Every market on Kalshi and Polymarket: sports, elections, politics, economics, financials, crypto, weather and entertainment, each with its outcome, its rules as written and a public page. Price history is backfilled from the venues; live order-book recording for every open market is rolling out. Where a market settles on words, as on earnings-call mentions, speeches, debates and hearings, Langbot also hears the event, attaches each phrase to the markets it touches and publishes the result on the coverage page. Nothing is hand-picked.

It reads the market's own rules. Kalshi earnings markets count words said by a company representative, the operator included, and never an analyst; a count strike such as Green Apron (3+ times) needs that many counting mentions. Each hit carries who said it, the mention count and a verdict, counts, doesn't count or unclear, with the reason. When the speaker's role is not certain the verdict says unclear rather than guess.

No. The verdict is a reading of the rules carried on the hit, not a settlement. Langbot never predicts an outcome, never recommends a trade and is never a named settlement source. It is evidence: a timestamped fact with a signed receipt that a resolver, a counterparty or an audit can check against the venue's own rules. Your agent decides what to do and trades under your own exchange keys.

Langbot does not claim to beat the market: on the mentions that count, the price often moves before or level with the fastest line. What is measured is the lead over the public webcast: on 13 October 2026, measured on the dial-in, Langbot led the public webcast by 5.9 seconds on the Goldman Sachs call and 10.2 seconds on the Citigroup call, across 3,596 aligned phrases. Over the last 24 hours on live streams a word became a fact 0.08 s after it was spoken, median, and within 0.2 s for nine words in ten. Each plan receives the same record at a published delay.

For each event Langbot looks for the fastest line it is allowed to hear: the dial-in for an earnings call, the committee or venue stream for a hearing, or the carrier that will air it. Nine carriers are watched for liveness every two minutes: the White House, the Fed, C-SPAN, ABC, CBS, NBC, CNBC, Bloomberg and Sky. An event still awaiting a line is listed as Line pending until one is attached.

Restricted sources, which include most earnings calls and broadcasts, yield facts only: the phrase, when it was said, the speaker's role and the markets it settles, with the raw text hashed and withheld. Public-domain and licensed sources can carry more. Every event on the coverage page shows the rights of its source, and every fact carries a signed receipt whatever the source.
