Key Takeaways
- Kalshi sent Netflix a cease and desist letter on July 24, 2026, over a disputed trade slip.
- Nevada requires Kalshi to finish geofencing by August 12, 2026, or pay $120,000 daily.
- Netflix had not pulled the trailer as of July 25, ahead of the documentarys July 26 premiere.
Kalshi wants the trailer pulled and a public retraction issued before the film premieres Sunday, July 26. The company says the trailer uses a fabricated trade slip to suggest Kalshi allowed sports betting in Nevada in violation of a state court order, according to reports from The Hollywood Reporter and CNN, which obtained the cease and desist letter.
The upcoming documentary tracks the rise of prediction markets, platforms where people trade contracts tied to real events. Netflix says more than $5.6 billion moved through Kalshi and Polymarket alone on the 2026 FIFA World Cup final. Reports state that CFTC Chairman Michael Selig, Kalshi CEO Tarek Mansour, and Polymarket CEO Shayne Coplan all appear in the film, which comes from producer Words + Pictures with Steve Yaccino as showrunner.
The Disputed Scene
The trailer, released earlier this week, shows a private gathering in Las Vegas during World Cup final weekend. It has been claimed that one guest in the trailer holds up a phone displaying what looks like a Kalshi trade slip and describes a $5,000 bet on Spain, which beat Argentina 1-0 in the July 19 final.
Kalshi says the image tells a different story than the trailer implies. The receipt is dated May 16, 2025, more than a year before the events shown on screen. The phone display reads “crop,” which Kalshi says shows the person was viewing a saved image rather than an active trade. The company also says the slip does not match its interface and uses the phrase “bet slip,” language it claims has never appeared on its platform.
Kalshi marketing head Brandon Beckhardt said the company flagged the issue to Netflix before the trailer went out. “We flagged the fake trade slip to Netflix. They said they‘d pull the trailer. They haven’t,” Beckhardt said in a statement on X. He described the people in the scene as influencers rather than Kalshi traders.
Beckhardt stated:
“Netflix had a chance to make a genuinely interesting documentary about prediction markets. Instead, they made a sensationalized film built on fiction.”
Kalshi has told Netflix it has barred sports event contracts in Nevada since May 4, 2026, and argues the trailer puts that legal position at risk during active litigation with the state.
Netflix Pushes Back
Netflix denies fabricating footage in a statement shared with The Hollywood Reporter. A Netflix spokesperson said the disputed trade was placed in May 2025, before any Nevada restrictions on Kalshi existed, and that the scene was filmed at a private Winible World Cup Watch Weekend event in Las Vegas. Winible, a platform tied to sports content creators, said the trade was placed outside Nevada and that tracking a position from any location is legal.
Nevadas Regulatory Fight
The dispute sits inside a longer battle between Kalshi and the Nevada Gaming Control Board. A temporary restraining order arrived in March 2026, followed by a preliminary injunction and an amended order on May 18, requiring geofencing to block Nevada users from prohibited contracts.
Kalshi recently reached a deal with Nevada to deploy a multi-source geofencing system through a provider such as Geocomply. The company has until August 12, 2026, to finish the rollout or face penalties of $120,000 per day.
Gaming attorney Daniel Wallach pointed to a timing problem. He noted Kalshi told Netflix it has barred Nevada sports trading since early May, while court filings around the same period referenced trades that got through during the injunction period. Wallach said the overlap could weaken parts of Kalshi‘s defamation claim, which depends on the trailer’s implication being entirely false.
Why It Matters
Prediction markets grew fast in 2025 and 2026 on the back of federal clarity for event contracts and high-profile moments like elections and the World Cup. Kalshi and Polymarket now lead the U.S. market, while state gaming regulators in Nevada, Michigan, Washington and Massachusetts have pushed back with lawsuits and restrictions.
The unresolved question of CFTC authority over state gaming law now sits behind a documentary dispute with real legal weight. Kalshi cooperated with the films production, yet moved to block the trailer once it aired. As of July 25, the trailer was still circulating and Netflix had not confirmed any changes ahead of the Sunday premiere.
