Every prediction placed on Outcome, on one page. Who trades, what settles, where the money goes — and how your own record compares.
A question can have several outcomes; a market is one outcome.
Venue figures (traders, trades, volumes, open interest, markets and questions) come from Hydromancer's outcomeVenueStats for the Outcome venue. The tables, categories and YES/NO splits are computed from samples of settled outcomes returned by settledOutcomes: up to 100 across the venue, plus up to 100 per market category — this refresh asked for: sports, economics, esports, finance — samples, not the whole venue. Every category present in the sample with a non-zero volume is listed under "What people bet on"; a share under 1% reads "< 1%", nothing is hidden. Short-term price markets are recognised by their price template; everything else counts as a market people argued about. A market's volume is its YES plus NO notional volume; its traders are the larger of the two sides (people can trade both, so the sides are not added). A multi-outcome question is shown once, with its winning outcome. Category shares are weighted by volume.
"Open markets" lists the open markets with the most volume in the last 24 hours, from Hyperliquid's public outcomeMeta and spotMetaAndAssetCtxs, as of the daily refresh; YES is the last mid price, in cents (¢). A question can have several outcomes; a market is one outcome. Settled markets are shown all time, by volume, each with its settlement date (its last trade).
One server job refreshes these numbers once a day. If the latest refresh is older than 48 hours, the page shows "Data refresh pending" instead of numbers. Amounts are venue-wide totals, not anyone's wallet.
Open markets and settled outcomes come from Hydromancer (outcomeVenueStats, settledOutcomes). Volume is the amount traded on the permissionless venue since Aug 29, 2026, per Hydromancer; there is no canonical total Outcome volume, trackers use different formulas.
Three populations are named on this page and never mixed: the hero counts the whole venue (every settled market since Hydromancer's first recorded trade on the permissionless venue, Aug 29, 2026); "What people bet on", "How markets resolve" and the settled table are computed on the sample returned by settledOutcomes (its size is in each title; it includes markets settled before that date); "see all N sampled" counts the named, non-price markets of that sample. Trades and the average ticket come from the same outcomeVenueStats object as the volume, so they cover the same window. An open market whose resolution time has passed at the moment you read the page shows "awaiting settlement" instead of a price. In the open-markets table, when a row says "Leading: …" the price shown is that leading outcome's price, hence the column header "Leading · price".
"Published their record" lists only traders who submitted their HIP-4 record from this app (10 resolved markets minimum), shown by the short address prefix they published under. It is a self-selected sample, not the venue.
Settled markets archived daily since ; category and YES/NO shares will switch to the full archive once it covers 30 days.
