Legal Dispute and Cease-and-Desist Demands
Prediction market Kalshi has threatened legal action against Netflix following the release of a trailer for its upcoming documentary, The Prediction Games. Kalshi claims the footage contains defamatory and “fabricated” content, issuing a cease-and-desist letter asserting that the trailer portrays trades being made in violation of existing court orders.
The controversy centers around a trailer released by Netflix teasing the documentary, which depicts traders partying at a Las Vegas mansion while watching the recent World Cup final and touting their winnings on prediction sites like Kalshi.
Industry watchers previously highlighted that a court order resulting from a lawsuit filed by the Nevada Gaming Commission currently requires Kalshi to block sports-related markets in Nevada. While Kalshi maintains it is fully complying with judicial directives, its lawyers argue the trailer promotes misleading statements.
Netflix Defense and Broader Regulatory Scrutiny
In response to the legal threat, a Netflix spokesperson defended the project, stating that the prominent trade shown in the trailer—a $5,000 bet on Spain to win the World Cup, was actually placed in May 2025, long before any restrictive court orders. Winible, the content creator platform that hosted the Las Vegas event filmed by Netflix, stated on X that the trades were placed outside of Nevada and tracking them is legal.
However, Kalshi argued the trading slip screenshot was fabricated because it used the phrase “bet slip”, a term the company strictly avoids, as it classifies its products as derivative swap trading rather than gambling.
The dispute unfolds against a backdrop of increasing regulatory pressure on prediction markets like Kalshi and Polymarket. While regulated federally like commodity trading rather than traditional gambling, a bipartisan coalition of more than 40 states has pursued lawsuits alleging they operate as unlicensed casinos, resulting in judicial blocks in states such as Nevada, Michigan, and Washington.
Notably, Kalshi cooperated with the documentary during production, including interviews with CEO Tarek Mansour. Brandon Beckhardt, Kalshi’s head of marketing, criticized the final product, stating:
“Netflix had a chance to make a genuinely interesting documentary about prediction markets. Instead, they made a sensationalized film built on fiction”.
