Prediction market platform Kalshi has issued a cease-and-desist letter to Netflix, demanding the streaming giant remove the trailer for its documentary “Instadocs: The Prediction Games”. Kalshi asserts the trailer contains “defamatory” content, including fabricated visuals and misleading information about its platform.
The documentary, part of Netflix’s “Instadoc” series of rapid production films, features interviews with both Polymarket CEO Shayne Coplan and Kalshi CEO Tarek Mansour. However, the trailer prominently showcases a social gathering during the World Cup, where a trader flaunts a $5,000 bet placed via a smartphone app.
Kalshi’s legal action centers on a discrepancy: the bet displayed in the trailer was placed on May 16, 2025, predating a Nevada court ban that took effect in July 2026. Kalshi argues Netflix misrepresented the timeline, suggesting the trader successfully executed trades in Nevada after the platform’s suspension, which it claims could mislead viewers.
The company further alleges it contacted a Netflix representative who initially agreed to exclude the receipt from the final cut. Despite this, Netflix reportedly refused to edit the trailer. Kalshi’s letter states, “Netflix knowingly allowed the misleading content to remain, jeopardizing consumer understanding and its partnership with Kalshi.”
Netflix refutes claims of fabrication. A spokesperson confirmed the footage was filmed at the Winible World Cup Watch Weekend in Las Vegas on July 17, 2026, and emphasized that all trades shown were made prior to the Nevada ban. “The individual displayed their app’s historical bets, not active trades,” the statement said, attributing the screenshot to prior user activity.
The documentary’s release is slated for Sunday, July 26, coinciding with FIFA’s World Cup conclusion. Kalshi has not responded to requests for comment on Netflix’s rebuttal. Industry analysts note the dispute highlights growing friction between financial platforms and media over factual accuracy in fast-turnaround content.
