The club was owned by Kolkata Games and Sports Pvt. Ltd. which consists of former Indian cricket captainSourav Ganguly, alongside businessmen Harshavardhan Neotia, Sanjiv Goenka and Utsav Parekh. Initially, for the first three seasons, Spanish La Liga club Atlético Madrid was also a co-owner; later Goenka bought the shares owned by Atlético Madrid.

In 2023, the club's name was rebranded as Mohun Bagan Super Giant.
In March 2014, it was announced that the All India Football Federation, the national federation for football in India, and IMG-Reliance would be accepting bids for ownership of eight of nine selected cities for the upcoming ISL, an eight-team franchise league modeled along the lines of the Indian Premier League cricket tournament.[5] On 13 April 2014, it was announced that Sourav Ganguly, Harshavardhan Neotia, Sanjiv Goenka, Utsav Parekh, and Spanish La Liga side Atlético Madrid had won the bid for the Kolkata franchise.[6] It turned out to be the most expensive franchise, being purchased for 180 million (around US$3 million).[6] On 7 May 2014, the team was officially launched as Atlético de Kolkata.[7]
The club played their first match on 12 October 2014 at home against Mumbai City FC in the opening ISL match.[13]Fikru Teferra scored the first goal in team and league history in the 27th minute as Atlético de Kolkata went on to win 3–0.[13]
On 5 June 2015, the team acquired Canadian international forward Iain Hume, whose five goals had helped Kerala to the final of the previous season.[17] In the second season's domestic draft, Atlético de Kolkata had the first pick, choosing Pune FCgoalkeeperAmrinder Singh for a fee of 450,000; their most expensive purchase was that of defender Augustin Fernandes for 2.6 million.[18] On 29 July, with García released due to his injury record, the team brought in Portugal international forward Hélder Postiga as their new marquee player; aged 32, he became the youngest such player in the league.[19] García's role as captain was taken on by his compatriot Borja.[20]
Postiga scored twice in Atlético's first game of the season, a 3–2 win at Chennaiyin FC, but was substituted later in the match due to injury, and missed the rest of the campaign.[21]Pelé, regarded as one of the greatest footballers of all time, watched the 2–1 win over Kerala at the Salt Lake Stadium on 13 October, Atlético's first home game of the season.[22] Hume scored two hat-tricks in November, in 4–1 wins against Mumbai City,[23] and FC Pune City.[24] The latter result made the team the first to qualify for the play-offs,[25] where they lost 4–2 on aggregate to Chennaiyin.[26]
In March 2016, it was reported that López Habas would leave the club due to concerns over his ₹23.5 million ($350,000) annual salary.[27] On 25 April, he left for Pune.[28] On 3 May, he was replaced by another Spaniard, former Villarreal manager José Francisco Molina.[29] Postiga returned to be the marquee again, but suffered another long-term injury early into the second game of the season. The club's ownership admitted that they had wanted a different marquee due to his record, but had been unable to sign one.[30]
Atlético de Kolkata finished in fourth place, taking the final position in the finals, and were drawn against first-place Mumbai in the semi-finals.[31] They hosted a 3–2 win in the first leg, with all goals in the first half, including two by Hume, and advanced with a goalless draw in the second leg.[32] In the final, away to Kerala on 18 December, Kolkata fell behind to a goal by their former player Mohammed Rafi, and equalised before half-time with a header by defender Henrique Sereno.

After the separation from Spanish club Atlético Madrid, most of the squad was not retained for the new season. On 14 July 2017, ATK appointed former England international striker Teddy Sheringham as their head coach for the upcoming season. While former Bengaluru FC head coach Ashley Westwood was appointed as the technical director for the club.[34] On 4 August, the team acquired former Irish international forward Robbie Keane as their new marquee player.[35]

The former Mohun Bagan AC head coach roped in some of his own former players who he had the experience of working with, along with former ATK players Arnab Mondal and Cavin Lobo.[39] They mainly focused on more local players and it served as the main foundation for building the squad for the season. Former Manchester United striker Steve Coppell was named as the head coach for the season.[40] Coppell had the experience of managing ISL clubs before such as Kerala Blasters FC and Jamshedpur FC. Under him the team finished 6th in the league, winning 6 games.[41]

Crest
On 7 July, the team's jersey and logo were unveiled by West Bengal Chief Minister Mamata Banerjee at the Nabanna building, temporary headquarters of the state's secretariat.[43] The logo featured a hybrid Bengal tiger–phoenix, with the latter element being symbolic of perpetuity, due to the footballing heritage in Kolkata.[44] Five stars above the crest symbolise the five owners of the club.[44] The shield is striped with tigers' stripes.[44]
The 85,000 capacity Salt Lake Stadium was the home ground of Atlético de Kolkata. The multi-purpose stadium, located in Salt Lake City (Bidhan Nagar), in the outskirts of Kolkata, is the largest stadium in the country. The Salt Lake Stadium is owned by the West Bengal State Government. Salt Lake Stadium, officially known as Vivekananda Yuba Bharati Krirangan (VYBK), is the largest stadium in India by seating capacity. Before its renovation in 2011, it was the second-largest football stadium in the world, having a seating capacity of 120,000. Prior to the construction and opening of Rungrado May Day Stadium in 1989, it was the largest football stadium in the world. The stadium hosted the final match of the 2017 FIFA U-17 World Cup, alongside hosting other matches of the tournament.
Atlético de Kolkata played their first two seasons at Salt Lake Stadium, but in the 2016 season, they had to move to Rabindra Sarobar Stadium due to the unavailability of Salt Lake Stadium, which was shortlisted as one of the venues for the 2017 FIFA U-17 World Cup. During the first season, Atlético de Kolkata has achieved an average home attendance of 45,172 per match and the most attended game of the season with 65,000 people.[45]
During the second season, 405,659 people attended the home matches of Kolkata (most by any club in that season) with an average of 50,707 per match, and they held the most attended game of the season for the second year in a row with 68,340 people.[46] During the third season, an average of 11,703 people per match attended the home matches of Kolkata.
The fourth season saw a formidable decline in the average attendance in the home matches of Kolkata due to the low capacity of Rabindra sarobar stadium. The lowest attendance count was 3,165 whereas the highest was 32,816. In their nine home games, ATK managed to pull an average attendance of just 12,629.
ATK, and the ISL in general, were initially announced with a mixed reception among football fans in Kolkata. Some locals feared that it could overshadow the development of players at the city's two long-established I-League clubs, while others saw the new franchise as a way to unite both sets of I-League supporters, who would be drawn together further by the involvement of Ganguly, who is idolised across the state.[47]
Ahead of the second season, the franchise accredited the ATK Fans Fraternity (ATKFF), whose ₹800 membership includes a home season ticket and an official jersey. The fraternity offered 4,000 memberships in an exclusive part of the stadium. Firstpost journalist Pulasta Dhar described it as a "brilliant" deal that could be replicated in order to help all ISL clubs fill their stadia.[48]
The club's initial sponsors were Indian telecommunications corporation Aircel, while its partners were Kolkata-based underwear brand Lux Cozi and insurance firm Apollo Munich.[49] In October 2015, Kolkata-based Birla Tyres agreed a deal to be the principal sponsors for the club's second and third seasons.[50]
