| ITF W100 Landisville, PA Women: Ava Catanzarite vs Martina Okalova | 2% |
Market context
Ava Catanzarite’s first-round qualifier against Martina Okalova at Landisville is the kind of ITF hard-court match where the market often moves on scheduling and lineup certainty as much as on raw level. The tournament is a W100 event on outdoor hard courts in Pennsylvania, and the live listing shows Okalova with the stronger ranking profile, while the market price has Catanzarite at just 2% implied, which is consistent with a clear underdog view rather than a close coin flip.[1][3][6]
For comparable ITF matches, the key read-through is that pre-start pricing can be unstable until the warm-up window closes: qualifiers are regularly affected by withdrawals, walkovers, and late court changes, and Landisville’s event window runs 3–9 August with the match listed for 3 August. A programmatic trader would usually poll the fixture feed and tournament status continuously, then only commit once the scheduled time, court assignment, and “ball in play” status are confirmed; if the match slips beyond the contract’s seven-day cutoff or is never played, settlement can revert to 50-50 under the market rules.[2][3][10]
The main catalysts are therefore operational rather than narrative: official start time, any change to the draw or qualifying order, and whether either player is visible as withdrawn in the live scores or tournament pages. Okalova’s recent schedule activity on tour and the live match listing indicate the pairing was expected to proceed, but for a bot or conditional-order workflow the decisive trigger is still the first point played, because that is what separates a live result from a cancellation-style settlement path.[1][9][10]
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 Polymarket Bot 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.
FAQ
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- 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 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 Polymarket Bot UK 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.
