Newport: Mananchaya Sawangkaew vs Caroline Dolehide

Platform comparison

Market context

This market tracks the outcome of the WTA 125K Newport Round 1 match between Mananchaya Sawangkaew and Caroline Dolehide, which was played on the grass courts in Newport, USA, on 7 July 2026. The match has already concluded with Sawangkaew winning, as confirmed by live score records showing a victory on 8 July 2026 [1]. The 100% YES crowd-implied probability reflects this settled result, meaning the market will resolve to Mananchaya Sawangkaew as the advancing player.

Historically, prediction markets for completed tennis matches with confirmed winners resolve immediately once official results are logged, and a 100% probability indicates no uncertainty remains. Comparable cases in WTA 125K events show that once a match result is verified by multiple score aggregators, the market settles without delay [2][3]. In this instance, Sawangkaew’s win is recorded across platforms, eliminating any risk of a 50-50 resolution due to cancellation or delay.

Traders should monitor official WTA 125K Newport draw updates and player advancement confirmations to validate the settlement, though the result is already fixed. Recent tournament coverage confirms Sawangkaew advanced past Dolehide in Round 1, with no indication of match postponement beyond the seven-day window [3][4]. For programmatic approaches, conditional orders can be set to execute only if the settlement status changes, but given the confirmed outcome, no further catalysts are expected to alter the resolution.

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.
