Forecasting Data

Forecasting data is information used to predict a future outcome, such as a probability, a numeric estimate, or a range. It can come from models, analysts, or markets where people trade on what they think will happen.
background

Forecasting data is the kind of data you look at when you’re trying to answer a forward-looking question. Instead of describing what already happened, it describes what someone expects to happen next. That expectation might be a probability, like the chance of an event occurring, or a forecasted value, like an expected inflation number or a company’s future revenue.

You can think of forecasting data as a structured way to capture beliefs. Some forecasts come from statistical models trained on historical patterns. Others come from human judgment, like analyst estimates or expert panels. In some settings, forecasts come from markets, where prices reflect a crowd’s view and move as new information arrives.

Forecasting data usually includes more than just the prediction itself. It often includes timestamps, the forecasting horizon (when the outcome will be known), and the source of the forecast. Good datasets also track changes over time so you can see how expectations evolved. That history is important because it lets you measure how quickly forecasts react and whether they tend to drift.

Because forecasts are uncertain, forecasting data is often paired with measures of confidence or dispersion. Two forecasts can disagree even when they use the same underlying facts. That’s why comparison and evaluation are a big part of working with forecasting data. You typically want to know not just the latest number, but whether it has been stable and how it performed in the past.

Forecasting data turns uncertainty into something you can measure, compare, and analyze. It helps teams make decisions with a clearer view of expectations and risk.

One approach is to compare forecasts to the eventual outcomes and track errors over many events. You can also look at calibration, which checks whether probabilities match real-world frequencies over time. Consistency matters too, so analysts often measure how often the data revises and how large those revisions are. Reliable timestamps and clear outcome definitions make evaluations much more trustworthy.

Historical market data records what was traded or observed, like prices, volume, or spreads. Forecasting data is about expectations and typically includes probabilities or estimates about the future. The two can be combined, but they answer different questions. One explains what happened; the other helps you plan for what might happen.

Forecasting data can come from models, survey-style forecasts, analyst coverage, and prediction markets. Each source has trade-offs in speed, transparency, and how it reacts to new information. Some are updated on a schedule, while others update whenever beliefs change. Knowing the source helps you interpret the data and its potential biases.

A risk team monitors a dataset of event probabilities leading up to a central bank decision. When the implied probability of a rate hike rises from 30% to 65% over a week, they adjust hedges and scenario plans before the announcement.

FinFeedAPI’s Prediction Market API is relevant to forecasting data because prediction market prices can be interpreted as evolving probabilities. Developers can use these probabilities as a time-stamped forecasting signal, track how expectations change, and compare implied forecasts to the final outcomes. This supports research, monitoring, and applications that need structured forward-looking signals.
