Lyft's main rival, Uber, is also expected to float next year.
Lyft was launched in 2012 by technology entrepreneurs John Zimmer and Logan Green, three years after Uber was founded.
However, Lyft's profile has risen over the last two years, as its larger rival was hit by controversy surrounding its aggressive corporate culture and data collection practices.
Lyft now accounts for almost 30% of rideshare revenues in the US, up from about 23% at the start of 2017, according to research firm Second Measure.
