The books for institutional investors looking to buy the shares opened during the New York trading session today.

A 661-page draft prospectus for what looks set to be world’s biggest cross-border secondary listing shows Alibaba plans to use the money to invest in online delivery and local services platform, as well as online travel group Fliggy.

It will also spend more on developing Youku, which Alibaba says is one of the leading online video platforms in China.

The share sale, set to be Hong Kong’s largest in over nine years, is a boost for the city, which has sunk into its first recession in a decade as more than five months of street protests and worries about US- China trade war took their toll.

The progress of the protests is being monitored by Alibaba and its advisers, and is seen as a risk to the deal going ahead, according to sources with direct knowledge of the matter.

The institutional book-building for the listing will run for a week and the stock is expected to be priced on or around November 20, two sources said.

A maximum price for retail component of the deal will be announced next week, one said.

The people could not be named as the information has not yet been made public. Alibaba stock is due to start trading the week of November 25.

The company also intends to increase its investment in cloud computing and machine learning, the prospectus shows.

The Hangzhou-based company said Alibaba Cloud was currently the world’s third largest Infrastructure as a Service business, by US revenue in 2018, according to a study by Gartner.

The prospectus shows Alibaba has 960 million ‘digital economy users’ in China, including customers of its Ant Financial partnership.

The firm said its revenue was 410.8 billion renminbi for the year to June 30, 2019, and total assets on its balance sheet were worth 1.01 trillion renminbi.

Alibaba had been planning to sell the shares earlier this year, but in August postponed the deal as anti-government protests rocking Hong Kong became increasingly violent.

However, a source familiar with the transaction said Alibaba was confident it could overcome the negative sentiment in Hong Kong financial markets caused by the demonstrations.

The deal had been initially expected to raise up to $15 billion, but 500 million primary shares will now be sold in the listing. Including a typical ‘greenshoe’, or over-allotment option, to sell some extra shares, the sale could raise up to $13.4 billion.

A sale of that size would dilute existing shareholders from the company’s New York listing by 2.8 per cent, and investors would be able trade shares between the two exchanges.

The Hong Kong shares are expected to be offered at a discount of up to five per cent of the US equivalent.

At $13.4 billion, Alibaba’s share sale would rank as the world’s largest follow-on share sale targeting an entirely new stock exchange, according to data from Dealogic.
