The total seated capacity during ice hockey games is 13,349 (about 14,000 for basketball, for concerts up to 15,000) and as an amphitheatre, it is significantly reduced to between 3,000 and 5,000.

The formerly[1] Russian-owned arena has been unused since March 2022 due to EU sanctions related to the Russian invasion of Ukraine.

[5] Hartwall ended its sponsorship in March 2022, to avoid association with the then-Russian owners of the arena, Roman Rotenberg and Gennady Timchenko,[6] in the wake of the Russian invasion of Ukraine.

[5] In September 2024, the Finnish government announced that it would spend €200,000 on drafting a law that would allow the seizure of the arena from Rotenberg and Timchenko.

[7] That November, Rotenberg and Timchenko sold their ownership of the arena to Finnish real estate investment company Trevian,[1][8] with its CEO Reima Södervall along with Heikki Viitikko planning to have the venue reopened by early 2025.

Its assignment included hosting the gold-medal game, in which Kasperi Kapanen scored an Overtime goal to win Gold for Finland on home ice.
