no one seems to be able to confirm that Elon's Floki Inu is a business mogul, and it also looks like Elon Musk hasn't made an official announcement about it yet. But I think one way or another, he was somehow involved in the development of the project.
Rich people are always easy to get involved in any business, including those kinds of projects, because Elon Musk is a person who wants to work hard on all businesses and on all projects that can make him lucky, so don't be surprised if Elon Musk is also in the Floki Inu project.
