How Does a Story and a Market Work?

On AllTop, the news and the odds share the same page. A story about the Fed's rate decision sits next to the market pricing that decision, and every market page carries the headlines that moved it.

A prediction market price is the wisdom of the crowds at work: hundreds of traders backing their read of what happens next with real money.

Read side by side, the news can tell you what happened and the price tells you how confident the crowd is about what comes next. This can sometimes happen before the next headline lands.

This describes how we sync stories and odds together into one unified view.

How does a story pull in a market?

On the homepage and topic pages, some stories carry a live market right alongside them. The backend matches relevant markets to news stories and attaches them to the story itself, so the odds you see riding next to a headline were placed there because they price that specific story.

This is the tighter of the two links: the story came first, and the market was attached as directly relevant.

How does a market pull in the news?

Event pages, game pages, and market boards pull in related news by matching the market's subject against the ranked news stories, and only stories that clear a real overlap make the cut. When a market page shows a related-news section, those stories earned their place by sharing the market's subject, not by loose association.

This link is looser than the first, because keyword overlap occasionally catches a story that mentions the same names without being about the same thing.

Why do the odds move before the news?

The two sides of the page run on different clocks. Market odds update in near real time, within seconds on a market page. News runs slower, on feed polling and a ranking pass that refreshes every few minutes. Because they aren't synchronized, odds usually move first.

Kalshi and Polymarket can reprice within minutes of an event while the story explaining it is still being corroborated, so a sharp price move with no fresh headline beside it usually means the news is still in transit.
