Platform Market: Kalshi Wants Netflix Trailer Removed Over Alleged Defamation
Prediction market Kalshi sent Netflix a cease-and-desist letter demanding removal of the trailer for the documentary "Instadocs: The Prediction Games," alleging the trailer includes fabricated documents and false statements that mislead viewers about Kalshi's ability to operate in Nevada. The film features interviews with Polymarket CEO Shayne Coplan and Kalshi CEO Tarek Mansour. Netflix says the footage was filmed at a Las Vegas event on July 17, 2026, and acknowledges the screenshot shown was of a May 2025 bet made before a Nevada court order that later barred Kalshi from operating in the state.
A company-level legal dispute between a prediction market and a streaming service is primarily reputational and legal — limited direct impact on the wider AdTech/MarTech ecosystem.
