Ilkley: Billy Harris vs Clement Chidekh

Platform comparison

Active sub-markets

Market context

Billy Harris and Clement Chidekh are scheduled to meet at the Ilkley tournament on 8 June 2026. The match carries a settlement window extending to 15 June 2026 at 09:00 UTC, allowing a seven-day buffer for rescheduling or completion. Under the market's terms, cancellation, ties, or delays exceeding that window trigger a 50-50 resolution; if play begins but one player retires, the advancing player wins the market outright. The current 100% implied probability for Harris suggests either exceptionally high confidence in his victory or minimal liquidity at present, a state common in early-stage tennis markets where information asymmetry favours informed traders.

Comparable ATP Challenger and ITF matches at grass-court venues show that seeding disparities and surface familiarity typically drive pre-match probabilities. Harris, a British player, holds home advantage at Ilkley, a factor historically weighted at 3–5 percentage points in grass-court prediction markets. Chidekh's recent form, ranking trajectory, and head-to-head record (if any) remain the primary catalysts for probability recalibration. Traders should monitor ATP and ITF official draw confirmations, injury announcements, and withdrawal notices through the ATP website and tournament organisers' channels in the week preceding the match.

From a regulatory standpoint, this market operates under German GlüStV provisions where applicable and falls within CFTC oversight for US-based traders. The no-KYC threshold of $1,500 USD permits retail participation without identity verification up to that stake level, though position limits and reporting obligations may apply above it depending on jurisdiction. Polymarket-legal.co.uk users should verify their local regulatory status before trading.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, Polymarket Legal UK triggers a quick verification flow that finishes in minutes.

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.
