Studios Ban Insider Bets
Major entertainment firms are updating handbooks to stop employees from wagering on trade secrets and industry news.

Major film studios and production houses are rewriting employee rules to stop staff from betting on industry news. The new guidelines target prediction market wagers on specific events like casting picks, movie release dates, and studio financial results. This move expands older insider trading bans to cover modern digital betting platforms. Companies aim to protect confidential information in an era where speculation is easy and accessible.
The rules go beyond what an individual employee does. Staff are now barred from sharing inside information with friends or family members who might use it to place bets. At least one firm set up an anonymous hotline for workers to report suspected violations by coworkers. This step shows how seriously executives take the new standards and the need for active enforcement.
Columbia University law professor Joshua Mitts says these platforms forced employers to rethink ethical guidelines. He notes the main challenge is now compliance and education rather than criminal prosecution. Employees need to understand what is allowed when they are not facing a court case. The goal is to clarify boundaries for workers who hold sensitive trade secrets.
PMC, the parent company of The Hollywood Reporter, updated its own handbook to match this industry trend. The new text explicitly bans betting on award nominations, casting decisions, and production schedules. This aligns the news outlet with its peers in curbing speculative activity among insiders. The change reflects a wider shift in how the entertainment sector handles internal data.
Recent cases have shown why these rules are necessary. In February, the platform Kalshi reported that a video editor at MrBeast's company made $5,000 using secret content details. The worker was fired and fined $20,000. A separate report in April identified a CBS competition show employee who also profited from prediction markets. These incidents proved that improper betting is a real financial risk for studios.
This week, BetOnline temporarily paused its market for the next James Bond actor. The site cited a surge in bets favoring Callum Turner over the previous favorite. A representative suggested the sudden shift in odds pointed to a potential leak after recent auditions. The suspension highlights the difficulty of distinguishing between informed insiders and lucky public bettors.
A study by Mitts and Moran Ofir of the University of Haifa found $143 million in anomalous profit on Polymarket over two years. They believe that number has likely grown as more betting categories appeared. Mitts argues that betting on entertainment news offers little social utility compared to other market hedging tools. The Commodity Futures Trading Commission is currently weighing in on which events should be eligible for trading. It remains uncertain how game shows and reality competitions will be classified due to varying fairness standards.
