Airbnb intends to become a publicly traded company next year, the vacation rental company said in a news release Thursday. Airbnb hasn’t released full-year results for 2018 but has previously said its 2017 revenue was over $2.5 billion—more than 50% higher than its 2016 revenue. A number of highflying, private technology companies and other startups have made their mark on Wall Street in 2019—just not always as they intended.
