"Once we get that going, it could be a monster," said Arum.
Even if Chinese pay per view doesn't take off, Macau will still remain a viable boxing venue because for non-American fighters it will represent a bigger purse. They won't have to pay U.S. taxes of about 40 percent on their earnings.
That would be a substantial incentive for someone such as Pacquiao, who would only be subject to lower tax rates in the Philippines or Macau on the $25-$30 million that Arum said he's expected to earn from the November fight.
The biggest upside from the fight nights, however, may be for the casino. It benefits directly from more visitors, which will help raise gambling revenue. The Pacquiao fight will be an especially good chance to reel in the high-rolling mainland Chinese VIP gamblers that have supercharged Macau's casino industry.
It also gives casinos another way to circumvent the advertising and promotional restrictions that come with mainland China's ban on casinos.
"The boxing in Macau without doubt helps promote Sands China or the Venetian brand in China," said Aaron Fischer, head of gaming research at brokerage CLSA Asia-Pacific Markets. "Marketing of casinos is illegal in China and hence gaming companies will have to indirectly promote the integrated resort by marketing the non-gaming facilities like the hotel, conventions or by marketing the various events like boxing matches."
