Market outcomes
| ITF Deauville: Corentin Denolly vs Felix Balshaw | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Corentin Denolly and Felix Balshaw are scheduled to compete in the ITF Men's Deauville tournament on 24 May 2026. The match represents a lower-tier professional tennis fixture within the International Tennis Federation circuit, where both players compete for ranking points and prize money. The current Polymarket order book reflects a 0% implied probability for Denolly's victory, suggesting traders are either heavily favouring Balshaw or pricing in significant uncertainty about match completion.
ITF Deauville matches historically attract modest liquidity on prediction markets given the players' relatively modest professional profiles and the tournament's secondary status within professional tennis. The 0% probability reading likely reflects either a thin order book with minimal backing for Denolly, or traders' assessment that Balshaw represents a substantially stronger competitor. Without recent ATP or ITF ranking data readily available, the current pricing may be anchored to previous head-to-head records or relative tournament seeding rather than updated form assessments.
Traders should monitor ITF official announcements regarding player withdrawals, which remain common at lower-tier events as players prioritise higher-ranked tournaments or manage injury concerns. The settlement window extends to 31 May, providing a seven-day buffer beyond the scheduled date to accommodate potential rescheduling. Weather conditions at the Deauville clay courts and any last-minute player fitness updates would constitute material catalysts affecting match completion probability, though such information typically emerges closer to the scheduled fixture date.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose. For "ITF Deauville: Corentin Denolly vs Felix Balshaw", the considerations above apply directly — Sports outcome contracts are sensitive to single-event variance — a coin-flip game, a referee call, or an injured player can move the line 10-30¢ in seconds. Position sizing should reflect that variance rather than the expected value alone.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
