- Kalshi sends a legal warning letter to Netflix to remove a new documentary trailer
- States the documentary trailer contains defamatory content, fabricated documents, and false statements
- The core issue is a screenshot of betting activity during a period when the company was court-ordered banned in Nevada
- Netflix insists the footage was genuinely captured at a World Cup viewing event, though the bets originated from 2025
Prediction market Kalshi sent a cease-and-desist letter to Netflix on Friday, July 25, 2026, demanding that the streaming provider immediately pull the trailer for its upcoming documentary. The company claimed that the video trailer is defamatory, filled with fabricated documents, and contains false and misleading statements.
Entitled Instadocs: The Prediction Games, the documentary chronicles the growth of the prediction market industry and features interviews with high-profile executives including Shayne Coplan, CEO of Polymarket, and Tarek Mansour, CEO of Kalshi.

However, the film's trailer centers around a party in Las Vegas where individuals who made massive profits from prediction markets gathered to watch the World Cup final. One attendee remarked that they enjoyed betting on Kalshi, while another displayed a phone screen showing a wager valued at $5,000 USD.
Netflix's Instadoc format focuses on rapid content production to capitalize on current trending events, allowing it to quickly capture a broad audience. At the same time, however, it carries risks regarding the verification of legal details and local regulations, such as licensing disputes and business operations across individual U.S. states.
The central issue is that Kalshi is currently facing a court order prohibiting it from operating in the state of Nevada. The warning letter stated that the betting screenshot shown on the phone was actually from a wager placed on May 16, 2025, long before the ban order took effect. The company argues that Netflix misled millions of viewers into believing that the individual successfully traded sports event contracts in Nevada on July 19, 2026.
Kalshi also revealed that it had spoken with a Netflix employee who agreed not to include this piece of evidence in the full documentary airing on Sunday, July 26. Despite this, Netflix refused to remove the screenshot from the trailer currently playing on the application's homepage.
Meanwhile, a Netflix spokesperson issued a statement to The Hollywood Reporter clarifying that none of the footage in the documentary was fabricated.
"The footage was filmed at the Winible World Cup Watch Weekend in Las Vegas on July 17, 2026. The trader featured with the Spain match trades displayed a betting screenshot made in May 2025, prior to any court orders in Nevada. Any bets referenced over that weekend are a matter between that individual and the app they used to trade."
