Active Market

An active market is a prediction market that is currently live and showing ongoing trading activity. Prices and participation are changing in real time.
background

In prediction markets, an active market is one where participants are actively placing trades. Prices continue to update, and new information is being incorporated into probabilities.

An active market is usually open, but openness alone is not enough. Activity implies meaningful trading volume and engagement, not just technical availability. Markets can be open but inactive. In contrast, active markets show visible movement in prices, volume, or participation.

Activity often increases around news, deadlines, or high-interest events. It may slow down during quiet periods or after major information is absorbed.

For analysts, active markets provide the richest prediction markets data. They are ideal for studying behavior, responsiveness, and belief formation.

Active markets produce the strongest signals. Knowing whether a market is active helps users focus on meaningful, information-rich data.

An open market allows trading, but it may have little or no activity. An active market shows ongoing trades and updates. Activity reflects engagement, while openness reflects availability. Analysts distinguish between the two to assess signal quality.

Indicators include recent trades, non-zero trading volume, price movement, and multiple active traders. Stable but inactive markets may show no recent changes. Prediction markets data provides these signals clearly.

Active markets are used for real-time monitoring, reaction analysis, and behavior detection. Analysts often prioritize them for alerts and signal extraction. Inactive markets are treated cautiously or excluded. Activity filtering improves data relevance.
