Market context
What will Kevin Warsh say during July Press Conference?. The market is currently pricing the outcome at 0% YES, meaning crowd-implied probability sits at that level. Settlement is scheduled for 2026-07-29T23:59:00Z. 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
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market UK, which mirrors the Polymarket order book directly.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
FAQ
- 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.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- What does Polymarket cost to trade?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Market UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
