Skadden, Arps, Slate, Meagher & Flom and Simpson Thacher & Bartlett have the lead roles on Chinese ride-hailing giant Didi Chuxing’s $4.4 billion initial public offering on the New York Stock Exchange.

Beijing-based Didi debuted on Wednesday, priced at the top of the range, valuing the company at $73 billion. The deal is the largest U.S. share sale by a Chinese company since Alibaba’s blockbuster $25 billion New York listing in 2014.
