Will Alexander Zverev win the 2026 Men's US Open?
Price history
Solid line: market price (fact). Dashed amber: our fair-value estimate.
Thesis
Why the estimate deviates from the market
- 1.Order book shows ask-side pressure (-74.6% imbalance within 5% of mid) on $4,761 of depth. [book_imbalance v1.0.0, weight 0.32]
- 2.Price momentum 1h: -0.01 logit, 6h: -0.04 logit (2 horizons, 100% agreement). [momentum v1.0.0, weight 0.27]
Counter-thesis
Why this may be wrong
- 1.Model confidence is 0.34; the estimate is shrunk heavily toward the market price and should be treated as weak.
- 2.Only $604 of depth within 5% of mid; size is limited and slippage will reduce realised edge.
Key catalysts
- 1.Resolution in 4.6 days; price convergence typically accelerates near expiry.
What would invalidate this
- 1.Market price moving to 26% would close the gap.
- 2.A reversal in the order-book imbalance or trade-flow direction that drove this estimate.
- 3.Liquidity falling materially below $4,761 would make the edge uncapturable regardless of accuracy.

Resolution criteria
The 2026 U.S. Open tennis tournament is scheduled for August 23 - September 13, 2026. This market will resolve to the player that wins the 2026 U.S. Open Men’s Singles Tournament. If at any point it becomes impossible for a listed player to win the 2026 U.S. Open Men’s Singles Tournament per the rules of the tournament, the corresponding market will resolve to “No”. If the 2026 U.S. Open Men’s Singles Tournament is cancelled, postponed after October 31, 2026, or there is otherwise no winner declared within that timeframe, this market will resolve to “Other”. The primary resolution source will be official information from the U.S. Open (https://www.usopen.org/index.html); however, a consensus of credible reporting may also be used.
