Market outcomes
| ITF Kursumlijska Banja: Julia Avdeeva vs Elena Ruxandra Bertea | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Julia Avdeeva faces Elena Ruxandra Bertea in the ITF Women's tournament at Kursumlijska Banja, scheduled for 26 May 2026. The match is set for 3:30 AM ET, with settlement occurring by 2 June 2026. The current order book on Polymarket reflects a 0% implied probability for Avdeeva's victory, suggesting either strong backing for Bertea or minimal trading activity establishing a floor price. ITF tournaments at this tier typically attract limited liquidity, and such extreme probabilities often reflect thin order books rather than consensus conviction.
Avdeeva, a Russian player competing on the ITF circuit, and Bertea, a Romanian competitor, represent relatively comparable ranking tiers within lower-level professional tennis. Historical ITF Women's matches at Kursumlijska Banja have shown competitive outcomes across seeding levels, with unseeded or lower-ranked players regularly advancing. The 0% probability for Avdeeva warrants scrutiny given that ITF draws rarely produce such stark mismatches; comparable fixtures typically settle with probabilities between 25–75%, depending on ranking differentials and recent form.
Traders should monitor entry lists and official ITF confirmation closer to the event date, as scheduling changes and withdrawals occur frequently in lower-tier tournaments. Recent ITF tournament reports indicate fixture delays are not uncommon, particularly for early-morning slots. The settlement window extends seven days beyond the scheduled date, providing buffer for rescheduling. Any withdrawal by either player would trigger a 50-50 resolution, fundamentally altering current pricing.
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.

$10K 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.
