Does DepthFeed cover the 2026 World Cup?

Yes. Every Polymarket and Kalshi World Cup market — including Kalshi's KXWCGAME per-match series — is recorded with full order-book depth and settlement, then resolved to the real fixture: final score and sportsbook odds where ESPN carries the match. The forward-captured tape cannot be rebuilt after the tournament, so the live book only exists on the record.

Can I backtest World Cup betting strategies with this?

Yes. Replay a World Cup market's order book against the closing line for the same fixture, then check the verified result — all resolved to the same game. The market-to-game join is verified at 99.96% where results are carried.

Backtest against the book, not the headline price

Why joined data

What it takes to model the World Cup prediction markets

The FIFA World Cup — the single highest-volume event in sports prediction markets, joined match by match. World Cup prediction-market data is only useful joined to the fixture it settled on and the odds behind the price.

Inside the World Cup

The 2026 World Cup, hosted across the United States, Canada, and Mexico, drove record volume on Kalshi and Polymarket. DepthFeed records every World Cup market — including Kalshi's KXWCGAME per-match series — continuously, and resolves it to the real match result. Because depth is forward-captured, the live order book of the tournament only exists because it was recorded as it traded.

The join is the edge

Polymarket names a World Cup 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 sportsbook odds, and the result as one document.

Depth is the truth

DepthFeed records the live World Cup order book on Polymarket and Kalshi — both sides, every level, continuously — so a backtest fills against the liquidity that actually existed, not a last price. Depth is forward-captured and cannot be backfilled once the fixture is over.
