Adding Prediction Markets to Your Casino

Slots and table games will always be the core of a casino, but they have a ceiling on engagement. Between spins there's nothing to come back for. Prediction and event markets are the format players are increasingly moving to because they fill that gap: a reason to check in every day, tied to the real world.

If you're building or running a casino, they're one of the cheapest ways to add session time and stickiness, as long as your stack is built for them. This guide covers what they are, how they differ from a sportsbook and the parts operators get wrong: pricing, liquidity, settlement and jurisdiction. It also explains how to choose between building in-house, licensing a platform and launching through a partner.

What prediction markets are

A prediction market lets players trade on the outcome of a real event: will a team win, will a price hit a level, who takes an award. Prices move like odds and reflect the crowd's implied probability. They sit between betting and trading, and they behave differently from slots: players follow them over days, not seconds.

The CFTC regulates event contracts in the United States, where real-money online casino is not legal nationwide and is legal only in the few states that have legalised it. It notes that the products traded on prediction markets are frequently called event contracts and that they've existed in regulated markets for more than two decades.

Reading a price as a probability

The CFTC uses this example: a $1 “Will it rain tomorrow?” contract where “yes” trades at 70 cents and “no” at 30 cents. The price reflects the market's expectation, so it puts the chance of rain at roughly 70%. If you buy “yes” at 70 cents and it rains, you earn a 30-cent profit when the contract settles. Traders who predicted wrongly lose their investment, and taxes and fees may also affect returns. Before settlement, either side can trade out at the current price.

Not every market is a simple yes/no. Some combine several yes/no contracts, offer multiple-choice options or use outcome ranges with partial payouts. The CFTC notes that more complex contracts may attract fewer participants, which means lower liquidity. That matters a lot at casino scale.

For an operator, the rain example also shows why the resolution source has to be named before the market opens. Whose measurement of “rain” counts, and for which location?

How prediction markets differ from sportsbooks and slots

Three structural differences matter: who sets the price, who carries the risk and when a player can get out.

Prices set by the crowd, not the house

CFTC-regulated exchanges don't take a side of the trade. They provide a platform for trading and aren't competing against the customer. In most cases, order books show real-time customer bid and ask prices. A fixed-odds sportsbook, by contrast, sets and banks every price itself, and slots carry a built-in house edge.

That doesn't mean markets carry no exposure for you as the operator. If you or a partner seed liquidity or run a market maker, you take on some market risk.

Exiting before the event resolves

Customers can trade in and out of a position at the current market price before settlement, to lock in gains or limit losses. A standard fixed-odds bet usually stays open until the event resolves unless the bookmaker offers cash-out. Being able to trade a position is a big part of why players keep checking back.

Side-by-side: markets, sportsbook, slots

Why they belong in a casino

• High session time. An event that resolves on Sunday gives a player a reason to return all week, which a slot session can't do.
• A different, sticky audience. Markets attract players who like the real-world, skill-adjacent angle, which widens the range of players you can retain.
• Same wallet, more value. Because markets share the casino's wallet, they lift the value of the players you already have, with no new acquisition required.
• An established format, not a fad. Event contracts have traded in CFTC-regulated markets for more than two decades. The CFTC also notes that forecasts from prediction markets are increasingly cited by the media, market analysts, economists and pollsters.

The point of prediction markets isn't to replace slots. It's to give players a reason to open the app on days they otherwise wouldn't. Retention, not replacement.

What's actually hard (and what isn't)

The interface is the easy part. The hard parts are the ones players never see:

1. 01Pricing: setting and moving fair prices as events develop.
2. 02Liquidity: making sure there's always a market to trade against.
3. 03Settlement: resolving outcomes correctly and paying out cleanly.

Building these from scratch is a serious project. Through a partner that already runs pricing, liquidity and settlement, markets become a module you plug into your existing stack and brand, wired into the same wallet and tracking.

Pricing: order books, market makers and hybrids

• Order book (exchange matching). Bids and asks are matched between players. This is the most transparent model, but it needs enough traders on both sides. On a casino-sized audience, thin books mean wide spreads and orders that never fill.
• Automated market maker (AMM). A formula always quotes a price, so a player can always trade. The trade-off is that someone pays for that always-on price through a subsidy, and whoever funds it carries the exposure.
• Hybrid. A market maker seeds the book with quotes until enough real players arrive, then steps back. For most casinos this is the practical middle ground.

Liquidity: solving the cold-start problem

A new market with an empty book gives players no price to trade at, so they leave, and the book stays empty. To break that loop, seed markets at launch, give market makers incentives through fee rebates or tighter spread targets, and accept that the subsidy is a house-risk line in your P&L. A few deep markets beat many empty ones. Keep contract designs simple, because complex structures draw fewer participants.

Settlement, resolution rules and disputes

Choose the resolution source before the market opens and write rules that can't be read two ways. The CFTC says customers are entitled to timely, transparent information about contract terms, including the payout, prices, how settlement determinations will be made, who decides and how. Treat that as your baseline.

Plan for edge cases in writing: postponed events, voided outcomes, disputed results and late data corrections. Publish a dispute policy players can find.

There are two resolution models. Centralised resolution means the operator or partner settles against the named source. Oracle-based resolution is used by some on-chain markets. UMA, for example, describes itself as an optimistic oracle and dispute arbitration system. Its OOv2 lets third-party proposers answer data requests and lists prediction markets as a primary use case. UMA token holders vote on disputes. For most casino operators, centralised resolution with a visible dispute process is the simpler choice.

Regulation and jurisdiction: a checklist, not legal advice

This section is a checklist to work through with your regulator or counsel. It is not a ruling on whether markets are legal anywhere.

CFTC rules on event contracts

In the United States, real-money online casino is not legal nationwide and is legal only in the few states that have legalised it, so this section is not casino-acquisition advice for any US state. Treat each state separately and check with its regulator. At the federal level, designated contract markets (DCMs) operate under CFTC oversight under Section 5 of the Commodity Exchange Act. To get and keep their designation, they must comply with twenty-three Core Principles and the Part 38 regulations.

The Act's special rule for event contracts lets the CFTC determine that certain event contracts are contrary to the public interest. Under 17 CFR 40.11, a registered entity may not list or clear contracts based on an excluded commodity that involve, relate to or reference terrorism, assassination, war, gaming or activity that is unlawful under state or federal law. The CFTC can subject a contract to a 90-day review and request that its listing or trading be suspended during that review.

Great Britain and other licensed markets

In Great Britain, the Gambling Commission sets out the licence types you may need, what they cost, and the licence conditions and codes of practice that apply, including anti-money-laundering guidance. Before you launch, ask your regulator whether event markets are covered by your existing gambling licence, and don't assume they are. For background, see casino licensing explained.

Ontario is a good example of supplier scope. Operators must take steps with both iGaming Ontario and the AGCO, and some suppliers need AGCO registration and technology certified by a registered independent testing laboratory. Your markets supplier is part of your compliance scope.

Your pre-launch licence checklist

• Does your licence explicitly cover event or betting products?
• Are any categories, such as elections, restricted where you operate?
• Does your markets supplier need registration or certification?
• Do your terms and conditions, and your responsible gambling disclosures, cover markets?

Choosing which markets to list

The main categories are sports-adjacent events, entertainment and awards, crypto and asset prices, and everyday events such as weather. The CFTC's “Will it rain tomorrow?” example shows how simple a good contract can be.

Match categories to your players and to the licensed markets you operate in. A sports-heavy base suits sports-adjacent markets, while a crypto-native or Telegram audience suits price markets. Avoid or restrict politically sensitive markets, markets where a small group could know or influence the outcome, and anything in the categories regulators single out. Start with a small number of recurring, easy-to-resolve markets that have a clear official source.

Integrity and responsible gambling

• Insider and manipulation risk. Regulated exchanges must establish and enforce rules and monitor trading for abuses such as market manipulation and insider trading. Apply the same thinking: watch for unusual positions and exclude people with inside access.
• Position limits per market and per player, especially on thin markets that are easy to move.
• One wallet, one KYC/AML process, so markets don't become a gap in your AML controls.
• Existing RG tools should apply to markets as well: deposit limits, self-exclusion, reality checks, and clear disclosure of risks and fees. The CFTC's advice to trade only with risk capital is a useful model for player messaging.

How to add them

• If you're launching a new casino: design for markets from the start, with one wallet, one back office and the markets alongside the lobby. Adding them later is possible but takes more work. See the complete guide to starting an online casino.
• If you already operate: the fastest path is a partner that launches prediction and event markets under your brand and handles pricing, liquidity and settlement for you.

Build, white-label or full-stack partner

Launch checklist for existing operators

1. 01Confirm your licence position.
2. 02Pick the integration path.
3. 03Connect a single wallet and login.
4. 04Configure market categories, position limits and RG tools.
5. 05Write and publish resolution rules and a dispute policy.
6. 06Soft-launch with a few deep markets.
7. 07Promote markets from the casino lobby, and the casino from the markets.
8. 08Measure.

What to measure after launch

These are metrics to track, not promised results.

• Return frequency: DAU/WAU and days between sessions, comparing players who use markets with those who don't.
• Cross-play: the share of market players who also play casino games, and the reverse.
• Market health: spread and depth per market, and how often markets go untraded.
• Settlement quality: disputes, voided markets and time to settle.
• Lifetime value: LTV for players who use markets compared with your existing cohorts, tracked over time.

Common mistakes

• Launching too many illiquid markets instead of a few deep ones.
• Vague resolution rules, or no published resolution source.
• A separate wallet or login for markets.
• Treating markets as a bolt-on with no lobby placement or cross-promotion.
• Assuming one jurisdiction's rules apply everywhere.
• No plan for postponed or voided events.

FAQ

What are prediction markets?

Markets where players trade on the outcome of real-world events, such as sports, politics and entertainment, with prices that move like odds. They sit between betting and trading, and they hold player attention between casino sessions.

Why add prediction markets to a casino?

They add high session time and a reason to return that pure slots do not. They attract a slightly different, sticky audience, and they share the same wallet, so they lift the value of players you already have.

Are prediction markets hard to launch?

The hard parts are pricing, liquidity and settlement. Through a partner that handles those, adding markets to an existing stack is straightforward and much easier than building them from scratch.

Are prediction markets legal for my casino?

It depends on your jurisdiction and licence, so confirm with your regulator or counsel. In the US, where real-money online casino is not legal nationwide and is legal only in the few states that have legalised it, event contracts fall under the CFTC. Its rules bar registered entities from listing or clearing contracts based on certain excluded commodities that involve terrorism, assassination, war, gaming or unlawful activity. In Great Britain and other licensed markets, ask your regulator whether event markets are covered by your existing gambling licence. Also check whether categories such as elections are restricted.

How do prediction markets make money for the operator?

Typically through trading fees or the spread rather than a house edge. On regulated exchanges, the platform does not take a side of the trade and is not competing against the player. If you or a partner seed liquidity or run a market maker, that activity can bring in revenue but also carries market risk, so build both into your model.

Do I need my own liquidity to run prediction markets?

Someone has to provide it, at least at the start, because an empty order book leaves players with no price to trade at. The options are a market maker that seeds the book, an automated market maker that always quotes a price, or a partner that supplies liquidity. Launching with a few deep markets reduces how much you need.

How long does it take to add prediction markets to a casino?

It depends on the route. Building from scratch is the slowest. A white-label platform is faster but still needs wallet and back-office integration. A full-stack partner already wired into your stack is usually the quickest. Whichever route you take, licence checks can add time, and so can supplier registration and testing-lab certification in markets such as Ontario.
