2026 Results, Match by Match

Daihatsu Japan Open

Super 750・Tokyo Metropolitan Gymnasium

Seeded 3rd, he reached the last eight. He beat Toma Junior Popov (FRA) 21-17, 21-13 in 46 minutes in the first round on 15 July and Moh. Zaki UBAIDILLAH (INA) 21-12, 21-19 in 54 minutes in the second round on 16 July, then lost the quarter-final on 17 July 13-21, 17-21 to Koki Watanabe (JPN) in 54 minutes. 🔴The player who beat him went all the way to the final and finished runner-up.
🆕Added on 18 September 2026: the first and second rounds were on none of our pages, and until that day this page said we held only the quarter-final here. The official BWF day data and the draw on English Wikipedia agree on both. ⚡He met Toma Junior Popov again in the World Championships third round in August.

China Open

Super 1000・Changzhou, China

Seeded 3rd, he lost his first-round match (round of 32) 21-15, 17-21, 20-22 to Weng Hongyang (CHN). The decider went 20-22 — two points. This is a Super 1000, the top tier of the BWF World Tour.
🆕Corrected on 9 September 2026: we had written this one as "15-21, 21-17, 20-22", with the first and second games swapped. We confirmed it against the official BWF day data and the draw on English Wikipedia, and fixed our China Open page on the same day.

BWF World Championships 2026

World Championships・New Delhi, India

Seeded 4th. On the opening day, 17 August, he beat Dicky Dwi PANGESTU (AZE) 21-19, 21-17 in 51 minutes in the first round. In the second round on 19 August he beat Nhat Nguyen (IRL) 21-23, 21-19, 23-21 in 102 minutes, from a game down; our page for Alex Lanier records it as the longest of the 63 men's singles matches at this event. 🆕Added on 17 September 2026: that match was already on the Lanier page but missing from this one. We confirmed it against the official BWF day data and the draw on English Wikipedia. In the third round on 20 August he beat Toma Junior Popov (FRA, 15th seed) 21-17, 17-21, 21-14 in 78 minutes. The first and third rounds were on none of our pages either; we added them on the same day after the same two sources agreed. In the quarter-final on 21 August he lost 19-21, 15-21 to Kodai Naraoka (JPN, 10th seed) and went out in the last eight. 🔴That opponent also went all the way to the final and took silver.

China Masters

Super 750・Shenzhen, China

Seeded 5th. In the first round on 1 September he beat HU Zhe An (CHN) 19-21, 21-11, 21-16 in 85 minutes, coming back after losing the opening game. In the second round on 3 September he beat Kenta Nishimoto (JPN) 21-11, 21-9 in 36 minutes. In the quarter-final on 4 September he beat third seed Kunlavut Vitidsarn (THA) 18-21, 21-17, 21-18 in 101 minutes — again from a game down. 🔴In the semi-final on 5 September he lost 21-15, 20-22, 16-21 in 98 minutes to unseeded Jason Gunawan (HKG) and finished in the last four. He took the opening game, then lost the second 20-22. Gunawan had beaten Koki Watanabe in the first round and top seed Jonatan Christie in the second, and then won the title, beating fellow Hong Kong player LEE Cheuk Yiu 21-9, 21-16 in the final on 6 September. ⚠️The quarter-final and semi-final scores come from two agreeing sources — the BWF match data for that day and the draw on English Wikipedia; our own tournament page follows the Japanese entries, so it does not carry the quarter-final.

French Open 2026

Super 750・near Paris, France

Our French Open 2026 page lists him as the defending men's singles champion from the 2025 edition (October 2025, Glaz Arena). The title list on the English Wikipedia article also has the 2025 French Open, so this one is confirmed by two sources. The 2026 edition runs from 20 to 25 October. Whether he enters depends on the entry list.

Up to 6 September 2026 we record three matches between Antonsen and a Japanese player: one win and two defeats. (His 16-21, 21-16, 27-25 win over Yushi Tanaka in the Arctic Open final on 11 October is not in this count.) They sit on three different tournament pages, so until now they could not be read side by side. Put together, one thing is common to both defeats: the player who beat him went all the way to the final of that same tournament and finished runner-up.

• ❌17 July, Japan Open quarter-final: 13-21, 17-21 to Koki Watanabe, who finished runner-up at that tournament.
• ❌21 August, World Championships quarter-final: 19-21, 15-21 to Kodai Naraoka (10th seed), with Antonsen seeded 4th. Naraoka also went to the final and took silver.
• ⭕3 September, China Masters second round: 21-11, 21-9 against Kenta Nishimoto — his only win of the three, and the only one in straight games.

We do not write about why any of this happened. What is listed above is only the scores themselves, as recorded on our own tournament pages. All three opponents have a page on this site, so the same match can be read from the other side. This is not a career head-to-head — only the matches we recorded in 2026.

• 2025 — French Open — men's singles champion (Super 750)
  Our own French Open 2026 page lists him as the defending champion, and the title list on the English Wikipedia article also has the 2025 French Open — two sources agreeing.
• 2024 — European Championships — men's singles champion
  His Badminton Spirit career summary lists a 2024 European Championships title, and the medal table on the English Wikipedia article has gold at Saarbrücken 2024.
• 2023 — BWF World Championships — bronze (Copenhagen)
  Listed both in his Badminton Spirit career summary and in the medal table on the English Wikipedia article. He also won the Korea Open (Super 500) that year.
• 2019 — BWF World Championships — runner-up (Basel)
  Listed both in his Badminton Spirit career summary and in the medal table on the English Wikipedia article.
• 2024 — Malaysia Open, China Masters and Denmark Open titles
  According to his Badminton Spirit career summary he won the Malaysia Open (Super 1000), the China Masters (Super 750) and the Denmark Open (Super 750) that year, and was runner-up at the World Tour Finals and the Indonesia Open. ⚠️Badminton Spirit is the only source we have for this line.
• 2021 — BWF World Tour Finals — champion
  From his Badminton Spirit career summary. ⚠️Again a single source. The summary also lists a Denmark Open title in 2020.

His China Masters 2026 ended in the semi-final on Saturday 5 September, beaten by Jason Gunawan (HKG) — a player who had beaten Koki Watanabe in the first round and top seed Jonatan Christie (INA) in the second. 🏆Gunawan went on to win the title, beating fellow Hong Kong player LEE Cheuk Yiu 21-9, 21-16 in 43 minutes in the final on Sunday 6 September. The man who stopped Antonsen took the tournament.

🆕Antonsen won the Arctic Open 2026 (Super 500, Vantaa, Finland, 6–11 October) as the fourth seed. He beat qualifier Lee Zii Jia (MAS) 21-11, 15-21, 21-16 in the semi-final, and in the final on 11 October came from a game down to beat the unseeded Yushi Tanaka 16-21, 21-16, 27-25 (87 minutes), the deciding game going to extra points. The first seed was Kunlavut Vitidsarn (THA), the second Christo Popov (FRA) and the third Chou Tien-chen (TPE), the defending champion from 2025. ⚠️These two matches are not yet in the counts above (the twelve matches and the three against Japanese players, up to 6 September) (scores from Antonsen's side).

In the European autumn, our page for the French Open 2026 (Super 750, near Paris, 20 to 25 October) lists him as the defending men's singles champion.

⚠️ His home Denmark Open 2026 (13 to 18 October) is under way, but our tournament page follows mainly the Japanese players, so as of 15 October we have not recorded any Antonsen matches there. The French Open 2026 draw came out on 15 October, but our tournament page lists only the Japanese entries' first-round matches, so we have not recorded his place in the draw. We have not confirmed his entry for later events. We do not guess at names. The full calendar is on our 2026 badminton tournament schedule. Linked pages are in Japanese unless marked EN.

"Quarter-finals" tells you nothing about what happened to the player who beat you. In our records Antonsen's 2026 reads quarter-finals at the Japan Open, quarter-finals at the World Championships. But both players who beat him there — Koki Watanabe and Kodai Naraoka — went on to reach the final and finish runner-up. That pattern is only visible once player pages are wired to tournament pages.

🔴Our tournament pages follow the Japanese entries. That means a page about a player from another country has more gaps than one about a Japanese player. Until 18 September 2026 we held nothing before the Japan Open quarter-final. Where we hold nothing, we say so. The China Masters quarter-final, the first three rounds of the World Championships and the first two rounds of the Japan Open are not on our own tournament pages either, but the BWF match data for those days and the draw on English Wikipedia agree on every one of those scores, so we list them with the sources named. 🔎Two of the games we hold went 20-22 against him — the China Open decider and the second game of the China Masters semi-final — and a game that ends on 22 has to pass through 20-20, so that much follows from the final score alone.

🇯🇵Read alongside a Japanese player's page and the same match appears from the other side. On Koki Watanabe's page it is a 21-13, 21-17 win; on Kodai Naraoka's a 21-19, 21-15 win; on Kenta Nishimoto's an 11-21, 9-21 defeat. On Toma Junior Popov's page, the Japan Open first round and the World Championships third round are both defeats.
