News to me... He's not listed on any official promoters, agents, business affiliate database for boxing.
There is no record or qoute of him ever applying, studying, or ever having a boxing promoter license. No social media post. No legal contract. No media artcile.
No rumor even....
I'm sorry dude, but you are heavily misinformed...There is no trace of Conor ever owning a boxing promotion...
Example: Go ahead for yourself, click on promoter next to role in the biggest database :

Example of a boxing promoter license:
UFC is not a boxing promotion, that's why they don't have one, nor do I think they are going to.
Again, example of an MMA promoter's license :
Don't insult my intelligence, please.
