Figueira Da Foz: Alina Charaeva vs Ayla Aksu

Market context

Alina Charaeva and Ayla Aksu are scheduled to meet in the Figueira da Foz WTA 125 semi-final, with live listings placing the start at 11:30 UTC on 20 June 2026.[2][3][6] A market showing 100% yes is only consistent with one side already being effectively locked in by the live match state, because a clean pre-match probability would normally still leave room for scoreline volatility, cancellation risk, or an unresolved finish within the settlement window.[2][3][8]

For traders using scripts, alerts, or conditional orders, the practical read is to treat this as an event-driven market rather than a pure pricing one: the key inputs are whether the match actually starts, whether it is completed, and whether any retirement or abandonment changes the settlement path.[2][3][8] Comparable live listings and scoreboards show the match being tracked in real time across tennis platforms, which is exactly where automated monitoring should anchor its checks.[1][8][10]

The main catalysts are straightforward: official schedule updates from the tournament, any live score change, and any postponement that pushes resolution beyond seven days from the original date, which would force the 50-50 fallback under the market rules.[2][3][6] Tournament pages currently describe this as a semi-final, so a progression signal from the live draw or scoreboard is the most direct confirmation to watch.[1][3][10]

Methodology

We track Figueira Da Foz: Alina Charaeva vs Ayla Aksu on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
