Price history

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

2 points

Thesis

Why the estimate deviates from the market

1.No independent signal currently supports a deviation from the market price; the estimate is anchored to the market.

Counter-thesis

Why this may be wrong

1.Model confidence is 0.00; the estimate is shrunk heavily toward the market price and should be treated as weak.
2.Only $0 of depth within 5% of mid; size is limited and slippage will reduce realised edge.

Key catalysts

1.Resolution in 25.6 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 $981,448 would make the edge uncapturable regardless of accuracy.
