Market context

The underlying event is the WTA 250 grass-court match between Janice Tjen and Caty McNally at the Lexus Eastbourne Open, originally set for 5:00 AM ET on 22 June 2026 at Devonshire Park in Eastbourne, Great Britain. The market resolves to the player who advances, with a 50-50 fallback if the match is cancelled, tied, or delayed beyond seven days without a winner. Settlement closes on 29 June 2026 at 09:00 UTC.

Historically, 50% crowd-implied probabilities in early-round WTA grass matches often reflect minimal pre-tournament data or evenly matched opponents, as seen in comparable 2024 and 2025 Eastbourne first-round fixtures where no player held a clear advantage before play began. Programmatically, bots treating this as a conditional order would flag the 50% baseline as a neutral entry point, waiting for live odds shifts once the match starts, since grass surfaces introduce high variance in early rounds that rarely supports strong pre-match edges.

Traders should monitor the official WTA daily schedule for any postponement notices, player injury updates, or weather-related delays, as grass tournaments are highly sensitive to rain. A recent WTA announcement confirmed the tournament runs from 22–27 June with no scheduled changes, but fans are advised to check live draws for lineup updates [1]. Programmatically, conditional orders would trigger only if the match begins within 24 hours of the original slot, avoiding exposure to extended delays that resolve the market to 50-50.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.

FAQ

How does resolution work?

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'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.

What does it cost to trade on Polymarket Bot UK?

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

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, Polymarket Bot UK triggers a quick verification flow that finishes in minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
