YouTube Career

KSI created his first YouTube channel JideJunior in April 2008. Today, the channel has over 107,000 subscribers. On the same date of the channels creation, KSI uploaded his first video called LOOKING THROUGH SPACE. The video is a school project he made with his friend Patrick.

After that video appeared on YouTube, KSI began uploading FIFA and rap videos onto the channel. KSI uploaded his last video onto the JideJunior channel in March 2009, later abandoning it in 2011.

Creation of "KSI"


KSIOlajidebt Vlog's - The History of my Name

On 24 July 2009, KSI created his official YouTube channel. At the beginning of his YouTube career, he only uploaded gaming videos to his channel (mainly FIFA and Modern Warfare 2). On 15 August 2011, he released his first vlog titled KSIOlajidebt Vlog's | The History of my Name, which was the first video he revealed his face in, and explained the meaning of "KSI". The video today has over 2.6 million views.

Following that video, KSI continued to upload FIFA, but would also upload more vlogs and sketches. His FIFA videos were also becoming more comedy-oriented, mixing various skits into the videos.

Creation of "KSIOlajideBT"

On 26 January 2011, KSI made his second YouTube channel called "KSIOlajideBT". The purpose of the channel was to solely upload gaming videos (in order to make the KSI channel a vlogging channel). KSI did not upload a video to this channel from early 2017 until 31 December 2018. This channel is currently KSI's main YouTube platform where he uploads reddit and gaming videos, although it is now named 'JJ Olatunji'.

The Sidemen

Main article: The Sidemen

On 29 October 2013, KSI joined The Sidemen along with Miniminter, Behzinga, Zerkaa and TBJZL. The Sidemen were officially formed (as we know them today) once W2S and Vikkstar123 joined the group.


Until 2013, KSI was good friends with fellow YouTuber GudjonDaniel. The two created a lot of videos together on both of their channels, KSI even created Daniel's YouTube channel on 9 April 2010. The two drifted apart after KSI realised Daniel was simply using him to promote his own channel. In a KickTV interview with Daniel, the interviewers asked him if he plays FIFA with KSI. He replied with "Who the fuck is that?".

After this incident, KSI took to Twitter to express his opinions. The two stopped collaborating and Daniel ended up getting a lot of hate for many years until he quit YouTube a few years later. In early 2018, the two tweeted a picture of themselves together announcing that they made up and that their 'beef' had officially ended. It had taken nearly half a decade.


As the Sidemen continued to grow, so did KSI. Before the group had formed, he was still an prominent online figure in the U.K. and was notable for his "Get Hyper" and "Heskey Time" videos (both of which were popular in British schools at the time).

KSI had made/has been featured in many videos with all of the Sidemen. Prior to their formation, he used to make many videos with Simon (whom he has been friends with since Year 8), Callux and more. He was always the most subscribed member of the Sidemen; closely followed by W2S.

His most viewed video made with the Sidemen is the CROSSBAR CHALLENGE, which currently sits at over 55 million views. He also made collaborations with a lot of other famous British YouTubers at the time such as Caspar Lee, Joe Sugg, Calfreezy and Callux. Today, the KSI channel sits at 22.5 million subscribers, and over 5 billion views. His second channel, JJ Olatunji, sits at 12 million subscribers and over 2 billion views.

Around 2014, he made multiple videos for the sporting company Rule 'Em Sports, where he'd take part in various challenges and activities with other YouTubers and celebrities.

KSI Army

The KSI Army was the general name for the fans of KSI, especially towards the beginning of his YouTube career. This name was popular during KSI's first peak in popularity from 2009 to 2011 but has significantly decreased in usage in recent years. His current fans, or newer fans, are most likely unaware of the term.

Music Career

KSI branched out into "rapping" around the same time the Sidemen formed. On the 26 October 2016, KSI embarked on his first European music tour, where he performed in the U.K., France, Germany, Netherlands and Belgium.

Due to certain fans complaining that KSI's music career had "taken over" his main YouTube channel, he decided to activate a VEVO channel. This has 3 videos and around 500,000 subscribers as of August 2017. KSI's VEVO channel, as of 2021, is unused with his official music videos being posted on his main channel.

No Sleep

Main article: Jump Around

A new single titled Jump Around was released on 16 September 2016. The song features American rapper Waka Flocka Flame and samples the song Jump Around by House Of Pain. However, the single failed to make an impact on the UK Singles Chart.

KSI released his second EP titled Jump Around on 28 October 2016. However, the EP failed to make an impact on the UK Albums Chart.

Boxing Career

KSI V Joe Weller

Main article: KSI V Joe Weller

When Joe Weller won his first amateur boxing fight in August 2017, KSI offered himself as his next opponent. After multiple press conferences and videos surrounding the "drama" that had arisen between the two, their official fight was confirmed.

On 3 February 2018, KSI and Joe Weller contested in an amateur boxing match at the Copper Box Arena in London, England. KSI defeated Joe by third round technical knockout (TKO).

KSI V Logan Paul I

Main article: KSI V Logan Paul

Following his victory against Joe Weller, KSI called out both Logan and Jake Paul as his next opponents. After many disagreements and much uncertainty about whether the fight would happen and who KSI's opponent would be, the fight between KSI and Logan was officially announced on 18 March 2018. There were two press conferences for the fight; the first was in the US on the 16 June 2019 and the second was in London on the 18 July 2018.

On 25 August 2018, KSI and Logan Paul contested in an amateur boxing event at the Manchester Arena in Manchester, England. After six rounds, the fight resulted in a majority draw with two judges scoring it 57-57 and one judge scoring it 58-57 in favour of KSI.

KSI V Logan Paul II

Main article: KSI V Logan Paul (2019)

As a result of the first fight being a draw, both KSI and Logan Paul agreed on a rematch. On 3 September 2019, the rematch was officially confirmed, along with the announcement that it would be a professional fight with no headguards, and that it would be promoted by Eddie Hearn. KSI officially registered as a pro boxer with a professional boxing license; he trained for the fight under his coach, Viddal, and Jeff Mayweather.

On 9 November 2019, the professional bout took place at the Staples Centre in Los Angeles, California. After six rounds, KSI was announced as the winner by split decision with two judges scoring 57-54 and 56-55 in favour of KSI, and a third scoring it 56-55 if favour of Logan.

KSI and Logan shared an embrace in the ring, and payed respects to one another. Logan announced that he had appealed the decision of the fight, however the appeal was denied in December 2019, assuring that KSI had won the fight.

Events - 2017

Disillusionment with Fame

KSI did not upload any videos to any of his YouTube channels from February to June 2017. He also "blacked out" all profile pictures and banners across all of his YouTube and social media accounts. He additionally took down videos worth a combined two billion views and deleted all of his Instagram posts except for one. This began to worry many of his fans, with some thinking he was suffering from depression or some other illness.

KSI followed this up with a series of since-deleted tweets where he explained that he had come to dislike his "fame" and the special privileges he knows he gets on the grounds of being a "celebrity" and stated that he would no longer like to be called a celebrity and wants to become a more "normal person". He also tweeted a quote by Charles Darwin that says: "We stopped looking for monsters under our bed when we realized that they were inside us."

In an interview with DramaAlert, KSI said he did all of this so he could "evaluate himself as a person" and stated that he that he "doesn't care about the fame or money" and that he wants to "cleanse himself" as a human. KSI had been completely inactive on all his social media until he uploaded a photo on Instagram on 6 May 2017 saying "Growth".

He was, however, occasionally seen in the other Sidemen videos, such as those uploaded by Miniminter and Behzinga. He also took part in the sidemen 2017 charity football match.

After his return, in Josh's Homegrown Podcast, JJ stated that he was tired of all the controversy and restrictions that come with the life of a YouTuber. JJ said he didn't like the state of the website and how people no longer made videos for fun. He travelled around the world when he was off the internet and claimed that he was "trying to evolve". Eventually, he explained how he no longer wanted to feel so "trapped" and would focus more on the reason he wanted to do YouTube in the first place, which was to enjoy making content.

Space EP

Main article: Space (EP)

On 23 June 2017, KSI posted a new video, entitled "It's been a while...", implying that his return to YouTube is imminent. Alongside posting that video, he also tweeted out about an upcoming EP, called Space. It was released on 30 June 2017.

Four days later (27 June 2017), KSI posted another video, his music video for the song Creature. It's the only song that has been released from the Space EP so far. It was previewed in the "It's been a while..." video, as the song appears to be heard in the background of the video.

The description of the video states "for Alfie". Alfie was a fan of KSI and Deji who was living with bone cancer. KSI and his brother visited Alfie prior to the release of the song (and gave him a shirt). It is very much thought that the video is dedicated to him.

Sidemen War

Leaving the Sidemen

On 3 August 2017, KSI tweeted out that he was planning to leave the Sidemen. He followed this up with a YouTube video citing Ethan as his main reason for quitting. After having the blame put on him, Behzinga decided to release a disstrack against KSI named "Drama". The song was uploaded on 7 August. Out of nowhere, on 8 August, W2S released his own track against KSI named "KSI Sucks".

After a week, on 12 August, KSI finally released (with RiceGum) his own diss track against Behzinga called "Earthquake". On 13 August, KSI released his second diss track on W2S named "Little Boy". The drama quickly escalated until Behzinga released - on 18 August - his second diss track on KSI; responding to "Earthquake".

A few days later, W2S released his own second diss track called "KSI Exposed". KSI released another diss named "Two Birds One Stone", targeting both W2S and Joe Weller. It was the last diss track KSI made against members of the Sidemen.


On 20 August, NetNobody released his own diss track against KSI named "'Diss Track ED". Eventually KSI got in contact with NetNobody's ex-girlfriend who had used NetNobody and treated him horribly, making a collaborative diss track against NetNobody named "Adam's Apple". NetNobody released his own diss track against the two named "Bend the Knee". At the end of the video, NetNobody reveals that he entered the drama only so he could get his son back, because his ex doesn't let him visit the child for various of reasons.

Review of Disstracktions

At the end of "Adam's Apple", KSI revealed that he'd be compiling the disstracks into an EP called "Disstracktions". The EP was released in September 2017.

Release of Transforming

On 15 September 2017, KSI released his new song "Transforming". In the song, KSI raps about everyone not understanding him and not letting him be himself.

Events - 2018

Release of Uncontrollable

On 31 January 2018, KSI released his new song ''Uncontrollable''. As the title says, KSI raps that no one can control him. It was basically a teaser of the boxing match against Joe Weller. The song was used for his ringwalk on the day of the boxing match.

Events - 2019

Return To Second Channel

After over a year of not posting videos on his second channel, he posted an announcement vid on December 31 of 2018, announcing that he would return to posting regular content on his second channel.

Beef with MaximillianMus

Maximillianmus and he had a small beef in late January 2019, at the time Max released a song called "Oh Yeah Yeah" which throughout the song, repeated the phrase "Oh yeah yeah" a lot of times. The song went viral and hundreds of videos comment sections were being raided by people spamming "Oh yeah yeah" on them, one of the channels being KSI. KSI tried to stop this, since he thought it was ruining YouTube, by starting "Operation Blackout" where you would blackout your profile picture, and just spam "STOP" on all YouTube comment sections being raided by "Oh yeah yeah" comments. When he was doing a One Question Go video, Max managed to get in the server in time, and confronted KSI about Operation Blackout. The operation was a failure, so KSI surrendered and changed his profile pic to Max's except with a bandana temporarily, which fixed his comment section, and after a couple months the meme died down. It is assumed that the 'beef' was somewhat of a joke and that there is no actual drama between KSI and Max.


New Age Album

Main article: New Age

In 2019, he and Randolph begun working on an album together titled "New Age" that would have 10 songs on it, 3 of them being singles. The album was released on April 12, 2019 and reached Number 17 in the UK Albums Chart.

New Age Tour

Throughout May and July, he and Randolph went on tour to promote the New Age Album. They performed most of the songs from the New Age Album, but also played a lot of other songs from KSI's other albums like the Space EP, and Disstracktions too.

Boxing Match

It was revealed on September 3 that the KSI v Logan Paul rematch was taking place on November 9 in the LA Staples Centre. The fight, unlike last time, is a professional boxing match with no head guards.

The fight resulted in a win by split decision for KSI.

Press Conference

The press conference for the rematch took place on September 14 in the Gilbert Lindsey Plaza, LA.

A music video for the song was filmed on November 11th in Los Angeles and premiered on KSI's YouTube channel on November 22nd.

The song entered the UK Singles Chart at number 17 and peaked all the way up to number 10, becoming KSI's highest-charting single in the UK until it was surpassed by Houdini in April 2020, outperforming his previous highest-charting song, Lamborghini, which managed number 30.
