Is there any social media company that is profitable? Facebook is an advertising platform with a side-hustle as a social media site. Other than that, Twitter was losing money and since Elon is losing much more, Reddit is losing money, Discord is losing money, Snapchat is losing money.
YouTube is Google. Google and Facebook are advertising companies who have side hustles doing other things like showing videos. So far, nobody else has managed to do that. Is it possible another ad company with a social side-hustle could emerge? Sure, but Facebook and Google are going to do whatever they can to either buy up or destroy any company that got too successful at that.
Yeah, there are a few Chinese apps that may be profitable like Weibo, WeChat, TikTok, etc. But, it's hard to really know. Also, the ones that are China-based may not be profitable outside China. Like, apparently WeChat is more a platform than a social media app, and people use it for payments, gaming, and all kinds of other things. That might not translate to any other country.
