Spotify demands Kalshi and Polymarket remove their branding, stream manipulation allegations impact prediction market settlements.

Odaily Planet Daily reports that Spotify has requested prediction market platforms Kalshi and Polymarket to remove its branding and clarify that there is no partnership between the two parties. This comes after music streaming data used for platform settlements was found to have been manipulated. Spotify stated that it has removed over 500,000 "fake streams" that pushed certain songs onto the platform's trending charts and were used in a Kalshi prediction market settlement for "June's Most Popular Songs on Spotify in the US," a market with a transaction volume of approximately $3 million. Because the settlement used chart results before data correction, the relevant transactions initially identified the song as the winner. Spotify has contacted both platforms to rectify the situation after completing its investigation. Kalshi is reportedly investigating the incident, while Polymarket has not yet responded. (Bloomberg)
