Good read,

explains the numbers behind what Conor could potentially make
"So if they cut it $10 and offer it at $79.95, that means that at 4 million sales, they’ll generate nearly $320 million, or $136 million going to the promotion.
If Mayweather-McGregor has the same 60-40 split that Mayweather-Pacquiao had, that would mean $81.5 million would go to Mayweather and $54.4 million would go to be split between McGregor and White."
So best case he splits 54.4 with uncle Dana and co.
With the way the UFC likes taking the Lions share I doubt he even makes 25 mil.
