Taylor Swift has been dethroned as world's youngest self-made billionaire

Although she might still be the wealthiest woman in the music industry, Taylor Swift has just been dethroned in another department.

The singer, 35, has also held the title of world's youngest self-made female billionaire since 2023 - but it's now been bestowed upon another ridiculously successful girl boss.

Thanks to the earnings from her worldwide Eras Tour and the value of her music catalogue, Swift achieved billionaire status by the age of 33, according to Forbes.

Her net worth is believed to be a whopping $1.6 billion, about $600million of which is believed to have been accumulated through royalties and touring, while she also has about $125 million in real estate.

Swift also used to have the claim to fame of being the world's youngest self-made female billionaire, which some people might reckon is priceless.

But tech tycoon Lucy Guo has now swiped that title from her, having sorted herself a bank balance similar to the world's biggest pop star three years faster than Swift, Forbes has reported.

The 30-year-old is the co-founder of Scale AI, a California-based data annotation company which provides labelled data used to train artificial intelligence applications.

Guo, who studied computer science before dropping out of college in favour of a fellowship, was just 21 when started the firm with Alexandr Wang, then 19, back in 2016.

She handled the operations and product design teams at the San Francisco firm, while Wang acted as CEO - and two years later, the pair of them had made the Forbes' 30 Under 30 list.

Guo later left Scale AI after a reported disagreement with Wang regarding how it was being run, as she later explained in a statement: "We had a difference of opinion but I am proud of what Scale AI has accomplished."

She kept hold of her stake in the business though, which is believed to be around five percent - and thanks to a deal which is currently being wrapped up, the value of this slice has boomed.

Scale AI is finalising an offer which allows early employees and investors in the nine-year-old company to sell shares to new or returning investors, Forbes says.

It's set to be complete by 1 June and the company will then reportedly shoot up in value to a whopping $25 billion, which is an impressive 80 percent jump since this time last year.

As a result of all of this, Forbes estimates that the entrepreneur's stake will now skyrocket to $1.2billion, allowing her to boot Swift out of the top spot.

It is believed that Guo's total net worth will be $1.25 billion, when incorporating her stake in her second startup firm, Passes, too.

This makes her a member of an enviable club which only half a dozen women on the entire planet are in - ladies who have become self-made billionaires before hitting 40.

Guo previously revealed she had an 'incredibly frugal' upbringing, telling Fortune that she continued to 'live cheaply' well into her adult life until she had 'made her first $10million'.

She reckons that's the best way to be, as she explained in 2023: "Be frugal and always live below your means.

"A lot of people up their lifestyles when they start making more money, which causes them to not save as much. The more money you save, the more you can invest, which compounds over the years.

"Your network is your net worth."
