Nov 9 (Reuters) - China-based Sogou Inc's shares rose more than 10 percent in their U.S. market debut, as investors expect a massive base of Chinese smartphone users to help the Tencent-backed search engine company narrow the gap with market leader Baidu.
Shares of Sogou rose as much as 13.1 percent on the New York Stock Exchange on Thursday morning, valuing the Beijing-based firm at $5.76 billion.
Sogou's initial public offering was priced at $13 per American depository share, at the high end of the expected $11 to $13 range, and raised $585 million.
Its IPO follows Wednesday's hugely successful Hong Kong IPO of China Literature Ltd, the e-book unit of Chinese internet and media giant Tencent Holdings Ltd.
It also represents the latest in a recent flurry of New York listings by Asian companies, joining other Chinese firms as well as startups from Singapore and Taiwan in tapping U.S. equity markets for capital this year.
Founded in 2005 by internet firm Sohu.com Inc, Sogou runs China's second largest search engine by mobile queries, rivaling Baidu Inc, and Alibaba's UCWeb. It generates revenue mainly through search advertising services.
Google, the world's most popular search engine, is largely blocked in China.
Sogou expects the size of the domestic online search industry will balloon to $30.7 billion in 2021 from $11.5 billion in 2016, driven by the hundreds of millions of Chinese who browse the internet on their mobile phones. Sogou says this massive user base represents a largely untapped opportunity to make money through ads.
Sogou, the default search service on Tencent's Mobile QQ browser and qq.com, has about 483 million mobile monthly active users, according to its IPO paperwork bit.ly/2jdluwP with U.S. securities regulators.
Baidu, in contrast, had some 665 million monthly active mobile search users in December 2016, the last period for which it disclosed the metric.
Sogou's net income climbed 47 percent to $66.7 million in the nine months ended Sept. 30. Its revenue jumped 29 percent to $630.6 million in that period.
Sohu will remain Sogou's controlling shareholder after the IPO, while Tencent will own a 38.7 percent stake.
Tencent's other notable investments include stakes in ride service Lyft, electric car maker Tesla Inc and most recently a substantial investment Snapchat owner Snap Inc .
