Market depth
Backtest against the book, not the headline price
A fill has a cost the last trade never shows. DepthFeed 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 Premier League prediction markets
England's top flight is the most-traded football league on Polymarket and Kalshi — and the deepest in our odds archive. Premier League prediction-market data is only useful joined to the fixture it settled on and the odds behind the price.
01
Inside the Premier League
Twenty clubs, thirty-eight matchdays, and the largest betting market in club football. The Premier League carries the richest historical record we hold: multi-book closing odds for every season since 2000/01, joined to the live prediction-market book trading today. The title race, the European places, and the relegation scrap each move the order book in their own way.
02
The join is the edge
Polymarket names a Premier League market with a slug; ESPN files the same fixture under an event id. DepthFeed's entity-resolution layer welds the two and verifies it against settlement — settled winners agree with the real result in 99.96% of checked games across sports. One request returns the market, the odds archive, and the result as one document.
03
Two decades of closing odds
DepthFeed serves a Premier League odds archive going back to the 2000/01 season — normalized multi-book 1X2, totals, and Asian-handicap closing lines from football-data.co.uk — through GET /v1/soccer/odds-history. Backtest a prediction market against the closing line for the same fixture, season after season, using consistent league, club, and fixture identities.
