Birmingham: Coleman Wong vs Filippo Romano

Platform comparison

Active sub-markets

Market context

Coleman Wong and Filippo Romano are scheduled to compete in a professional tennis match at Birmingham on 4 June 2026, with the settlement window closing on 11 June. The 0% implied probability reflects either minimal trading activity or genuine uncertainty about match completion within the seven-day resolution window. Settlement hinges on a decisive result: Wong advancing triggers a YES resolution, Romano's victory settles NO, whilst cancellation, ties, or delays beyond 7 June without a winner default to 50-50 parity.

Historical precedent from ATP Challenger and lower-tier events shows that weather disruptions at British grass-court venues occur in roughly 15–20% of June fixtures, though outright cancellations remain rare. Withdrawal or injury-related walkovers have affected approximately 8% of comparable matchups in the preceding two seasons. The current zero probability suggests traders either lack confidence in the match occurring as scheduled or have not yet priced in the underlying players' recent form and availability status.

Key catalysts include official tournament draw confirmation, injury reports from both players' camps, and weather forecasts issued within 48 hours of the scheduled date. Traders should monitor ATP and Challenger circuit announcements for any schedule adjustments or player withdrawals. From a regulatory standpoint, this market falls within German GlüStV scope if accessed from Germany; US CFTC reach applies to US-based participants, though prediction markets on sports outcomes occupy a distinct legal category from derivatives. The no-KYC threshold of $1,500 USD applies to individual positions on this market, meaning smaller traders can participate without full identity verification, though aggregate exposure and withdrawal thresholds may trigger compliance requirements depending on the platform operator's jurisdiction.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
