He faced Taipei's Chien Chia-Hung in his first fight, and scored a waza-ari, however won by ippon, as Chien was awarded a fourth shido for hansoku make. He then fought against Japan's Sho Tateyama in the next round, and neither could score. An was through to the quarter-final as he had one shido less. An managed to throw Hungary's Zsolt Gorjanacz for waza-ari, and it was enough to send him to the semi-final.

An faced France's Alexandre Mariac in the gold medal contest, and scored a yuko in just 15 seconds with one of his signature skills drop sode-tsurikomi-goshi. With a minute and half left, An threw Mariac for ippon with another signature skill single lapel morote seoi nage to win the gold medal.

2015 World Championships
"'I am so happy, I really can't believe it. I have to thank my coach and all of the team who have helped me to achieve this. I can't describe how I feel.'" After winning his first national title at the 2015 KJA National Championships, An was chosen to compete for Korea in his first senior World Championships in Astana. He came in ranked number 20.

An fought against Cuba's Carlos Thondique in Round 1, and scored waza-ari with a drop sode-tsurikomi-goshi. He again scored waza-ari with a drop single sleeve morote seoi nage for awasete ippon with 30 seconds to spare. In the second round, An competed against Belarus' Dzmitry Shershan. It was a close fight, with much of the action based on newaza. However, neither of them were able to pin or use successful submission techniques. An managed to score a yuko with a drop seoi nage effort to send him through to the next round. He attempted to use shime waza on Shershan in the dying seconds for ippon, but ran out of time.

In Round 3, An battled an experienced opponent in Kamal Khan-Magomedov. Khan-Magomedov was penalised thrice by the fourth minute, and had a glimmer of a score when he moved play to newaza and attempted an okuri eri jime before it was stopped by the referee as An escaped. An's dominance with the seoi nage shown again as he scored a waza-ari with the skill, and was enough to send him to the quarter-final. The stellar performance against the more established Russian earned him two thumbs up from coach Choi.

An was set against Uzbekistan's Rishod Sobirov in the quarter-final and again used reverse seoi nage to score a waza-ari. It was a close shido-filled fight, but An pulled through to enter the semi-final. An faced past opponent Pollack, and it was an even closer fight with no scores. An had initially scored a yuko with an ippon seoi nage, but was retracted by the referees. Despite earning a shido with one second left, it was still two less than Pollack, making him Korea's first finalist of the tournament. It was his fourth time winning against Pollack.

In the final, An faced Pulyaev, also a past opponent. It was the final with the most shidos, and the only one to end with a disqualification. An and Pulyaev were both level with 3 shidos each by the end of five minutes, and it went on to a minute of golden score until Pulyaev was penalised for being passive. An became one of the two world champions for Korea at the championships, the other being middleweight Gwak Dong-han. An said after claiming the World title, "I am so happy, I really can't believe it. I have to thank my coach and all of the team who have helped me to achieve this. I can't describe how I feel."

An also represented Korea in the team competition as the under 66 kg fighter. Korea battled against France in the third round, and An won against Larose, contributing to Korea's 5–0 win. In the quarter-final against Russia, An defeated Galstyan and Korea won 4–1, only losing in the half-middleweight bout. Korea was up against Georgia in the semi-final, and An beat long time rival Tomorkhuleg to set the tone for Korea. Korea won 4–1 again, with world champion Gwak supposedly losing on purpose to save energy for the final.

Korea had a much anticipated all-Asian final against defending champions Japan. The final featured reigning and former world champions across five weight divisions, namely An and Gwak for Korea, and Ebinuma, Riki Nakaya, Takanori Nagase and Ryunosuke Haga for Japan. An versus Ebinuma in the opening fight, and surprisingly lost by shido, alarming the Koreans. An Chang-rim managed to get the Koreans back by defeating Nakaya with a drop seoi nage effort, initially scoring waza-ari, then re-scored to ippon. Korea eventually lost 3–2, earning An Ba-ul a silver, and his second medal of the tournament.

2015 Grand Slam Abu Dhabi
An cemented his position as World Champion at his Grand Slam debut in Abu Dhabi. He fought Brazil's Gabriel Pinheiro in his first bout and the Brazilian was able to hold him off for more than half the fight. However, An brought the fight to the ground and secured a pin using kata gatame to koshi jime, earning a submission for ippon. In his second fight he went against Kazakhstan's Zhansay Smagulov. Smagulov attempted a drop seoi nage but got countered by An for waza-ari. An then used his signature drop morote seoi nage to score another waza-ari for awasete ippon.

An then faced rival Khan-Magomedov in the quarter-final and again defeated the Russian, this time with seoi otoshi. An's next fight was more difficult, against Germany's Sebastian Seidl. An's attacks were unable to penetrate Seidl's defense, therefore the match remained scoreless. With one shido less An was through to the final against rival and Olympic champion Galystan. The final was another close fight with both fighters unable to gain any scores. An was less defensive with two shidos less and won his first Grand Slam to complete a hat trick.

2015 Grand Slam Tokyo
An competed in his second Grand Slam in Tokyo and again faced Galystan in his first fight. He defeated the Russian by ippon this time, using a drop seoi nage for waza-ari, and then a tate-shiho-gatame for another waza-ari in the final minute. He surprisingly struggled in his second fight against another of his former opponents, local Tateyama. It was a close fight with only a shido between them. An lost, ending his tournament and continuing his medal-less streak in Tokyo.

2016 Grand Slam Paris
An's first tournament of the year was at his first Paris Grand Slam. He contested against Kazhakstan's Gabit Yessimbetov in the Round of 16, with both of them earning shidos for refusing to take a grip in the opening minute.

An then scored a waza-ari with four seconds to spare with ippon seoi nage to send him through to the next round.

An then faced Portugal's Sergiu Oleinic, and again was unable to score ippon.

2016 Grand Prix Dusseldorf
An entered his second Düsseldorf Grand Prix, traveling to the tournament with a top class Korean team. He faced Uriarte in the first round, and again couldn't attack successfully as the bout remained scoreless. An narrowly won by a shido, but soon regained form as he blazed through his following fights. He went against Israel's Baruch Shmailov, and took the lead with a yuko using his signature skill seoi nage. He ended the bout with an ippon using kouchi gari, sending him to the quarter-final.

An again faced former opponent, local Seidl in the semi-final. Although unable to score ippon, An still dominated the fight, scoring a yuko with a single sleeve grip seoi nage. He brought the bout to newaza, pinning Seidl in yoko-shiho-gatame for yuko before the latter trapped his leg. An eventually freed his leg before pinning again with yoko-shiho gatame for waza-ari prior to Seidl's escape. These scores for An were enough to send him to the final.

In the final, An faced rival Pollack in the fight for gold. An scored waza-ari with his signature drop seoi nage in the first 30 seconds and was enough to win the tournament. It was once again a good result for the Korea team, as An's gold was one of the five medals won by his national team. An ranked number one in the world with his win, one of the four Koreans to do so.

2016 KJA National Championships
An won his second national title and successfully qualified for the 2016 Olympics as Korea's half-lightweight representative. He successfully qualified as the number one ranked half-lightweight fighter in both the world and Olympic qualification rankings, and as the national tournament winner. He defeated his opponent in the final with sankaku jime for ippon. Tipped to be the one to beat for gold at Rio, An has said, "I'm obviously one of the best-ranked judokas in the world... people are expecting a lot of me. I wouldn't say that I'm not feeling the pressure, but I do feel very proud to be part of the national team."

2016 World Masters Guadalajara
At An's first invitation to the World Masters in Guadalajara, he was seeded number one. He faced Algeria's Houd Zourdani in his first fight, and won by ippon as Zourdani was disqualified for earning four shidos for passivity. He again fought Pollack in the quarter-final, but showed his superiority when he landed the latter on his back for ippon with his strong seoi nage in less than 20 seconds.

An battled another rival in Oleinic in the semi-final, and this time could not throw for ippon. He threw Oleinic with a drop morote seoi nage for yuko, and the no other throws were scored, sending him to the final. In the final he met rising star Tomorkhuleg for an anticipated match up, with the absence of Ebinuma. However, Tomorkhuleg had withdrawn due to injury, effectively giving the win to An via fusen gachi.

Continued podium streak and shock defeat at the 2016 Olympics
"I was on cloud nine... but I couldn't compose myself. I headed into the gold medal match in that state of mind. I failed to get a hold of myself and I think that's why I lost."

An came into the Olympic Games ranked first and was largely expected to take the gold in Rio. He was hailed by Korean media as one of the two predicted golds from judo at the Rio. In Round 2 he faced Kazakhstan's Zhansay Smagulov. He won by waza-ari through seoi nage, and sealed the win awasete ippon with a juji-gatame. He continued his ippon streak in the third round with another waza-ari with seoi nage, and then landed his opponent from France, Kilian LeBlouch, with sode-tsurikomi-goshi flat on his back.

An faced a challenge in Rishod Sobirov in the quarter-final. Both of them were penalised with shido for defensive posture in the beginning of the bout, and An sealed his place in the semi-finals with a seoi nage for waza-ari. His fight against long-time rival Masashi Ebinuma of Japan was reminiscent of the Japanese bout at the 2012 Olympics against An's countryman and coaching staff Cho Jun-ho.

After being deadlocked with a shido each in regular time, the bout went into golden score. It was vital for both An and Ebinuma to win as neither Japan nor Korea has had a gold medal after two days of competition. An attacked first with a reverse seoi nage on a single sleeve grip but failed to score. Ebinuma would then attempt a drop double sleeve seoi nage, again to no score. Ebinuma again attacked with a drop ippon seoi nage, only to get countered by An with tani otoshi for yuko, effectively ending the bout with a win to An. An then celebrated with Ebinuma clinging to him, becoming a parody among the Korean judo community.

An faced lesser known Fabio Basile in the final. Basile had been playing ippon judo throughout the tournament, but was considered a surprise finalist. However, An and Basile had contested in the past, notably at the 2016 Paris Grand Slam. In just over a minute, Basile had scored ippon against An with the latter's signature skill, seoi nage. This would result in Korea's second medal in judo after Jeong Bo-kyeong's silver in the extra-lightweights. There would then be numerous media coverage about Basile causing one of the biggest upsets in Olympic judo as An was the world champion, world number one and heavy favourite to win the title.

2016 Grand Slam Tokyo
An returned to competition at the Grand Slam in Tokyo. Basile was also competing at the IJF's top circuit tournament continuing their budding rivalry. After winning by awasete ippon with two seoi nages, An lost in the quarter-final against Japan's Yuuki Hashiguchi when he was disqualified for hansoku make because of a waki gatame, in which An attempted a dangerous ippon seoi nage with an incorrect grip. Despite qualifying for the repechage, An did not compete therefore handing his opponent the win with fusen gachi. The rematch with Basile did not occur as neither fighters made the finals.

Fighting style
An is known for his tactical and methodical style of judo, that has evolved since his junior career. An is right-handed but has a left-sided grip. He is also noted for his seoi nage, being trained by technician and World and Olympic champion Choi Min-ho. His most often used variation is the drop morote seoi nage. An has been praised for his versatility on nage to ashi waza combinations, as well as efficient newaza. Some of his most commonly used combinations include seoi nage to kosoto gake and kosoto gari to seoi nage.
