Kalshi challenges Netflix over prediction market documentary
Kalshi has sent Netflix a cease‑and‑desist letter on Friday, accusing the streaming giant of defamation in connection with the trailer for its upcoming documentary, Instadocs: The Prediction Games. The platform has demanded that Netflix remove the trailer, released last Thursday, and issue a public retraction ahead of the film’s scheduled premiere on 26 July. Yet the full documentary is now showing, according to a Netflix post on X.
Additionally, based on reports from The Hollywood Reporter and CNN, Kalshi alleges that the trailer features a fabricated “trade slip” suggesting the company enabled sports betting in Nevada in violation of a state court order.
Disputed footage
The documentary, produced by Words + Pictures with Steve Yaccino as showrunner, explores the rise of prediction markets. Netflix claims more than $5.6 billion flowed through Kalshi and Polymarket during the 2026 FIFA World Cup final. The film features appearances by CFTC Chairman Michael Selig, Kalshi CEO Tarek Mansour, and Polymarket CEO Shayne Coplan.
The contested trailer depicts a private gathering in Las Vegas during the World Cup final weekend. One guest is shown holding a phone with what appears to be a Kalshi trade slip, describing a $5,000 bet on Spain, which defeated Argentina 1‑0 on 19 July.
Kalshi argues that the image is misleading. It stated that the slip is dated 16 May 2025, more than a year before the events depicted. Moreover, the phone display shows the word “crop,” which Kalshi pointed out indicates the guest was viewing a saved image rather than an active trade. The company also notes that the slip uses the phrase “bet slip,” a terminology that it says has never appeared on its platform.
Company response
Brandon Beckhardt, Kalshi’s Head of Marketing, said the firm flagged the issue before the trailer’s release: “We flagged the fake trade slip to Netflix. They said they’d pull the trailer. They haven’t.” He also noted that: “Netflix had a chance to make a genuinely interesting documentary about prediction markets. Instead, they made a sensationalised film built on fiction.”
Kalshi further emphasised that it has barred sports event contracts in Nevada since 4 May 2026, arguing that the trailer jeopardises its legal position amid ongoing litigation with the state.
Netflix’s position
Netflix refuted the accusation that it manufactured the footage. It stated that the disputed trade happened in May 2025, before Nevada enforced the restrictions on Kalshi. The scene in question was filmed at a private “Winible World Cup Watch Weekend” event in Las Vegas. Winible is a platform that is connected to sports content creators. Netflix also said that the trade was placed outside Nevada and that tracking positions from any location is legal.
Regulatory clampdown
Meanwhile, the Nevada Gaming Control Board (NGCB) announced Friday that it had reached a decisive agreement with KalshiEX LLC. The agreement requires the platform to cease unlawful operations in the state or face daily fines of $120,000.
The NGCB has demanded restraining orders against the platform and other platforms for several months already by reiterating that event-based contracts constitute gambling under state law and require a Nevada Licence. Last May, the First Judicial District Court issued a preliminary injunction banning Kalshi from offering contracts tied to sports, elections, or entertainment events within Nevada.
NGCB investigators later reported accessing restricted contracts on Kalshi’s platform despite the injunction, prompting contempt proceedings. Filings allege that Kalshi facilitated hundreds of millions of dollars in wagers on marquee events such as the World Cup, NBA Finals, and Stanley Cup Finals.
Compliance deadline
Kalshi has consented to use to carry out a third-party geofencing solution that combines IP checks, GPS data, Wifi triangulation, and device signals to ban Nevada-based users. The company must comply by 12 August or face penalties of $120,000 per day.
In a formal court filing, Kalshi admitted investigators accessed restricted contracts in violation of the injunction. NGCB Chairman Mike Dreitzer underscored the Board’s stance: “The Court required Kalshi to stop offering covered event contracts in Nevada, and Kalshi violated that order. This agreement ensures Kalshi will comply with Nevada law moving forward—or face stiff penalties.”
