Prediction market Kalshi has demanded that Netflix remove the trailer for its upcoming documentary Instadocs: The Prediction Games
, alleging it contains defamatory and fabricated content regarding sports betting in Nevada. The dispute erupts just days after more than $5.6 billion was wagered on the World Cup final.
Netflix is expanding its rapid-turnaround documentary series with an installment focused on the explosive growth of prediction markets. Yet before Instadocs: The Prediction Games premieres on Sunday, July 26, the streaming giant finds itself at the center of a legal showdown with one of the industry’s most prominent platforms.
The controversy centers on a promotional trailer released on Thursday. The preview features influencers gathered in a Las Vegas home during the 2026 FIFA World Cup, discussing their wagers on prediction websites. At one point, a participant holds up what appears to be a transaction receipt and tells the camera he put $5,000 on Spain to win the tournament.
Kalshi’s Defamation Claims and the Nevada Court Battle
For Kalshi, the trailer’s depiction of users trading sports event contracts in Nevada is not just dramatic flair—it is a direct threat to the company’s legal standing. Under a court order following a lawsuit brought by the Coingape, Kalshi is barred from offering sports-related contracts to users within the state. The company argues that the trailer creates the false impression that users successfully traded sports contracts on its platform in Las Vegas on July 19, 2026, directly violating the court order.
In a cease-and-desist letter sent on Friday, Kalshi’s head of litigation, Jovalin Dedaj, asserted that the preview contains false and misleading statements
that jeopardize the platform’s ongoing legal fights. Furthermore, Kalshi executives pointed out technical discrepancies in the displayed transaction slip. Marketing lead Brandon Beckhardt stated that the featured trade receipt is completely fabricated
and bears no resemblance to the platform’s actual user interface, suggesting it was either photoshopped or generated using artificial intelligence.
“Netflix had a chance to make a genuinely interesting documentary about prediction markets. Instead, they made a sensationalized film built on fiction.”

According to Kalshi’s legal team, representatives spoke with a Netflix trailer editor who acknowledged that the receipt was a cropped screenshot dated May 16, 2025—more than a year prior to the Nevada restrictions and the events filmed in the documentary. While the employee allegedly agreed to keep the receipt out of the final feature film, Netflix declined to remove it from the promotional trailer.
Netflix Defends Its Footage
Netflix has pushed back firmly against the allegations of fabrication. While the streaming service does not dispute that the transaction screenshot originated in 2025, a company spokesperson insisted that no documentary footage was manufactured for the project.
“The footage was filmed at the Winible World Cup Watch Weekend in Las Vegas on July 17, 2026. The featured trader with the trade on Spain showed us a screenshot of his bet, that was made in May 2025 prior to any Nevada court order. Any specific trades or bets referenced during that weekend are between the individual and the app in which they placed the trades.”

The Massive Stakes Behind the Streaming Spotlight
Beyond the legal sparring, Instadocs: The Prediction Games arrives during an unprecedented financial surge for alternative wagering platforms.
While federal regulators like Commodity Futures Trading Commission head Michael Selig classify these platforms under commodity trading rather than traditional gambling, a bipartisan coalition of more than 40 states is challenging that distinction. Courts in states like Washington, Michigan, and Nevada have already intervened to block specific market activities.
The documentary itself, produced by Words + Pictures with showrunner Steve Yaccino, features interviews with industry leaders including Polymarket CEO Shayne Coplan and Kalshi CEO Tarek Mansour. It explores whether crowdsourced forecasting serves as an honest public thermometer or a playground for manipulation where deep-pocketed actors can sway outcomes ranging from elections to armed conflict.
Whether Kalshi pursues formal courtroom action or if the dispute settles before the credits roll on Sunday, the controversy has ensured intense viewer interest in Netflix’s latest project as it goes live.
