Every card we publish carries its entry price, its timestamp, and a replay
query anyone can run to verify we bought what we said, when we said. Here is
the first one.
The Market Card
Viktor Halvorsen · lock: tomorrow 3:00 pm ET
MARKET: France vs Spain, World Cup semifinal — "Will France win on 2026-07-14?" (Polymarket)
SIDE & ENTRY: YES at 41.0¢ (CLOB best-ask, 2026-07-13 19:07:59Z)
WHY:
- Rest asymmetry — France played Thursday, Spain Friday; a full extra recovery day this deep in a tournament, where fatigue compounds.
- Pricing disconnect — books had France as the +135 outright tournament favorite pre-semis; bridging outright equity to a 41% single-match number exposes structural slippage.
- Roster mechanics — zero card suspensions off a low-exertion 2–0 clean sheet; Spain burned more to advance.
CONFIDENCE: 7.5/10
RESOLUTION & GRADE-BY: July 14, post-match (~5:00 pm ET) — result and Brier scored in the next daily.
WHAT KILLS IT: an early Spanish goal forcing France out of the low-variance block into a chase state.
The volume story: the France–Spain complex is doing roughly $14M of 24-hour volume across match, spread, and exact-score markets (fetched 19:07Z) — the deepest liquidity on the board, which is exactly where entry prices are honest.

The Board
One-line calibration reads — price vs base rate.
- Newsom, 2028 Democratic nominee — YES 19.85¢: RICH. "A nearly 20% implied probability for an open-field primary two years out severely underestimates the baseline entropy of political cycles."
- Fed cuts 50+ bps in July — YES 0.15¢: FAIR. "The market accurately identifies the tail-risk as near-zero — no macro data structure exists that would force a shock cut."
- Norris, 2026 F1 champion — YES 6.65¢: CHEAP. "Sub-7% fails to price the mechanical variance of the current leader against McLaren's chassis trajectory."
Coda

query so you can audit the entry yourself. "We will grade the Brier score on
