Kalshi threatens to sue Netflix over documentary
Kalshi initiated a legal conflict with Netflix by demanding the removal of the trailer for its upcoming documentary, The Prediction Games, considering that it contains false claims that could affect its reputation with users, regulators, and commercial partners. The dispute centers on a scene in the preview where participants at a party in Las Vegas show alleged winnings obtained through the platform's sports contracts during the 2026 World Cup final, a sequence that, according to the company, creates the impression that it allowed sports operations in Nevada despite a court order restricting that type of activity in the state.
In a cease and desist letter sent to Netflix, Kalshi asserted that the trailer includes fabricated documents and misleading statements. The company maintains that the screenshot shown corresponds to an operation carried out in May 2025, before the judicial restrictions, and that the material would have been presented in a way that leads to an incorrect interpretation. Netflix rejected the accusations and defended the production. A spokesperson assured that the documentary complies with the platform's journalistic standards and denied that any element had been manipulated, explaining that the operation shown was carried out before the prohibition imposed by Nevada and that the images were recorded during an event held in Las Vegas in July 2026.
The documentary is part of the Instadocs series and analyzes the growth of prediction markets, a segment that has gained relevance in the United States in recent months. The production includes interviews with Kalshi's CEO, Tarek Mansour, and with the CEO of its main competitor, Polymarket, Shayne Coplan. The controversy reflects one of the industry's central discussions: whether prediction markets should be considered financial products regulated as derivatives or if, when offering contracts linked to sports, they function in practice as a form of sports betting.
Companies like Kalshi and Polymarket argue that their products do not belong to the gambling sector and avoid terms like "bet" or "sports betting," while various state regulators argue that these platforms can operate as unlicensed casinos when they allow trading contracts linked to sports outcomes. The traditional gambling industry has also begun to get involved in the debate, considering that sports prediction markets represent direct competition for regulated sports betting operators.
In parallel to the dispute with Netflix, Kalshi reached an agreement with the Nevada Gaming Control Board to implement a geolocation system that prevents users located in that state from accessing its sports contracts. The company must complete the process before August 12 and, if not, will face a penalty of $120,000 per day until the block is operational. The agreement came after investigators from the regulator managed to access the platform's sports contracts from Nevada despite the court order limiting those operations, something the company itself had acknowledged in court.
