Market outcomes
| ITF Lakewood: Kaylan Bigun vs Alexander Guajardo | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Kaylan Bigun faces Alexander Guajardo in an ITF Men's event at Lakewood, scheduled for 28 May 2026. The match is a lower-tier professional tennis fixture where both players compete for ranking points and prize money. Currently, Polymarket's order book reflects a 100% implied probability for Bigun's advancement, suggesting the market has priced in either a significant disparity in player quality or available information about form and matchup dynamics.
ITF tournaments at this level typically feature players ranked outside the ATP's top 200, where outcomes depend heavily on recent match fitness, surface preference, and head-to-head records. Bigun's current pricing at certainty is unusual for professional tennis, where upsets occur regularly even amongst mismatched opponents. Historical precedent from comparable ITF events shows that markets trading at extreme probabilities (95%+) often reflect incomplete information about player availability, recent injuries, or withdrawal patterns rather than genuine competitive certainty.
Traders should monitor official ITF and tournament communications through late May for any withdrawal announcements, which would trigger the 50-50 resolution clause. Surface conditions at Lakewood facilities and any late-stage ranking or seeding adjustments may shift the order book if new information emerges. The settlement window closes 4 June 2026, providing a week beyond the scheduled date for match completion, though delays beyond that threshold would also resolve to 50-50.
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.
The mechanics for trading "ITF Lakewood: Kaylan Bigun vs Alexander Guajardo" are the same as any other PolyGram sporting event contract. 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.
$488 in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for sports 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.
