kingsbury fell in the final pairing, again finishing behind Bilodeau, this time for the silver medal. Reflecting on his first World Championships, Kingsbury stated: "I never thought at the beginning of the season that I'd be able to be two times on the podium at Deer Valley, the hardest course in the world. Alex, since I was young was my example to follow, it's awesome to be in the final against him."
