The Saudi government and its wealthiest citizens helped lift Aramco to Saudi Crown Prince Mohammed bin Salman’s coveted valuation target of $2 trillion—if only for a few hours.

Aramco’s share price on Saudi Arabia’s Tadawul exchange jumped nearly 10% to 38.7 Saudi riyals ($10.32), briefly valuing the oil giant at $2 trillion Thursday. The shares ended the day’s trading at 36.8 riyals and a valuation of $1.96 trillion. That was up from $1.7 trillion set during the company’s initial public offering, the world’s largest ever.

Still, Prince Mohammed and his officials can point to the milestone as proof that Aramco, known officially as Saudi Arabian Oil Co., was worth $2 trillion.

A number of wealthy Saudi families, some of whom had relatives caught up in the Crown Prince’s 2017 anticorruption crackdown, as well as government funds, were asked to buy shares in the company to support a $2 trillion valuation after it was listed on the domestic exchange, according to senior Saudi advisers familiar with the IPO planning.

Some of the families were approached by Aramco executives who told them it was their patriotic duty to invest in the kingdom’s national oil company. Others were approached by advisers from the royal court.
