ND's payout from NBC has never been confirmed, but is widely reported to be $15M / yr. From what I can gather, here are the most recent payouts / team from the respective conferences. Yes, I track this stuff. No, I have no life.....
B10 - $51M
SEC - $45M
B12 - $38M
ACC - $32M
P12 - Unknown, but reported to be 'more than the ACC'.
ND also gets money from the ACC for football, which is not a full share, reportedly $6 - $10M per year. When the new SEC deal kicks in, in 2 (or 3?) years, the SEC will leapfrog the B10.
I maintain the best path forward for ND is to create and monetize its own network.
The myth that Notre Dame is independent for money is just that, a myth.
