Will they say the word? Markets where the edge is a transcript archive and a careful reading of the rules.
Mention markets settle on whether a specific person or broadcast says a specific word or phrase during a defined event: a debate, an earnings call, a press conference, an awards show. They look like novelty markets and occasionally trade like them, which is precisely the opportunity: unlike a football game, the underlying process here is often researchable in a way casual money never bothers with.
The core insight is that speech is habitual. Politicians reuse stump phrasing, executives reuse earnings-call vocabulary, broadcasters have verbal tics. Past transcripts are public. A mention market is frequently a base-rate problem wearing a novelty costume.
Settlement is source-and-criteria specific: the rules define whose speech counts (the named speaker only, or anyone at the event), what counts as the word (exact word, variants, plurals, possessives), and which recording or transcript is authoritative. Two markets that look identical can settle opposite ways on these details.
Timing windows matter: the event's official start and end define the counting window. Pre-show, post-show, and interruptions may or may not count. The rules say.
These books are thinner than sports. Spreads are wider, and a modest order can move the price. Maker patience is rewarded; market orders are punished.
Do the transcript work. For recurring speakers and recurring events, count the historical rate of the word in comparable past events. If a phrase appeared in 9 of the last 10 comparable speeches and the market prices it at 70 cents, you have a researched disagreement, which is the only kind worth funding.
Distinguish scripted from unscripted. Prepared remarks make word choice far more predictable than open Q&A. A market spanning both is really two markets; price the scripted portion's near-certainty separately from the Q&A lottery.
Watch for event-context drift: a word that was rare historically becomes near-certain when it is the news of the week. Casual money anchors on the old base rate; the informed side updates on the news cycle.
