China's streaming site Douyu said it "is not aware" of the reported plan of an IPO in the US to raise $600 million to $700 million, industry website 36kr.com reported on Monday.

The Financial Times quoted industry insiders as saying that the Tencent-backed 5-year-old start-up is "weighing up a US debut" to capitalize on China's booming e-sports market.

Douyu's rival Huya raised $180 million with an IPO in the US in May, news website investor.com reported. The gaming company's shares are now traded at about $36, almost three times from its IPO issue price of $12.
