Estoril Open: Alejandro Tabilo vs Tiago Torres

Platform comparison

Market context

Alejandro Tabilo’s meeting with Tiago Torres at the Estoril Open is the underlying event here, and the market will pay out based on which player *advances* rather than simply who is favoured on paper. In prediction-market terms, a **YES** share pays if the named outcome happens and a **NO** share pays if it does not; with this contract, the key question is whether Tabilo progresses against Torres before the settlement deadline. Pre-match tennis pricing points strongly towards Tabilo, with one live tournament listing giving him an 87% projected win rate and other previews also picking him in straight sets.[1][2]

The current crowd-implied probability of **0% YES** suggests the market is effectively treating a Tabilo advance as extremely unlikely or already priced out, but that should be read carefully. In tennis markets, the last stretch before settlement can be shaped by late withdrawals, walkovers, or a match that starts but is not completed, and comparable venue listings show the fixture still sitting at 0–0 in set terms before play.[3][4] If the match is not completed, or is cancelled or delayed beyond seven days without a winner, this contract resolves to 50-50 rather than to either player.[4]

What traders should watch most closely is the official match status: start time changes, withdrawal notices, and whether the contest is completed in full. The market text makes clear that an automatic advance, cancellation, or prolonged delay can all override the straightforward win/loss outcome, so the practical catalyst is not only the scoreline but also whether the ATP and tournament feeds confirm a completed result within the allowed window.[4]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market UK, which mirrors the Polymarket order book directly.

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.
