Chinese e-commerce giant Alibaba Group Holding has received enough orders for its looming US floatation, covering the entire deal within just two days of its launch, according to a report.
There was no indication as to where most of that demand was in the $60 and $66 apiece indicative range for the NYSE initial public offering (IPO), Reuters reported.
Pursued by the news agency, Alibaba refused to comment.
Co-founder and executive chairman Jack Ma has spoken with potential investors in New York and Boston this week, presenting his company's growth strategies and addressing concerns surrounding its corporate governance.
Alibaba launched its IPO on 8 September and is expected to price the deal on 18 September.
The Alibaba share sale will raise $21.1bn (£13.1bn, €16.3bn) at the top end of expectations. That figure exceeds Facebook's $16bn listing in 2012 as the largest-ever technology IPO.
The planned listing will value the firm, which handles more e-commerce than Amazon.com and eBay combined, at about $162.69bn at the top end.
Alibaba could also set a new record for the world's biggest IPO if underwriters exercise an option to sell additional shares to meet demand - putting it as high as $24.3bn and topping Agricultural Bank of China's $22.1bn listing in 2010.
