ITF Tianjin: Ku Keon Kang vs Toshiki Karigyo

Platform comparison

Market context

Ku Keon Kang’s match with Toshiki Karigyo in the Tianjin ITF Men’s event is the underlying tennis result here: a **YES** share pays out if Kang advances, while a **NO** share pays out if Karigyo advances. The current crowd-implied probability of 0% YES suggests the market is pricing Kang as an extremely unlikely winner, although prediction markets can move sharply if live scoring, a walkover, or a withdrawal changes the outlook.

The main reason to read that figure cautiously is that tennis prediction markets often reflect a mix of pre-match form and in-play information, and this contest has limited historical head-to-head evidence. Available match-tracking sources list no prior head-to-head meetings, while current form indicators have varied between the two players, with one source showing Karigyo stronger over the last 12 months on hard courts and another live pricing feed implying Karigyo as the clear favourite during the match.[1][14] For a newcomer, that means a low YES price is not a statement about the broader tour, but a snapshot of how this single fixture is being valued.

The key catalysts are straightforward: whether the match is actually played, whether it starts on time, and whether either player retires or withdraws before a winner is decided. The market rules say a cancellation, tie, or delay beyond seven days without a winner would settle 50-50, which is important because ITF schedules can shift late in the day.[17] Live scoreboards and betting feeds already show the fixture as in progress or recently completed, so traders should watch official match status, score updates, and any retirement notice rather than relying only on the scheduled start time.[3][5][15]

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.
