The Kalshi Spotify streaming market debacle has produced an unusual casualty: Spotify’s own branding. The streaming platform has demanded that both CBS News-confirmed prediction market operators, Kalshi and Polymarket, strip its logo from their platforms and clarify that no commercial partnership exists between them and Spotify.
The demand follows a chain of events that exposed a direct exploit vector between stream manipulation and prediction market settlement. Traders appear to have purchased positions on which song would be the most-streamed U.S. track on Spotify in June, then artificially inflated plays to move the outcome in their favour.
How the Kalshi Spotify Streaming Market Was Gamed
The target was Malcolm Todd’s track ‘Earrings.’ According to Music Business Worldwide, streams of the track climbed roughly 70% in a single day, reaching No. 1 on the U.S. chart on 29 June. Spotify detected and removed more than 500,000 artificial streams, dropping ‘Earrings’ from first place to No. 4 on the chart, per NME citing a WIRED report.
Kalshi, which operates as a designated contract market (DCM) regulated by the Commodity Futures Trading Commission (CFTC), had already settled its market on the outcome before the manipulation was uncovered. The June Spotify chart market drew around $3 million in trading volume, according to Music Business Worldwide citing Bloomberg.
A Spotify spokesperson told CBS News: ‘Spotify has best in class detection and mitigation practices for manipulated streams, and we don’t pay out associated royalties.’ A Kalshi spokesperson confirmed the company is ‘in touch with Spotify’ and investigating the matter.
Caleb Davies, a trader who estimates he has made $1.2 million across prediction markets, publicly accused Kalshi of settling the market despite repeated warnings that Todd’s sudden rise in the rankings warranted investigation. He alleged the platform continued offering liquidity rewards tied to the affected contract while aware of suspicious conditions, and questioned whether fee revenue was prioritised over addressing the manipulation.
Regulatory Pressure on Prediction Markets Is Widening
The episode lands as the CFTC tightens its grip on the sector. The regulator has an open investigation into Polymarket that spans multiple areas of the platform’s business, including its social media operations, following a Wall Street Journal report on staged trading videos used to recruit users.
Polymarket’s regulatory history with the CFTC runs deeper than the current probe. The regulator issued a cease-and-desist order against Polymarket (then operating as Blockratize, Inc.) in January 2022, finding the platform had violated the Commodity Exchange Act by operating an unregistered market beginning no later than June 2020.
The CFTC is also pursuing broader rulemaking. Its Advance Notice of Proposed Rulemaking on prediction markets addresses insider trading and manipulation concerns; the regulator is accepting public comments through 31 July. The notice observes that prediction market contracts may fall within the Commodity Exchange Act’s definitions of swaps or futures, a categorisation with significant compliance implications for operators.
State regulators have also continued to push back, arguing certain prediction contracts function as unlicensed sports betting products. The CFTC has filed lawsuits against several states, asserting federal preemption over DCM-regulated markets.
Spotify’s extension of the logo-removal demand to Polymarket reflects a straightforward concern: any market tied to streaming chart performance creates a financial incentive to inflate play counts, regardless of which platform hosts the contract. With the CFTC’s comment window open and manipulation already on the record, the structural question for prediction market operators is how to settle real-world-data markets without handing participants a direct manipulation lever.
