The Power of Unified Data

Which platform is better calibrated?

Run one query to find out. No manual data cleaning, no ETL pipelines, no schema mapping. We've already normalized everything.

  • Same events tracked across platforms with unified IDs
  • Resolution outcomes normalized for accurate comparison
  • Cross-platform price history at every timestamp
  • Event metadata and categorization included

Calibration by platform

Compare forecasting accuracy across all platforms

SELECT platform,
  FLOOR(probability * 10) / 10 as bucket,
  AVG(resolved_yes) as actual_rate,
  COUNT(*) as n
FROM unified_markets
WHERE resolved_at IS NOT NULL
GROUP BY platform, bucket

Use Cases

What researchers build with Probalytics

Forecasting Calibration

Study how well prediction markets are calibrated. Do 70% predictions resolve "yes" 70% of the time?

Market Efficiency

Analyze how quickly markets incorporate new information. Compare across platforms.

Crowd Wisdom

Research information aggregation dynamics. How do prediction markets outperform polls?

Cross-Platform Comparison

Compare the same events across all platforms. Which is most accurate?

SQL Access

Query data directly with SQL

Connect to our ClickHouse database directly. Run complex analytical queries, export results in any format.

  • Direct SQL queries to ClickHouse
  • Export results as CSV, JSON, or Parquet
  • REST API for programmatic access
