Who is the richest private company?

Could you enlighten me on who currently holds the title of the richest private company in the world? I'm intrigued to know which organization, without the scrutiny of public markets, has managed to accumulate such immense wealth and value. Is it a tech giant that's revolutionizing industries with cutting-edge innovations, or perhaps a private equity firm with a diverse portfolio of successful investments? The question begs to be answered: Who reigns supreme among the privately held entities, boasting a financial standing that's nothing short of extraordinary?
