Price history

Solid line: market price (fact). Dashed amber: our fair-value estimate.

3 points

Thesis

Why the estimate deviates from the market

1.Mutually-exclusive (non-exhaustive) group of 36 markets sums to 106.0% against a constraint of at most 100% (+6.0pp overround); normalising implies 0.9% for this market. [cross_market v1.0.0, weight 0.98]

Counter-thesis

Why this may be wrong

1.Price momentum 1h: +0.38 logit, 6h: +0.38 logit (2 horizons, 100% agreement). [momentum v1.0.0, weight 0.27]
2.Model confidence is 0.25; the estimate is shrunk heavily toward the market price and should be treated as weak.
3.Only $0 of depth within 5% of mid; size is limited and slippage will reduce realised edge.

Key catalysts

1.Resolution in 264.6 days; price convergence typically accelerates near expiry.
2.Related-market inconsistency may resolve through arbitrage in either leg.

What would invalidate this

1.Market price moving to 1% 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 $90,902 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

This market will resolve according to the team that wins the 2026-27 UEFA Champions League Championship. If at any point it becomes impossible for a listed team to win the 2026-27 UEFA Champions League Championship per the rules of UEFA Champions League (e.g., they are eliminated in the playoffs), the corresponding market will resolve to "No". If the 2026-27 UEFA Champions League season is cancelled, postponed after June 19, 2027, 11:59 PM ET 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 UEFA Champions League; however, a consensus of credible reporting may also be used.
