For every NFL contract that trades as a LADDER of strikes — game spreads (KXNFLSPREAD), season win totals (KXNFLWINS) and player props — the Kalshi price at every listed strike beside our full probability distribution, and the derived verdict: SHAPE (we disagree about the tail, not the middle), LOCATION (we think the median sits elsewhere), PRICED (under 5pp everywhere), or PARTIAL (fewer than 3 model rungs). Ranked by the widest published gap. Our number is published only between 30% and 70% where it is measured calibrated; other rungs return the market only. Free, no key. Use for "where does the model disagree with Kalshi on the Rams spread", "which win-total rung is mispriced", "is the Kyren Williams rushing disagreement about the tail or the median", "biggest ladder gaps this week".
