Netflix is facing the threat of a defamation lawsuit from prediction market platform Kalshi, which claims a trailer for an upcoming documentary about betting markets falsely implies the company violated a court order barring it from offering sports wagering contracts in Nevada.

Kalshi's attorneys sent Netflix a cease-and-desist letter demanding the streamer immediately pull the trailer for the documentary, titled Instadocs: The Prediction Market Games, and issue a public retraction.

The company argues the promotional clip misrepresents a scene filmed during a World Cup watch gathering in a way that suggests one of its users placed a live sports bet on the platform in Nevada this year, something Kalshi is currently prohibited from allowing under an injunction tied to ongoing litigation with state gaming regulators.

The scene in question, according to the letter, shows a group of people gathered at a residence in Nevada discussing prediction markets during the 2026 FIFA World Cup. At one point, a participant displays what looks like a transaction receipt from Kalshi on his phone and tells the group he wagered $5,000 on Spain to win the tournament.

Kalshi contends the trailer's framing, paired with references to the ongoing World Cup, creates the false impression that the wager was placed in July 2026, directly contradicting a standing court order that bars the company from offering Nevada residents sports event contracts.

Kalshi's letter lays out several details it says prove the receipt shown on screen wasn't a live transaction at all. The company points out that the image bears a timestamp of May 16, 2025, well over a year before the World Cup gathering depicted in the trailer took place. Kalshi's lawyers also note that the phone screen visibly displays the word "crop" in the corner of the image, which they argue is a telltale sign the man was scrolling through a saved screenshot rather than actively placing a bet through the app in real time.

The company says it raised these concerns directly with a Netflix staffer involved in editing the trailer before pursuing legal action. Per the letter, that employee admitted to not having realized the receipt was more than a year old or that it showed a cropped, static image rather than a live wager.

Despite that acknowledgment, Kalshi says the employee confirmed the receipt would be excluded from the final cut of the documentary but declined to pull it from the trailer, even after being warned the footage could complicate Kalshi's position in its Nevada court battle.

Kalshi says that warning proved prescient once a CNN reporter reached out to the company afterward, seeking clarification on where and when the bet shown in the trailer had actually been placed.

The company argues that Netflix's decision to keep the clip in circulation after being alerted to the alleged inaccuracies amounts to actual malice, a key legal threshold plaintiffs must clear to win defamation claims involving matters of public concern.

Netflix has pushed back firmly on the allegations, maintaining that nothing in the documentary was staged or fabricated. A company spokesperson said the footage was captured at a World Cup watch event held in Las Vegas on July 17, 2026, and that the trader seen discussing his Spain wager showed producers a screenshot of a bet he had placed in May 2025, before the Nevada court order took effect.

Netflix further stated that any specific bets referenced by attendees during the gathering were transactions between those individuals and whatever platform they used, distancing the company from any claim that the trade itself occurred during the restricted window.

Neither Kalshi nor Netflix has indicated whether the dispute will proceed to formal litigation.
