Top 30 Youngest Billionaires In The World Under 40

youngest billionaires in the world under 40

On 29 September 1916, John Davison Rockefeller was declared the world’s first billionaire. Born on a farm in Richford, New York, the famed American industrialist and philanthropist made the bulk of his fortune by founding The Standard Oil Company. Rockefeller was 77 when his status as one of the richest individuals in modern history was secured.

Ever wonder how old and how much are they worth considering being the youngest billionaires in the world?

In March 2019, Forbes estimated that there were 2,153 billionaires in the world. Earlier that month, the business magazine also generated widespread publicity – and some controversy – by announcing that celebrity-turned-cosmetics mogul Kylie Jenner, at 21, had become “The Youngest Self-Made Billionaire Ever.” Given her privileged upbringing and the sizable public profile that membership in the Kardashian family granted her, Jenner did not fit the mould of the “bootstrapper” – the rags-to-riches trajectory embodied by the likes of Rockefeller, Oprah Winfrey, and George Soros. And yet: Jenner was also not a “silver-spooner” – someone who simply inherited his or her wealth without doing much work.

As the rich get richer, they also seem to be getting younger and younger. Using data from Forbes’ real-time billionaires’ list, this article profiles 30 of the world’s youngest billionaires (as of March 2020) – and how they made it to the coveted $1,000,000,000 financial milestone. Few are genuine “bootstrappers” who attained their wealth despite being born into significant adversity and financial hardship, but many, like Jenner, had to contribute their share of inspiration and perspiration to outrank their peers and elders.

List Of 30 Youngest Billionaires in The World Under 40

1. Kylie Jenner (delisted)

Age: 23 years

Net worth: $1.0B

Kylie Jenner

Update June, 2020: As of latest coverage provided by Forbes, Kylie Jenner is no longer listed.

Jenner’s appearance on the cover of Forbes incited much debate about whether her wealth was truly “self-made.” Her long-time appearance on Keeping Up with the Kardashians (since 2007) undoubtedly helped her to achieve the stratospheric levels of social media fame (she has 165 million followers on Instagram) that helped Kylie Cosmetics, the company she founded in 2015, reach a valuation of $900 million in 2018. Coty Inc. specifically cited Jenner’s social media reach among Gen Z consumers as the reason for its acquisition of a 51% stake in Kylie Cosmetics (for $600 million) in November 2019.

2. Alexandra Andresen

Age: 24 years

Net worth: $1.3B

Alexandra Andresen
Frédéric Boudin, Ferd

The Norwegian heiress held the title of the world’s youngest billionaire from 2016 – 2018 (until Jenner made her billionaire debut). She is the youngest daughter of Johan Henrik Andresen, who is one of the richest men in Norway. As the owner of Ferd – a multibillion-dollar holding company with sizable real estate assets and partial ownership of companies like Swix, Elopak, and Aibel – he single-handedly made his daughters billionaires in 2007 when he transferred 42.2% worth of ownership stakes of Ferd to Alexandra and her sister Katharina. Alexandra is a professional equestrian with sponsorships from Kingsland and Samshield.

3. Katharina Andresen

Age: 25 years

Net worth: $1.3B

Katharina Andresen

Like her younger sister Alexandra, Katharina is one of the many European heirs that dominate this list of youngest billionaires. Despite her sizable 42.2% ownership stake in Ferd, her father Johan is still the main person responsible for its operations as a prominent investor in Norway. While he has publicly declared that he will not force his daughters to work in the family business, it appears that Katharina is more likely than Alexandra to eventually follow his footsteps. She studied social sciences at the Amsterdam University College and presently works at Brav – a Norwegian sporting goods company that is owned by Ferd.

4. Gustav Magnar Witzoe

Age: 27 years

Net worth: $2.6B

Gustav Magnar Witzoe

Witzoe inherited 47% of SalMar ASA – one of the world’s largest producers of farmed salmon – from his father in 2013. (Norway abolished its inheritance tax laws in 2014 – making it unlikely for other Norwegian billionaires to transfer ownership of family-owned corporations to their offspring to avoid hefty taxes). Fish farming may seem like a niche industry, but it is one of Norway’s largest industries. Apart from contributing to the family business, Witzoe has worked for MGM property and has attempted to make his own wealth by investing in real estate investing and tech start-ups.

5. John Collison

Age: 30 years

Net worth: $3.2B

Based in San Francisco, the financial technology company became the third-most valuable start-up in the United States in September 2019 when it attained a $35 billion valuation. Its payment processing operations involve hundreds of billions of dollars each year, with clients that include fledgling tech start-ups and tech titans like Uber, Lyft, Facebook, and Amazon. As of March 2020, Stripe has yet to undertake an initial public offering (IPO).

When his father Ludwig Georg Braun became the company’s CEO in 1977, it had $24 million in annual sales (this has increased to $8 billion in 2019). Ludwig keeps a low profile and has no social media footprint.

The old proverb “all roads lead to Rome” does not seem to apply to the world’s youngest billionaires. Most of them fall into two clear categories: self-made technology entrepreneurs (Kylie Jenner is an exception here) and “silver-spooners” who inherited significant stakes in multi-billion-dollar family conglomerates.
