Airbnb shares fell 14% after the company reported second-quarter earnings that missed analyst expectations. Airbnb warned of moderating year-over-year growth in its "Nights and Experiences" category for the third quarter compared to the second quarter. The company said it is seeing shorter booking lead times globally and signs of slowing demand from U.S. guests. Users booked over 125 million nights and experiences in the second quarter, a record high. Since launching a new quality system over a year ago, Airbnb removed over 200,000 low-quality listings.
