American Swimmer Caeleb Dressel Sets World Record in 100m Butterfly
At the World Cup stop in Atlanta, Dressel swam 49.02 seconds, breaking his own 2021 mark of 49.45.
The Dressel era continues: the American has broken his own world record in the 100m butterfly
Main Event
On Saturday, June 13, 2026, at the FINA Swimming World Cup stop in Atlanta, Georgia, USA, an event occurred that once again confirmed: Caeleb Dressel is the absolute king of butterfly in the modern era. The 29-year-old American swimmer set a new world record in the 100m butterfly in a 50-meter pool, covering the distance in an incredible 49.02 seconds. With this result, Dressel broke his own achievement of 49.45 seconds, set at the Tokyo Olympics in 2021.
The race took place at the McAuley Aquatic Center, which hosted Olympic competitions back in 1996. Dressel, swimming in lane three in the penultimate fifth heat, took the lead from the first meters. At the 50-meter mark, he touched the wall in 23.11 seconds — 0.17 seconds faster than in his previous record swim in Tokyo, where the first split was 23.28 seconds. He covered the second 50 meters in 25.91 seconds, the best time in history for the second half of this distance.
The spectators in the stands greeted Dressel's finish with a standing ovation, realizing they had witnessed a historic moment. The scoreboard flashed 49.02, and a roar erupted through the arena — a new world record, improved by 0.43 seconds, which for a 100-meter swim is a colossal leap. Second place went to Canadian Josh Liendo with a time of 50.11 seconds, and third to Frenchman Maxime Grousset with 50.24 seconds.
Dressel himself did not hide his emotions after the race: "I felt great all week. The team did an incredible job, and today everything just came together perfectly. I knew that record was out there somewhere, and today I caught it. I dedicate this swim to my family and everyone who believed in me along the way."
Details and Statistics
Dressel's record (49.02 seconds) now separates him from the nearest pursuer in the all-time list by a full 0.43 seconds — a gap considered a chasm on a global scale. His previous record (49.45) stood for nearly five years, since July 31, 2021, when it was set at the Tokyo Olympics in a dramatic showdown with Hungary's Kristóf Milák. Interestingly, Milák also posted the best time of his career (49.68) but fell short by 23 hundredths.
To understand the magnitude of Dressel's achievement, one must trace the evolution of the world record in this event. Since 2009, when Michael Phelps set the record at 49.82 at the World Championships in Rome, 17 years have passed. In that time, the record has dropped only 0.80 seconds — first to 49.50 (semifinals of the 2019 World Championships in Gwangju), then to 49.45 (Tokyo 2020 Olympics), and finally to 49.02 (2026 Atlanta World Cup). Dressel has been the main beneficiary of this process, holding the three best times in history.
Below is a table of the progression of the world record in the 100m butterfly in a 50-meter pool:
| No. | Time | Name | Nationality | Date | Competition |
|---|---|---|---|---|---|
| 1 | 49.82 | Michael Phelps | USA | August 1, 2009 | World Championships, Rome |
| 2 | 49.50 | Caeleb Dressel | USA | July 26, 2019 | World Championships, Gwangju (semifinal) |
| 3 | 49.45 | Caeleb Dressel | USA | July 31, 2021 | Olympic Games, Tokyo |
| 4 | 49.02 | Caeleb Dressel | USA | June 13, 2026 | FINA World Cup, Atlanta |

As for Dressel's career achievements, he now holds five active world records in individual events: 50m freestyle (short course: 20.16, ISL, 2020), 100m freestyle (short course: 45.16, ISL, 2020), 100m butterfly (long course: 49.02, Atlanta 2026), 100m butterfly (short course: 47.78, ISL, 2020), and 100m individual medley (short course: 49.28, ISL, 2020).
Additionally, Dressel is part of US relay teams that hold world records in the mixed 4×100m medley relay (3:26.78) and the men's 4×100m medley relay (3:26.78). He is also the US record holder in the 50m and 100m freestyle, as well as the 50m butterfly.
To date, Caeleb Dressel is a 9-time Olympic champion (three in individual events), 15-time world champion, and 6-time short course world champion. He was the most successful athlete at the Tokyo 2020 Olympics, winning five gold medals, and is one of only seven athletes in history to win at least nine Olympic gold medals in a career.
Context and Significance
The record in Atlanta is not just another achievement in Dressel's long career. It is a landmark event that occurred at a time when many experts began to doubt his ability to return to peak form after a difficult period. In 2022, Dressel took a break from his career for psychological reasons, missing the World Championships in Budapest. His return to top-level sport was gradual, and only at the end of 2025 did he begin to show results close to his best.
It is also worth noting that 2026 is a pre-Olympic season. With only two years until the Los Angeles Olympics, this record sends a powerful signal to all competitors: Dressel has not just returned, he is faster than ever. His main rival on the international stage, Hungary's Kristóf Milák, who specializes in the 200m butterfly, also posts strong results in the 100m. However, their duel in Tokyo 2021 ended with the American's victory, and the gap of 0.23 seconds has only grown since.
For world swimming, Dressel's record is hugely significant. The 100m butterfly has always been considered the "signature event" of legendary Michael Phelps, who held the record from 2009. Dressel not only broke the achievement of his idol but pushed the bar so far that it could stand for many more years. Particularly impressive is that the American posted his best result not at the Olympics or World Championships, but at a World Cup stop — this shows he can produce record times on any given day, not just at major meets.
It is also important to mention that Dressel is one of the main contenders for FINA's "Swimmer of the Year" award. Given that 2026 includes the Short Course World Championships and the Pan American Games, the American has every chance to add several more gold medals to his collection and possibly update the record again. His main advantage is versatility: he is equally strong in all sprint freestyle and butterfly events, making him indispensable in relays.
What's Next / Next Event Announcement
After his triumph in Atlanta, Caeleb Dressel has no plans to stop. Already next week, June 20-22, the next FINA World Cup stop will take place in Santa Clara, California, where the American is entered in three events: 50m freestyle, 100m freestyle, and 100m butterfly. Given his current form, it is expected that he will attempt to break his other world records.
The main goal of the 2026 season for Dressel is the World Aquatics Championships, to be held in Budapest from June 18 to July 4, 2026. This tournament will be the main test of strength before the 2028 Los Angeles Olympics, and the American intends not only to confirm his status but also to add to his gold medal collection. Hungary's Kristóf Milák, who will compete at his home World Championships, will surely want to take revenge for past defeats.
As for preparation, Dressel has recently been training under coach Steve Jung. In May 2026, he spent a week at the University of Virginia, training alongside Gretchen Walsh — the women's world record holder in the 100m butterfly (her record is 54.33 seconds). This collaboration likely helped both athletes exchange experience and approach the June meets in optimal shape.
Editorial Forecast
Given Dressel's progress and his age (29 is the prime for a sprint swimmer), it is safe to assume he will not stop here. The American's physical attributes (height 191 cm, weight 88 kg) are ideal for butterfly, and his technique is considered exemplary. Key factors in his success are incredible starting speed and the ability to maintain pace on the second half of the distance, where most opponents slow down.
We believe that before the World Championships in Budapest, Dressel is capable of improving his record by at least another 0.2-0.3 seconds. Ideal conditions at the Danube Arena, where the tournament will be held (deep pool basin and high-quality water circulation system), could contribute to fast times. If the American can cover the first 50 meters in 22.9 seconds, the final time could approach 48.70 — something that recently seemed like fantasy.
Of course, competitors should not be discounted. Kristóf Milák updated the European record in this event in 2025, posting 49.50 seconds, while Canadian Josh Liendo (silver medalist at the 2025 World Championships) consistently swims under 50 seconds and also aims to make history. However, their main problem is an inability to maintain record pace on the second half of the distance, where Dressel excels.
We predict that in the next two years, we will witness an amazing rivalry in which Dressel remains the favorite. He is already a living legend, and his achievements (9 Olympic gold medals, 15 world titles) bring him closer to the status of "greatest sprinter in history." The question is whether he can surpass Michael Phelps's achievements (23 Olympic golds) — unlikely due to the difference in the number of events, but in sprint distances, Dressel has already surpassed his idol. The record of 49.02 in Atlanta is not just a number on the scoreboard; it is a statement that the Dressel era in world swimming is far from over.
