| If you want… | Start with… | Why | Check first |
|---|---|---|---|
| Broad crypto-native event discovery | Polymarket | Wallet-native outcome-share markets and broad categories | Eligibility, rules, UMA resolution, depth, wallet route |
| Account-based event contracts | Kalshi | Market-specific rules and official-source settlement process | KYC, jurisdiction, limits, fees, determination time |
| Hyperliquid-native event-market research | HIP-4 | A market-structure direction to monitor | Whether the exact market is deployed, liquid, and documented |
A prediction market is a market for contracts that pay according to a defined event outcome. The price can resemble an implied probability, but it is still a tradable price affected by wording, liquidity, fees, time, and trader incentives. The contract rules—not the headline—determine settlement.
Read the exact question, event window, cutoff, source, edge cases, and dispute path. Polymarket documents an UMA optimistic-oracle process. Kalshi identifies a verification source and determination criteria in its market rules. Those are different operational models.
Check spread, order-book depth, maximum order size, recent trades, and whether you can exit before settlement. Headline volume is not the fill you receive.
Confirm region, KYC, wallet or account requirements, deposit asset, withdrawal route, and settlement currency. A market is not a usable opportunity if the product is unavailable to you.
Politics, sports, macro, conflict, and culture markets can attract informed participants, coordinated narratives, and attempts to influence the event. A high probability is not a guarantee and a liquid market is not necessarily a calibrated forecast.

Use Polymarket for broad crypto-native discovery, Kalshi for an eligible user who prefers account-based event contracts, and HIP-4 as a deployment-specific research question. Do not compare prediction markets by probability screenshots alone; compare the contract and settlement system underneath.
