Market context

Aleksandar Kovacevic v Ignacio Buse is priced at 0% YES on Polymarket, which means the contract is trading as if a Buse advance is effectively impossible. On Polymarket, the position sits on Polygon and settles through USDC-based conditional tokens, so the key issue for holders is not who is favoured in the abstract, but whether the match is actually completed in a way that creates a clear winner before the settlement window closes.

The reading on 0% becomes easier when set against how tennis markets usually move late in a tournament. Once a semi-final is scheduled and a result is widely available, these contracts tend to converge sharply unless there is a retirement, walkover or timing issue. Here, live match listings and Tennis TV’s extended and short highlights confirm the Hamburg semi-final between Kovacevic and Buse has already been staged, which normally leaves little room for a delayed or ambiguous resolution. If a result is posted and ratified by the tour, that is the key data point for settlement rather than pre-match perceptions or ranking differences.

The main catalysts now are administrative rather than sporting: official ATP score reporting, any correction to match status, and whether the result is treated as completed, abandoned or void under the market rules. Sky Sports also carried the semi-final as a live item, reinforcing that this was a scheduled match rather than a future fixture. For Polymarket users, the practical watchlist is simple: confirm the final match status, check for any retirement language in the ATP record, and make sure nothing changes before the 7-day delay threshold tied to the market’s settlement mechanics.

Methodology

We track Hamburg European Open: Aleksandar Kovacevic vs Ignacio Buse 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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
