Figueira Da Foz: Alina Charaeva vs Ayla Aksu

Active sub-markets

Market context

Alina Charaeva and Ayla Aksu have already met in this Figueira da Foz event, and Aksu won that match 2-1, so the pricing is being read against an actual recent head-to-head rather than a neutral baseline.[5] Charaeva comes in with a stronger ranking profile, sitting around world No. 128 with a career peak in the mid-120s, and she has put together a solid 2026 results base across ITF and WTA-level play.[1][4][6] That makes a 100% YES crowd view understandable only if the market has effectively treated the fixture as settled elsewhere, because on tennis form and ranking alone the contest has not looked like a locked outcome.[1][2][4][6]

For traders, the main risk is not a normal pre-match injury story but whether the match was actually completed and recorded in time under the market’s settlement rules. If play was interrupted, postponed, or voided beyond the seven-day window, the market can still fall back to 50-50, so the relevant catalyst is the official tournament schedule and whether the women’s draw progressed to a completed result.[5] Charaeva’s recent match logs show she has been active on the circuit and handling a steady volume of matches, which is useful context but not a guarantee against an upset or an unfinished contest.[1][2][7] In other words, the key live variable is the tournament status of this exact pairing, not a broad form narrative.[5]

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
