In the race to go public, Lyft just officially took the lead.
The company has officially submitted a registration statement for an initial public offering (IPO) with the U.S. Securities and Exchange commission.
TheStreet reported that the move is a first step toward becoming a publicly traded company. Lyft didn't specify how much it is seeking to raise or how much it believes it is worth, though it did state in June that it believes it is worth approximately $15.1 billion.
The company also didn't specify the number of shares it plans to offer, or the price range for them.
Following a $1.5 billion funding round last year, Lyft brought on board Kristina Omari as its first-ever vice president of corporate development and investor relations - a sign that it was looking to move toward being a publicly traded company.
Larger rival Uber Technologies Inc. is widely anticipated to also move forward with an IPO. Uber has said that it hopes to garner a market value of more than $100 billion.
