The second semi-final may not be as stacked but there is still potential for profit.
Ukraine are a rather generous 9/1 (8/1 Each-way) to win the second semi-final, which is very tempting given their draw and also the countries voting in their semi. They perform last in the semi-final, which is a little late but is still fortunate for Ukraine.
Historically, they poll well with Latvia, Moldova and Georgia, plus there are plenty of neighbouring countries in the second half of the semi which bodes well.
Latvia have a pretty difficult time of it late at Eurovision, they’ve failed to qualify for the final seven times since 2009. Given their rankings on Eurovisionworld’s site, the 5/4 available for them to miss out on qualification again looks a great bet. They’ve only had 166 nominations to win the competition from over 42k votes.
The Latvia entry has only had 381k views on Youtube, and despite them having a relatively decent position in the running order - I doubt they’ll qualify. Historically they poll well with Lithuania, Estonia, Ireland and UK, neither of which will be voting in second semi-final.
