Box office prediction markets let you take a position on how much a film will earn at the domestic box office, which film will have the biggest opening weekend, or which title will be the highest-grossing release of the year. Each contract is a Yes/No question on a specific revenue outcome, priced between $0.01 and $0.99, and resolves on official box office data from industry sources.
This page covers the best sites for box office prediction markets, how the different contract types work, what drives opening weekend estimates, and how to get started.

Polymarket runs the deepest box office prediction market catalog, with 111 active markets and $14.7M in cumulative trading volume. The lineup covers opening weekend revenue brackets for individual films, year-long highest-grossing film contracts, and cumulative domestic gross milestone questions. Opening weekend contracts use a bracket structure, asking whether a film will gross within a specific range: under $50M, $50-85M, $85-115M, $115M and above, and so on. Markets resolve on official data from The Numbers and Box Office Mojo, with both sources required to confirm final figures before resolution closes. The community chat on each market page tends to be particularly active during the week of a major release as tracking estimates update daily.
New users who deposit $20 or more receive a $50 trading bonus, the strongest welcome offer on this page. The Polymarket iOS app covers the full box office catalog and includes live price charts that update as tracking data shifts in the days before a wide release.

How Box Office Prediction Market Contracts Work
A box office contract is a Yes/No question on a specific revenue outcome. A typical opening weekend contract might ask "Will this film gross between $85M and $115M on its opening weekend?" You pick Yes or No, pay between $0.01 and $0.99, and receive $1 if correct or $0 if not. For a fuller explanation of how event contracts work, see our guide on how prediction market contracts are structured.
The price reflects the market's collective view of the probability. If a $85-115M bracket is priced at $0.48, the market is placing roughly a 48% chance of the film landing in that range. As tracking data updates through the week, as presale figures arrive, and as early screening word of mouth spreads, the contract prices shift. You can sell at any point before the market resolves at the current price.
Types of Box Office Contracts Available
Box office markets cover several distinct outcome types, from a single film's opening weekend to full-year competitive questions. For the broader culture prediction market landscape, see our culture prediction markets hub.
Opening weekend revenue brackets
The most common box office contract type. A film's opening weekend domestic gross is divided into revenue ranges and a contract runs on each bracket. The bracket structure creates a natural probability distribution: all active brackets for the same film should sum to roughly 100% probability, so reading the full set gives you a quick view of where the market concentrates its expectation for the opening number.
Highest opening weekend of the year
A competitive market asking which film will post the biggest single opening weekend over the full calendar year. These run for the entire year and reprice as tentpole releases approach and post their actual numbers. Major franchise releases tend to dominate trading in this category.
Highest grossing film of the year
A longer-dated market asking which title will finish the year with the highest cumulative domestic or worldwide gross. Unlike the opening weekend market, this one stays open throughout the year and responds to each film's actual legs in the weeks after release. A film with a massive opening but poor reviews tends to drop quickly; a film that opens modestly and builds through word of mouth can stay competitive for months.
Cumulative domestic gross milestones
Contracts asking whether a specific film will exceed a total domestic gross threshold (for example, will it cross $300M domestically?) by a set date. These suit traders who have a view on a film's long-term audience appeal rather than just its opening weekend.
International and worldwide gross contracts
Markets asking about total worldwide or specific international territory performance. These are most common for franchise films where international markets, particularly China, can significantly outpace or underperform domestic expectations.
How Box Office Contracts Settle
Settlement uses official industry tracking sources. Polymarket's box office contracts resolve based on The Numbers figures for the 3-day domestic opening weekend, typically including Thursday preview earnings. The contract stays open until both The Numbers and Box Office Mojo have confirmed their finalized figures, which usually happens by Sunday evening or Monday morning following the opening weekend.
The 3-day figure versus the 4-day figure (for holiday weekends) can matter for contracts that fall across a long weekend. Always check whether the specific contract measures the 3-day or 4-day number. For annual grossing contracts, resolution typically waits until both sources confirm the year-end rankings, which can extend into early January.
What Drives Box Office Contract Prices
Box office prediction markets respond to a specific information flow that builds through the weeks before a film's release and accelerates dramatically in the final 72 hours. For more on how prediction markets price future events generally, see our Kalshi versus Polymarket guide.
- Presale tracking and advance ticket data. Services like Fandango and Atom track advance ticket sales in real time. A film pacing well ahead of comparable releases at the same point before opening is a strong signal for a higher opening weekend. IMAX and PLF presales are particularly watched for franchise films because those premium formats tend to front-load into the first weekend.
- Studio tracking surveys. Studios commission weekly tracking surveys measuring unaided awareness, definite interest, and first-choice status among different audience demographics. These numbers typically circulate informally in the week before a release and often show up in trade press coverage from outlets like Deadline and The Wrap. When tracking surveys shift, box office contracts shift with them.
- Critical reception and word of mouth. Review embargo lifts and early audience screenings can reprice box office contracts almost as much as tracking data. A film that lands with strong critical reception and early audience enthusiasm tends to outperform its tracking projection. A poorly reviewed tentpole with negative social media sentiment can miss tracking by 20-30%, particularly on franchise sequels where audience enthusiasm may not materialise as expected.
- Competition on the same weekend. A crowded release weekend can suppress any individual film's earnings even when standalone interest is high. When two tentpoles are scheduled for the same weekend, both contracts tend to price lower than they would have in isolation.
- Re-releases and platform expansion. A film already in release that expands its theatre count or goes into premium format re-release can see its cumulative gross contracts reprice as new earnings potential opens up.
How to Start Trading Box Office Prediction Markets
Box office markets follow the release calendar, which means there is almost always a major film opening within a few weeks. Having an account set up before tracking season begins for a major release gives you the best chance to enter at the most informative prices.
- Create and verify your account: Sign up on your chosen site and complete KYC with a government-issued ID. Required before depositing or trading.
- Fund your account: Dollar-based sites accept ACH, debit card, and other standard methods. Polymarket requires USDC via crypto transfer or MoonPay card purchase.
- Find the box office section: Navigate to Culture, then Movies or Box Office. Active opening weekend contracts and annual grossing markets are listed with their current bracket pricing.
- Read the full bracket set: For opening weekend contracts, check all active revenue brackets for the same film. The full set tells you where the market concentrates its probability and which brackets represent the most uncertainty.
- Check the resolution source: Confirm whether the contract uses the 3-day or 4-day figure and which data sources (The Numbers, Box Office Mojo) are required to confirm before the market resolves.
- Choose Yes or No and set your size: Market orders fill immediately. Limit orders let you set your target price. Box office contracts see the heaviest repricing in the 48 hours before and after opening night.
Tips for Trading Box Office Prediction Markets
Box office trading rewards traders who follow the film industry's information cycle closely. A few habits make a real difference.
Follow the trade press tracking cycle
Deadline Hollywood, The Wrap, and Variety all publish box office tracking updates in the week before a major release. These reports carry early tracking estimates and analyst commentary that move contract prices. Reading these sources before the general public does gives you an informational edge on where opening weekend brackets are likely to settle.
Watch IMAX and PLF presales for franchise films
For major franchise releases, IMAX and premium large format presale comparisons to previous comparable films (how does this film's IMAX presale compare to the same point before a similar franchise entry?) are among the most predictive signals available before general tracking arrives. Films that significantly outpace comparable presales tend to beat tracking projections; those that trail tend to miss.
Separate opening weekend views from legs views
A film with a great opening does not necessarily have great legs, and vice versa. Opening weekend contracts and cumulative gross contracts require different analysis. Franchise sequels and action films tend to front-load; slower-burn dramas and word-of-mouth films can build over weeks. Match your contract type to your actual view.
Check liquidity on smaller films
Major tentpole opening weekend contracts carry deep liquidity and tight spreads. Contracts on mid-budget or platform-release films can be thin. A large market order on a smaller film's contract can move the price against you. For more on how liquidity affects execution, see our guide on what slippage means in prediction markets.
The Bottom Line on Box Office Prediction Markets
Box office prediction markets are a well-structured category with clear settlement methodology, a regular release calendar, and a rich information flow from tracking surveys, presale data, and early screening reception. Polymarket leads on market depth and variety, with Kalshi providing accessible dollar-native coverage of major releases. The bracket format for opening weekend contracts makes it easy to find the right position regardless of whether your view is bullish or cautious on a specific film.

Box Office Prediction Markets FAQ
Which sites offer box office prediction markets?
Polymarket has the deepest coverage with 111 active markets and $14.7M in cumulative volume, including opening weekend brackets and annual grossing contracts. Kalshi carries major film opening weekend and annual contracts within its culture category. Crypto.com covers selected film and entertainment markets.
How do opening weekend box office contracts work?
A film's projected opening weekend domestic gross is divided into revenue brackets. Each bracket is a separate Yes/No contract. You pay between $0.01 and $0.99 and receive $1 if the film's actual opening weekend gross falls in your bracket, $0 if it does not. You can sell at any point before the market resolves.
How are box office contracts settled?
Contracts resolve based on official industry data from The Numbers and Box Office Mojo. For opening weekend contracts, resolution uses the 3-day domestic gross figure (typically including Thursday previews), confirmed by both sources. For annual grossing contracts, resolution waits until year-end rankings are confirmed.
What is the 3-day vs 4-day weekend distinction?
Opening weekends are typically measured over Friday through Sunday (3 days). For holiday weekends, studios sometimes report an estimated 4-day figure that includes Monday. Box office contracts usually specify which figure they use. Always check whether the contract resolves on the 3-day or 4-day number before trading a release that falls on a holiday weekend.
What drives box office contract prices?
The main drivers are advance presale tracking, IMAX and PLF presale pacing against comparable films, studio tracking surveys published in the week before release, critical reception and word of mouth at the embargo lift, and competition from other films releasing on the same weekend.
Can I trade box office contracts before a film has been reviewed?
Yes. Contracts open well before the review embargo lifts, priced on tracking surveys, presale data, and historical comparable analysis. When the embargo drops and reviews arrive, contracts reprice significantly, creating one of the most predictable information-driven repricing events in culture prediction markets.
What is the minimum to start trading box office prediction markets?
Minimum deposits are $10 at Kalshi and Crypto.com. At Polymarket, MoonPay card deposits have a practical minimum of around $20. Individual contracts can cost as little as $0.01.
