Australia's commanding lead in the Second Semi-Final market stems from Delta Goodrem's polished power ballad "Eclipse," which earned strong jury and public backing during recent rehearsals and the jury show in Vienna. Traders have piled into the 69.5% implied probability after the Australian entry consistently topped post-rehearsal odds, reflecting its classic Celine Dion-style appeal that historically resonates with both televoters and professional juries. Ukraine sits second at 12.2% on the strength of Leléka's emotional "Ridnym" and the nation's consistent semi-final pedigree, while Bulgaria and Romania hold mid-tier positions around 10% and 6.5% respectively on the back of energetic staging and regional voting blocs. With the final set for Saturday, late momentum shifts remain possible if standout performances emerge in the remaining run-throughs.
