The ridesharing market has seen significant growth in recent years. A survey of almost 11,000 people in the U.S. indicated that 36 percent of people used ride sharing services in 2018, an increase from 15 percent in 2015. The largest two companies in the U.S. ridesharing market are Uber and Lyft, which reported net revenue in 2018 of 11.3 billion U.S. dollars and 2.6 billion U.S. dollars respectively.
In terms of ridership, Uber has a larger share in the United States than Lyft, with 119.2 million users in the first three months of 2018 compared to 76.5 million for Lyft. However, this doesn't reflect the extent to which the gap between the two companies closed during the quarter. In January 2018, Lyft reported 16 million users compared to 38.7 million users for Uber, whereas by March 2018 Lyft’s ridership had increased to 32 million, while Uber’s ridership had only increased to 41.8 million.
