Swedish Open: Andrey Rublev vs Luciano Darderi

Platform comparison

Market context

Andrey Rublev has already defeated Luciano Darderi 6–4, 6–3 in the final of the 2026 Swedish Open, confirming the match took place and concluded with Rublev advancing as the tournament champion [1][2]. The prediction market in question, which currently shows a 100% YES crowd-implied probability for Rublev, is effectively settled on-chain, as the real-world outcome is no longer uncertain. On Polymarket, this contract resolves to “Rublev” based on the final completed score, with conditional tokens on Polygon already reflecting the definitive result in USDC [6].

Historically, prediction markets that retain 100% pricing after an event’s conclusion indicate that the underlying outcome is confirmed and no further volatility is expected. In prior tennis markets on Polymarket, once a match result is verified via official ATP records, prices lock immediately, and conditional tokens become redeemable for the winning outcome without delay. This mirrors the current state: Rublev’s victory is documented in the official tournament record, eliminating any ambiguity about settlement [1].

Traders should monitor the official Polymarket resolution page for the final token redemption window, as the settlement deadline of 2026-07-26T12:00:00Z is now a formality given the match’s completion. No further announcements, schedule changes, or dependencies apply, as the match was played on 19 July 2026 and ended with a clear winner [2][3]. The on-chain mechanics will process the resolution automatically, converting Rublev tokens to USDC at the 1:1 rate for holders.

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.
