Kauto set to be most expensive horse in history for bookies

A Kauto Star win in the Cheltenham Gold Cup would seal his position as the horse that has cost more money to bookies than any other in history.

If the record-breaking horse wins his third Gold Cup Ladbrokes reckon his career will have cost the betting industry upwards of £100 million.

The Gold Cup itself is worth £50 million in bets and is second only to the Grand National in triggering a punting frenzy.
