Paddy Power refunded all the bets that came in, and chastised Trump.
"Donald Trump had us all on the edge of our seat anticipating a game changing announcement and we get this!?" Paddy Power spokesperson Féilim Mac An Iomaire said in a statement. "We imagine that those who bet on the announcement feel as cheated as we do and that the only fair thing to do is to refund them their stakes."
Even before the announcement was revealed to be a promise by Trump to donate $5 million to charity in return for Obama's college records, anticipation of Trump's big news didn't prove very attractive to gamblers. Paddy Power reported that "just over $500" in wagers had been placed before Trump's announcement was made.
