Analysis

Edge is only 3.7% (trimmed mean 16.2% vs price 12.5%), below the 5% trade threshold. The market's full bracket ladder is coherent and matches the agents' own central estimate: nowcast-implied YoY ~0.5% puts the mode in the 0.4–0.7 band (priced 50%), with this band as an upside tail dependent on an uncertain Irish rebound. No factual dispute a lookup could settle — the disagreement is distributional weighting of a genuinely uncertain volatile component. Sibling redirect considered: 0.0–0.3 band at 10% may be modestly cheap but its 0.17 spread kills tradability; 0.4–0.7 at 50% matches my estimate. My synthesis: ~15% for this band, essentially at market. SKIP.

Key Evidence

Q1 2026 revised to −0.2% QoQ / +0.3% YoY means Q2 needs ~+0.5–0.8% QoQ to reach the 0.8–1.1% YoY band; all July nowcasts (BNP +0.2–0.3%, Trading Economics +0.1%, Conference Board +0.2%) imply YoY ~0.4–0.6%, below the band. The only YES path is a large Irish statistical rebound in the flash — real but tail probability.

Risks

It's July 30 and the flash prints 0.8% YoY: Ireland's Q1 −12% collapse reversed sharply in Q2 (as multinational accounting distortions often do), adding ~0.5pp to the aggregate QoQ print and pushing YoY into the band — the exact tail path the low-probability agents underweighted. A NO trade at 12.5% would have lost on this Ireland rebound.
