Chloe Kim, a two-time Olympic snowboarding champion, failed to secure her third consecutive gold at the 2026 Winter Olympics after falling on her final runs. She was overtaken by 17-year-old Choi Ga-on of South Korea, who scored 90.25 on her last attempt. Kim, 25, had led after her first run but fell twice in her final attempts, ending with silver.
