Shares in Uber's largest rival, Lyft, surged 21% on their market debut in New York.
Lyft priced 32.5 million shares at the top of its $70-$72 per share target range ahead of the start of trading on the tech-heavy Nasdaq.
That valued the firm at $24.3bn (£18.6bn).
It took more than two hours for the opening price to emerge as the initial public offering (IPO) – the largest market debut since Alibaba in 2014 and a first for a ride-hailing firm – sparked a FOMO (fear of missing out) rush of interest.
Analysts explained its growth potential was seen as outweighing the fact it remains heavily loss-making.
The shares also carry no voting rights.
But they rose to $87.24 dollars when the first trades were declared.
