PetroChina became the first company to reach a $1 trillion market capitalization in 2007.
PetroChina briefly reached a market value of approximately $1 trillion on its Shanghai listing in November 2007. The milestone came during a period of strong investor enthusiasm for Chinese equities and high global oil prices.
PetroChina is the publicly listed arm of China National Petroleum Corporation, one of China’s major state-owned energy groups. Its activities include oil and gas exploration, production, refining, transport, and sales.
This historical milestone is often overlooked because later trillion-dollar records were dominated by U.S. technology companies. PetroChina’s valuation soon fell from its peak, illustrating that market-cap records can be temporary and strongly affected by market conditions.
