AIA shares rose well above their initial public offering price of 19.68 Hong Kong dollars, after the company raised $17.8 billion in a share sale that remains on track to be the world's second-largest IPO this year.
The Asian insurer's offering may still top $20 billion if it exercises certain options.
"This is a new beginning for AIA," Mark Tucker, the company's chief executive, told reporters at a listing ceremony in Hong Kong on Friday.
"Our aim is to make sure we are the leading insurance company in Asia."
