Odds from Sportzino
The defending Olympic champion Caeleb Dressel is the favorite to win the Olympic men’s 100m butterfly final this weekend. But he is by no means a heavy favorite to get the job done. There are six swimmers at +1000 or shorter odds to get the job done and win gold in this event. That includes Milak, who Dressel was able to hold off with his world record swim in the 2021 Olympic final in this event.
Olympic Men’s 100m Butterfly Major Storylines
The rematch between Dressel and Milak is going to be box office stuff in the men’s 100m butterfly final, assuming both men make it to the final. Milak nearly won the 200m butterfly final before being caught in the final 50m by France’s young star Leon Marchand. But Milak was the class of that race over the first 150m, which should have him feeling good about his rematch with Dressel here.
Other than that, the wide-open nature of this race is a huge storyline, as we could see some decent names miss out on the final entirely depending on where they are set up in the prelims and semifinals. Lane positioning will be so important in the races leading up to the final, so bettors will want to keep an eye on who ends up in which spots before placing their bets on anyone to get the gold in this race.
Olympic Men’s 100m Butterfly Medal Contenders
There are around six swimmers who could easily come away with a medal in this event. Dressel and Milak are two of those swimmers. They are joined by Canada’s Joshua Liendo, Switzerland’s Noe Ponti, France’s Maxime Grousset, Australia’s Matthew Temple. Liendo took silver in this event at the 2023 World Championships, while Ponti won bronze behind Dressel and Milak in this event in the Tokyo Games in 2021.
Men’s 100m Butterfly Betting Prediction: Kristof Milak (+700)
With the Olympic men’s 100m butterfly being as wide open as it is, we are going to go with Kristof Milak to win gold at +700. Milak should qualify in a good place for this final and end up in one of the four inside lanes, which is huge in a pool that has been brutal on the outside lanes. Look for the Hungarian to get off to a fast start in another butterfly race and to avoid blowing the lead like he did in the 200m butterfly final.
