Prediction markets just leaked the entire Spotify Wrapped a day early. In October, prediction markets leaked the Nobel Peace Prize winner the night before the announcement. This month, the same trick leaked Spotify Wrapped’s top artists. Just like Nobel site, The Spotify Newsroom blog is run on WordPress. If you know where to look, you can query when they upload new images to the media library. Anyone who studied previous years would know that Spotify uploads the Wrapped graphics there before the blog post going live. So if you’re watching that feed, you can see tomorrow’s “big reveal” today, and trade on it before any public announcement. All year, Spotify’s streaming numbers are public, so most of the prediction markets on the event were already trading above 90%, but one ranking was a big surprise. Drake was on track to finish as the #3 artist globally, ahead of the Weeknd by over 2 billion streams. On the leaked graphic, he suddenly shows up at #4. This is likely tied to Spotify’s recent lawsuit over botted streams. It looks like they filtered out a huge chunk of Drake’s streams. The market on Drake was trading >95% yesterday morning and then began to dump and this image hit the site and traders discovered it. I got rinsed because I assumed the streaming numbers were static. Turns out Spotify can (and did) rewrite the data. Spotify wrapped officially drops tomorrow, but if you take a quick online web scraping course, you can figure out the whole list a day early!
