HONG KONG — A battle for supremacy in Macao’s gambling market is shaping up between the casino tycoon Stanley Ho and an American newcomer as the Chinese enclave emerges as the biggest gambling territory in the world.

Gambling revenue from casinos in Macao leapt 46.6 percent last year to reach about 83 billion patacas ($10.4 billion), according to industry analysts and officials.

With roaring growth expected to continue this year, Macao is poised to overtake all of Nevada as the biggest gambling jurisdiction, after it surpassed the Las Vegas Strip last year.
