US film studios and television production companies are reportedly tightening their rules to stop employees from using confidential information to trade on prediction markets.

According to The Hollywood Reporter, studios and production companies have issued guidelines banning staff from trading on events linked to their work, including studio earnings, casting, and release dates.

Employees are also barred from passing inside information to friends or relatives so they can bet on prediction markets instead. At least one company has reportedly set up an anonymous reporting hotline for suspected violations.

Penske Media, The Hollywood Reporter’s parent company, has also updated its employee handbook to ban bets on award nominations, casting decisions, production timelines and release dates.

While the Onion Futures Act of 1958 bans futures contracts on movie box office receipts, prediction markets are increasingly covering other entertainment-related events, such as reality TV shows and casting decisions.

This creates additional challenges for studios seeking to prevent employees from using confidential information to make trades.

In February, Kalshi said a video editor working for MrBeast had made about US$5,000 trading on markets tied to the creator’s videos using non-public information. Kalshi fined him around US$20,000 and banned him for two years.

In April, a Puck columnist wrote that he knew someone working on a CBS competition show who was making extra money on prediction apps.

A March study by Columbia University law professor Joshua Mitts and University of Haifa researcher Moran Ofir estimated that traders had generated around US$143 million in anomalous profit on prediction market Polymarket over a two-year period, based on suspicious trading patterns, though Mitts stressed that the screen does not prove anyone acted on improper information.

Mitts told The Hollywood Reporter that many more employers now have to think about insider trading rules, and that tracing insiders on blockchain-based platforms can be “basically impossible” when users hide their identities.

In June, the Commodity Futures Trading Commission (CFTC) sought public comment on whether reality TV contests should be classed as “gaming.” Award shows were excluded from the question, while game shows and talent contests remain uncertain.

The developments come as prediction market operators are also facing legal action from multiple states, with Arkansas Attorney General Tim Griffin recently suing Kalshi and VGW over alleged illegal gambling.

The Backstory

Prediction markets move from politics to pop culture

The entertainment industry’s effort to restrict employee trading on prediction markets marks a new stage in a broader fight over event contracts, confidential information and the line between regulated derivatives and gambling. What began as a debate centered on elections and sports has expanded into film, television, streaming and creator-led media, where production schedules, casting decisions and award campaigns can carry market value before they become public.

Studios and production companies are responding because prediction markets have become more granular. Platforms are no longer limited to high-profile political contests or macroeconomic events. Traders can now seek exposure to outcomes tied to reality shows, talent contests, celebrity moves and release calendars. That creates obvious risks for businesses built around secrecy. A junior staffer, editor, talent booker or postproduction vendor may know the result of a contest, a casting decision or a delayed release weeks before the market does.

The stakes are not only reputational. If employees use nonpublic information to trade event contracts, entertainment companies could face questions from regulators, unions, business partners and insurers about whether they took adequate steps to protect confidential information. The emergence of internal bans, handbook changes and whistleblower channels shows studios are treating prediction-market trading less like casual betting and more like a compliance risk.

Kalshi cases gave employers a warning

The entertainment crackdown follows a series of insider-trading episodes that showed how quickly nonpublic information can be converted into profit on event markets. In one high-profile case, Kalshi said an editor working for YouTube creator MrBeast traded on markets tied to the creator’s videos using information that had not yet been released publicly. The platform fined the trader and imposed a suspension.

That case has become a reference point for studios because it translates directly to film and television production. Editors, producers, contestants, assistants, publicists and contractors often know outcomes long before viewers do. A market tied to a reality show result, casting reveal or production delay could be vulnerable to the same kind of information leakage.

The Commodity Futures Trading Commission has also been trying to clarify its role. In a related enforcement statement, the agency reaffirmed its authority to police prediction markets after Kalshi uncovered insider trading, saying it can act against misappropriation of confidential information, fraud, manipulation, wash sales and other abusive practices. The agency said some matters had been handled internally by the exchange but stressed that federal oversight still applies.

That position matters for entertainment companies. If the federal derivatives regulator views misuse of confidential information as within its remit, employers have an added incentive to set clear internal rules. The goal is not only to prevent staff from trading but also to show regulators that the company took reasonable steps to control access to sensitive information and prohibit improper use.

Sports became the first integrity test

Sports offered an early preview of how industries can respond when event contracts grow around their core product. Leagues have spent years building monitoring systems around sports betting. Prediction markets add another layer because they may be offered through federally regulated derivatives venues rather than state-licensed sportsbooks, raising questions about who has authority and what rules apply.

The NHL’s recent integrity agreement with the derivatives regulator showed one model for managing that risk. The league signed an information-sharing deal with the Commodity Futures Trading Commission to coordinate on hockey-related event contracts, including confidential information sharing and regular meetings. Reuters reported the agreement was designed to protect market participants from insider trading, fraud and other abuses through cooperation between the league and regulator.

Entertainment companies do not have the same centralized league structure, making the challenge more fragmented. A major studio may control its own productions, but a reality program can involve outside producers, postproduction houses, contestants, marketing agencies and distribution partners. A leak can come from any point in that chain. Unlike a sports league, there may be no single industry body positioned to negotiate marketwide integrity agreements.

That makes company-level policy more important. Bans on trading, restrictions on tipping friends or relatives and anonymous reporting mechanisms are practical attempts to replicate, inside each company, some of the controls sports bodies are developing with regulators and exchanges.

Federal licenses draw new entrants

The compliance challenge is growing because prediction markets are attracting larger and more sophisticated operators. Crypto exchange Kraken’s agreement to buy Small Exchange, a Commodity Futures Trading Commission-licensed contract market, underscored the strategic value of federal market infrastructure. The company said the acquisition would support a US-native derivatives offering, and a spokesperson confirmed interest in the prediction market sector.

That deal, described in Kraken’s move toward prediction markets through its Small Exchange acquisition, reflected a broader push by trading, crypto and gaming-adjacent companies to use federal derivatives licenses to enter event contracts. Kalshi has expanded aggressively, while other operators have explored National Futures Association approvals or designated contract market applications.

As more regulated infrastructure enters the field, the number of tradable events is likely to expand. That may bring deeper liquidity, more institutional interest and better surveillance tools. It also increases the incentive for insiders to monetize private knowledge. The entertainment sector is especially exposed because many outcomes are known internally long before the public sees them, and some are binary enough to fit neatly into event-contract formats.

State regulators have pushed back, especially where sports contracts resemble wagering. But entertainment contracts raise a different problem. They may not look like conventional sports betting, yet they can still create markets where insiders have decisive advantages. That is why studios are moving before a major scandal forces a regulatory response.

Political markets sharpen the fairness debate

The same concerns have surfaced in politics, where access to information can be unequal and market moving. The launch of a paid Truth Social data product prompted criticism from lawmakers who argued that faster access to posts from high-ranking accounts could give institutional subscribers an unfair edge. The debate, covered in concerns over Truth API and insider trading risks, highlighted how prediction markets can amplify disputes over privileged information.

Political markets have already produced examples involving government employees, public officials and people close to market-moving events. Those episodes matter to Hollywood because they show regulators, employers and exchanges are facing the same structural issue across sectors: prediction markets create prices around future events, and people with early access to outcomes or influential information may be tempted to trade.

Goldman Sachs and other financial firms have responded by restricting employee trading on contracts linked to their business interests. Studios are now adapting that logic to entertainment. For both industries, the rule is straightforward: employees should not use information gained through work to trade against the public.

A compliance problem without clean boundaries

The unresolved question is how far the rules should go. The Commodity Futures Trading Commission has sought public input on whether reality television contests should be treated as gaming, while award shows and other entertainment events remain less clearly defined. The Onion Futures Act already bans futures contracts on movie box-office receipts, but that does not address the wider set of entertainment-linked markets now emerging.

That leaves studios managing risk in a gray zone. A contract on a casting decision, release date or award nomination may not be a box-office future, but it can still depend on information held by a small group of insiders. Blockchain-based or pseudonymous platforms can make tracing those insiders difficult, particularly if traders use intermediaries or pass information to friends and relatives.

The result is a defensive shift. Entertainment companies are building internal policies before regulators create a complete framework. Their immediate aim is to protect confidential information, avoid market-abuse allegations and reassure partners that productions will not become trading opportunities for insiders. As prediction markets continue to expand, Hollywood’s response may become a template for other industries whose private decisions are increasingly being turned into tradable events.
