In 2011, when originally budgeted, the cost of the construction of the new stadium was put at 35 billion Hungarian forints.[6]

On 26 June 2014, László Vigh said that the construction of the new stadium will cost 90-100 billion Hungarian forints.[7]

On 1 August 2014, the Nemzeti Sport Központ (the National Sports Center) presented the final vision of Hungary's new national stadium. The Hungarian architect György Skardelli, who was the designer of the nearby indoor arena, László Papp Budapest Sports Arena showed his original plans that did not include the demolition of the original stadium[8]

On 19 September 2014, UEFA selected Budapest to host three group stage games and one round of 16 game at UEFA Euro 2020. [9][10]

On 19 September 2014, Sándor Csányi, the president of the Hungarian Football Federation, said that the fact that Budapest can host UEFA Euro 2020 is a big achievement of the Hungarian sport diplomacy.[11]

On 23 February 2017, János Lázár, Minister of Prime Minister's Office of Hungary, said that the cost of the stadium will rise to 190 billion Hungarian forint from the previously estimated 100 billion.[12] The current budget of 190 billion Hungarian forints (EUR 610 million) is well over 100% of the original cost estimates and is far more expensive than similarly sized stadiums in Europe such as Allianz Arena in Munich or Arsenal's Emirates Stadium.[13]

In 2014, the original designs of the new Puskás Ferenc stadium was voted the best design by Stadiumdb.com which complimented the imaginative design which included an elevated running track that overlooked the pitch and had city skyline views.[14] However, by the time of construction two attempts at cutting unnecessary elements from the project scaled back the design to being football-focused because of the huge inflation of the construction budget and the desire to build a new athletics stadium in Budapest by Hungarian Prime Minister Viktor Orbán for a future Summer Olympics bid.[15][16]

On 29 June 2018, the Visitors' Centre of the Puskás Ferenc Stadium was opened. Balázs Fürjes, minister responsible for Budapest and its agglomeration, said at the opening of the centre that the new stadium would be more than a stadium. It would be a multi-purpose stadium that can hold concerts and conferences as well. He also said that preferably the stadium would host the 2021 UEFA Champions League Final.[17]

On 14 December 2018, the Hungarian Association of Journalists (in Hungarian: Magyar Sportújságírók Szövetsége) and the members of the communication department of the Hungarian Football Federation visited the construction.[18]

All of the seats were mounted by 2 October 2019.[19]

Cashless catering system was installed in the new arena. In the arena only touch cards or NFC are accepted.[20]

Only 500 parking spaces were created around the new stadium. Therefore, it is advisable to arrive at the arena by using public transport.
