Bloomfield Hills: Moez Echargui vs Lloyd Harris

Platform comparison

Market context

Lloyd Harris has already advanced past Moez Echargui in the Bloomfield Hills Challenger, having secured a 2–0 victory on Monday, 20 July 2026, which explains the crowd-implied probability of 0% for Echargui to win this market[5][6]. The match, originally scheduled for 10:00 AM ET on Court 2, concluded with Harris winning both sets 6–6 (likely a typo for 6–4 or 6–3, but confirmed as a 2-set win)[3][5].

Historically, when a match in a prediction market has already been played and a winner determined, the market resolves immediately to that outcome, rendering the YES probability for the loser effectively zero. Comparable cases in tennis prediction markets show that once a result is confirmed across multiple score-tracking platforms, liquidity collapses on the losing side, and no further trading occurs unless a formal cancellation or protest is filed[5][6].

Traders should monitor official ATP or tournament organiser announcements for any post-match appeals or disqualifications, though no such notices have appeared as of Tuesday morning. The settlement window remains open until 27 July 2026, but with Harris confirmed as the winner and no pending delays beyond the seven-day threshold, the market is expected to resolve to “Lloyd Harris” without further catalysts[3][5].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
