Elina Svitolina defeated Coco Gauff 6–1, 6–2 in the Australian Open quarter-final on hard court on 27 January 2026, delivering a significant upset against the pre-match favourite. Gauff, who entered with odds of 1.5, was expected to progress, but Svitolina's dominant display—particularly in the opening set, which she claimed in just 32 minutes—proved decisive.

Svitolina's comprehensive victory represents a notable statement at a Grand Slam quarter-final stage and shifts momentum decisively in her favour heading toward the semi-final.
