ITF Sao Paulo: Giovana Schincariol Delatorre Barbosa vs Marjorie Souza

Platform comparison

Market context

The underlying event is a scheduled ITF Women’s singles match in Sao Paulo between Giovana Schincariol Delatorre Barbosa and Marjorie Souza, originally set for 14 July 2026 at 5:30 PM ET. With the settlement window closing on 21 July 2026 and the crowd-implied probability for Barbosa advancing at 0% YES, the market currently treats her victory as effectively impossible, suggesting either a known withdrawal, injury, or administrative cancellation before play commenced.

Historically, ITF-level markets showing 0% implied probability for a named player typically resolve to the opponent only when one participant is absent at the scheduled time, as seen in multiple 2024–2025 ITF South America events where matches were declared “no contest” due to player unavailability, triggering automatic resolution to the registered opponent. In such cases, conditional-order bots on prediction platforms automatically flip positions once official tournament feeds confirm the absence, bypassing manual intervention.

Traders should monitor the official ITF Sao Paulo tournament schedule and live match logs for status updates labelled “cancelled,” “withdrawn,” or “no contest,” as these are the primary catalysts that would invalidate the 0% pricing. The ITF’s daily tournament bulletin, published each morning on its official site, is the authoritative source for such changes and should be fed into any automated trading script via its JSON endpoint to capture resolution triggers before the market closes.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
