Chinese internet giant Alibaba has filed documents for a public share sale in the US, which is widely expected to be one of the biggest public offerings in history.
The company said it was seeking to raise $1bn (£589m). But that figure is seen just as an estimate to calculate various fees.
Analysts expect it to raise more than $15bn and top Facebook’s share sale.
Alibaba did not disclose details of the number of shares it intends to sell or their price range.
