ITF Bali: Sanhui Shin vs Alexander Chang

Platform comparison

Market context

Sanhui Shin is due to face Alexander Chang in the ITF Bali men’s event, and the market is currently pricing that outcome at **0% YES**, which is a clear disconnect from the only available match-level pricing signal. A public preview page for the fixture lists Shin at odds of **1.24**, implying an expected win chance of **74.64%**, so a programmatic trader would treat the current market as an outlier rather than a neutral read-through of the fixture[1].

For comparable ITF-level matches, the useful frame is operational rather than headline-driven: check whether the match is still on the day schedule, whether a walkover or withdrawal has been posted by the event feed, and whether either player appears in adjacent draw updates. In small ITF events, late substitutions and venue timing changes are common enough that a 0% quote can persist until a confirmed start list or live score update forces repricing, so automated tooling should watch the official order of play and draw/status endpoints rather than rely on one preview page alone[1].

The key catalysts are simple: final court allocation, any withdrawal notice before the scheduled start, and whether the match actually begins within the settlement window. If the fixture is postponed beyond seven days without a winner, or never played, the market can flip to its fallback 50-50 settlement, so bots and conditional orders should be keyed to official status changes rather than implied win probability alone[1]

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 Review 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.

How does resolution work?

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
