Uber was the ride-hailing startup that had its IPO in May 2019.
Founded in 2009 as UberCab by Garrett Camp and Travis Kalanick, the company began with smartphone-booked car rides in San Francisco and quickly expanded internationally. Its growth helped popularize app-based ride-hailing and made it one of Silicon Valley’s most prominent startups.
Uber’s registration statement became effective on May 9, 2019, and its shares began trading on the New York Stock Exchange the next day under the symbol UBER. The company priced its IPO at $45 per share and raised about $8.1 billion; the offering formally closed on May 14.
A common mix-up is Lyft, another major U.S. ride-hailing company. Lyft went public earlier, in March 2019, while Didi Chuxing and Ola followed different listing timelines and markets. Thus, the month in the question points specifically to Uber.
