PetroChina was the first publicly traded company in Asia to reach a $1 trillion market capitalization. Its shares surged on the Shanghai Stock Exchange debut of its domestically listed A shares in November 2007.
PetroChina is the listed arm of China National Petroleum Corporation and operates across exploration, production, refining, chemicals, and fuel distribution. The company’s enormous scale and the strong Chinese stock market helped produce a valuation briefly associated with the trillion-dollar threshold.
The record was short-lived. PetroChina’s share price later fell, and market capitalization is inherently subject to changing investor sentiment. A company can therefore set a valuation record without maintaining that rank for long.
This milestone is sometimes confused with the later global records set by Apple and other U.S. technology companies. The wording “in Asia” identifies the regional first, while “publicly traded” distinguishes a stock-market valuation from estimates of private-company worth.
