On July 24, 2026, Kalshi, a prediction market platform, fired a cease and desist letter at Netflix, accusing the streaming giant of defamation related to a documentary trailer. The upcoming film, titled "Instadocs: The Prediction Games," contains a scene featuring a $5,000 bet placed on Spain, supposedly shown during the World Cup final weekend in Las Vegas. However, the bet slip in the trailer is dated May 16, 2025, more than a year before the footage was shot.

Kalshi’s marketing director, Brandon Beckhardt, argues the betting receipt is fabricated. He points out that the image includes the word “crop,” indicating a screenshot, and that “bet slip” is not a term used on their site. The company demands Netflix remove the trailer immediately and issue a public apology. Despite these demands, Netflix stands firm and has kept the trailer online as the documentary’s release date, July 26, approaches.

An Ongoing Standoff Over Authenticity

Netflix defends its portrayal by stating no images were fabricated, emphasizing that the footage was recorded at the Winible World Cup Watch Weekend on July 17, 2026. The bet shown was placed in May 2025, long before Nevada imposed restrictions on prediction markets. This timing is central to Netflix’s argument and could undermine Kalshi’s defamation claim.

However, ethical questions linger. Critics wonder whether showing an old bet within a new Las Vegas setting is misleading viewers by manipulating context. Legal expert Daniel Wallach highlighted contradictions in Kalshi’s position, noting that although the company says it blocked Nevada users since May 2026, transaction records indicate otherwise. These conflicting details add complexity to the unfolding legal dispute.
