Matched betting These are averages, not promises — a single offer can still lose. Matched betting uses bookmaker offers and exchange lays to hedge both outcomes. Done carefully it greatly reduces your exposure to the result, but odds can move and mistakes, exchange liquidity, commission or offer terms can still cause losses.
