Las Vegas casino operator Wynn Resorts plans to raise up to $1 billion by listing its Macau assets on the Hong Kong stock exchange, two sources with direct knowledge of the deal said on Friday.

The listed unit, Wynn Macau Ltd, will sell 20 percent of its enlarged share capital, said a source who declined to be identified. The tentative listing date for the IPO is set for Oct 9, the source added.

Hong Kong's stock regulator on Thursday approved Wynn's application to launch its initial public offering in Hong Kong, according to a second source.

JP Morgan, UBS AG and Morgan Stanley have been designated to handle Wynn's Hong Kong listing.
