The record she broke belonged to the woman standing beside her on the podium. Chloe Kim won the women's halfpipe at PyeongChang 2018 at seventeen years and ten months — an age that had come to define what precocity looked like in snowboarding. Choi took the title roughly seven months younger. Kim had led after the first run in Livigno with 88.00 points and was the overwhelming favourite; errors in her later attempts left her with silver. The symmetry was not lost on anyone in the finish area. Choi had already taken one record from Kim three years earlier, and the second arrived on the largest stage the sport has.
That earlier record came at X Games Aspen in January 2023. Choi entered as a rookie, aged fourteen years and two months, and won the Women's Snowboard SuperPipe. She landed three different 900-degree rotations in the third of her four runs to overtake the two-time United States Olympian Maddie Mastro. The result made her the youngest SuperPipe champion in X Games history — again displacing Kim — and gave South Korea its first X Games gold medal in any discipline. She was a fourteen-year-old with no senior international pedigree, and she beat a field of professionals.
The pedigree, such as it was, had been assembled with unusual speed. In 2022, her first year of junior-level competition under the International Ski and Snowboard Federation, Choi went undefeated in the halfpipe. She won the world junior title. When she entered her first senior World Cup event, at Copper Mountain in Colorado, she won that too. There is a pattern in her results that is rare even among prodigies: she tends to win the first time she is allowed to enter something. It is a pattern that makes coaches nervous, because it offers no evidence about how an athlete responds to losing.
Milano Cortina answered that question directly. The Olympic final was, for two of its three runs, a disaster. The first crash was severe enough that officials paused to check whether she would continue; CNN, profiling her after the Games, traced a competitive history already marked by a fractured back and broken bones, and she arrived in Italy carrying the accumulated cost of a sport that punishes its best practitioners in the same way it rewards them. Sitting eleventh with one run remaining, she made a decision that most seventeen-year-olds do not make under that kind of pressure: she reduced her ambition.
Downgrading from 1080s to 900s and 720s was not caution. It was arithmetic. In falling snow, with a body that had already absorbed two impacts, the expected value of a clean lower-difficulty run exceeded that of a high-difficulty attempt she was unlikely to land. Judges reward amplitude, variety and execution as well as rotation count, and Choi's final run was tall, varied and flawless. The 90.25 that came back was the biggest score of the competition. It is a result that says as much about her judgement as about her ability.
She has spoken about the sport in terms that have nothing to do with records. "Snowboarding makes me feel free," she told Olympics.com in Milano Cortina — a plain sentence from an athlete whose public statements are consistently unadorned. For South Korea, whose Winter Olympic identity has been built almost entirely on short-track speed skating, her gold represents a genuine expansion of what the country believes it can do on snow. For the sport, it moves the age of the possible down again, which is what every generation of halfpipe riders has done to the one before it.
“Snowboarding makes me feel free.”— Choi Ga-on, speaking at Milano Cortina 2026
| Person | Country | Milestone | Age / Stat |
|---|---|---|---|
| Choi Ga-on | 🇰🇷 South Korea | Youngest Olympic halfpipe champion in history; Korea's first snow-sport Olympic gold | Age 17 |
| Chloe Kim | 🇺🇸 United States | Previous youngest Olympic halfpipe champion, PyeongChang 2018 | 17 yrs 10 mos |
| Red Gerard | 🇺🇸 United States | Youngest Olympic snowboarding gold medallist before Choi, PyeongChang 2018 | 17 yrs 5 mos |
| Maddie Mastro | 🇺🇸 United States | Two-time Olympian overtaken by Choi at X Games Aspen 2023 | Senior pro |
Olympic halfpipe finals are decided by a single counting run, which makes them a test of composure rather than of accumulated ability. Choi Ga-on failed the first two-thirds of that test in the most public way available — two crashes, a medical check, eleventh place of twelve with one attempt remaining — and then passed it by doing something counter-intuitive. She made her run easier. The judges reward execution and amplitude alongside rotation, and a clean simplified run in falling snow outscored every ambitious one attempted that day.
The age record matters for a second reason. Snowboarding's elite has been getting younger for two decades, and each new mark has been set by an athlete arriving fully formed rather than developing gradually. Choi is the clearest example yet: undefeated as a junior, X Games champion in her first appearance, World Cup winner in her first entry. What Milano Cortina added was evidence that she can also lose badly in the middle of a competition and still win it.
