France vs Morocco — World Cup Quarterfinal

KXWCGAME-26JUL09FRAMAR · Gillette Stadium, Foxborough MA · Kickoff 20:00 UTC (4:00 PM ET) · Assessed 13:00 UTC — pre-kickoff (~7h) · Conditions: sunny, 88–90°F, light wind, open-air
Committed pre-book (13:00 UTC, before any Kalshi fetch): P(France) 51% · P(Tie) 30% · P(Morocco) 19%.
France are the better side on talent and form, but Deschamps' pragmatism, Tchouaméni's likely absence, and 90°F heat point to a low-event game; Morocco's low block drags elite opponents to regulation draws far more often than "who advances" intuition suggests.

Research highlights

Why this leg

Anchoring transparency: search results surfaced sportsbook/odds pages (bet365, VegasInsider, SportsGambler) and a Sports Mole prediction of "France 1-0 after extra time." No numeric odds were opened or read before probabilities were committed; the Sports Mole narrative prediction was seen during team-news reading. Probabilities above are recorded exactly as first committed and were not revised after seeing the Kalshi book.
