doctor strange 2 revealed that the illuminati are a thing in the multiverse but they may be around on the main mcu earth as well spoilers ahead for multiverse of madness so all the way back in iron man 2 there is a folder that can be very briefly seen on tony stark's phone labeled illuminati it was never brought up again since the mcu was focused on telling different stories but iron man is a key member of the illuminati in the comics alongside doctor strange professor x mr fantastic and black bolt all of whom appeared in multiverse
madness so is it too crazy of an idea that stark was putting a secret team together in the background as the phases went by or maybe he was just collecting ideas and thoughts that could be passed on to someone like doctor strange or roadie like he did with the edith glasses and peter parker which could lead to the formation of the team in the main earth 616 sometime in the future
