HONG KONG (Reuters) -China's Unitree Robotics is looking at as much as 50 billion yuan ($7 billion) in company valuation for its planned initial public offering, two people with knowledge of the startup's plans said.

Unitree said last week on its X account that it was actively advancing the IPO preparations and was expecting to submit the listing application documents in the fourth quarter of the year.

It did not provide other details including a timeline for a potential listing.

If successful, Unitree's IPO would be one of the biggest and highest profile onshore tech listings in years, and would come as Beijing steps up efforts to support its tech champions in tapping capital markets for their funding needs.

Chinese exchanges are experiencing a gradual revival in IPOs after nearly a two-year hiatus due to tightened regulatory scrutiny of applications and a volatile stock market.

Onshore IPO proceeds totalled $7 billion so far this year, up 40% year-on-year but still a far cry from the tens of billions raised from 2020 to 2023 for the same period, LSEG data showed.

A resurgent Chinese IPO market could help fund Beijing's technology self-sufficiency drive and keep the country's "unicorns" - firms with valuations of over $1 billion - in onshore markets, while aiding an economy suffering from the Sino-U.S. trade and tech wars.

While it is not immediately known how much Unitree is seeking to raise in the IPO, a company with a valuation of around 50 billion yuan typically has to issue more than 10% of its shares in an IPO in China.

Hangzhou-based Unitree did not respond to Reuters requests for comment.

Unitree, which has more than 30 investors according to local corporate registry disclosures, plans to list on Shanghai's technology-focused STAR Market, said the sources. They declined to be named as they were not authorised to speak to the media.

In a funding round in June, Unitree won new investors including tech giants Alibaba, Tencent and automaker Geely Holding Group, local media reported at the time.

Geely, which confirmed it was an investor, declined to comment on Unitree's IPO plans. Alibaba and Tencent did not immediately respond to Reuters requests for comment.

UNICORN STATUS

Unitree's IPO will test investor interest in humanoid robots, a frontier industry that China is well positioned to lead, thanks in part to its diverse and largely self-sufficient manufacturing supply chains.

The industry has benefited from an abundance of local government subsidies and favourable policies.

Unitree's targeted IPO valuation of as much as 50 billion yuan, if achieved, would be a sharp jump from its 12 billion yuan value in the last fundraising round in July, said one of the sources, adding the company is already profitable.

Sources also point out that Unitree - which has a coveted 'unicorn status - is an industry leader with big growth potential and it would be listing in a market that is known for offering high trading multiples.

Founded in 2016, Unitree leads the industry in terms of both production and sales, becoming a go-to choice for Chinese universities researching robotics, as well as a common sight in entertainment and sporting events all over China.

Its founder Wang Xingxing said after the June fundraising that Unitree's annual revenue had already surpassed 1 billion yuan.

In February, Wang was among business leaders in China's private sector that attended a rare meeting with President Xi Jinping.

Unitree began its so-called IPO tutoring process in July, with CITIC Securities acting as its tutoring institution in preparation for the listing.
