Monthly GM challenge

From the past:

Prizes:
$500 if the grandmaster wins against REBEL.
$250 for a draw.
No prize money in case of a loss against REBEL.

How much money do we need today to get the same challange against Stockfish with 100 games against different GM's(humans always white) and do you expect 100 wins for stockfish as black or maybe humans can get a few draws?(I do not expect humans to win games)

In the hypothetical case, 20 years back in time but with the current Rebel I could think of:

GM - time control 40m in 2h
Rebel - 5m blitz, PB=off

$500 if the grandmaster wins against REBEL.
$250 for a draw.
No prize money in case of a loss against REBEL.

It's maybe an idea for Larry instead of knight handicaps.

Call it the "Take My Money Event, If You Can!"
