The core idea

In a binary market, shares typically trade between 0 and 1 (or 0¢–100¢). A price of 0.62 usually means the market implies about a 62% chance the event resolves Yes — after fees and spreads.

How settlement works

Markets resolve against written rules and a resolution source (official results, data feeds, oracles, or platform adjudication). Ambiguous wording is a common source of disputes — always read the market rules before trading.

Liquidity and spreads

Thin markets can move against you. Check depth, recent volume and bid–ask spread before sizing a position. A high “headline” probability means little if you cannot exit.

Custody models

  • Wallet / on-chain: you hold keys; network fees and smart-contract risk apply.
  • Account / regulated: KYC, bank rails, and venue rules apply; clearer for some jurisdictions.
  • Play-money / community: useful for learning; not the same as cash markets.

What to do next

  1. Pick a region-aware shortlist on Regions.
  2. Compare two options in Compare.
  3. Read a platform profile, then use Visit only after checking eligibility.

FAQ

What is a prediction market?

A venue that prices the chance an event happens, usually as Yes/No shares. The price is a signal, not a guarantee.

Is this the same as a sportsbook?

No. Event contracts and sportsbook parlays are different products and usually different licences. See event betting platforms if that is the job.
