Kalshi ladder

Market-implied mean on September 8, 2026: 3.70%. Settles at 8:30 AM ET on the printed headline YoY (one decimal, as BLS reports it). Implied mean = survival-curve integration of the “above X%” ladder mid-prices at the print’s 0.1pp granularity (engine connectors/kalshi.js).

Method

Before the print: every call as it stands on the tape, sealed into the receipt the evening before release (SHA-256 of the receipt JSON with its sha256 field removed). After the print: the scoreboard rows frozen at grading time — later revisions by any source never touch them. Graded against the BLS first release (YoY on the NSA index, MoM seasonally adjusted, one decimal). Signed error = forecast − actual.
