Hold onto your swim caps, because the world of competitive swimming just got a whole lot more exciting! Maxime Grousset has shattered Caeleb Dressel’s US Open Record in the 50-meter butterfly, clocking an astonishing 22.81 at the 2026 Pro Swim Series in Austin. But here’s where it gets controversial—is this the beginning of a new era in sprint butterfly, or just a fleeting moment in the spotlight? Let’s dive into the details.
The 2026 Pro Swim Series – Austin kicked off with a splash from January 14-17, 2026, at the iconic Lee and Joe Jamail Texas Swimming Center. This long-course meters (LCM) event brought together some of the fastest swimmers in the world, all vying for glory. For those who missed the action, you can still catch up with the Psych Sheet, How to Watch, Live Results, and Live Recaps available online. And trust me, you’ll want to see how the drama unfolded across the prelims and finals of all three days.
In the Men’s 50m Butterfly Semifinals, Grousset didn’t just break a record—he made a statement. His 22.81 swim edged out Dressel’s previous US Open Record of 22.84, set back in 2022. But this isn’t Grousset’s first rodeo; he already holds the French National Record in the event with a blistering 22.48, which he achieved at the 2025 World Championships in Singapore. And this is the part most people miss—Grousset had hinted at his ambitions just a day earlier, telling SwimSwam, “I will beat the time of Caeleb, I hope,” specifically referring to the 100m butterfly. Yet, he delivered in the 50m instead, leaving Dressel in third place with a 23.50.

Grousset’s lead of over half a second heading into the final is significant, but swimming is a sport where milliseconds matter. Can he hold onto his momentum, or will Dressel—or another contender—stage a comeback? And let’s not forget the broader context: with Andrii Govorov’s World Record of 22.27 (2018) and Diogo Matos Ribeiro’s World Junior Record of 22.96 (2022) still standing, how close are we to seeing these records fall?
Controversy Alert: Some argue that Grousset’s rise challenges the dominance of swimming powerhouses like Dressel. Others believe this is just a blip in Dressel’s illustrious career. What do you think? Is Grousset the future of sprint butterfly, or is this record just a stepping stone for Dressel’s eventual return to the top? Let us know in the comments below!
