UK and Irish bookmaker prices: a sample snapshot

One snapshot, taken 11 October 2026 at 20:16 UTC, of pre-match prices from UK and Irish bookmakers, read from the OddsRelay odds API. It holds two views of the same moment: the raw board (each bookmaker's own markets, with outcomes named the way that bookmaker names them) and the standard matched board (every bookmaker's price on the same outcome under one name, with the line on line markets). Files: raw_prices.csv (one row per raw-board price: event, bookmaker, market, outcome, decimal price and when that market last changed), matched_prices.csv (one row per bookmaker price on the matched board: event, market, outcome, line, bookmaker, price), events.csv (sport, competition, start time in UTC, the two sides, the racecourse for races) and bookmakers.csv (key and name). raw_board.json and standard_board.json hold the same prices in the API's own JSON shape. DATA_DICTIONARY.md gives every column's type and meaning and what each market key means, datapackage.json is the Frictionless Data descriptor with each table's schema and keys, and summary.md says when the snapshot was taken and gives plain arithmetic on it, such as each bookmaker's margin on the football result market. The tables join on event_id and bookmaker_key. What it is not: a sample, so one moment with a few events per sport and a few markets per event, not a time series, and not a measure of what the OddsRelay feed covers (every count in it describes this snapshot only). Bookmakers only: every exchange, lay price and liquidity figure is left out. It is market data for building and analysis, not advice.
