The largest winning margin in Eurovision's 70-year history was set on Saturday 16 May 2026 in Vienna, when Bulgaria's DARA won the trophy with Bangaranga on 516 points — 173 clear of Israel's Michelle on 343. That figure broke two records simultaneously: the 165-point modern-era spread set by Ukraine's Stefania in Turin 2022, and Alexander Rybak's 169-point absolute-history mark set by Fairytale at Moscow 2009.
Why 2026's gap is structural, not a sympathy effect. Kalush Orchestra's 2022 win produced its 165-point margin almost entirely on televote: Ukraine's 439 public points alone exceeded the United Kingdom's combined jury-plus-televote score by more than 130 points. That was a wartime sympathy vote concentrated in one half of the scoreboard. Bulgaria's 2026 win was different — DARA won both halves of the vote: 204 jury (1st), 312 televote (1st). Only the third double-vote winner of the 50/50 era after Sobral (2017) and Loreen (2023).
What the market missed. Bookmakers carried Finland's Liekinheitin as a 2.00 (50% implied) favourite into the Grand Final. Finland finished sixth. Bulgaria opened the morning at 15.00 (~6.7% implied), drifted briefly to 16.00 after the Big Five rehearsal block, and was the only entry with a clear televote-pool dominance signal from the semi-final — nine sets of 12 from a single pool in SF2, the highest count ever recorded in a 50/50-era semi-final televote.
The pre-2016 absolute-margin context. Direct comparisons across scoring systems are messy because point caps and tie-resolution differed. But within the historical record under any system, Bulgaria's 173-point gap exceeds the previous holders: Norway 2009 (Rybak, 169), Norway 1985 (Bobbysocks, 21), Brotherhood of Man 1976 (UK, 17 under the old 1-to-12 system). Wikipedia's editorial layer now records the 173-point Vienna 2026 gap as the largest absolute spread in the contest's history under any scoring system.
Records broken on the night. 173-point margin (broken from 165). Most sets of 12 in a single televote pool in a semi-final (Bulgaria's 8+RoW in SF2, broken from 5+RoW). First double-vote winner since Loreen 2023. First Bulgarian Eurovision victory in 14 attempts. The 2027 contest moves to Sofia.
