Political authorities, chess legends, and prominent members of the Hungarian Olympic movement and the sports administration expressed their unconditional support for the event.

It was announced to be a "green" Olympiad with the possibility of transfers between the venues and the hotels using bicycles and electric vehicles, as well as avoiding the use of paper and plastic.

In order for the competition to run smoothly without any disturbances, the number of visitors per shift was limited to 100, and they had to place their mobile phones and prohibited devices in the cloakroom.

Before the start of each round, all players and team captains had to undergo scanning before entering the playing venue, and all forbidden items (electronic devices and complex bags bigger than A4 format) had to be placed in a designated area.

[21] The torch relay began in India, which hosted the previous Chess Olympiad, and passed through eleven countries: Canada, Colombia, France, Georgia, Ghana, Kazakhstan, Morocco, New Zealand, Romania, Switzerland, and the United Arab Emirates.

The ceremony ended with a video tribute to all participating countries, which featured their names and flags shown one after another with songs performed by Kouchak and Vincze in the background.

Some of the players who were involved in this project included Alina Kashlinskaya, Nana Dzagnidze, Yuliia Osmak, Aster Melake Bantiwalu, Rauha Shipindo and Nolwazi Nkwanyane.

United States' team, consisting of Fabiano Caruana, Wesley So, Leinier Dominguez, Levon Aronian and Ray Robson as a reserve player, had the highest average rating of 2757.

The squad consisted of the challenger in the World Chess Championship 2024 Gukesh Dommaraju on board one followed by R Praggnanandhaa, Arjun Erigaisi, Vidit Gujrathi and Pentala Harikrishna.

[45] China had the third highest average rating of 2727 with reigning World Champion Ding Liren playing on top board, followed by Wei Yi, Yu Yangyi, Bu Xiangzhi and Wang Yue.

[45] Hungary's first team had the ninth highest pre-tournament average rating and were stronger for Richard Rapport, who returned to play for his native country three months before the Olympiad, and Peter Leko.

[53] On the road to the gold medal, they defeated the United States, Hungary and China, and were held to a draw only by Uzbekistan in the ninth round.

[58] The challenger in the World Chess Championship 2024, Gukesh Dommaraju of India, achieved the highest rating performance of 3056 in the Open event after scoring 9 out of 10 points (eight wins and two draws) on board one.

The team was led by Alina Kashlinskaya, who won the first leg of the FIDE Women's Grand Prix 2024–25 in Tbilisi, and also included Monika Soćko, Aleksandra Maltsevskaya, who changed federation, Oliwia Kiołbasa, who scored the best individual performance at the previous Olympiad, and Alicja Śliwicka.

[34][65] Despite the fact that China was missing all four top players—Hou Yifan, Ju Wenjun, Tan Zhongyi and Lei Tingjie—the young team was still competitive and were seeded in fourth place with an average rating of 2416.

[34] Ukraine as defending champions were fifth seeds and were severely weakened by the absence of Anna and Mariya Muzychuk, who were both among the top ten rated players in the world.

In their absence, the team was led by Yuliia Osmak on board one followed by former World Women's Champion Anna Ushenina, Nataliya Buksa, Inna Gaponenko and Evgeniya Doluhanova.

[34][66] India justified their role as pre-tournament top seeds according to the average rating and won the gold medal in the Women's event with a total of 19 match points, having recorded nine wins, one draw and one loss.

Roberto Rivello (Italy) was re-elected as Chairman of the Constitutional Commission without opposition, while Erald Dervishi (Albania), Ian Wilkinson (Jamaica), Marouane Tabti (Algeria) and Ivy Claire Amoko (Uganda) were elected as members out of a total of six candidates.

[86] In this regard, a series of awards was announced to recognise individuals and organisations who had significantly contributed to the development and promotion of chess throughout the past century.

FIDE President Arkady Dvorkovich said that these awards would hopefully "inspire future generations to take up chess and bring the game to new heights".

[92] Singer Juga released the song "Queen Trap" with just lyrics promoting female empowerment and sorority, and produced a music short film in co-production with FIDE Commission for Women's Chess.

The filming took place at the Museum of Fine Arts during the rest day of the Olympiad, on 17 September, and it brought together female chess players from 160 countries, including Judit Polgár, Alexandra Kosteniuk, Elisabeth Pähtz, Bibisara Assaubayeva and Tania Sachdev amongst others.

[96] Official partners and sponsors for the Olympiad included Tech Mahindra, Coca-Cola HBC Hungary, Chessable, Freedom Holding, the Judit Polgar Chess Foundation and Dorko.

[135] Magnus Carlsen arrived ten minutes late for his game against Colombian grandmaster Roberto Garcia Pantoja in the third round as he had been travelling by bike in the rain, rushing to the venue and was confused about the entrance.

[138][139][140] A disallowed device was detected in the match between Bosnia and Herzegovina and Thailand in the fourth round of the Open event, in which Dejan Marjanović initially lost his game against Tinnakrit Arunnuntapanich, but the score was reversed after the anti-cheating control had been performed.

[144] In the match between Israel and Bangladesh in the tenth round in the Open event, Bangladeshi grandmaster Enamul Hossain forfeited his game against Tamir Nabaty.

He announced his boycott in a post from his Facebook profile and complained about Israel's participation due to the ongoing conflict with Palestine by referring to the non-participation of Russia and Belarus.
