Bastad: Mona Barthel vs Lola Radivojevic

Platform comparison

Market context

The tennis match between Mona Barthel and Lola Radivojevic at the Nordea Open in Båstad, originally set for 4:00am ET on 6 July 2026, has already concluded with Lola Radivojevic advancing 2–0. This outcome renders the prediction market “Bastad: Mona Barthel vs Lola Radivojevic” effectively settled, despite its formal settlement window ending on 13 July 2026. The current crowd-implied probability of 0% YES reflects the on-chain reality that Barthel did not win the match, making the contract a closed position for USDC holders on Polygon using conditional tokens.

Historically, prediction markets on Polymarket that reference completed matches but retain delayed settlement windows often see liquidity evaporate once the result is confirmed on-chain, as traders recognise the outcome is immutable. Comparable cases from the 2025 WTA season show that when a match result is verified via live-score feeds like Sofascore or TennisTemple, markets with 0% implied probability for the losing side typically remain at that level until formal resolution, with no speculative rebound.

Traders should monitor official WTA announcements regarding match cancellations or delays beyond seven days, which could trigger the market’s 50–50 resolution clause, though this is unlikely given the match was played and completed. Recent coverage from Tennis Majors confirms Radivojevic’s 2–0 victory, eliminating ambiguity. No further catalysts are expected, as the result is final and the on-chain token state already reflects the outcome.

FAQ

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi 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.
