These are the 20 largest oil companies in the world. Is Pertamina among them?

JAKARTA, KOMPAS.com - The Visual Capitalist website recently published the 20 largest oil companies in the world by market capitalisation. The number one and the largest is Saudi Aramco of the Kingdom of Saudi Arabia with a market capitalisation of US$1.8 trillion (approximately IDR 31.8 quadrillion).

“This state-owned giant of Saudi Arabia is worth more than the combined market capitalisations of the next five largest publicly listed oil and gas companies, including ExxonMobil, Chevron, Shell, and PetroChina,” VisualCapitalist.com said, quoted on Friday, 22 May 2026.

Here is the list of the 20 oil companies with the largest market capitalisations in the world.

PT Pertamina (Persero), owned by the Indonesian government, is a non-listed company that is not on the Indonesia Stock Exchange (BEI).

As a result, its market capitalisation is not publicly known, but its valuation is projected to reach US$100 billion (IDR 1.71 quadrillion).
