When it says 1pm, is it 1pm in UK or in US?
Anyway:
$1m on Lawrence Okolie, (1.5m if he wins)
then all winnings goes to Joshua Buasti (2.25m if he wins too)
then all winnings goes to Katie Taylor (3.375m if she wins too)
then all winnings goes to Joe Cordina (5.0625m if he wins too)
If anyone of them loses, I lose the $1m.
$50k on Astros (fave)
