Market context
Quebec City: Jesper de Jong vs Hugo Gaston. The market is currently pricing the outcome at 0% YES, meaning crowd-implied probability sits at that level. Settlement is scheduled for 2026-08-28T16:30:00Z. 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 compares Quebec City: Jesper de Jong vs Hugo Gaston specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets.

Every CTA routes to Kalshi Alternative UK, which mirrors the Polymarket order book at 0% fees.
Resolution & payout
Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.
Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
UK Frequently Asked Questions
- Which platform has the deepest liquidity?
- Polymarket — by a wide margin. Top markets reach $50-500M volume, Kalshi ~$200M cumulative, Betfair similar. Deeper liquidity means your trade moves the quote less.
- Is Betfair a Polymarket alternative?
- Only partially. Betfair Exchange is UK-focused with a sports-betting emphasis; they have politics markets but with thinner liquidity than Polymarket. Settlement in GBP/EUR, 2-5% commission on winnings.
- What about Smarkets as an alternative?
- Smarkets is a UK betting exchange with a lower default commission (2%) than Betfair. Liquidity on political markets is below Polymarket, comparable to Kalshi. Geo-blocked in many jurisdictions.
- Polymarket vs Betfair Exchange: which is better for UK prediction trading?
- Betfair Exchange offers UKGC regulation, GBP settlement, and potentially tax-free winnings — but focuses on sports and politics only. Polymarket has deeper liquidity, 0% platform fee, global event coverage, and crypto/geopolitical markets Betfair doesn't offer. For UK traders: Betfair for regulated GBP sports markets; Polymarket for broader, global prediction events.
- Is Kalshi available in the UK?
- Kalshi is a US CFTC-regulated prediction exchange. UK residents can create accounts but must use USD and US payment methods. Kalshi's product range overlaps with Polymarket but with lower liquidity on most contracts. For UK traders, Polymarket typically offers better prices due to higher global volume.
