Mubadala Citi DC Open: Jessica Pegula vs Alexandra Eala

Platform comparison

Market context

Polymarket is pricing Jessica Pegula to advance at about 61% versus Alexandra Eala, with settlement on the Polygon network in USDC through conditional tokens. For a trader, that means the contract tracks a single binary outcome on whether Pegula wins the match, rather than any broader read on the tournament or player rankings.

The market sits in line with the pre-match shape of the contest: Pegula is the higher-ranked player, the top seed, and the only previous head-to-head meeting went her way in three sets at Miami in 2025. That earlier match is useful context because it showed Eala can keep the score close on hard court, but it also confirmed Pegula’s edge in the bigger points. Reports around the final also note Pegula’s experience in Washington and Eala’s first WTA 500 final, which helps explain why the market is giving the American the shorter price while still leaving room for upset risk.[2][10][16]

The main catalysts for repricing are simple: whether the final starts on schedule, any late withdrawal or retirement news, and how the live score develops once play begins. The WTA lists the final for Sunday at Stadium Court in Washington, and the contract’s rules matter here because a cancellation, tie, or delay beyond seven days would push resolution to 50-50 rather than either player.[2] That makes the settlement path as important as the tennis itself for Polymarket users watching the order book.

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

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.
