It is the first new resort to be completed on the Las Vegas Strip since the Cosmopolitan opened in 2010. At a cost of $4.3 billion, Resorts World is the most expensive resort property ever developed in Las Vegas.

Resorts World Las Vegas, which opened its doors in mid-2021 and remains one of the most technologically advanced properties on the Strip in 2026, carried a staggering construction price tag of $4.3 billion. This makes it the most expensive resort ever built in Las Vegas, surpassing the $3.9 billion cost of the Cosmopolitan. Developed by the Genting Group, the massive budget was utilized to integrate three distinct Hilton-branded hotels (Las Vegas Hilton, Conrad Las Vegas, and LXR Hotels & Resorts) into a single 3,500-room complex. The cost also covered a 117,000-square-foot casino, a 5,000-seat theater, and a 100,000-square-foot LED screen on the West Tower, which is one of the largest in the world. In 2026, the resort continues to justify its massive investment through high-tech features like "cashless" gaming and an underground station for Elon Musk’s Vegas Loop. The $4.3 billion investment reflects a shift in Vegas development toward "integrated resorts" that prioritize luxury retail, world-class dining, and digital immersion over traditional slot-machine-heavy layouts.
