$143M in Suspicious Bets Raises Prediction Market Concerns in Hollywood

Entertainment companies have taken a rather unusual decision to tighten restrictions on prediction market trading, issuing clear warnings to employees using confidential information or sharing it with others. Those who do not comply with the new restrictions could risk their jobs, the companies’ warnings say. They Have It in Writing The fact that prediction markets have expanded well beyond politics and sports is no surprise, as they allow users to wager on everything from major political decisions to celebrity appearances and upcoming movie releases. However, the growing popularity of these platforms has also started to raise serious concerns across the entertainment industry, where studios are increasingly worried that employees could use confidential information to make money. According to The Hollywood Reporter, several movie studios and production companies have already sent formal warnings to employees, reminding them that trading on prediction markets using insider knowledge is prohibited. Violations could result in disciplinary action, including termination. The restrictions cover bets on sensitive industry developments such as studio earnings, casting decisions, and movie release dates. Employees are also not allowed to pass confidential information to friends or family members who might use it to place trades. Where Did It All Start? The issue is not entirely theoretical. In February, a video editor working for YouTuber MrBeast was fired after reportedly making $5,000 from prediction market trades connected to content involving the online star. The transactions attracted attention because of their unusual statistical patterns. Hollywood has also seen questions raised over betting activity surrounding the next James Bond. Prediction markets removed contracts on the casting decision after significant money was placed on actor Callum Turner, despite industry speculation pointing toward Jack Lowden. Integrity monitors reportedly raised concerns about a possible information leak. The next actor to play Bond has yet to be officially announced. Millions of Dollars on Entertainment Bets Entertainment has become one of the more active categories on prediction market platforms, following the growth of sports and political contracts. Users have traded millions of dollars on questions such as which film will win the Oscar for Best Picture, who will take the Dancing with the Stars title, and whether The Angry Birds Movie 3 will receive a Rotten Tomatoes score above 50%. Other markets are considerably more unusual, including bets on whether Donald Trump will appear on Saturday Night Live, whether Elon Musk will make a cameo in the next Superman movie, and whether Joe Rogan will join 60 Minutes as a correspondent. However, preventing employees from using private information may prove difficult. Columbia Law Professor Joshua Mitts, who studies securities law, told The Hollywood Reporter that most informed trading activity is extremely difficult to detect. Prediction market operators have their own reasons to monitor suspicious activity. If platforms become known as places where industry insiders have an advantage, ordinary customers may lose confidence in them. Rising Concerns According to Mitts’ research, approximately 210,000 suspicious bets on CFTC-regulated prediction markets have been placed between February 2024 and February 2026. Estimates say the trades generated around $143 million in profits, as the accounts recorded a win rate of 70%. The figures add to concerns about how effectively prediction markets can police insider activity as trading volumes continue to rise. The expansion of sports contracts in late 2025 helped accelerate the industry’s growth, bringing a much wider audience to platforms that now cover an increasingly broad range of real-world events.
