US Open ATP: Arthur Gea vs Botic van de Zandschulp
Price history
Solid line: market price (fact). Dashed amber: our fair-value estimate.
Thesis
Why the estimate deviates from the market
- 1.Price momentum 1h: +0.00 logit, 6h: -8.07 logit, 24h: -7.17 logit (3 horizons, 67% agreement). [momentum v1.0.0, weight 0.27]
Counter-thesis
Why this may be wrong
- 1.Model confidence is 0.17; the estimate is shrunk heavily toward the market price and should be treated as weak.
Key catalysts
- 1.Resolution in 6.4 days; price convergence typically accelerates near expiry.
What would invalidate this
- 1.Market price moving to 0% 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 $174,631 would make the edge uncapturable regardless of accuracy.
