Saudi officials claim preparatory work regarding the IPO has been completed but some key issues — such as where to list — rest with the government. Saudi Crown Prince Mohammed bin Salman is believed to favor listing Saudi Aramco in New York, while officials, including Energy Minister Khalid al-Falih, have reportedly said London could be a better fit. Hong Kong is also in contention. Another option is a Saudi listing alongside an international exchange. A domestic listing and a private sale to a strategic investor — possibly from Beijing — is a third possibility.
