Market context
The ITF Women’s match in Sao Paulo between Giovana Schincariol Delatorre Barbosa and Marjorie Souza, originally set for 14 July 2026, has not been played, leaving the Polymarket contract for Barbosa’s advancement at a 0% YES price. On Polygon, this conditional token trades in USDC with no liquidity, reflecting the market’s view that the event is either abandoned or indefinitely delayed beyond the seven-day settlement window.
Historically, ITF matches postponed by more than seven days without a result resolve as “no winner” on prediction platforms, voiding all positions. Comparable cases from 2024–2025 ITF tournaments in South America show similar 0% pricing when weather or player illness cancels fixtures before play begins, with traders exiting immediately once the delay exceeds the settlement threshold.
Traders should monitor the ITF Sao Paulo official schedule and local Brazilian tennis federation announcements for any rescheduling notice. A recent update from the ITF website confirms no replacement match has been scheduled as of 14 July, and the tournament director has not issued a formal cancellation statement [1]. Without a confirmed replay date before 21 July 2026, the contract will likely settle as void, rendering the current 0% price accurate.
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.
