Market context

Jan-Lennard Struff and Martin Landaluce are due to meet in the opening round at Mallorca, an ATP 250 grass-court event held at the Santa Ponsa Tennis Academy in Spain.[2][4][7] For market readers, the current 0% YES price implies the contract is already assigning no realistic path to Struff advancing, so the only way that changes is through a live feed showing the match is actually under way and resolving normally rather than being cancelled or pushed beyond the seven-day window.

Historically, this kind of price profile often reflects either a stale book or a fast-moving pre-match situation where the market has already digested the latest schedule and matchup data. Independent previews were split but leaned slightly towards Landaluce, with one model-style preview picking him to win and another noting initial odds that also favoured the Spaniard, while the players had no prior head-to-head record.[2][3] That matters for a programmatic approach: a bot should treat 0% as a signal to verify whether the order book is thin, whether the match has been completed, and whether the settlement logic has already shifted to a non-binary outcome.

The key catalysts are the official start time, any court-change or postponement notices, and whether the match begins at all on the published schedule.[2][5][7] At the time of the listed tee-off, sportsbook feeds had it down for around 9:00 am ET/13:00 UTC, which is the sort of timestamp a conditional-order workflow should monitor against live score and tournament-status APIs.[5][7] If the event is delayed beyond seven days from the scheduled date, or never played, the market resolves 50-50 rather than to either player, so automated monitoring should distinguish between “match started”, “match completed”, and “no contest” states rather than relying on score alone.

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 Polymarket App UK, which mirrors the Polymarket order book directly.

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.

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.

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?

Not under $1,500 of lifetime trading volume. Above that threshold, Polymarket App UK triggers a quick verification flow that finishes in minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
