Saudi Aramco was the world’s most valuable publicly traded company at the end of its 2019 IPO.
When Saudi Aramco completed its listing in December 2019, its share price and number of outstanding shares implied a market capitalization of approximately $1.9 trillion. That valuation made it the largest publicly traded company at the time, surpassing other major oil producers and global technology firms.
The listing followed years of preparation by Saudi Arabia. The government sold a minority stake while retaining overwhelming ownership, allowing the company to access public markets without giving up control. The IPO was part of broader efforts to diversify the Saudi economy and raise capital for the country’s development plans.
Aramco’s market value was closely tied to oil prices, production expectations, reserves, and investor views about the future of energy. A company’s ranking can therefore change even when its share count remains largely unchanged.
