The sources said companies being considered for the shortcut could include Alibaba Group's (BABA.N) Ant Financial affiliate, the world's most valuable financial technology company; Zhong An Online Property and Casualty Insurance, and security software maker Qihoo 360 Technology Co.

Ant Financial, valued at $60 billion at its most recent funding round last year, is expected to be one of 2017's largest initial public offerings (IPOs). While Ant hasn't specified a preferred listing venue, analysts and bankers have previously said the deal will likely take place in Hong Kong, given the line in the mainland.

China has been losing out to the New York Stock Exchange (NYSE) and Nasdaq on key technology listings, so more IPOs at home could mean millions of yuan in revenue for Chinese investment banks, who dominate domestic stock issuance.

There are about 700 companies waiting for a green light from the China Securities Regulatory Commission (CSRC) to go public in Shanghai or Shenzhen.

Though the regulator has increased the pace of approvals in recent months, that still leaves a typical 18-month wait or longer before companies are able to raise funds, making the domestic market unattractive to fast-growing technology companies in need of funds to fuel their expansion.

In September the CSRC tweaked the rules to let companies in some impoverished Chinese regions skip the line, sharply reducing the vetting period for those issuers.

In January, companies in the Xinjiang Uyghur Autonomous Region that borders Russia and Mongolia were among those benefiting from faster approvals.

The sources said the CSRC had held talks with the technology companies for months, but no final decision had yet been reached on whether to allow the faster approval.

Ant Financial, Zhong An and Qihoo declined to comment.

The CSRC has yet to reply to a request for comment.

GOING WEST

Over recent years the United States has been a popular destination for listings by Chinese internet startups and software makers, given a larger pool of analysts familiar with the sector and fund managers used to investing in fast-growing companies who have yet to generate profits.

The $25 billion record IPO of e-commerce giant Alibaba in New York in 2014 was a high-profile loss for mainland China and Hong Kong, where the company initially intended to list.

More recently, however, some Chinese companies have opted to quit New York and relist back home, where valuations are several times higher than in international markets.

Qihoo took its New York shares private in a $9.3 billion deal last July and has said it wants to relist in China in due course.

By listing at home, Ant Financial, Zhong An and Qihoo would benefit from those high valuations, while also standing out because of their size compared with locally-listed peers. Domestic equity markets are dominated by massive state-owned enterprises (SOEs), including banks, real estate developers and conglomerates.

While there are almost 400 tech companies listed in Shenzhen and Shanghai, the vast majority are small firms, with an average valuation of $1.9 billion, dwarfed by the likes of Ant Financial.

The two largest-listed technology companies in China, video surveillance camera maker Hangzhou Hikvision Digital Technology (002415.SZ) and display maker BOE Technology Group (000725.SZ), have market values of $25.7 billion and $16.9 billion.
