    Prediction markets and public expectations

    Prediction markets attach prices to possible outcomes of events. THodds brings together a sample of probabilities from Kalshi, Polymarket and Manifold, covering questions in politics, economics, technology, sports and other topics. Market prices reflect participating traders and forecasters, not a representative opinion poll or a guarantee of what will happen.

    What does a probability change mean?

    A move from 40% to 55% is an increase of 15 percentage points. The top movers rank the largest absolute 24-hour changes among fresh observations with available comparisons. A move may reflect new information, limited liquidity or an event approaching resolution; it does not establish the cause by itself.

    Why do platforms disagree?

    Questions may have different deadlines, outcome definitions and resolution rules. Participation and liquidity also vary. Similar titles do not establish that two markets describe the same event. Manifold activity is measured in play-money mana, while the other feeds report different activity units.

    How current and complete is the data?

    Collection is scheduled every five minutes. Coverage is a bounded sample, not every market on each platform. Recorded history begins when THodds first observes a market and is retained for 30 days. Missing comparisons remain unavailable, and stale observations are excluded from top movers. Hourly chart averages can differ from the latest probability.

    THodds currently provides observation and research; it does not place orders or accept deposits. Source methodology: Polymarket API, Kalshi API, Manifold API. Topics are estimated from question text. Metaculus is not connected. Watchlists are stored only in this browser.
