Kalshi has threatened legal action against Netflix over its documentary Instadocs: The Prediction Games, which premiered on 26 July and features an interview with Kalshi CEO Tarek Mansour.
In a Netflix-authored article about the documentary, the streaming platform said it “drops viewers into the red-hot center of betting fever” and includes interviews with industry figures such as Polymarket CEO Shayne Coplan, Mansour, and Commodity Futures Trading Commission official Michael Selig.
According to US media reports, Kalshi sent Netflix a cease-and-desist letter on 24 July, two days before the documentary’s release, alleging it contained “false and misleading statements.” The company claims a trailer for the documentary about the industry contains defamatory and “fabricated” content, according to a letter obtained by CNN.
Kalshi said a shot in the documentary’s trailer showing an influencer displaying a receipt from a Kalshi sports event contract contained “misleading statements portraying trades being made on Kalshi in violation of a court order.”
The operator says the trailer gives the impression that a trader successfully completed that transaction on Kalshi in Nevada on July 19, 2026. The company is currently barred from operating sports-related markets in Nevada under a court order stemming from a lawsuit filed by the Nevada Gaming Commission.
A spokesperson for Netflix told CNN the most prominent trade shown in the trailer was placed in 2025, long before any court orders restricting Kalshi. A spokesperson told TechCrunch that the scene was captured at a Winible World Cup Watch Weekend event in Las Vegas on July 17, 2026.
However, Netflix explained, the individual on screen had pulled up an old screenshot of a transaction completed before any Nevada court order took effect. “No footage in Instadocs: The Prediction Games was fabricated,” the spokesperson said.
But Kalshi still contends the screenshot was fabricated on the grounds that it displayed terminology such as “bet slip” that the company says has never existed on its platform.
Netflix also describes prediction markets as allowing “anyone [to] bet on anything, from the World Cup to alien invasions,” and says the documentary examines the “explosive rise of global betting.”
The documentary was released as Kalshi and other prediction market operators continue to face legal challenges at the state and federal levels.
