Summary:
"We have chosen to pay out on Biden early while allowing Trump bets to remain unsettled until there is more clarity."
We're actively settling Biden bets now as a win, if you bet on him you will get paid within 24h.
Great way to handle it.
Lots of books aren't settling till Jan (or even Feb). Paying out without settling losing tickets is not something most would even consider. Hopefully you don't have to pay the losers.
