I see tremendous upside getting into either $LYFT below $20B or $UBER at $120B, which recently announced operational air taxi service by 2023.
Ride hailing is a commodity.
Uber has had to close down operations in several countries as well as several cities here in U.S.. Each time losing investors hard earned dollars. Lyft is most definitely, as others mentioned, in the slipstream; benefiting from Ubers successes and failures.
Lyft is a brand people respect and love and Uber not so much; at least not here in the U.S.
Lyft also has partnered with Google's Waymo. I think that partnership is limited to testing autonomous ride share but Google is also an investor in Lyft. A future acquisition or partnership doesn't seem out of the question. I see room for a few players to own the market and if I were an investor I'd go with Lyft.
