ITF W75 Kursumlijska Banja 2 Women: Sofya Lansere vs Lisa Zaar

Platform comparison

Market context

The ITF W75 Kursumlijska Banja 2 tournament in Serbia is scheduled to commence on 13 August 2026, with Sofya Lansere facing Lisa Zaar in the women's draw. The 0% implied probability suggests either minimal trading activity or strong conviction that this match will not reach completion as scheduled. Given the settlement window extends to 20 August, there remains a seven-day buffer for the match to be played, though the current odds reflect significant uncertainty about whether the fixture will proceed.

ITF W75 events are lower-tier professional tournaments where match cancellations, withdrawals, and scheduling disruptions occur more frequently than on the WTA circuit. Historical precedent shows that Serbian summer tournaments occasionally face logistical challenges or player withdrawals due to travel constraints or injury. The absence of recent betting activity on this particular fixture—reflected in the extreme probability—may indicate limited public information about either player's current status or tournament confirmation details as of late July 2026.

Traders should monitor official ITF and tournament communications for confirmation of draw participation and any schedule adjustments. Player injury reports or late withdrawals typically emerge 48–72 hours before match time. The settlement rules specify that delays beyond seven days without a completed result trigger a 50-50 resolution, creating a specific risk boundary. Any announcement regarding venue changes, weather disruptions, or player fitness updates would materially shift the probability from its current extreme position.

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

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.

UK Frequently Asked Questions

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
