The number of active Lyft riders has surged fivefold to 18.6 million in the fourth quarter of 2018, from the first quarter of 2016, and those numbers are set to rise further, Citron said, listing several other reasons to not be short on Lyft.
As of Thursday, Lyft’s short interest was $937 million, with 13.38 million shares shorted, which makes up about 41.2 percent of its float, according to data from S3 Partners, a financial technology and analytics firm.
