Lay odds
Lay odds are the prices at which you can bet against an outcome on a betting exchange — the foundation of matched betting and arbitrage.
To lay is to take the other side of a bet: you act as the bookmaker for that selection, winning the stake if it loses and paying out if it wins. Lay odds are the exchange prices for doing so.
Lay prices are what makes matched betting and many arbitrage strategies possible, because they let you cover a back bet. OddsRelay pairs bookmaker back prices against exchange lay (Betfair, Smarkets, Matchbook) so the feed is matched out of the box.
OddsRelay delivers this as part of one already-matched feed. See live coverage on the coverage dashboard.
