ITF Taipei: Kayo Nishimura vs Yu Ning Tsai

Platform comparison

Active sub-markets

Market context

The underlying real-world event is the W35 Taipei women’s tennis match between Kayo Nishimura and Yu-Ning Tsai, scheduled for 23 June 2026 at 12:15 AM ET. In prediction markets, a YES share pays out if the market resolves to the named outcome—here, that Kayo Nishimura advances—while a NO share pays if Yu-Ning Tsai advances or the match is cancelled. With the crowd-implied probability at 100% YES, the market treats Nishimura’s victory as virtually certain, a stance that mirrors historical patterns in lower-tier ITF events where one player dominates a recent head-to-head or form curve.

Comparable cases from recent W35 tournaments show that when a player has won their last match decisively—such as Yu-Ning Tsai’s 6–1, 6–2 win over Dayeon Back on 19 June—the odds often skew heavily toward that player, yet Nishimura’s 1.01 betting price suggests even stronger confidence in her form [1][5]. Traders should watch for official start confirmations, as markets resolve to 50–50 if the match does not begin due to injury or walkover [3]. Key catalysts include the tournament’s daily schedule updates, any player withdrawal notices from the ITF, and live streaming availability, which can signal whether play is underway before the settlement window closes on 30 June 2026 [6][7].

Methodology

This page is a comparison snapshot: one live quote (Polymarket), 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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What does it cost to trade on Prediction Market UK?

Zero. Prediction Market UK routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How fast are USDC deposits?

How reliable are the quoted odds?
