Thesis

Why the estimate deviates from the market

  1. 1.Order book shows bid-side pressure (+14.3% imbalance within 5% of mid) on $178,215 of depth. [book_imbalance v1.0.0, weight 0.45]
  2. 2.Price momentum 1h: +0.00 logit, 6h: +0.00 logit, 24h: +0.04 logit (3 horizons, 33% agreement). [momentum v1.0.0, weight 0.18]

Counter-thesis

Why this may be wrong

  1. 1.Model confidence is 0.47; the estimate is shrunk heavily toward the market price and should be treated as weak.

Key catalysts

  1. 1.Resolution in 1.5 days; price convergence typically accelerates near expiry.

What would invalidate this

  1. 1.Market price moving to 56% would close the gap.
  2. 2.A reversal in the order-book imbalance or trade-flow direction that drove this estimate.
  3. 3.Liquidity falling materially below $178,215 would make the edge uncapturable regardless of accuracy.

Signal breakdown

Each signal is an independent estimate. Contribution is weight × logit distance from the market price.

Resolution criteria

Source: https://www.uefa.com/

In the upcoming game, scheduled for September 9, 2026 If Arsenal FC wins, this market will resolve to "Yes". Otherwise, this market will resolve to "No". If the game is postponed, this market will remain open until the game has been completed. If the game is canceled entirely, with no make-up game, this market will resolve "No". This market refers only to the outcome within the first 90 minutes of regular play plus stoppage time. The primary resolution source for this market is the official statistics of the event as recognized by the governing body or event organizers. However, if the governing body or event organizers have not published final match statistics within 2 hours after the event's conclusion, data from Flashscore may be used; if Flashscore data is unavailable, data from Sofascore may be used; if neither is available, a consensus of credible reporting may be used instead. All markets will settle based on the official final result as recognized by the governing body or event organizers. Revisions to officially declared final scores made after market resolution will not be accounted for in determining the outcome.
