Explanation

How the trending board works

How markets are ranked

Most traded ranks open markets by dollars traded in the last 24 hours on Kalshi, Polymarket US and Polymarket together. A game is one row: its moneyline, with its spread and total at their main lines, and the same game on every venue that lists it, matched by sport, both teams and day. A spread, total or price ladder shows its main line, the one priced closest to 50¢. Recently closed shows Kalshi’s most-traded markets that stopped trading in the last 24 hours, with the winner once Kalshi has settled one; they carry no prices.

What the prices mean

Each price is that venue’s current Yes ask: what one contract costs right now, before fees. A contract pays $1 if its outcome happens, so at 80¢, $100 buys 125 contracts that pay $125 if it happens. We only show an ask from a two-sided quote observed in the last five minutes. “Not listed” means we didn’t find the market among that venue’s most traded in the last 24 hours; “no quote” means there’s no current two-sided price; “stale” means its last quote is more than five minutes old.

Why some quotes are held back

Before a price appears, it has to pass a consistency check. In a two-outcome market, a venue’s two Yes prices should add up to a bit over $1; if they add up to much more or much less, the sides are almost always swapped or stale. We also hold back any price far from every other venue, and any ask of $1, which just means nobody is selling. Held-back quotes are labeled “flagged” and never ranked.

What’s trading

Sports dominate day to day: games, spreads and totals settle within hours, so money turns over quickly. Politics, economics and crypto markets trade less each day but stay open for weeks or months. Weather and culture markets are small but steady.

Methodology

Markets are ranked by 24-hour volume on Kalshi, Polymarket US and Polymarket together; a game is one row across venues. Prices are each venue’s current Yes ask from a two-sided quote observed in the last five minutes. Quotes that fail our consistency check are held back and labeled. Full methodology →

Full methodology
PricesEach venue is priced at the midpoint of its bid and ask where our feed has both, otherwise at its last trade, and every source record says which.
AveragesHeadline figures average the venues that list the same outcome. A venue without a single matching contract is labeled “constructed” or left out.
Timestamps“Data observed” is when prices were read; “Updated” is when an editor last changed the text.
Stale quotesQuotes our data provider marks stale are shown but never averaged.
Activity, not depth24-hour dollars traded is recent activity, not how much you can buy at a price.
