Almost certainly not. “Famous” is a strong word. A lot of fortune 500 companies are holding companies, many of them not even holding household name brands but business-to-business providers that nobody outside the business world or industry they’re involved in have ever heard of. I work for one (more specifically, I work for a massive technology company that is owned by one of them), the parent company is on the Fortune 500, I can pretty much guarantee you’ve never heard of them. I hadn’t until one of their subsidiaries purchased the company I was working for. Many of them are just holding companies that own brands you have heard of, but you’ve probably never heard of the company that owns them. It changes more often than you’d think, sometimes they change names and owners so frequently you might suspect they’re specifically trying to avoid the attention of becoming “famous”.

You can, of course, look them up on the list. But they’re just a name, and a description, and a breathless history of how they started and how innovative and clever they are, and a vague collection of noteworthy brands and assets, but it’s all ephemeral and disposable. They have nothing to be famous for. They have no history they care about. The only thing that puts them on the list is how much they own, and how much new stuff they buy to make sure they keep their share of the market and prevent anyone from challenging them. They don’t do anything besides owning.
