Crown Prince of Saudi Arabia Mohammed bin Salman Al Saud (C) visits Innovation and Technology fair at Massachusetts Institute of Technology in Boston, Massachusetts, March 25, 2018.

Saudi Arabia's king in waiting says the stock market debut for the kingdom's oil giant Aramco will go forward by early 2021.

Crown Prince Mohammed bin Salman gave the update for the initial public offering in an interview with Bloomberg one month after Reuters reported that Saudi Arabia had scrapped plans to list shares in the company. Saudi Arabia Energy Minister Khalid al-Falih disputed that report, saying the kingdom would take Aramco public when the time is right.

That time now appears to be roughly two years from now, according to the crown prince, who is often referred to as MBS. The royal also reiterated his view that Aramco is worth $2 trillion, though analysts have said a $1 trillion to $1.5 trillion valuation is more likely.

"I believe late 2020, early 2021," MBS told Bloomberg. "The investor will decide the price on the day. I believe it will be above $2 trillion. Because it will be huge."

The kingdom was originally targeting 2018 for the IPO, but Falih said earlier this year 2019 looked more likely.

Saudi Aramco CEO Amin Nasser told CNBC last month that the IPO would be delayed indefinitely by the company's bid to purchase a majority stake in petrochemicals company Saudi Basic Industries Corporation, or SABIC.

Despite the delay, Nasser said the government remained committed to taking a portion of Aramco public.
