Market context
Dota 2: Team Spirit vs Aurora (BO3) - DreamLeague Playoffs. The market is currently pricing the outcome at 100% YES, meaning crowd-implied probability sits at that level. Settlement is scheduled for 2026-05-24T17:00:00Z. Unlike a sportsbook, the price you see is set by buyers and sellers competing in a live order book — there is no house edge or bookmaker margin to fade.
World-affairs prediction markets price discrete geopolitical outcomes — ceasefires, treaty signings, leadership transitions — and tend to drift on rumour and snap-correct on official announcements.
Watch for the underlying catalysts that move this category: each official announcement, dataset release, or scheduled milestone generally produces a step change in the implied probability. Trades execute instantly on Polygon, and shares pay $1 each at resolution if your side wins.
Methodology
Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — are listed with their platform attributes, because they operate off-chain and a 1:1 comparison of contract mechanics isn't possible.
Resolution & payout
Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.
Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

- On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- How does resolution work?
- Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
