ITF Landisville: Hanna Chang vs Elizabeth Mandlik

Platform comparison

Market context

The underlying event is a first-round ITF Women Landisville match between **Hanna Chang** and **Elizabeth Mandlik**, but the market is already signalling heavy confidence that Mandlik progresses. The prediction contract is priced at **0% YES**, while sportsbook reference pricing is materially less extreme: Sportsbet lists Mandlik at **1.42** and Chang at **2.65**, which implies a clear favourite but not a shut-out.[8][12] Live-score and tennis aggregation pages also show Mandlik ahead in the match listing, and both players are on the current Landisville card, which matters because a completed match is the cleanest route away from the market’s 50-50 fallback.[1][3][4]

Historical and comparable data support Mandlik’s edge, but they also explain why a 0% prediction-market line can be too absolute for an ITF contract. Mandlik leads the head-to-head **1-0**, with that meeting coming at Landisville in 2022, and ranking snapshots put her ahead of Chang at roughly **WTA 178** to **WTA 295**.[2][5] Season records in the comparison feeds also lean Mandlik’s way, while Chang’s results have been more mixed over recent seasons.[2][11][15] In comparable lower-tier ITF matches, market prices often compress around a strong favourite when the ranking gap and prior head-to-head point in the same direction, yet that still leaves some residual uncertainty about a retirement, walkover, or administrative delay.

For traders, the main catalysts are not broader tour news but match-state and scheduling updates: whether the fixture has actually been played, whether it finishes within the seven-day settlement window, and whether either player withdraws before completion. The match was originally set for **5 August 2026 at 11:00 ET**, and the settlement window runs to **12 August 2026 at 15:00 UTC**, so any postponement beyond that deadline pushes the contract towards the tie outcome under the rules.[3][4][6] The practical watchlist is the official ITF draw/order-of-play, live scoring, and any withdrawal or retirement notices, because those are the events most likely to move this market away from a straightforward Mandlik win or into the contract’s 50-50 fallback.[3][6][7]

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.

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.
