In the years since, he has fought six more opponents -- Creator/LoganPaul (who he fought twice[[note]]The first time was on 25 August 2018 in the Manchester Arena as an amateur fight, with Logan and KSI coming to a controversial majority draw.

His current professsional record[[note]]meaning that the Weller match (which KSI won as a TKO) and the first Logan Paul match (which was a majority draw in KSI's favour) don't count[[/note]] is 4-1-0-1, consisting of one split decision victory, three KO victories, a "no decision"[[note]]In his fight with Joe Fournier.

The fight originally ended in a loss for KSI by ''majority'' decision, but this was changed a day later due to one of the judges having incorrectly counted their points[[/note]].

As far as music goes, KSI's career began early in his [=YouTube=] days with a series of comedic ''FIFA''-based songs made with his rapper-producer friend Randolph before doing guest verses on several songs by British rapper Sway. He released [=EPs=] between 2016 and 2017, and transitioned to full-length albums around the end of the 2010s, one of them a fully collaborative work with Randolph (''New Age''). As his discography has progressed, he has gotten more serious with his craft, expanding his hip-hop sound to work with influences from R&B, pop, and dance music, racking up collaborations with established UK and US artists, and [[GrowingTheBeard seeing a considerable increase in public support of him as a legitimate artist]] as opposed to making "[=YouTuber=] music".

** In one of his Q&As, he actually says that wanking every day is the reason why he's so funny.
** He mentions one time where he masturbated ''during Spanish class''. He wasn't noticed by the teacher, but was noticed by some classmates.
** In his Pink Slips video against Fangs, [[ItMakesSenseInContext he wears a horse mask while masturbating to horse porn.]]

KSI also released an autobiography in 2015 titled ''I Am a Bellend'' (or ''I Am a Tool'' [[MarketBasedTitle in the United States]]), co-starred in the 2016 direct-to-video comedy film ''Laid in America'' alongside [=YouTube=] star [[https://www.youtube.com/user/dicasp Caspar Lee]], served as the focus of a 2019 documentary titled ''KSI: Can't Lose'' ahead of his rematch with Logan and an upcoming 2023 documentary titled ''KSI: In Real Life'' centering around his life from June 2021 to October 2022, and announced co-ownership of a hydration brand called Prime in 2022 alongside Logan, following the two squashing their beef and becoming friends.

While KSI predominantly uploaded videos to his main channel for a long while, using [[https://www.youtube.com/user/KSIOlajidebtHD his second channel]] "JJ Olatunji"[[note]]initially ''VideoGame/CallOfDuty''-only, and formerly named "[=KSIOlajidebtHD=]" before [=YouTube=] verification issues inspired the change[[/note]] to post content from a broader palette of games (often played with the Sidemen), his pursuit of a music career turned the main KSI channel into a professional hub of official music videos, singles and miscellaneous high-production-value content. His second channel, now updated far more frequently, currently hosts more fun and informal content; think of it as JJ the regular person, as opposed to KSI the big-name superstar. Recurring content includes ''Try Not to Laugh'' (where he reacts and [[RunningGag almost always fails]] to avoid laughing at funny videos), ''Well...That Was Weird'' (where he reacts to simply [[SurrealHumor bizarre]] videos), and a regular series of him reacting to fanmade content on his [[Website/{{Reddit}} subreddit]] (available [[https://www.reddit.com/r/ksi here]]). In March 2021, he (alongside many other Sidemen) also started [[https://www.youtube.com/channel/UCMiY4t431lhXY4QtPZtzftQ another channel]] dedicated to short highlights of videos he's been in.

Another prominent career path KSI has taken is into the world of [=YouTube=] boxing.

He subsequently called out and challenged Creator/{{Jake|Paul}} and Creator/LoganPaul, who agreed to respectively fight KSI and his younger brother WebVideo/{{Deji}}, also a prominent [=YouTuber=], later that month. The highly-anticipated event occurred on 25 August 2018 in the Manchester Arena, with Logan and KSI coming to a controversial majority draw. A rematch, which was already planned alongside the first match, was held on 9 November 2019 at the Staples Center. This fight was distinctly held as a ''professional'' boxing match, with no headgear and lighter gloves, and ended in a split decision in favour of KSI. He then went on hiatus from boxing to focus on his music and content, eventually announcing that he would return to the ring on 27 August 2022. He fought two opponents that night -- rapper Swarmz and pro boxer Luis Alcaraz Pineda[[note]]The fight was originally planned to be against [=YouTuber=] [[https://www.youtube.com/c/Wassabi Alex Wassabi]], but he withdrew from the fight due to a concussion and was replaced with Swarmz on 6 August.

He will fight next on 14 January 2023 against mixed martial artist Dillon Danis.

** Note that "Scary" comes from the {{running gag}}s of [[BlackComedyRape rape-based humour]] with his rape face, "angry" comes from his excessive hamminess and quick tendency to get irked.

Another prominent career path KSI has taken is into the world of [=YouTube=] boxing. On 3 February 2018, he settled a months-long beef with fellow British [=YouTuber=] [[https://www.youtube.com/c/JoeWeller Joe Weller]] in the ring at Copper Box Arena, ultimately scoring a TKO victory in what was one of the most-watched white-collar matches in boxing history. He subsequently called out and challenged Creator/{{Jake|Paul}} and Creator/LoganPaul, who agreed to respectively fight KSI and his younger brother WebVideo/{{Deji}}, also a prominent [=YouTuber=], later that month. The highly-anticipated event occurred on 25 August 2018 in the Manchester Arena, with Logan and KSI coming to a controversial majority draw. A rematch, which was already planned alongside the first match, was held on 9 November 2019 at the Staples Center. This fight was distinctly held as a ''professional'' boxing match, with no headgear and lighter gloves, and ended in a split decision in favour of KSI. He then went on hiatus from boxing to focus on his music and content, eventually announcing that he would return to the ring on 27 August 2022. He will be fighting two opponents that night -- rapper Swarmz and pro boxer Luis Alcaraz Pineda.[[note]]The fight was originally planned to be against [=YouTuber=] [[https://www.youtube.com/c/Wassabi Alex Wassabi]], but he withdrew from the fight due to a concussion and was replaced with Swarmz on 6 August.

His second channel, now updated far more frequently, currently hosts more fun and informal content; think of it as JJ the regular person, as opposed to KSI the big-name superstar. Recurring content includes ''Try Not to Laugh'' (where he reacts and [[RunningGag almost always fails]] to avoid laughing at funny videos), ''Well...That Was Weird'' (where he reacts to simply [[SurrealHumor bizarre]] videos), and a regular series of him reacting to fanmade content on his [[Website/{{Reddit}} subreddit]] (available [[https://www.reddit.com/r/ksi here]]).

In March 2021, he (alongside many other Sidemen) also started [[https://www.youtube.com/channel/UCMiY4t431lhXY4QtPZtzftQ another channel]] dedicated to short highlights of videos he's been in.

** In one of his Q&As, he actually says that wanking every day is the reason why he's so funny.
** He mentions one time where he masturbated ''during Spanish class''. He wasn't noticed by the teacher, but was noticed by some classmates.
** In his Pink Slips video against Fangs, [[ItMakesSenseInContext he wears a horse mask while masturbating to horse porn.]]
** Implied in his verse on "No Sleep":

Even when I was eleven\\
Heaven was finding the seven\\
Minutes alone in my bedroom\\
