Market context
Polymarket is pricing the Tomljanovic leg at **100% YES**, so the contract is behaving as if Ajla Tomljanovic is already overwhelmingly expected to advance from this Lexus Eastbourne Open match. On Polymarket, that means USDC on Polygon is locked into a conditional token outcome that will settle on the named player if the match is completed with a winner, or revert to a 50-50 split if the match is not played, ends level, or is delayed beyond the market’s 7-day settlement rule.
That sort of near-certain price usually reflects either a confirmed result already embedded in the market, or a stale book where no one is left willing to sell the opposite side. Eastbourne itself is a standard pre-Wimbledon grass-court stop on the WTA calendar at Devonshire Park, running 22–27 June 2026, so schedule clarity matters more than ranking narratives once play is underway.[1][2][4] The key read for users is that a 100% quote leaves almost no spread for uncertainty, so any correction tends to come from official scoring updates, not from small changes in perceived form.
The catalysts to watch are straightforward: the WTA and tournament daily schedules, live score feeds, and any weather or backlog that pushes the match outside its planned slot.[1][3][8] Because the market description ties settlement to a specific scheduled match, a postponement, cancellation, walkover, or a match that is not resolved inside the 7-day window can flip the outcome away from a standard winner-takes-all resolution and into the market’s fallback 50-50 treatment.
Methodology
We track Lexus Eastbourne Open: Ajla Tomljanovic vs Elisabetta Cocciaretto 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.
