Lil Uzi Vert's scheduled Friday performance at Lollapalooza in Chicago was cancelled due to heavy rain, ahead of headliner Charli XCX's set at the long-running festival. Weather disruption also forced the rescheduling of Zara Larsson's set, as organisers cited "weather issues" in an announcement made both on stage and via social media.

Despite missing his own slot on the T-Mobile Stage, Lil Uzi Vert made a surprise appearance later that evening during Major Lazer's performance on Perry's Stage, joining them for his 2022 single "Just Wanna Rock". Heavy rainfall continued into Saturday, delaying the festival's doors from opening until 2pm, with organisers warning attendees of muddy conditions in Grant Park and advising waterproof footwear.
