Kalshi Sends Cease-and-Desist Letter to Netflix
Kalshi, a prediction market company, has sent a cease-and-desist letter to Netflix demanding that the streaming service remove the trailer for an upcoming documentary, "Instadocs: The Prediction Games".
Kalshi Claims Trailer is Defamatory
The trailer, which was released on Friday, features interviews with both Polymarket CEO Shayne Coplan and Kalshi CEO Tarek Mansour. However, Kalshi claims that the trailer is "defamatory" and contains "both fabricated documents and false and misleading statements".
The trailer focuses on a recent party in Las Vegas, where men who have "made millions of dollars on prediction markets, probably eight figures, just over the course of the World Cup" have gathered to watch the World Cup final. One of the guests declares, "I like betting on Kalshi," while another shows off an apparent $5,000 bet on their phone.
However, Kalshi is currently banned from operating in Nevada due to a court order. In its cease-and-desist letter, Kalshi said the bet shown on the phone is actually a screenshot of a bet made on May 16, 2025 — long before the ban. But the company argued that in the trailer, Netflix "misled its millions of customers into believing this individual was able to successfully trade sport event contracts in Nevada on July 19, 2026."
Netflix Refuses to Remove Trailer
Kalshi also claimed that it recently spoke to a Netflix employee who "agreed not to feature the receipt in the documentary when it is released" on Sunday, July 26. However, despite Kalshi demonstrating to this employee that the claims in the video were demonstrably false, Netflix inexplicably refused to remove the receipt from the trailer currently circulating on the homepage of the Netflix app.
Netflix claims that none of the documentary footage was fabricated, and that the featured trader with the trade on Spain showed them a screenshot of his bet, which was made in May 2025 prior to any Nevada court order.
