Taylor Swift has been declared a billionaire by business news outlet Bloomberg, as a result of her re-recorded albums, worldwide Eras tour, and lucrative concert film. 

The outlet estimates 33-year-old Swift's net worth to be $1.1bn (£907.2m).

Her music catalogue since 2019 is worth an estimated $400m (£329.9m), ticket and merchandise sales from concerts have earned her $370m (£305.1m) while streams from Spotify, YouTube and other platforms are worth $120m (£100m).

Royalties from music sales come in at $80m (£66m) while the value of five properties she owns is $110m (£90.7m).

Bloomberg describes Swift as "essentially a multinational conglomerate with the world's most devoted customer base, its most charismatic CEO and significant economic power".

The outlet also predicts her wealth could be much higher, as its analysis is based only on assets and earnings that could be confirmed or traced from publicly disclosed figures.

The pop star has had one of the most prolific years in her two-decade career.

The Eras Tour, in which she revisits songs from her 10 albums in a three-hour show, spans 146 dates across five continents.

The Wall Street Journal reported that it is on track to become the biggest concert in history, with the potential to gross more than $1bn.

Swift will tour the show in the UK next year, visiting Edinburgh, Liverpool, Cardiff and London.

But she has already brought the tour to cinemas across the world earlier this month, where it earned $164.8m globally in its first two weeks and broke cinema records in the US and UK.

The re-recorded version of her critically acclaimed fifth album 1989 was also released today. The record, which was originally released in 2014, is expected to become one of the highest-selling albums this year.

She released the re-recorded version of her third album Speak Now in July in addition to her second album Fearless and fourth album Red, both re-released in 2021, after a dispute with music executive Scooter Braun.

After he sold the masters of her first six albums, allegedly without her knowledge, Swift embarked on an ambitious re-record of her entire back catalogue to regain control.

Swift also released several best-selling original albums in recent years - Grammy-winning folklore in 2020, evermore five months later and Midnights in 2022.
