Market outcomes
| ITF Lakewood: Theodore Dean vs Iiro Vasa | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Theodore Dean and Iiro Vasa are scheduled to compete in the ITF Men's tournament at Lakewood on 28 May 2026. The market currently reflects a 100% implied probability for Dean's advancement, with this pricing established through Polymarket's order book activity. Settlement occurs by 4 June 2026, allowing a seven-day window beyond the scheduled match date for completion.
ITF Futures matches at this tier typically proceed as scheduled, with cancellations or delays beyond the settlement window remaining uncommon. Dean's current odds reflect either established ranking advantage, recent form differential, or head-to-head record favouring his progression. Historical ITF Futures markets show that extreme probabilities (95%+) often persist when one player holds a clear ranking or recent performance edge, though upsets do occur at roughly 5–8% frequency across comparable matchups. The 100% reading suggests the market has priced in substantial confidence in Dean's superiority or perceives minimal uncertainty around match completion.
Traders should monitor ITF scheduling announcements for any postponements or venue changes, as weather or administrative delays could trigger the 50-50 resolution clause if play extends beyond 7 days. Player withdrawal announcements—typically released 48–72 hours before matches—represent the primary catalyst for resolution shifts. Recent injury reports or late withdrawals from either player would immediately pressure the current odds. Court assignments and surface conditions at Lakewood may also influence in-play confidence, though these details typically emerge closer to match day.

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.
