If you count Spotify users who stream for free on the ad-supported platform, then Spotify counts around 140 million active users.
Last year, Spotify was valued at around $19 billion and has started 2018 with a confidential filing with a confidential filing with the U.S. Securities and Exchange Commission (SEC) for an IPO. Spotify is targeting a direct listing at some point in Q1 2018.
