Market context

Jan-Lennard Struff and Martin Landaluce were scheduled to meet in the Mallorca Championships’ opening round, with multiple score and betting listings placing the start on 22 June 2026. In a programmatic workflow, the key control is whether the fixture is merely delayed, completed, or pushed outside the seven-day settlement window, because those states drive a binary win for one player or a 50-50 resolution if no result is reached.[1][5]

A crowd-implied probability of **0% YES** is usually read as a stale or unpriced market state rather than a strong view that the underdog cannot win. For comparable ATP Tour first-round markets, a live-feed or sportsbook scrape would normally be used to confirm whether the match has already started and whether any retirement, suspension, or walkover has been recorded, since Mallorca match pages and highlights indicate the fixture was part of the tournament draw and had been completed or at least scheduled in the broadcast ecosystem.[2][3][6]

For traders running bots or conditional orders, the main catalysts are official tournament order-of-play updates, court assignment changes, and any late injury or withdrawal news, all of which can move a market from active to void-like settlement logic without a normal result. If the match is absent from live scoring but later appears in replay or highlights, that often signals completion rather than cancellation, so automated checks should prioritise the ATP schedule feed and live score status over secondary odds pages.[2][3][5]

Methodology

We track Mallorca Championships: Jan-Lennard Struff vs Martin Landaluce 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

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.
