At a cost of $4.3 billion, Resorts World is the most expensive resort property ever developed in Las Vegas. It is the first new resort to be completed on the Las Vegas Strip since the Cosmopolitan opened in 2010. Wynn had accused Genting of misleading its visitors into believing that Resorts World was affiliated with the Wynn properties. Further design changes were made after Wynn Resorts filed a lawsuit against Genting, alleging that Resorts World was too similar to the nearby Wynn/ Encore properties. Groundbreaking took place in May 2015, and construction began in late 2017. However, the opening date was delayed several times due to redesigns of the project. Groundbreaking was initially scheduled for 2014, with the first phase expected to open in 2016.

The project re-used some of the partially finished Echelon buildings, including hotel and parking garage structures. Genting immediately announced plans to redevelop the site as Resorts World Las Vegas, part of its Resorts World brand. Boyd halted construction in 2008 due to poor economic conditions and sold the property to Genting in March 2013. The property is owned and operated by Genting Group and had been the site of the Stardust Resort and Casino until 2007, when Boyd Gaming demolished the resort to develop its Echelon Place project. Resorts World Las Vegas is a resort, mall, and casino on the Las Vegas Strip in Winchester, Nevada, United States.
