Australia’s biggest sports betting operator Tabcorp Holdings Ltd. is resisting the pressure to rush into the U.S. betting market, preferring to complete the company’s integration with Tatts Group first before expanding its business.

The Australian Financial Review reported that Tabcorp is closely monitoring regulatory developments in the United States, but noted that the company is in no hurry to carve out a slice of the country’s sports betting pie.

Speaking before the members of American Chamber of Commerce in Australia on Wednesday, Tabcorp CEO David Attenborough recognized that the U.S. sports betting market is still filled with uncertainty despite the repeal of the Professional and Amateur Sports Protection Act (PASPA) of 1992.

He pointed out that sports betting regulations are a patchwork, making it hard to predict on how quickly the U.S. market will open up.
