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 an already competitive field? Let’s dive into the details.
The 2026 Pro Swim Series in Austin, held from January 14-17, 2026, at the Lee and Joe Jamail Texas Swimming Center, has already made waves. With the event taking place in a long course meters (LCM) pool, swimmers are pushing the limits of speed and endurance. For those eager to follow the action, the Psych Sheet (updated), How to Watch guide, Live Results, and Live Recaps are all available online. Speaking of recaps, don’t miss the detailed breakdowns of the Prelims and Finals from each day—trust us, you won’t want to skip these highlights.
In the Men’s 50m Butterfly Semifinals, Grousset’s record-breaking swim wasn’t just a personal triumph—it was a statement. Let’s put this in perspective: the World Record stands at 22.27, held by Ukraine’s Andrii Govorov since 2018, while the American Record is 22.35, set by none other than Caeleb Dressel in 2019. Dressel’s previous US Open Record of 22.84, set in 2022, seemed untouchable—until now. And this is the part most people miss: Grousset’s 22.81 not only surpasses Dressel’s mark but also solidifies his position as a top contender in the event.
The Top 8 Qualifiers for the Final include familiar names like Van Mathias (23.46) and Dressel himself (23.50), who finished third in the semifinals. But Grousset’s lead of over half a second is no small feat. It’s worth noting that Grousset already holds the French National Record in the 50 fly with a time of 22.48, which he achieved at the 2025 World Championships in Singapore. Could this be a sign of even greater things to come?
Here’s where it gets even more intriguing. Just yesterday, Grousset told SwimSwam, ‘I will beat the time of Caeleb, I hope,’ specifically referencing the 100 fly. While he hasn’t tackled that event yet, his performance in the 50 fly suggests he’s not just talk. Is Grousset the next big name in sprint butterfly, or will Dressel reclaim his throne? Let us know your thoughts in the comments.
For those keeping score, here’s a quick rundown of the key records:
- World Record: 22.27 (Andrii Govorov, 2018)
- World Junior Record: 22.96 (Diogo Matos Ribeiro, 2022)
- American Record: 22.35 (Caeleb Dressel, 2019)
- U.S. Open Record: 22.81 (Maxime Grousset, 2026)
- Pro Swim Series Record: 23.09 (Ilya Kharun, 2025)
As we look ahead to tomorrow night’s final, one thing is clear: Maxime Grousset is a force to be reckoned with. But will his record-breaking swim spark a rivalry with Dressel, or is this just the tip of the iceberg? What do you think—is this the start of a new dynasty, or a one-time upset?
