The idea of building a new arena in Prague came on the heels of the "golden era" of Czechice hockey: winning the gold medal at the 1998 Winter Olympics and three gold medals in a row at theIce Hockey World Championships from 1999 to 2001. The arena's main backer then became Sazka a.s., a Czech betting company.
The construction of the arena (which began in September 2002) was not without issues, but it was opened in March 2004 as Sazka Arena, in time to host the2004 Men's World Ice Hockey Championships.[3] In March 2008, the building was renamed O2 Arena.[4]
In March 2011, Sazka filed for insolvency due to debts from building the arena and other problems.[5][6] Sazka was then re-organized and financially stabilized.
From its opening until 2015, it was home toHC Slavia Prague of theCzech Extraliga. Slavia won the national championship on home ice in Game 7 of the 2008 Extraliga finals againstHC Karlovy Vary 4–0 in front of a then-league-record crowd of 17,117. For two seasons, 2012–13 and 2013–14, O2 Arena also hosted occasional home games ofHC Lev Prague of theKontinental Hockey League. The club played its home games of the2014 Gagarin Cup Finals at O2 Arena, attracting the three largest crowds in league history.[7] In 2015, Slavia was relegated to the 1.liga, and the club chose to move back to the smaller Zimní stadion Eden, the team's former home and current training centre. In its place, O2 Arena reached an agreement with cross-town rivals Sparta Prague on 24 June 2015. Sparta ownership cited the need for significant renovations atTipsport Arena as the main reason for the move.[8]
In 2015, O2 Arena co-hosted the IIHF World Championship with ČEZ Aréna in Ostrava for the second time. This time, the tournament re-established the record for World Championship attendance, which stood until being surpassed in 2024 with the tournament held in the same two cities.[9]
In 2017, it hosted the 1st edition ofLaver Cup international indoor hard court men's tennis tournament between Europe and Team World.
In 2019, a multifunctional congress centre,O2 universum, opened up next to the Arena.

In 2021, the Stages Hotel with capacity of around 600 people, opened right next to the Arena.[11] This included a creation of a big pedestrian zone and renewed public space around the eastern entrances to the arena.
On 6 & 7 September 2006Madonna performed there during herConfessions Tour. The concert was attended by 18,628 spectators, the biggest number of spectators in the arena's history.
