Kalshi threatens Netflix following a controversial documentary
Netflix had intended to highlight the rise of prediction markets through a new documentary, but a few days before its release, the American company Kalshi accused the streaming platform of presenting inaccurate and misleading information about its business and claims to have launched an initial legal challenge to prevent the broadcast.
A statement that immediately sparked controversy
On 26 July, Netflix released ‘Instadocs: The Prediction Games’, a documentary exploring the rapid expansion of prediction markets. The programme features several industry figures, including Kalshi’s CEO, Tarek Mansour, Polymarket’s CEO, Shayne Coplan, and Michael Selig, a representative of the Commodity Futures Trading Commission (CFTC).
In its official description, Netflix explains that it aims to take viewers to the heart of what it describes as the “hottest spot in betting fever”, whilst analysing the global rise of prediction markets.
However, Kalshi claims that the documentary contains “false and misleading statements” regarding prediction markets. The company reportedly sent Netflix a formal notice on 24 July, two days before the documentary was released online. The aim of this action was to challenge the content presented by the platform and to highlight what Kalshi considers to be errors likely to damage its reputation.
A trailer at the heart of the dispute
The main point of contention concerns a short clip featured in the trailer. According to Kalshi, this shows an influencer checking a transaction made via its platform on their mobile phone. The company claims that this relates to a contract for a sporting event in May 2025, presented in a context it deems misleading. Netflix disputes this accusation, but this scene has become one of the main points of contention between the two parties.
The company also takes issue with the way Netflix presents the documentary to the public.
In its official description, the platform states that prediction markets allow “anyone to bet on anything, from the World Cup to an alien invasion”.
For several years now, Kalshi has maintained that its business does not fall within the scope of traditional sports betting or conventional gambling. On the contrary, it argues that its products are based on regulated contracts linked to events – a distinction it considers essential. To portray prediction markets as a form of generalised betting therefore amounts to misrepresenting how they work.
A debate that extends far beyond Netflix
This controversy comes against a backdrop that is already particularly sensitive in the United States. Predictive market operators are facing increasing scrutiny from the authorities. Several states are challenging the legality of contracts relating to sporting events, whilst federal authorities are continuing to consider the best way to regulate this sector.
The way in which a documentary aimed at millions of subscribers portrays this industry can therefore have a significant impact on public perception.
Netflix has not altered its portrayal
Despite the criticism levelled by Kalshi and the sending of a formal notice, Netflix went ahead with the broadcast of the documentary on 26 July.
This row comes at a time when prediction markets are playing an increasingly significant role in the US financial and regulatory landscape. Kalshi believes that the documentary contains inaccurate information that could distort people’s understanding of its business model. Netflix, for its part, has gone ahead with the broadcast of the programme despite the criticism levelled at it prior to its release.
