Bloomfield Hills: Moez Echargui vs Lloyd Harris

Platform comparison

Market context

The underlying event is a Challenger-level tennis match in Bloomfield Hills between Moez Echargui and Lloyd Harris, originally scheduled for 20 July 2026. The match has already concluded with a 0–2 result in favour of Harris, as confirmed by live score trackers and betting records showing a completed fixture on 20 July at 18:25 local time [2][4]. Despite the market’s crowd-implied probability of 0% YES for Echargui advancing, the real-world outcome is settled: Harris won both sets, meaning the market will resolve to “Lloyd Harris” unless a rare administrative override occurs.

Historically, prediction markets on completed tennis matches that show 0% probability for the losing player align with the actual result when odds heavily favour the winner pre-match. In this case, Harris carried initial odds of 1.30–1.33 across major bookmakers, while Echargui was priced at 2.94–3.14, reflecting a clear expert consensus that Harris would win in two sets [1][3]. Comparable Challenger matches with similar odds spreads have resolved cleanly to the favoured player, with no ties or cancellations affecting the outcome, reinforcing the reliability of the 0% crowd signal here.

Traders should monitor official tournament archives and ATP Challenger result feeds for any post-match appeals or disqualifications, though no such dependencies are currently active. The settlement window ends 27 July 2026, but with the match already completed and Harris advancing, no further catalysts are expected to alter the resolution [4]. For programmatic approaches, conditional orders can be set to close YES positions on Echargui immediately, as the outcome is effectively locked in by the 0–2 scoreline.

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

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.
