Having fallen down the market for the competition this year, Bulgaria are back in favour with punters.
Prior to all of the Eurovision 2018 entries being confirmed, Bulgaria were the outright favourites at 5/1, with Bulgarian organisers saying at the time that their entry is "risky".
That proved to be the case once the act was confirmed to be EQUINOX with a song called Bones. Bulgaria dropped from that price of 5/1 to become outsiders at 20/1 in the space of two weeks.
EQUINOX have performed their song live a couple of times over the last couple of weeks however, at the London Eurovision Party and on Saturday at the Eurovision concert in Amsterdam.
That's piqued the interest of Eurovision fans everywhere, catapulting the Bulgarians back to the top end of the betting market. Indeed, over the last week Bulgaria have accounted for 18% of bets and their odds have been slashed from 14/1 back down to 5/1.
Israel continue to attract the most support though, with 21% of bets in the same period and remain 2/1 favourites to win the final in Lisbon on 12th May.
