Swedish Open: Alejandro Tabilo vs Thiago Agustin Tirante

Platform comparison

Market context

Alejandro Tabilo faces Thiago Agustin Tirante in the quarter-final of the Swedish Open, a match originally scheduled for 9:30AM ET on 17 July 2026. The crowd-implied probability sits at 50% for Tabilo advancing, suggesting a tightly contested contest where the market has not yet priced in a clear favourite despite external modelling.

Historical data from predictive models offers a sharper lens for evaluating this 50% baseline. Dimers’ advanced tennis simulation currently assigns Tabilo a 56% win probability, indicating the crowd may be slightly underpricing the Chilean’s advantage [2]. Comparable quarter-final dynamics often see models outperforming raw crowd sentiment when one player holds a distinct surface or form edge, and the tip for both players to win a set further underscores the volatility expected in this matchup [1].

Traders should monitor real-time weather updates for Båstad and any late injury announcements, as clay-court matches are highly sensitive to environmental shifts. The settlement window closes on 24 July 2026, so conditional orders must account for the seven-day delay clause if the match is postponed. Programmatically, a bot should trigger a long position on Tabilo only if the live price dips below 52%, aligning with the model’s 56% edge, while hedging against the set-split outcome to mitigate variance [1][2].

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

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.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Bot UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
