KSI is a man who has maximised his career earnings and net worth through various different revenue streams. Whether it be YouTube, the Sidemen, boxing, music or his hydration drink Prime, KSI has made an absolute fortune throughout his career.

In this article we will take a deep dive into the career of KSI. This includes studying his net worth, career earnings and endorsement deals too. It’s safe to say ‘The Nightmare’ is one extremely rich man!

KSI Net Worth

KSI has fast become one of the most recognisable names in the world right now. The British celebrity shot to fame thanks to creating content on YouTube. In the beginning, KSI was recording videos of himself playing FIFA, before coming a more well known YouTuber as the years went on through vlogging and comedy-style videos and being the most popular member of The Sidemen.

Fast forward to today and not only is KSI one of the most popular YouTubers in the world, but he is also a talented musician, actor, entrepreneur and of course a successful boxer too.

KSI’s journey to fame started in 2009, when he started as a gaming YouTuber, playing popular games like FIFA. He amassed over 44 million subscribers on both his channels and became the 115th most-subscribed account on YouTube.

KSI was of course one of the founders of this whole YouTube/celebrity boxing scene after facing Joe Weller in an amateur bout back in February 2018. Since then, nobody could have imagined the sheer traction and popularity of celebrity boxing exhibitions.

As of today, it is reported that KSI’s net worth is roughly $30 million (sources: The Sun & The Mirror).

KSI’s estimated net worth of $30m is largely down to his career in boxing in recent years, but mostly thanks to being one of the biggest stars on the YouTube platform. Fighting the likes of Logan Paul on two occasions, as well as fighting Joe Fournier recently will certainly have helped boost KSI’s net worth.

Another reason KSI’s net worth is so high is down to his assets. ‘The Nightmare’ has a large collection of automobiles, all of which he enjoys driving. He is most in love with his stunning Aston Martin. He also owns a Bentley, a Jaguar F-type, and various other expensive vehicles.

In terms of real estate, KSI owns multiple properties all around the world. He owns a mansion in London which has a valuation of over $5 million. Not only that, but he also owns a three-storey house which is worth upward of $12 million. Both of these houses have more than five bedrooms, a huge lawn and a swimming pool.

This net worth figure of $30 million is likely to grow for the Brit as his career goes on too. $30m is possibly even an under estimation of KSI’s net worth, given the fact he is the co-founder of the Sideman and Prime Hydration, as well as continuing to make millions of dollars through boxing and YouTube.

KSI Endorsements & Business Ventures

Although the vast majority of KSI’s earnings comes from prize fighting and through YouTube, he also earns millions of dollar outside of the ring too. These vast endorsement deals and business ventures outside the ring are a big player in boosting KSI’s net worth and salary.

The 1993-born global figure of course launched Prime Hydration alongside former boxing foe and fellow YouTube star Logan Paul. In an interview back in February, KSI’s co-owner Logan Paul revealed that in the first year of the brand launching, they cleared over $250 million in retail sales (source: Essentially Sports).

Although this figure doesn’t reflect how much exactly KSI and his business partner Logan Paul will take home, it is sure to be in the tens of millions. Prime has also become one of the leading sponsors for Premier League soccer team Arsenal, Bayern Munich and Barcelona, as well as being the official drink partner of the UFC.

‘The Nightmare’ and ‘The Maverick’, once rivals, are now laughing as they rake in millions of dollars through their drinks brand. In the coming years, Prime could well rival some huge drinks companies such as Lucozade, Powerade and even Gatorade.

Besides Prime, KSI also endorses various brands like Adidas, XIX Vodka, Misfits Boxing, G Fuel, and several other multi-national brands. He is the CEO of Misfits Boxing and Co-owner of XIX Vodka and Sides Restaurant (source: The Sports Lite). No wonder KSI’s net worth continues to grow!

All in all, KSI earns a huge sum of money through his sponsors and endorsement deals. Of course, Prime Hydration seems to be leading the way by quite some distance now for KSI, alongside his foe turned friend, Logan Paul.
