O2 signed a record £200 million agreement to keep the naming rights for the London venue, the O2. This ten-year contract extends O2's association with the venue until at least 2038.

The partnership with Anschutz Entertainment Group (AEG) is thought to require O2 to pay approximately £20 million annually. This current arrangement represents an increase of nearly 50% over the annual payment under the previous deal.

Last year, the O2 hosted a total of 239 events. The venue first opened in June 2007 with a performance by Bon Jovi.

Paul Samuels, president of global partnerships at AEG International, stated, "Everyone thought it would never work, that it was crazy building on the site of the Millennium Dome, it was considered the biggest white elephant." Samuels added that "People will opt to save money on other things but still want to go out and spend money on live entertainment."

A major element of the deal involves a 50% rise in the number of priority tickets allocated to O2 patrons. Through its Priority Tickets programme, O2 sells over 1.7 million tickets each year across the twenty music venues it sponsors in the UK.

Financial results for 2025 showed O2 revenues climbed 14% to £148.6 million. Furthermore, the company's pre-tax profits surged by 18% in 2025, reaching £76.5 million.

The record year allowed the payment of a £27.5 million dividend to its US parent company.
