PetroChina was the first Chinese company to reach a $1 trillion market capitalization.
PetroChina briefly reached a valuation of about $1 trillion on November 5, 2007, during its first trading session in Shanghai. The company’s shares surged after its domestic listing, making it the first Chinese business to cross that symbolic market-value threshold.
PetroChina is the publicly listed oil and gas arm of China National Petroleum Corporation. Its activities include exploration, production, refining, transportation, and sales of petroleum products. The company’s market capitalization later declined as prices and investor expectations changed.
This record is distinct from the largest IPO record and from a company’s total enterprise value. PetroChina’s 2007 valuation also reflected a particular moment of strong enthusiasm in China’s stock market, so the brief peak should not be treated as a permanent ranking.
