Blackhorse Sentinel

Fact-check the take against the odds.

Sentinel Check: fact-check a public claim against labeled Polymarket odds, or odds-check a Fed rate call against the next-meeting book. Fed drift is a separate looking-back chart — the words, and inflation vs the line they named. Not a Blackhorse forecast.

Sentinel CheckFed drift

How it works

1. Paste institutional text

Fed statements, hearings, filings, earnings calls — drop the source in and run it.

2. Get commitment & certainty scores

See how locked-in the language is, and how sure it sounds — not a vibes take.

3. Spot the shift

Compare to prior meetings and baselines. Drift shows up as a number you can click through.

4. Export with a receipt

JSON or PDF, primary-source links, signed output you can send to a desk or a client.

Signal types

Commitment

must, shall, commit, target — language that locks them into action.

Room to move

may, allow, consider, flexible — discretionary language, not a promise.

Hard no

cannot, will not, reject — constraints that close doors.

Certainty vs hedge

Firm vs maybe language — how sure the text sounds.
