The arena hosted the 2025 World Men's Handball Championship with the country, Croatia and Denmark, including the final.

Fornebu was at the time undergoing an urban redevelopment; after several years of negotiations and public grants, Stabæk secured a lot in 2004.

Telenor Arena has hosted the Eurovision Song Contest 2010, as well as concerts by artists and bands of international fame, such as Madonna, Britney Spears, The Weeknd, Tina Turner, Adele, Muse, Olivia Rodrigo, Foo Fighters, Roger Waters (the Wall tour), Rihanna, Lady Gaga, Beyoncé, Jay-Z, Kanye West, Iron Maiden, Metallica, AC/DC, Black Sabbath, The Rolling Stones, Justin Bieber, Celine Dion and Drake.

Stabæk traditionally has played their home games at Nadderud Stadion, a municipal multi-purpose stadium at Bekkestua.

Following the club's rapid ascent from lower divisions to the top league during the first half of the 1990s, Nadderud became in need of upgrades, resulting in a new main grandstand opening in 1996.

[6] In November 2002, Borgarting Court of Appeal concluded that Norrønafly had the right to continue leasing a hangar—located at the planned location of the venue—until 2014.

[11] A new compromise was announced on 29 June 2004, whereby FB would give 50 million Norwegian krone (NOK) and a lot free to Stabæk in exchange for the commercial properties which would be part of the stadium.

They needed a 300 hectares (740 acres) lot which would have a market value of between NOK 60 and 80 million, and Reinsfelt stated that the municipality was willing to help by "maneuver in gray areas within the margins".

[23] In June 2008, Stabæk announced they had signed an eleven-year sponsorship agreement with the telecommunications company Telenor, where the latter would pay up to NOK 115 million for the sole naming rights for the arena, in addition to tickets and access to executive boxes.

Because of larger seating capacity, an all-seating arrangement, higher attendance and VIP facilities, Stabæk is able to generate three times the matchday revenue from Telenor Arena as Nadderud.

[26] The stadium is plagued with traffic problems on matchdays, with large crews hired to create temporary barriers to direct the crowds.

The bus stops closest to the venue are closed, and a large number of police officers have to direct the traffic.

[26] In October 2009, ten individuals bought the operation company of the club and signed a 40-year lease for the use of the arena for Stabæk's home matches, as well as the right to use the facility for certain other activities.

It was therefore difficult to secure lucrative events, as large parts of the year had to be held in reserve in case the venue was needed for yet-to-be scheduled matches.

[30] Stabæk's director of sports, Inge André Olsen, stated that returning to Nadderud was not an option, as it had too little capacity and insufficient facilities.

[31] Should Nadderud be used, it would have to be rebuilt, with new grandstands under roofs, VIP seating, a new parking house and new change room, which would cost NOK 100 million.

[34] On 4 December, Stabæk Fotball stated that they were willing to move their training, Norwegian Football Cup and UEFA matches to either Nadderud or Ullevaal, as a compromise to free up more available time in the arena.

[4] In mid-December, Stabæk Fotball started the process of a judicial registration of the right to lease the venue, which was permitted according to the contract.

Stabæk Fotball had until 30 June to accept the option, which would allow the club to remain at the venue on a permanent basis.

The club stated that they hoped they could remain at the stadium by establishing a foundation which could purchase the venue form Ulrichsen.

The federation was happy with the arena, and stated that were planning on using it for finals in their bid for future World and European Handball Championships.

[46] The venue has a considerably lower heating cost than similar conventional halls because the warm air is stored in the building's concrete and steel elements, and using the inert energy created by the spectators.

[46] The retailing area of 2,600 square metres (28,000 sq ft) in the complex is owned by Arena Handel AS, a subsidiary of KLP Eiendom.

[38] Ruter bus 31 is a high-frequency service which runs from the city center of Oslo via Lysaker Station to Fornebu.

[46] Stabæk's record attendance at Telenor Arena dates from 13 September 2009, when 13,402 people saw a league game against Rosenborg.

[52] The following list shows the average, maximum and minimum attendance for Stabæk's home games in the Premier League.

Other events at the venue include the Solberg Extreme Motorshow, Oslo International Horse Show[46] and Sensation.
