Istanbul 2: Akira Santillan vs Antoine Ghibaudo

Platform comparison

Market context

Akira Santillan and Antoine Ghibaudo are into an Istanbul Challenger meeting that, on the live data, is already in progress, with Santillan listed around ATP 291 and Ghibaudo around ATP 351. The market’s 0% YES crowd read is therefore best treated as a stale or mispriced input rather than a clean directional view, because any in-play movement, retirement, or completion state can still drive the final settlement logic.

For a programmatic workflow, the useful comparison is not head-to-head — there is no prior match-up recorded in the supplied data — but recent form and surface continuity. Santillan’s 2026 win rate is shown at 57.1% across 42 matches, versus Ghibaudo’s 50.0% across 30, while broader last-12-month records also lean Santillan’s way. Comparable pre-match pricing elsewhere has been close, which fits a lower-tier Challenger match where small changes in server hold, medical time-outs, or weather delays can matter more than ranking gaps.

The key catalysts to monitor are the official score feed, any walkover or retirement flags, and whether the match is completed inside the seven-day settlement window ending 2026-08-12T10:00:00Z. If the fixture is not played at all, ends tied, or is pushed beyond that deadline without a winner, the market resolves 50-50; if it starts but does not finish, the terminal state decides the outcome. For bots, that means polling the tournament draw and live scoring endpoints, then applying a hard settlement override on confirmed abandonment rather than relying on pre-match probability alone.

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 Polymarket Bot 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.
