who owns the o2 arena

The O2 Arena in London is currently owned (via a long-term 999‑year lease) by pensions insurance specialist Rothesay , while it is owned and operated on a day‑to‑day basis as a venue by AEG Europe.

Who owns the O2 Arena?

• In 2025, Cambridge University’s Trinity College sold the long-term lease of The O2 Arena to Rothesay, a major UK pensions insurance firm, for around £90 million.

• That deal gave Rothesay a 999‑year lease, making it the long‑term owner of The O2 Arena site in financial and property terms.

• The arena itself, along with the “Up at The O2” rooftop walk, is owned and operated as a live entertainment venue by AEG Europe, part of the global AEG (Anschutz Entertainment Group) organisation.

So, in simple terms:

• Rothesay = long‑term leaseholder/financial owner of the property.
• AEG Europe = owner–operator of the arena as a business and events venue.

Mini sections and extra context

How ownership changed over time

• The structure started life as the Millennium Dome and struggled as an exhibition venue before being reimagined as The O2, opening in its current form in 2007.

• Trinity College Cambridge became a major landlord for the site in 2009, acquiring it for a reported £24 million, then later auctioned its long‑term lease, which Rothesay won in 2025.

Who actually runs shows there?

• The concerts, sports events, and other shows people associate with “The O2” are programmed and managed by AEG Europe, part of the larger AEG group, a leading global sports and entertainment operator.

• AEG handles ticketing, event operations, and venue management, while Rothesay’s role is primarily as the long‑term institutional owner of the lease, seeking stable investment returns.

Why you see so many different names

• The O2 brand you see on signs is due to a naming-rights sponsorship; the telecom company pays to have its name on the arena, renewed in a multi‑year deal in 2017.

• Behind that branding, AEG Europe runs the arena business, and Rothesay now sits in the background as the long-term leaseholder, with the shopping/entertainment district partly owned through a joint venture with Crosstree Real Estate.
