The figures - touted as high as a possible $180m payday for the unbeaten American and an estimated $120m bonanza for Pacquiao - intensified the spotlight on a fight between two of the most successful boxers of their generation.
Al Jazeera's Andy Gallacher, reporting from Las Vegas, before the match, said the atmosphere in the city was "electric" as hundreds of thousands of people had swarmed there just to be close to the fight.
"It's been building up and counting down and now the streets of Las Vegas are completely packed," he said.
In the Philippines, Al Jazeera's Jamela Alindogan, reporting from General Santos, said an "unofficial holiday" had been declared in the country of 100 million, with streets packed with Pacquiao's supporters waiting to watch the match on TV screens.
