Cincinnati Open: Ashlyn Krueger vs Lois Boisson

Platform comparison

Market context

The Cincinnati Open match between Ashlyn Krueger and Lois Boisson, scheduled for 13 August 2026, has seen no material developments in the past 48 hours that would shift the 0% probability reading. Both players remain entered in the draw as of the latest WTA updates, with no withdrawal notices or injury announcements affecting either competitor's participation status.

Krueger, a mid-ranking American player, typically performs at her strongest on hard courts where the Cincinnati event is staged. Boisson, the French player, has shown inconsistent results on the WTA tour this season, with several early-round exits at comparable tier-one events. Historical precedent suggests that when two players of similar ranking face off at Masters 1000 level, the crowd-implied probability rarely settles at absolute extremes unless one player has withdrawn or a significant injury has been disclosed. The 0% reading here likely reflects either incomplete market information or a technical issue rather than genuine certainty about the outcome.

Traders should monitor the official Cincinnati Open draw updates through 12 August for any late withdrawals, which would trigger the cancellation resolution clause. Weather delays are possible given Cincinnati's August climate, though the settlement window extends to 20 August, providing a seven-day buffer. Any announcement regarding either player's fitness or participation status in the 72 hours before the match would be the primary catalyst to watch.

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.
