Kalshi threatened Netflix with a defamation suit over a recent trailer for the upcoming documentary The Prediction Games, premiering Sunday on the streamer, according to court documents and statements obtained by CNN. The dispute centers on the streamer’s promotional material for The Prediction Games, which features scenes that the prediction market app claims violate a Nevada court order restricting sports-related markets.
Cease-and-Desist Letter Targets Vegas Footage
Lawyers representing Kalshi sent a formal cease-and-desist letter to Netflix following the release of a trailer for The Prediction Games, a documentary premiering Sunday on the streaming platform, according to CNN. The legal notice asserts that the promotional footage contains misleading statements, specifically showing traders celebrating earnings from the World Cup final while partying in Sin City. According to Kalshi’s legal team, the portrayal implies trades are occurring on the app in direct violation of a court order stemming from a lawsuit brought by the Nevada Gaming Commission.
Chief Executive Officer Tarek Mansour makes an appearance in the upcoming documentary, adding high-level visibility to the project as the legal scrutiny intensifies.
Did you know? Prediction markets allow users to buy and sell contracts based on the outcome of real-world events, bridging the gap between financial forecasting and entertainment.
Netflix Defends Timeline of Featured Trades
Netflix pushed back against the defamation claims, telling CNN that the most prominent trade highlighted in the controversial trailer was executed in May 2025, well before the implementation of the Nevada court order. A company spokesperson noted that the featured trader provided a screenshot of the wager on Spain prior to any local judicial restrictions.
Kalshi’s Position
The prediction app argues the trailer contains fabricated elements, pointing to the term “bet slip” in the displayed screenshot—a phrase the platform avoids because it does not categorize itself as a gambling site.
Netflix’s Stance
The streaming network maintains that the footage accurately reflects historical user activity captured during a filming session in Las Vegas just prior to the legal restrictions taking effect.
Despite the platform’s insistence that it avoids gambling terminology, Kalshi claims the screenshot featured in the promotional video includes the phrase “bet slip.” According to the company’s legal correspondence, this terminology does not appear on its official site, deepening the dispute over the authenticity of the visual evidence used in the marketing campaign.
