Hollywood studios and production companies have begun rolling out internal policies that bar employees from placing bets on prediction‑market platforms that use blockchain technology, according to a report by The Hollywood Reporter cited by Decrypt. The new rules specifically prohibit wagering on casting decisions, release schedules, box‑office earnings and other confidential entertainment data, and at least one studio has created an anonymous hotline for reporting suspected violations.

Scope of the Ban

The prohibitions mirror long‑standing insider‑trading rules that apply to securities markets, extending them to platforms such as Kalshi and Polymarket that allow users to bet on a wide range of outcomes—from who will be cast as the next James Bond to reality‑show eliminations. Penske Media, the parent company of The Hollywood Reporter, has updated its employee handbook to include bans on betting related to award nominations, production timelines and release dates.

Enforcement Challenges

Legal scholars warn that enforcing these policies could prove difficult. Joshua Mitts, a Columbia University professor who studies prediction markets, told The Hollywood Reporter that blockchain‑based betting can be “basically impossible” to trace when users employ mixers and layered intermediaries. The concern is underscored by recent incidents, such as BetOnline pulling a James Bond market after a surge of “sharp money” suggested a possible leak.

The crackdown follows several high‑profile cases involving insider betting on prediction markets. In February, a video editor at MrBeast’s company was fired and fined $20,000 after using confidential information to profit on Kalshi. Federal prosecutors have also charged a U.S. soldier and a Google engineer with fraud‑related offenses tied to Polymarket bets. State governments in California, New York and Illinois have similarly banned their employees from using nonpublic information on such platforms.

What to Watch Next

Industry observers will monitor how studios enforce the new guidelines and whether prediction‑market platforms introduce additional compliance tools. Future developments may include legal actions against insiders, further regulatory statements from state authorities, and possible adjustments to platform policies to detect and deter insider wagering.
