Market outcomes
| ITF Lakewood: William Kleege vs Alexander Guajardo | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
William Kleege and Alexander Guajardo are scheduled to compete in an ITF Men's tournament at Lakewood on 27 May 2026. The match is set for 3:00 PM ET, with settlement occurring at 7:00 PM ET on 3 June 2026. The current order book on Polymarket reflects zero probability for Kleege's advancement, indicating either strong conviction in Guajardo's superiority or minimal trading activity establishing a floor price. At this stage, the 0% implied probability likely reflects sparse liquidity rather than definitive assessment of the matchup.
ITF Futures events at this level typically feature players ranked outside the ATP top 500, where historical data on head-to-head records and recent form remains limited. Comparable Polymarket tennis contracts for lower-tier ITF matches have shown volatile probability shifts as match dates approach and additional information surfaces regarding player fitness or withdrawal patterns. The absence of established trading history on this specific pairing means the current probability should be interpreted cautiously as a starting position rather than a settled consensus.
Traders should monitor ITF tournament draws and player entry lists as the May date approaches. Withdrawal announcements, injury updates, or late scratches occur regularly in ITF circuits and can trigger resolution complications under the market's tie-break provisions. Recent ATP Challenger coverage from sources like ATP Tour's official schedule may provide context on whether either player has concurrent commitments that could affect availability or preparation.
This market settles from the official outcome published at https://www.itftennis.com/en/tournament-calendar/. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.

Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$3K in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for tennis contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
