Samsun: Kenta Miyoshi vs Constantin Bittoun Kouzmine

Platform comparison

Market context

Polymarket has this contract pricing **0% YES** today, so the on-chain market on Polygon is effectively saying there is no current expectation that the Kenta Miyoshi side will resolve as the winner in USDC-settled conditional tokens. For a trader, that reads less like a view on the abstract matchup and more like a market telling you the contract is either mispriced, stale, or waiting on live event confirmation from Samsun.

The underlying tennis match is listed for the Samsun Challenger semi-finals on an outdoor hard court in Türkiye, with start times across live scoreboards clustering around 08:00 UTC, and the players are closely ranked: Constantin Bittoun Kouzmine is around ATP 507, while Kenta Miyoshi is around ATP 602 in the live listings. Comparable ATP Challenger markets with rank gaps of this size often trade as one-sided only when the favourite is clearly signposted by bookmaker odds or match-state data; here, external odds shown by Sportsbet have Miyoshi at 1.13 and Bittoun Kouzmine at 4.90, which is sharply at odds with a 0% YES on the Kenta side and suggests the Polymarket price may be detached from the live tennis context.

The main catalysts are straightforward: official confirmation that the match starts, any delay from the Samsun order of play, and whether the scoreboards continue to show active play rather than a cancellation or retirement. Because the market settles to 50-50 if the match is not played, ends level, or is delayed beyond seven days without a winner, the key risk is not just who advances but whether the fixture completes inside the settlement window ending 2026-08-08T08:00:00Z. On-chain, that means the decisive input is not the pre-match narrative but the eventual tournament result that maps into the conditional token outcome.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
