Kai is currently sitting at 2.2 million followers on Twitch (with 90,000 subscribers) and 2.3 million subscribers on YouTube. This all didn't happen for no reason; one step at a time, he built his fanbase with patience and precision. He picked the perfect platforms to debut his content: YouTube and Twitch are a perfect fit for him (as well as the short-form bits that land on other platforms like Instagram and TikTok). He's also built a substantial standing on Twitter, with over 700,000 followers. It's pretty clear at this point that he can outperform virtually anyone via any form social media.
In addition to his own impressive social media stats, he's collaborated with SideTalk, showing off just how much of a New Yorker he is, as well as how entertaining he is. Almost exactly a year ago, together they dropped a video of Kai going around the Feast of San Gennaro in Little Italy. He runs into Lil Uzi Vert, and that's just the tip of the iceberg.
