Lyft set for March market debut: report

The report said Lyft's documents for its initial public offering may be made public next week to allow the listing by late March.

That would enable Lyft, whose valuation at an estimated $15 billion makes it one of the richest venture-backed startups, to make its pitch to investors in mid-March.

The filing would put Lyft ahead of Uber, with an estimated $70 billion valuation, in the race for a public share listing that could bring in more capital and fund expansion.

Lyft has discussed the possibility of expanding globally but so far has operated only in the US and Canada.
