Days before Saudi Arabia launches its flagship investment conference, a select group of guests will get their first look at a $1 trillion project that Crown Prince Mohammed bin Salman has bet the kingdom has a future beyond oil.

An exclusive group of financiers, artists and influencers will descend from around the world this week on Sindalah Island, the first project to open in the planned city of Neom, Bloomberg reported in a report seen by Al Arabiya Business. The resort now features luxury hotels and pristine beaches, as well as an 86-berth marina where the wealthy can moor their yachts and dive in the clear waters of the Red Sea.

Much depends on the success of Sindalah and the wider region in the northwest of the kingdom, which has been renamed Neom. It is expected to cost between $500 billion and $1.5 trillion to build, and is the kingdom’s boldest development move.

The opening comes days before the eighth edition of the Future Investment Initiative, which is expected to attract top executives from Wall Street and Silicon Valley.
