Olajide Olayinka Williams Olatunji, commonly known as KSI, is a British YouTuber, musician, and professional boxer who has taken the world by storm. Although he started his career behind the camera on YouTube, the multi-platinum musician has expanded his business empire over from the internet to the real world.

This led to KSI’s net worth exploding over the last few years to make him one of the most successful British entertainers in the world.

KSI’s Net Worth

KSI has a net worth of $50 million. This net worth is estimated based on his YouTube earnings, personal sponsorships, music royalties, and various business ventures. Despite being an opulent character, KSI has never disclosed his personal wealth in much detail.

This is common for many high-profile celebrities as they don’t want the added attention to their personal wealth. However, KSI did mention in an interview that he holds millions' worth of property and real estate assets in and around London.

After his first professional boxing match against Logan Paul, the British YouTuber also splurged on hundreds of thousands of dollars worth of diamonds and jewelry. While many justified this as a way to reduce his personal income tax in a pretty successful year, the ability to do this showcases the vast wealth KSI holds.

KSI has managed to break ground on new ventures both personally and professionally. The FIFA YouTuber broke out into the world of boxing with his first amateur exhibition with Joe Weller in 2018. This saw the entertainer successfully call out Logan Paul for a massive spectacle at the Staples Center in Los Angeles later that year.

Since then, he has made his professional boxing debut, released multiple record-breaking albums, and added millions to his ever-growing net worth.

This may make you wonder, where is KSI from? Where did he go to school? How did he meet the rest of the Sidemen? How much does he make every year? And how much he is worth?

Early Life

Olajide Olatunji, known as both KSI and JJ, was born in Watford, England. The YouTuber was born to Nigerian parents and spent most of his childhood in Watford, Hertfordshire and he completed his education at Berkhamsted School.

This is where he met his long-time friend and Sidemen co-founder, Simon Minter. While KSI was not particularly good at completing his schoolwork, he began expressing himself online as KSI. He registered a YouTube channel under the name KSI in 2009 and posted FIFA commentary videos.

Over the years, KSI diversified his content and started filming vlogs, gameplay videos, and videos with other creators. It was in these videos that KSI’s raw talent and personality began to come to light. The raw humor and over-the-top reactions managed to garner attention online, growing his YouTube channel to one of the largest individual channels in the United Kingdom, he has even made an entry onto the rap scene after releasing 4 EPs and even worked as an actor.

KSI has one younger brother, Deji Olatunji. Deji was born on December 9, 1996, and grew up with KSI in Watford. Deji also started his own YouTube channel shortly after his brother and has also managed to grow on the platform.

Deji was also part of KSI’s first exhibition fight against American YouTuber and entertainer Logan Paul. At this event, Deji went head-to-head against Jake Paul, who managed a technical knockout (TKO) in the fifth round.


KSI may have started on YouTube but has expanded his career and net worth over the last few years. Here’s a quick overview of how his career has progressed over the years.


KSI began his career on YouTube with video games commentary videos. Filming in his parent’s house in Watford, KSI filmed himself playing FIFA with his friends. KSI then expanded his content to include lifestyle vlogs and challenges with friends and family. His original channel was called JideJunior which appears to have come from his fathers name, Jide.

This growth led to him helping form the Sidemen with a few of his friends, a YouTube ensemble that ended up living in a house together where they would frequently film videos together. KSI naturally pivoted into a modern YouTuber and had the fanbase to attract sponsors and even successfully pitch a movie with fellow YouTuber Caspar Lee.

KSI managed to leverage his fame and popularity to produce and participate in a number of different films, documentaries, and even wrote a book detailing his rise to stardom. The comedian and English Youtube personality won vlogger of the year at the NME awards. His second youtube account JJ Olatunji, created in 2011 has also amassed millions of subscribers.


KSI always had a passion for music and used his platform on YouTube to launch his own music to the world. One of his first songs, Lamborghini, became an instant hit among his fans and helped him grow as an artist, rapper, and overall musician. KSI's album, Dissimulation, hit number 2 in the UK Albums Chart and many of his song feature strongly on the UK Singles Chart. Other popular songs of his include, Keep Up, Medusa, Madness, Millions, Little Boy, How It Feel, Houdini and Holiday.

Over the years, KSI has managed to evolve to the point where he released songs with Rick Ross, Lil Baby, Randolph, Lil Pump, P Money, Tom Grennan, Aiyana-Lee and even Anne Marie. KSI has always performed at concerts, festivals, and even on public television in the United Kingdom. He also managed to win awards for his music and is regularly noted among some of the best in the United Kingdom. Not Over Yet was his first release with new music label, Atlantic Records.

Professional Boxer

KSI entered the world of boxing back in 2018 with an amateur boxing match against long-time friend, Joe Weller. Hosted in Manchester, this event broke records for YouTube as one of the largest streaming events in history. KSI managed to TKO Joe Weller and claim his maiden victory in the sport of boxing. His first fight was a white-collar event but his next would be as a pro.

After winning the match, KSI took the opportunity to call out both Jake Paul and Logan Paul as his next opponent. Both American YouTubers went back and forth for a while but ended up agreeing to the boxing match scheduled for later in the year.

Logan Paul agreed to fight KSI while his younger brother Jake would face off against KSI’s brother, Deji. Jake managed to win his fight by TKO in the fifth round, but KSI and Logan drew their fight. This led to a rematch being scheduled for the following year in America.

The second fight was sold to DAZN and promoted by Matchroom Boxing. It was avaliable for pay-per-view fans and it generated millions in revenue. The fight was also a professional fight, with both KSI and Logan Paul both making their professional debuts at a sold-out Staples Center. KSI won the second fight by split decision.

Business Owner

KSI has made a number of investments over the years. While some have not turned out well for the British YouTuber, others are primed for success. The most recent venture was alongside Logan Paul with the launch of Prime Hydration.

This is a branded range of hydration and sports beverages that are available in both the United States and the United Kingdom. The business opportunity was initially brought to KSI by Logan Paul and has exploded ever since. Prime is now the official hydration sponsor for Arsenal Football Club in London.

KSI has also been known to invest heavily in real estate. Learning from his parents, KSI has consistently been putting money away by purchasing massive amounts of real estate in the United Kingdom.

The Sidemen

There have also been significant investments made through the Sidemen. This includes a clothing line under the same name that has been going strong for years and a fast-food restaurant chain that operates in multiple countries around the world.

The Sidemen have also launched a boutique Vodka brand, XIX Vodka. This was released back in 2021 after years of careful preparation and planning. The ensemble has managed to grow the Sidemen into a proper business with permanent staff handling the YouTube channel and exclusive content website, Side+.


KSI’s romantic relationships have been a well-kept secret for a very long time. While the name and identity of his most recent girlfriend are unknown, he did have a relationship with Seana Cuthbert for a number of years. The two were rumored to be dating from 2012 through 2014 when their split was made public on Twitter.


Having been one of the most prominent YouTubers in the United Kingdom, JJ has been friends with many other well-known characters in the industry. One of the most controversial friendships was that of Joe Weller who was close to KSI in the past.

KSI and Weller traveled together and were incredibly good friends that were even asked to write and perform a song for the Brazil World Cup back in 2014. However, tensions flared and they fell out, leading to the first YouTuber boxing event in February 2018.

While many thought that the friendship and preceding events were manufactured to sell the fight, interviews later proved that the beef was real. Words were exchanged during the buildup to the fight, with tensions hitting a peak at the Upload event when Joe shoved KSI on stage.

More About The Sidemen

The Sidemen is a collaborative YouTube ensemble that consists of KSI, Tobi Brown, Simon Minter, Josh Bradley, Ethan Payne, Vikram Barn, and Harry Lewis. KSI and Simon were childhood friends while Josh and Tobi attended college together. The group got to know each other through playing games online and filming content to post on YouTube.

While the group may have formed for commercial reasons, the entire ensemble are genuine friends. This is one of the main reasons why many agree that they are the most popular and successful YouTube groups on the platform.

One of the most entertaining and confusing periods for the Sidemen was back in 2017 when KSI announced that he would be leaving the group. He blamed his departure on Ethan Payne, who decided to write and release a diss track in retaliation.

This acted as a catalyst with Harry also releasing a song of his own along with many of the other Sidemen taking the opportunity to take a dig at KSI and other YouTubers. This was later revealed to be a massive joke, but it kept fans at the edge of their seats for weeks.


Olajide Olatunji's parents, Jide and Yinka, are from Nigeria. While he had a great childhood, the relationship he has with his family has not always been great. KSI grew up with his brother, Deji, and was instrumental in helping him grow his own presence on YouTube.

While KSI moved away from home to expand his career commercially with the Sidemen, Deji stayed at home with his parents. Despite multiple hour-long explanations posted by either brother, the real cause for conflict between the two is unknown.

Some claim that Deji publicized issues about KSI for attention online while others indicate that the dynamic has always been a bit off between the two.

Regardless, tensions were high back in 2018 when KSI was kicked out of the house on Christmas Day. This resulted in tons of tweets and recordings of the incident making the rounds online. This caused long-term tension in KSI’s family life, leading to years of awkwardness and headlines about him and other members of his family.

The Essentials of KSI
