The team, universally known as Evergrande, won its second AFC Champions League title in just three years on Saturday.
But the club, which is 40 percent owned by Chinese e-commerce giant Alibaba and the rest by property developer Evergrande, lost $75 million last year.
It will raise up to 2.65 billion yuan ($414 million) by issuing up to 66.2 million shares on China's little-known National Equities Exchange and Quotations (NEEQ) market, it said in a statement.
When it listed on the exchange earlier this month the 375 million shares in issue at 40 yuan each gave it a notional market capitalisation of a jaw-dropping $2.35 billion -- putting it in a similar league to New York Stock Exchange-listed Premier League club Manchester United, which is worth $3 billion.
Little-known Shenzhen Grandland Decoration Group said late Thursday it would buy 3.75 million shares in the fund-raising, giving it just under one percent of the club.
It was the first new investor to identify itself, and said in a statement to the Shenzhen stock exchange that becoming a shareholder in the club would "increase its domestic and international reputation".
In China, football clubs often serve their tycoon-owners by providing political capital, a show of hometown loyalty or a trophy in a business empire.
