Understanding Prediction Markets: What They Are and Why They’re Important for iGaming

Prediction markets allow people to back their opinions with cash, betting on how events will play out. Contracts usually wrap up with a result, like Yes or No, and their price shows what the market thinks about how likely that result is to happen. The category grew swiftly in 2025. By the end of that year, the activity on prediction-market websites hit over $44 billion. Polymarket and Kalshi have really carved out their niche, as sportsbooks begin to check out prediction-based products.

Key Takeaways:

• In prediction markets, most trading occurs directly between users, while betting on events usually relies on odds;
• Contracts typically trade anywhere from $0 to $1, paying out $1 if the chosen result happens;
• Prices in peer-to-peer markets are set by users, not dictated by the website;
• Traders can offload their contracts before the settlement instead of just waiting for the outcome;
• Laws differ by region and may label prediction markets as either derivatives, gambling, or something in between;
• For iGaming firms, prediction markets might spark a new kind of event-based betting that goes beyond sports.

What Are Prediction Markets?

A prediction market lets participants bet on the outcomes of events like elections, economic changes, sports results, or cultural events. Most markets focus on questions such as: ‘Will Country X enter a recession this year?’

Participants purchase contracts that represent potential outcomes. Prices go up and down as folks buy and sell, creating a perspective on the chances that shifts. There are usually two main types.

How Prediction Markets Work

In a usual peer-to-peer market, users trade contracts with each other directly.

A Yes contract priced at $0.65 suggests there’s about a 65% chance in the market. If the event happens, the contract is worth $1. If it doesn’t, it’s worth nothing. A trader who buys in at $0.65 stands to gain $0.35 for each contract if the market goes Yes. Prices fluctuate as the forces of supply and demand evolve. If insights boost assurance in the result, the contract could leap from $0.65 to $0.80.

The trader doesn’t need to hang around for the settlement. They can move the contract for $0.80 and take advantage of the price gap.

Who Creates Prediction Markets?

Typically, businesses put together groups that outline the markets, establish resolution standards, and choose the data source that will decide the outcome. Users can brainstorm ideas for markets, but usually, those proposals need approval before trading kicks off.

Thriving markets often require:

• Clear results;
• Trustworthy sources for conclusions;
• Minimal risk of manipulation;
• Acceptable guidelines.

How Prediction-Market Sites Generate Revenue

P2P websites typically make money from transaction fees instead of relying on a sportsbook’s margin. Depending on the site, you might run into some charges for:

• Trading;
• Payouts;
• Setting up markets;
• Other services.

Having liquidity really matters. A P2P prediction market requires multiple buyers and sellers, so users can enter or exit their positions without emptying their wallets.

Prediction Markets vs Sports Betting

Although both prediction markets and sportsbooks center on placing bets concerning future events, they operate in distinct manners. A sportsbook determines the odds and takes bets on what it provides. A P2P prediction site acts like a spot for traders to connect.

You’ll certainly notice the change as you finish up. In a prediction market, a trader can sell for the going price. In a sportsbook, the company decides how much cash-out money you can take.

P2P vs Fixed-Odds Prediction Markets

Prediction markets rely on trading among individuals, yet businesses in the iGaming sector can also provide event predictions using a fixed-odds system. In this setup, the player is placing bets straight against the company. Odds are influenced by probabilities, exposure, and market data, and they’re set when you place a bet.

Prediction-Market Regulation by Region

By 2026, regulations will vary by region, each with its own nuances to consider.

United States

In the US, prediction markets are mostly viewed as financial products.

Europe

United Kingdom

Since prediction markets are viewed as betting products, they need to be authorized by the UK Gambling Commission.

Elsewhere

The source points out various restrictions or bans impacting operations in places like Australia, New Zealand, Brazil, Argentina, and several countries in Europe and Asia. Companies really ought to check the status of prediction markets from one country to another, instead of just thinking that one license will be enough for all of them.

Running a P2P exchange can be challenging for a sportsbook, but fixed-odds event betting sidesteps a lot of those issues.

This allows projects to tap into prediction markets without having to overhaul their system like a trading exchange would.

---

What Makes a Good Prediction Market?

It’s essential to have clear rules for resolution, as each contract needs to wrap up with a clear-cut answer. Resolution rules that aren’t properly planned can lead to arguments, even when the trading technology is running just fine. Before rolling out a market, the company should sort out:

• The main question;
• When to wrap up;
• The date for resolution;
• A reliable data source;
• The criteria for a Yes or No;
• The rules for cancellations or uncertain results.

• How products get sorted;
• Understanding the market;
• Worries about manipulation;
• Picking events;
• Staying compliant;
• Liquidity for peer-to-peer products;
• Tech integration;
• Controls for responsible betting.

---

To Wrap It Up

For iGaming companies, expanding options is essential: prediction markets can touch on various subjects, including politics, economics, entertainment, technology, sports, and events all year long.

However, the tough part is figuring out the regulations. There’s still no solid guideline, so businesses have to figure out how prediction markets get classified and approved in each area they plan to work in.
