Prediction Market Data Sources — 2026 Guide

The landscape in 2026

Prediction market data is now accessible from several distinct categories of source:

• Aggregation layers — combine multiple market sources into a consensus signal (Meridian Edge)
• Single-market APIs — data from one platform (individual regulated platforms)
• Community forecast platforms — question-based forecasting by trained superforecasters (community forecasting platforms)
• Regulated event markets — regulated prediction contracts with sports coverage

Source comparison

Meridian Edge

Best for: Developers who want structured, aggregated sports and event data via a clean REST API. Consensus probabilities across NBA, NHL, MLB, MLS, NFL. Divergence signals built-in. Starter tier: 100 calls/day.

Crypto-Native Platform

Best for: US political events and crypto-native applications. Public GraphQL API. Strong liquidity on major political and macro events. No sports coverage as of 2026.

Community Forecasting Platform

Best for: Long-tail question types and community-created markets. Fully open API, no authentication required. Lower liquidity means prices can be noisy.

Superforecasting Platform

Best for: Scientific, geopolitical, and long-horizon forecasts. Community-submitted probabilities, not market-traded prices. High-quality calibration research available.

Choosing the right source

For sports market data via API → Meridian Edge is the clearest choice. For US political forecasting → combine Meridian Edge with crypto-native platforms. For general research → superforecasting platforms provide long-horizon historical data.
