Saudi Aramco, the world’s biggest oil company, ended trading on Monday with a market value of over $2 trillion, a worth that had eluded it when it took its shares public.

Shares in the company closed at 38 riyals, or about $10.13, giving the company a valuation of $2.03 trillion on the Saudi exchange.

The company made its market debut on Wednesday at a value of $1.88 trillion. Resistance from global investors and Western advisers forced the company’s leadership to settle for a valuation below the target of $2 trillion set by the kingdom’s chief policymaker, Crown Prince Mohammed bin Salman. But in four trading days, strong demand, mostly from Saudi retail and corporate investors, pushed the shares above the prince’s goal.

Aramco, whose roots date back to the discovery of oil in Saudi Arabia in the 1930s by American prospectors, is a rare case of an old-line company that tops technology giants in market value. With a near monopoly on production in the world’s leading oil-exporting nation, Aramco is worth far more than Apple or Microsoft, each valued at about $1.2 trillion. It also far outstrips the combined worth of five of the largest Western companies, Exxon Mobil, Chevron, Total, BP and Royal Dutch Shell.
