Choosing a prediction market exchange is about more than finding the platform with the greatest number of markets. Fees, liquidity, contract rules, payment options, account requirements and regional availability can all affect the experience—and ultimately determine whether a platform is suitable for you.
Prediction Buzz independently reviews prediction market exchanges, event contract platforms and Web3 forecasting protocols. Our reviews examine how each platform works, what it costs to use and the protections and limitations users should understand before committing funds.
Whether you are comparing regulated US exchanges, exploring cryptocurrency-based prediction markets or researching how different platforms settle their contracts, this hub brings our exchange reviews and comparisons together in one place.
The global prediction landscape is split across distinct regulatory and operational structures. Before committing trading capital, analyze the core differences in legal status, fee models, funding mechanisms, and regional availability across the world’s leading event contract matching engines:

Prediction market exchanges allow participants to take positions on clearly defined future outcomes. Many markets use binary contracts that settle according to whether an event occurs. A contract may be priced between $0 and $1, with its price often interpreted as the market’s approximate probability of the outcome.
Probability Calculation Example: A “Yes” contract trading at $0.65 could be interpreted as indicating an estimated 65% probability. If the defined event occurs and the contract settles at $1, a purchaser who paid $0.65 would receive the difference ($0.35). If the event does not occur, that contract settles at zero.
This is a simplified illustration. Actual prices, fees, order execution and settlement procedures depend entirely on the individual exchange and specific contract rules. The exact wording of the market rules is crucial. A market’s headline may provide a convenient summary, but the settlement criteria determine precisely what must happen, which primary source will be used, and when the outcome will be decided.
Regulated exchanges operate within a defined legal and supervisory framework. In the United States, these platforms register as Designated Contract Markets (DCMs) under the oversight of the Commodity Futures Trading Commission (CFTC). They require strict identity verification, restrict participation by jurisdiction, and provide contracts subject to formal regulatory settlement rules.
Note: Regulatory status should not be interpreted as a guarantee against losses. Users must still calculate pricing, liquidity, fees, and the possibility of an incorrect prediction.
Web3 prediction markets use blockchain networks, smart contracts, and digital stablecoins to facilitate peer-to-peer trading and automated settlement. These decentralized platforms introduce distinct tracking considerations:
Compliance Reminder: A platform being decentralized does not remove a user’s obligation to comply with the local financial laws that apply in their specific country or state.
Betting exchanges allow customers to trade positions for or against sporting and other outcomes, with prices generated directly by market participants rather than a conventional sportsbook bookmaker. Although betting exchanges and prediction markets share certain features, they differ substantially in their legal classification, contract asset structures, financial terminology, fee templates, and formal settlement processes.

Prediction Buzz uses a consistent methodology so readers can compare platforms objectively. In accordance with Chin Ho's operational standards, our reviews track the complete user journey rather than relying on marketing data supplied by the platforms:
Regulated prediction exchanges (such as Kalshi and Novig) operate inside a formal legal framework in the United States under the direct oversight of the Commodity Futures Trading Commission (CFTC). They process trades in US Dollars, require strict identity verification (KYC), and ensure capital is cleared securely.
Decentralized protocols (such as Polymarket) operate on public blockchain ledgers (like Polygon). They utilize Web3 smart contracts to match orders and clear trades automatically using crypto stablecoins (USDC). These platforms operate globally but are strictly geoblocked for United States residents due to domestic regulatory restrictions.
Fee templates vary drastically across the industry:
Yes, but exclusively on federally designated platforms. US residents can legally trade event contracts on platforms registered as a Designated Contract Market (DCM), such as Kalshi and Novig. Conversely, decentralized Web3 prediction networks heavily enforce geofencing protocols to block US IP addresses from accessing their order books to comply with CFTC enforcement mandates.
Every prediction market is governed by a strict, pre-defined set of settlement criteria. When a contract expires, the exchange evaluates the outcome using an authoritative, neutral primary data source (such as a government economic release, official judicial filing, or major athletic box score).
On Web3 protocols, this data is routed via decentralized settlement networks (oracles) like UMA, where community token-holders vote to confirm the factual real-world outcome if an asset resolution is formally disputed.
The legal classification depends entirely on the jurisdiction and platform structure:
