Part 1: Aquatics, Archery and Badminton Olympic Betting Odds

Winning an Olympic Gold Medal is one of the greatest achievements in sports, an honor only a select group of athletes will experience. The Summer Olympics are usually filled with historic medal-winning moments on the field and around the world. 

In this seven-part series, we will look at every sport in the Tokyo Summer Olympics, diving into the reigning champions and the odds to win gold for each nation. As usual, having a little something on the events should make it more exciting, so we’ll also give enough information to help anyone make intelligent bets online

These Olympics will have 33 sports, with multiple gold medal opportunities in each, while some sports have multiple disciplines. In addition to the traditional Summer Games sports like Swimming and Soccer, five new sports and fifteen new events will debut in Tokyo this summer. 

The International Olympic Committee (IOC) has proudly stated that there was a concerted effort to give these games a “youthful” appeal and increase female competition. No longer being delayed by the COVID-19 pandemic, the IOC is moving forward full-steam with the 2020 Summer games in Tokyo. So make sure to keep up with odds, scores, and updates for everything in Tokyo in our Olympic Sportsbook

First up: Aquatics, Archery, and Badminton


Aquatics in the Summer Olympic Games is made up of five different disciplines. There will be two different medal events for artistic swimming, eight different medal events for diving, two different medal events for water polo, two different medal events marathon swimming, and 35 different medal events in swimming. 

This is a sporting category in which Team USA traditionally does exceptionally well and an essential collection of events to watch when you are betting on medal specials. We like the USA, but watch out for Australia.

Russia's Natalia Ishchenko and Russia's Svetlana Romashina

Artistic swimming 

Oddsmakers have marked the Russian women as favorites in both of the artistic swimming events (a.k.a. synchronized swimming). Russian duet powerhouse Natalia Ishchenko and Svetlana Romashina are the defending Gold Medal champions and will be looking to make it two consecutive Olympics titles. And they are the clear favorites to do just that; the Russian artistic swimming duet is -900 in the online sportsbook, with the defending Silver-medal team from China at +400. Host country Japan is defending the Bronze medal and should not be overlooked to upset at +1000.

The money lines are similar in the team artistic swimming event, and the top three teams are the same, with Ishchenko and Romashina at -1200 in the Olympics Sportsbook. Next in line is China at +500 and Japan at +1200. It looks like China should pick up some medals in the sport, but Russia is a safe bet for Gold, as they continue to dominate artistic swimming. Never underestimate the power of home-field advantage, however, and keep your eyes on the Japanese.


Diving is usually where China makes its move in the medal markets of the Summer Olympics. 

At the 2016 Summer Olympics in Rio de Janeiro, China absolutely dominated diving, with Chinese divers winning gold in seven of the eight competitions. The country is the reigning gold medal champion in men’s 3m springboard, men’s 10m platform, men’s synchronized 10m platform, women’s 3m springboard, women’s 10m platform, women’s synchronized 3m platform, and women’s synchronized 10m platform. The only gold they missed was men’s synchronized 3m springboard, which Great Britain won, while China took the bronze. 

In Tokyo’s upcoming 2020 Summer Games, the Olympic odds depict a similar story of total Chinese dominance. China is -400 in women’s synchronized 3m springboard, -300 in women’s synchronized 10m platform and -350 men’s synchronized 10m. 

In the only 2016 competition, although China did not win gold in men’s synchronized 3m springboard, they are clear favorites this time around -200. Although it is the defending Gold Medalist, Olympic oddsmakers have Great Britain at +200. A Chinese athlete is the favorite in all four individual diving competitions. Chen Yuxi is -150 in the women’s 10m, Shi Tingmao is -170 in the women’s 3m, Xie Siyi is -170 in the men’s 3m, and Yang Jian is -125 in the men’s 10m. 

Were you looking for Team USA in Diving?  The best online betting sites have Team USA +1000 in women’s synchronized 10m and men’s synchronized 3m. 

Netherland's Sharon Van Rouwendaal holds her gold medal after winning the Women's 10km Open Water Swimming

Marathon swimming

Marathon swimming is an Olympic event where athletes race ten kilometers in open water. The Dutch swept marathon swimming in the 2016 Rio Olympics, with Sharon van Rouwendaal winning Gold in the women’s competition and Ferry Weertman winning Gold in the men’s competition. 

On the men’s side of things, it is defending bronze medalist Marc Antoine Olivier from France, who is one of the best Olympic bets in this summer’s marathon at +230. Right behind him is German newcomer Florian Wellbrock at +280, and men’s defending gold medalist Ferry Weertman from the Netherlands’ odds to win gold is a bit longer at +325. Sharon Van Rouwendaal will be back in Tokyo to defend her gold medal, but she is seen as an underdog and has +500 odds in the Olympic Games sportsbook. 

The favorite to win gold in the women’s 10km marathon swim is Chinese swimmer Xin Xin at +250. She is coming off of winning gold at the 2019 World Championships in Gwangju. Rachele Bruni of Italy is the defending silver medalist, and oddsmakers have her +500 for Tokyo. Poliana Okimoto of Brazil, who won bronze in Rio, won’t be in this summer’s Olympic Games.


In men’s swimming, things feel more open than ever now that Michael Phelps has retired. Team USA star Ryan Murphy is the defending gold medalist in 100m and 200m backstroke, but the Olympic Men’s Swimming odds show him as an underdog in both events at +185 in the 200m and +300 in the 100m. 

British swimmer Adam Peaty is -2000 in men’s 100m breaststroke, Hungarian Kristof Milak is -800 in 200m butterfly, and Russian Evgeny Rylov is -350  in 200m backstroke. USA’s Caeleb Dressel is a staggering -1200 in 100m butterfly.

On the women’s side, American Katie Ledecky was a huge winner in the 2016 Rio Summer Games. She won gold in the 200m freestyle, 400m freestyle, 800m freestyle, and 4×200 m freestyle relay. Things do not look as sure for Ledecky in Tokyo, where she is +375 in the 200m and +190 in the 400m, behind Australian Ariarne Titmus, who is the favorite in both events. Ledecky is the clear favorite in the 1500m and 800m women’s freestyle, however, with online Olympic odds of -400  in both events.

The pool has traditionally been a great place for Team USA to make headway in the Olympic medal markets. This year, Australia has a women’s team built for championships. Team USA will defend its gold medal in the 4×200 m freestyle relay, and the odds for the American women to win are +300. That makes the returning champs underdogs to the Australian women who are favored by 5 to 1.

The Australian women are also a staggering -1400 to defend their gold in the 4×100 m freestyle relay, with defending silver medalist Team USA at +450. The 50m women’s freestyle should be another entertaining race. There is a four-way jam for the best odds with Emma McKeon and Cate Campbell at +300 and Sarah Sjostrom and Ranomi Kromowidjojo +350. None of these swimmers medaled in this event in Rio.

Water polo 

Olympic oddsmakers have Hungary +250 and the narrow favorite in men’s water polo at the upcoming Tokyo 2020 Summer Olympics. This is noteworthy, as Hungary did not even medal in the 2016 Summer Olympics in Rio. Serbia, who took home the gold medal in 2016, is looking to defend its title and the nation has the second-best money line at +280. Croatia won silver in Rio 2016 and is +400 in these Olympic Games. 2016 bronze medalist, Italy, is +550 on the men’s side. 

On the women’s side of Olympic water polo, it is all Team USA. The American women brought home gold in Rio 2016, beating Italy 12-5 in the gold medal match. The Russians just slipped past the Hungarians in the bronze medal match 19-18. 

Team USA looks like a certainty to defend their gold medal in women’s water polo in the Tokyo Olympics 2020 with a -450 moneyline. The Italian women did not even qualify for Tokyo, and the Russians do not look like a contender in this Olympiad. Spain could be an underdog with some value at +600.

In addition to the four typical competitions in Olympic archery (women’s individual & team, men’s individual & team), a mixed team event will debut in the Tokyo Summer Olympics. South Koreans swept the competition in Rio 2016, winning gold medals in all four events. They are again favored to do so in both team events, -160 in men’s and -125 in women’s. Team USA, the defending silver medalist in men’s team archery, is +250, and Russia, the defending silver medalist in women’s team archery, is +1000. 

Sticking with team events, in the debut of mixed team competition, South Korea is again favored in the Tokyo Olympics odds at -275. On an individual level, both defending gold medalists, Ku Bon-chan in men’s and Chang Hye-jin in women’s, will not be competing in Tokyo. 

Defending bronze medalist American Brady Ellison is the favorite in the men’s individual. South Korean Kang Chae young and Indian Deepika Kumari, both of who did not medal in Rio 2016, are neck and neck favorites in Tokyo.

It will be interesting to see who takes home gold in each of the badminton events. Kento Momota from Japan is the men’s singles favorite at +115, but he did not medal in Rio 2016. Defending silver medalist Viktor Axelsen from Denmark has the second-best line at +500. Our Olympic expert picks defending gold medalist Chen Long at +900 for one of his most valuable Olympic bets.

Fu Haifeng and Zhang Nan from China won gold in men’s doubles in Rio but won’t be in Tokyo. Instead, the favorites are Marcus Fernaldi Gideon and Kevin Sanjaya Sukamuljo from Indonesia at +350. The Japanese duo Takeshi Kamura and Keigo Sonoda are at +500. It’s a whole new field in men’s doubles Badminton. 

The field in women’s singles is also wide open. The defending gold medal champion Carolina Marin from Spain won’t be participating in Tokyo, and the defending silver medalist, Pusarla Venkata Sindhu from India, a staggering +1400. In somewhat of a reversal, Nozomi Okuhara, the defending bronze medalist, is a more respectable +550. The Olympics sportsbook has Chinese player Tai Tzu Ying +170 as the favorite in women’s singles. 

Gold in women’s doubles is projected to go to a Japanese team, with Mayu Matsumoto & Wakana Nagahara and Yuki Fukushima & Sayaka Hirota at +175 and +300, respectively. 

Badminton Mixed doubles also feature a relatively new field in the sportsbook. The defending gold medal-winning team from Indonesia and bronze medal-winning team from China are not in Tokyo. Malaysians Chan Peng Soon and Goh Liu Ying, who won silver in Rio 2016, are longshots at +1800. At a solid -115, Zheng Siwei and Huang Yaqiong from China are your favorites in mixed doubles. 

Olympic best bets 

These real time betting lines can be both surprising and expected. While many of these Olympic Games will feature a new champion and nations will celebrate a new hero, many of us will be looking to find the value while enjoying the nonstop action. These Olympic games should be exciting to watch with events new and old, but we will make it even more fun by having a little extra on the winners.
