Methodology & Data Mapping
How we aggregate, normalize, and map cross-platform data
Default: Volume-Weighted Average Price (VWAP)
Weights each mapped market by its reported 24H USD volume at snapshot time. If volume is unavailable, we fall back to a simple average for that snapshot.
Use the VWAP/Simple toggle above the chart to switch aggregation views.
Kalshi: Official API (best bid/ask + last + 24H volume/liquidity when available).
Polymarket: Market data via their API (token prices + best bid/ask + 24H volume/liquidity when available).
Polymarket US: Gateway market data (yes/no prices + best bid/ask + market stats for volume/open interest where available).
Event data is updated hourly. Older history is downsampled.
Each event links one or more markets per provider. We normalize labels, map provider outcomes into a shared outcome list, and merge mapped markets where appropriate.
Cross-venue spread: Max–min difference across available venue probabilities for the same outcome.
Liquidity: Relative per-venue indicators based on provider liquidity fields (no depth/slippage modeling).
Arbitrage: Computed from best bid/ask when available (otherwise mid); after-fee spread applies the configured fee model only.

Patriots-Seahawks Prediction Market Volume Jumps from $5.8M to $105.5M in 24 Hours

Prediction Market NFL Trading Volume Could Reach $57 Billion This Season
DeFi Rate projects Kalshi NFL trading volume will reach roughly $3.2 billion through Week 1 and $57 billion across the full 2026–27 season. The forecast reflects the sharp expansion in prediction-market participation and NFL contract inventory over the past year, while using last season’s week-by-week trading pattern to model how volume is likely to build across the season rather than extrapolating the current growth rate indefinitely.
