Hamburg European Open: Felix Auger-Aliassime vs Aleksandar Kovacevic

Platform comparison

Active sub-markets

Market context

Polymarket is effectively pricing Felix Auger-Aliassime at certainty on this contract, with the market showing 100% YES and therefore no meaningful spread between the two outcomes. On Polygon, USDC collateral backs the conditional tokens, so the price mainly reflects whether Auger-Aliassime advances against Aleksandar Kovacevic before the settlement window closes, rather than any broader view on the tournament. If the match is played and Auger-Aliassime wins, the market resolves to him; if Kovacevic advances, it resolves to Kovacevic; and if the match is not completed within seven days of the scheduled date, it reverts to 50-50.

The historical frame is one of a heavy favourite meeting a lower-ranked opponent on clay. Bleacher Nation listed Auger-Aliassime at around -901, implying roughly a 90% chance, while Dimers put his win probability at 88%. That leaves the current 100% print well above third-party projections, so traders would usually read it as either a strong information lead or a stale, illiquid market rather than a normal pre-match estimate. A relevant comparison is the recent Hamburg result reported by Tennis Temple, where Kovacevic beat Auger-Aliassime in three sets at this event, showing the matchup is not automatic even when the Canadian is heavily favoured.

For traders, the main catalysts are line-up confirmation, any late withdrawal, and whether the round-of-16 scheduling changes. The match was listed for Hamburg on 20 May, and SofaScore showed a start time of 10:00 UTC, but tennis schedules can shift if earlier matches run long or weather intervenes. Kalshi-style resolution mechanics are straightforward: the contract only cares who advances, not set score or margin, so the key questions are whether the match is actually completed and whether either player pulls out before first ball.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), 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

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.
