Can Pan Zhanle be beat?
Pan Zhanle (-115) is one of only five men in 100m freestyle history to break the 47-second barrier. China’s 19-year-old phenom took six hundredths off Romanian David Popovici’s 2022 world record during his blistering 46.80-second performance at the World Aquatics Championships.
Despite breaking the record, Pan said, “My performance today wasn’t the best, and the result didn’t satisfy me. I feel like my performance was just average.”
During the third day of the 2024 European Championships in Belgrade, David Popovici won the men’s 100 freestyle in 46.88. This is the 3rd fastest performance in history, only 0.08 off Pan Zhanle’s world record from the 2024 World Championships. Who will win in Paris? pic.twitter.com/CppXiJECll

Could Popovici take gold?
David Popovici (+200) swam to the third-fastest 100m freestyle in history at the European Aquatics Championships in June. The 19-year-old Romanian’s time of 46.88 was just 0.08 outside of Pan’s world record and 0.02 off the personal best he set when becoming a double world champion at Roma 2022.
Jack Alexy (+600) took silver in the 100m freestyle at the 2023 World Aquatics Championships, swimming the race in 47.31 seconds. However, the 6-foot-7 American sprinter likely doesn’t stand a chance against Pan and Popovici.

O’Callaghan favored
Mollie O’Callaghan (+125) could win as many as six gold medals at this year’s Paris Olympic Games. The 20-year-old Australian captured the 100m and 200m freestyle titles at last year’s world championships in Fukuoka. She also looked in top-form while capturing first place at the Australian Olympic trials with a time of 52.33 seconds.

Haughey has a chance
Siobhan Haughey (+180) took home the silver medal in Tokyo in both the 100m and 200m freestyle events. The 26-year-old Hong Kong native ranks as the top swimmer in the world in the 100m after posting a time of 52.02 at the World Aquatics Swimming World Cup last October.
Best Longshot
While we like O’Callaghan (+125) to come out on top, don’t dismiss her countrymate Shayna Jack (+1000). The world silver medalist missed out on Tokyo after committing a doping infraction. But she finished just behind O’Callaghan at the Australian Olympic trials with a time of 52.75 seconds.
