The 2025 World Aquatics Swimming World Cup continued in Westmont on Friday, where a plethora of domestic and international talent is racing. That includes a large group off Europeans, headed by Swiss Olympian Noe Ponti.
The 24-year-old produced a time of 48.47 to get to the wall first in the men’s 100m butterfly final, establishing a new U.S. Open record in the process. Ponti trailed American Finlay Brooks through the first lap, but then took the lead after the first turn and never relinquished it.
Canadian Ilya Kharun hit a time of 49.00 as the silver medalist, while South African Olympic multi-medalist Chad le Clos rounded out the podium in 49.57.
With the swim, Ponti surpassed his own U.S. Open standard of 48.57, set just last week at the Carmel leg of the World Cup. Prior to that swim, the mark had stood at 48.63, set by American Tom Shields at the 2015 Duel in the Pool.
Ponti split 10.48/12.28/12.84/12.87 to establish the new standard, compared to his splits of 10.38/12.28/12.78/13.09 from last week. He was a tenth slower on the opening lap, identical on the second, 0.06 slower on the third, but came home 0.22 faster over the final length.
Splits Comparison:
| Noe Ponti | Noe Ponti | Noe Ponti | |
| New U.S. Open Record | Old U.S. Open Record | World Record | |
| 50m | 22.76 | 22.66 | 22.16 |
| 100m | 25.71 | 25.87 | 25.55 |
| Total Time | 48.47 | 48.53 | 47.71 |
Ponti already holds the world record in the event, having clocked 47.71 to win gold at December’s World Short Course Championships. His time on Friday ranks as the 10th-fastest performance in history. Because the United States doesn’t host a national championship in short course meters and rarely holds any meets in the format, most U.S. Open Records originate from either the 2019 International Swimming League season, the 2022 World Cup stop in Indianapolis, or older meets from the Duel in the Pool series.
He is slated to race the 50 fly and 200 fly later this weekend. In the 50 fly, where he holds the world record of 21.32, Ponti will look for his first win of the circuit after being outtouched by Kharun in Carmel. The 200 fly, meanwhile, is a likely scratch, as Ponti has not focused on that race over the past 18 months and withdrew from it just a week ago.
