Market context

The HSBC Championships fixture between Jenson Brooksby and Martin Damm is scheduled for 16 June 2026 at 04:00 ET. The market currently reflects 100% implied probability for a match completion, though the settlement window extends to 23 June, allowing a seven-day buffer before resolution triggers the 50-50 tie-break clause. For automated traders, this means monitoring the official ATP or tournament schedule for any cancellation notices, which typically arrive 24–48 hours before play. The match outcome itself—rather than mere completion—determines whether the market resolves to either player's name.

Historical precedent suggests that grass-court tournaments like the HSBC Championships maintain fixture integrity at high rates; cancellations due to weather or player withdrawal occur in fewer than 3% of scheduled matches at this tier. However, injury withdrawals in the week preceding play are more common than outright cancellations, particularly for players ranked outside the top 50. Brooksby's injury history warrants tracking: he has withdrawn from tournaments mid-week on multiple occasions since 2023. Damm's recent form and entry confirmation should be cross-referenced against ATP official communications and tournament draw updates.

Traders implementing conditional orders should set alerts for ATP injury announcements and tournament schedule revisions published via the official HSBC Championships website. The 04:00 ET start time creates a narrow window for European traders to execute pre-match positions. Any announcement of a walkover or retirement mid-match would trigger the incomplete-match clause, requiring verification of which player advanced before settlement.

Methodology

We track HSBC Championships: Jenson Brooksby vs Martin Damm 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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
