background

Real-time prediction odds show the immediate, up-to-date likelihood of an event according to active market participants. As traders process news, react to data releases, or adjust their views, their trades shift the odds moment by moment. This creates a continuously updating forecast that reflects how beliefs evolve in real time.

Platforms like Polymarket, Kalshi, Myriad, and Manifold produce real-time prediction odds during active trading. These odds react quickly to breaking developments—sometimes within seconds—making them one of the most responsive forecasting signals available. Over time, the odds form a detailed trail within prediction markets data that helps analysts understand market behavior, sentiment shifts, and information absorption.

Real-time prediction odds are especially useful for fast-moving events such as regulatory updates, political developments, economic releases, or breaking news situations.

Real-time prediction odds turn market activity into a live forecasting signal. They make prediction markets data more actionable by showing how expectations shift the instant new information appears.

They provide immediate insight into how the crowd interprets new information. Unlike polls or static forecasts, real-time odds update continuously as traders act on what they know. This makes prediction markets data far more responsive and reveals sentiment changes the moment they occur.

Real-time odds allow analysts to spot information shocks, identify rapid trend reversals, and detect when traders strongly react to new developments. These movements help distinguish meaningful signals from background noise. The resulting prediction markets data offers a clear, minute-by-minute view of belief formation.

Analysts can measure how quickly markets respond to events, identify uncertainty spikes, compare reactions across event categories, and evaluate overall forecast stability. They can also analyze whether markets overreact or underreact to news. These insights improve the interpretation of prediction markets data and strengthen forecasting models.

During a high-profile regulatory announcement tracked on Polymarket, the real-time prediction odds shifted sharply within minutes of new information being released. Traders reacted quickly, and the evolving odds gave analysts immediate feedback on how expectations changed after the announcement.

Real-time prediction odds rely on continuous, time-stamped forecast updates. FinFeed's Prediction Markets API provides structured prediction markets data—including live probabilities, historical paths, and outcomes—making it easy for developers to build real-time dashboards, alerts, and forecasting tools.
