On July 26, Netflix released a new documentary on prediction markets exploring the fast-growing world of prediction markets.
The documentary features interviews with several prominent figures in the industry, including Kalshi chief executive officer Tarek Mansour, Polymarket chief executive officer Shayne Coplan, and Michael Selig of the Commodity Futures Trading Commission.
Kalshi, however, does not seem to like the way “Instadocs: The Prediction Games” came out, as the company is now threatening legal action against the streaming platform.
The “Red Hot Center of Betting Fever”
In promotional material published by the streaming giant with 320 million subscribers, the streaming giant explained the documentary is meant to carry viewers into the “red hot center of betting fever” while assessing the explosive rise of prediction markets around the world.
However, Kalshi believes that Netflix’s portrayal of the industry is not accurate and, even more, could potentially damage the company.
According to multiple reports, Kalshi sent Netflix a cease-and-desist letter on July 24, just two days before the official release date of the documentary, alleging that it contains “false and misleading statements.”
Trailer and Wording Issues
At the core of the dispute seems to be a brief scene in the trailer that reportedly shows an influencer displaying a Kalshi transaction on their phone.
Kalshi claims the image depicts a sports event contract dating back to May 2025 and suggests it has been presented in a misleading context, allegations which Netflix has denied.
However, the disagreement appears to extend beyond that one scene in the trailer. In its official description of the documentary, Netflix states that “prediction markets let anyone bet on anything, from the World Cup to alien invasions.”
That wording has, as expected, drawn criticism because companies such as Kalshi have long argued that prediction markets are fundamentally different from traditional sports betting and gambling, instead operating through regulated event contracts.
The timing of the new development is particularly notable as prediction market operators keep facing growing legal and regulatory scrutiny in the United States, with many states challenging the legality of sports-related event contracts and federal agencies continuing to look into the best ways to regulate the sector.
