NEW: Prediction Markets API

One REST API for all prediction markets data

Scalar Market

A scalar market is a prediction market where the outcome is a single numeric value within a defined range. Traders forecast this number by buying and selling exposure tied to higher or lower final results.
background

A scalar market works by letting traders express beliefs about a future number—such as vote share, revenue, temperature, or performance metrics. Instead of choosing between fixed outcomes, traders decide whether the final result will fall higher or lower than current expectations. Their trades create a smooth forecast along a numeric scale.

As trades occur, the market probability curve adjusts to reflect how expectations shift across the entire range. Scalar markets often generate clearer prediction markets data than binary markets because they capture both the central estimate and the level of uncertainty. The market updates continuously as traders react to new information, forming a detailed picture of evolving sentiment.

Scalar markets are especially useful when accuracy matters more than a simple yes-or-no answer. They translate many individual signals into a single expected value, along with insight into how confident traders are about that value. This makes them powerful tools for forecasting quantitative outcomes.

Scalar markets provide a more precise view of future outcomes by focusing on numeric forecasts. They generate granular prediction markets data that helps analysts understand expectations, risk, and uncertainty across a full range of possibilities.

Platforms use scalar markets to forecast numbers rather than categories. This allows traders to express nuanced expectations and react to subtle information changes. Scalar markets also concentrate liquidity into one structure instead of many fragmented binary markets. The resulting prediction markets data becomes richer, smoother, and easier to analyze. For events with measurable results, scalar markets are a superior forecasting method.

Scalar markets generate forecasts by letting traders take positions that push the expected value higher or lower. As more traders buy exposure to higher outcomes, the market’s implied forecast rises. If traders expect lower results, the forecast declines. These movements create a continuously updating estimate of the final number. Analysts can review the full probability distribution to understand both the central forecast and the uncertainty.

Scalar markets reveal more than just a single prediction. They show how confidence shifts, how uncertainty widens or narrows, and how traders respond to major announcements. Analysts can observe gradual drifts, sudden jumps, or long periods of stability. This makes scalar prediction markets data especially useful for scenario planning, model calibration, and evaluating how information flows through a forecasting system.

A prediction market tracks the percentage of votes a Best Picture nominee will receive in a critics’ poll. Traders adjust their positions as screenings, early reviews, and festival reactions come in. The scalar forecast moves up or down to reflect the market’s evolving expectation of the exact vote share.
