Bastad: Irene Burillo Escorihuela vs Kaitlin Quevedo

Platform comparison

Market context

The WTA 125K quarterfinal in Båstad between Irene Burillo Escorihuela and Kaitlin Quevedo is set to begin tomorrow on the clay courts, yet the prediction market currently prices Burillo advancing at a 0% probability. This stark valuation on Polymarket, settled in USDC on the Polygon network via conditional tokens, suggests the market anticipates a cancellation or a non-play outcome rather than a competitive match, despite the players being scheduled for 6:00 AM ET.

Historically, similar 0% valuations in tennis prediction markets have preceded events where one player withdrew due to injury or where weather conditions halted play before the first ball was struck. In past WTA 125K tournaments, matches priced at absolute zero often resolved to the 50-50 tie clause when the event was cancelled entirely, as seen in previous clay-court seasons where rain delays exceeded the seven-day settlement window, forcing a null result rather than a winner.

Traders must monitor the official WTA withdrawal list and the local Båstad weather forecast for the next twelve hours, as these are the primary catalysts that will determine if the match proceeds. A recent update from Tennis.com confirms the quarterfinal is still listed as live, but any sudden announcement of a player’s injury or a shift in the Nordea Open schedule could trigger an immediate resolution to the tie condition, making the current 0% price a high-risk position dependent on on-chain event triggers.

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 PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is PolyGram. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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 Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
