Market depth
Backtest against the book, not the headline price
A fill has a cost the last trade never shows. ScoreTape records the live order book for sports markets on Polymarket and Kalshi, so your strategy sizes against the liquidity that actually existed at that moment.
- Every level, both sides — not a last price or a mid nobody could trade
- Forward-captured continuously; order-book history cannot be backfilled
- Replayable: snapshot time-series per outcome token via one endpoint

Why joined data
What it takes to model the college-football prediction markets
College football is huge, fast, and inefficient — wide spreads, scattered injury news, and a board that turns over every Saturday. CFB prediction-market data is only useful joined to the game and the report behind the price.
01
The join is the edge
Polymarket names a market with a slug; ESPN files the same game under an event id. ScoreTape welds the two and verifies it against settlement (99.96% agreement across sports). One request returns the market, the books, the result, the play-by-play, and the injury report as one document.
02
Depth on a wide board
With dozens of games a Saturday, the edge is in the book. ScoreTape records the live CFB order book on Polymarket and Kalshi, both sides, every level, so a backtest fills against the liquidity that actually existed. Depth and line movement are forward-captured and cannot be backfilled.
03
Injuries move the spread
College injury news is scattered and late — and the spread reacts hard. ScoreTape sweeps the league-wide report every 60 seconds and fires a signed webhook on every status change, filterable by team and status, with the full change-log archived.
